Re: [GENERAL] Import to excel to postgres based website?
I would recomend MS Access/ODBC. It works very fine both with linked Excel spreadsheets and PostgreSQL tables.

Users would be expected to have the xls ordered properly for the routine to work. It's something that would be pretty easy, given the right web platform, quite hard using the wrong one. Using perl, say, it would be less than a hundred lines of code. (Take uploaded file, crack xls format to extract data using one of the several CPAN excel reader modules, use DBI to insert it into the database). Uploading CSV (comma separated values) is likely to be easier in languages that don't happen to have support for xls, but CSV can only represent a small subset of xls. If the webserver itself it running on windows then there's all sorts of games you can play by remote controlling an instance of Excel, but doing that tends to be pretty fragile.

Hello. These days I was trying to temporarily disable triggers, too, and had much problems with ALTER TABLE..DISABLE TRIGGER ALL.

Turn off triggers for bulk load Issue: 9-3 [GENERAL] Turning off triggers ? 25-Nov-2002 Another issue with bulk loading is triggers firing with each row inserted. If you are sure your data is trustworthy and already meets your referential integrity requirements, you can turn off triggers for the bulk load and turn them back on immediately afterward. You should not use this option when your data is not completely clean. The reltriggers field in the pg_class table contains the number of triggers active for each table. It can be set to 0 the disable the triggers, but will need to be reset to the proper number of triggers to have them re-enabled.

Hello. Suppose I have a table tbl with columns (a, b, c, counter). And I have 5 ON UPDATE triggers assigned to this table. They process (a, b, c) columns, but never depend on counter. I need to update counter field, but I know that it is totally independent, so - for performance reason I want to temporarily disable all triggers during the tbl.counter updation. How could I do it? (Please do not offer ALTER TABLE tbl DISABLE TRIGGER ALL. It is NOT a production case: ALTER TABLE locks all the table during, so it cannot be used in heavy-loaded systems.) (Please do not also offer top move the counter to another table, because it is used in complex indices, e.g. INDEX ON (counter, a, c) to speedup fetching.) Possible solution: add an additional column named "disable_trg" BOOLEAN: (a, b, c, disable_trg). Then, I use the following UPDATE: UPDATE tbl SET counter = counter + 1, disable_trg = true WHERE a = 10; In each trigger I firstly run an instruction: IF NEW.disable_trg THEN RETURN NEW; END IF; And the latest trigger resets disable_trg field to NULL, so it is not written to the table. So, in some queries I may explicitly specify do I need to disable triggers or not. But this solution (the only possible?) looks like a brute-force method. Possibly Postgrs has another one, better?

I'm sure it's possible, but I'm not an expert on Windows batch command
language. There are some good references for that stuff on the
web--check them out.
To get the date in a format that should work for you in win2000 and
winxp, open a command prompt and type the following command:
FOR /F "tokens=2-4 delims=/ " %f IN ('date /t') DO (echo %h-%g-%f)
To get the same date format inside a .bat batch script, replace each %
sign with two % signs, like this:
FOR /F "tokens=2-4 delims=/ " %%f IN ('date /t') DO (echo %%h-%%g-%%f)
You can run a similar command to get the current timestamp as well.
For more information on how to do this, and to better understand the
commands above, open a command prompt and type "for /?"... you will
see a help screen on the FOR construct in the windows command shell.
enjoy:)

For example, how to restore in these two cases: A) pg_dump -f D:\MYDB_BCP -c -x -h localhost -U postgres MYDB B) pg_dump -f D:\MYDB_BCP -Fc -c -x -h localhost -U postgres MYDB Thanks. - Original Message - From: ketan shah To: pgsql-general@postgresql.org Sent: Wednesday, June 29, 2005 4:48 PM Subject: [GENERAL] how to use pg_dump and then restored onto development server Hi, All , I am newbie to postgres database.

My database name is otsdb.. For backup I use command Pg_dump otsdb > /home/Ketan/otsdbbkp.out But after successfully dump I cant see the otsdbbkp.out file in /home/Ketan/ If I get otsdbbkp.out file then I copy this file on my development server and then I issue the following command Psql d otsdb f otsdbbkp.out (my development server database name is otsdb) pl. help me .

Hi. Yes, you were right. I added lines for template0 and template1 into pgpass.conf file and now it works.

Perhaps its like this. pg_dumpall wants to dump the whole database-cluster (every database in your server) that is not only "MONITORINGZ" but the two templates, too. So pg_dumpall doesn't ask you for the password to your own database but 2 times for the pw for the 2 template DBs. In pgpass.conf write * instead of MONITORINGZ or copy the line for template0 and template1. Or don't use pg_dumpall and use pg_dump instead just for MONITORINGZ.

Re: [GENERAL] Pb with linked tables on PG8
Hello. I have experoenced the same problem. It seems to be common problem with Access connectiong to ODBC data source. It seems that Access has some problems to determine primary key... You should not use textual fields as primary key. Insted, add some bigserial (integer autoincrement field) into your tables and make such field primary key. Then relink your tables. This will solve your problem. Also, it is good to add timestamp field into tables. Also, be aware that your tables names should not be too long, because if they are long you will have problems with relinking. Access would not relink correctly (preassuming that you will use DSN-less and relinking on each startup). Bye. Zlatko For your information, this is explanation from MSDN: " ACC: "#Deleted" Errors with Linked ODBC Tables View products that this article applies to. Article ID : 128809 Last Review : May 6, 2003 Revision : 1.0 This article was previously published under Q128809 On this page SYMPTOMS CAUSE RESOLUTION MORE INFORMATION Steps to Reproduce Behavior APPLIES TO SYMPTOMS When you retrieve, insert, or update records in a linked ODBC table, each field in a record contains the "#Deleted" error message. When you retrieve, insert, or update records using code, you receive the error message "Record is deleted." Back to the top CAUSE The Microsoft Jet database engine is designed around a keyset-driven model. This means that data is retrieved, inserted, and updated based on key values (in the case of a linked ODBC table, the unique index of a table). After Microsoft Access performs an insert or an update of a linked ODBC table, it uses a Where criteria to select the record again to verify the insert or update. The Where criteria is based on the unique index. Although numerous factors can cause the select not to return any records, most often the cause is that the key value Microsoft Access has cached is not the same as the actual key value on the ODBC table. Other possible causes are as follows: Having an update or insert trigger on the table, modifying the key value. Basing the unique index on a float value. Using a fixed-length text field that may be padded on the server with the correct amount of spaces. Having a linked ODBC table containing Null values in any of the fields making up the unique index. These factors do not directly cause the "#Deleted" error message. Instead, they cause Microsoft Access to go to the next step in maintaining the key values, which is to select the record again, this time with the criteria based on all the other fields in the record. If this step returns more than one record, Microsoft Access returns the "#Deleted" message because it does not have a reliable key value to work with. If you close and re-open the table or choose Show All Records from the Records menu, the "#Deleted" errors are removed. Microsoft Access uses a similar process to retrieve records from an linked ODBC table. First, it retrieves the key values and then the rest of the fields that match the key values. If Microsoft Access is not able to find that value again when it tries to find the rest of the record, it assumes that the record is deleted. Back to the top RESOLUTION The following are some strategies that you can use to avoid this behavior: Avoid entering records that are exactly the same except for the unique index. Avoid an update that triggers updates of both the unique index and another field. Do not use a Float field as a unique index or as part of a unique index because of the inherent rounding problems of this data type. Do all the updates and inserts by using SQL pass-through queries so that you know exactly what is sent to the ODBC data source. Retrieve records with an SQL pass-through query. An SQL pass-through query is not updateable, and therefore does not cause "#Delete" errors. Avoid storing Null values within any field making up the unique index of your linked ODBC table. Back to the top MORE INFORMATION Note: In Microsoft Access 2.0, linked tables were called attached tables. Steps to Reproduce Behavior 1. Open the sample database Northwind.mdb (or NWIND.MDB. in Microsoft Access 2.0) 2. Use the Upsizing Tools to upsize the Shippers table. NOTE: This table contains an AutoNumber field (or Counter field in Microsoft Access 2.0) that is translated on SQL Server by the Upsizing Tools into a trigger that emulates a counter. 3. Open the linked Shippers table and enter a new
Re: [GENERAL] How to add an INHERITS to an already populated table ?
Hi. Recently I have tried to do the same thing and I coudn't include inheritence in existing tables. After a half of day of frustration, I have got an idea. I have successfully done it by using EMS PostgreSQL Manager Lite (you can download it from the net). There is an option "Duplicate" in EMS Manager, by which you can duplicate any table with all properties except foreign keys. During that process you can modify code (before Commit) so you can include inheritence in your new table. Then you delete original table, rename new table to old name and recreate foreign key... Well, I'm a newbie, so maybe someone more experienced offer you some better advice. If not, this will work...

Is it better to have one audit trail table that collects insert/update/delete of all audited tables, or it is better to have separate audit trail table for every audited table ? 2. To use triggers or rules ? Example for both ? 3. Could someone give me an example of a successfull audit trail solution ? I'm running on lack of time, so any help would be precious... Thanks. ---(end of broadcast)--- TIP 6: Have you searched our list archives? http://archives.postgresql.org
[GENERAL] PostgreSQL/MS Access - solution for passing parameters to pass through queries
Hi everybody! Recently I was struggling with client/server issues in MS Access/PostgreSQL combination. Although Access is intuitive and easy to use desktop database solution, many problems appear when someone is trying to use it as front-end for real server database systems such as PostgreSQL or MySQL. One of these problems is regarding pass-through queries and parameters. I wanted to have all the code on client, while executing it on the server in order to increase performance and speed. Therefore I created pass-through queriers for my forms and reports. The problem was that I couldn't pass parameters for where clause criteria, such as start and end-date. Therefore I have written procedure that passes parameters to pass-through queries. I hope it will help to those dealing with the same problem... For this method we use 2 saved pass-through queries.First, we have query with parameter name included in code in criteria expression. Then, we have another query which SQL string is generated from the first one. The SQL string is refreshed each time before query execution, so that parameter name is replaced with actual value. The form is based on that executive pass-through query... ' ' This code has a list of saved pass-through queries along with parameters.and can be called ' on Click event. ' Theprocedure calls function ParametersToQueries () that recreates SQL string of executive query.

Hello Mike.
I have found your code to be very usefull for me.
I combined it with some other codes in order to establich a procedure for
startup on client.
The problem apers with relinking tables. It seems that Access creates fake
indexes automaticcaly whern relinking using your proposed conncetion string.
So, I should disable that option, but don't know which option is that ?
Where can I find description of these constants in connection string (A, B,

I do the same thing with DAO and changing my querydef at run time, but I've
added a few 'enhancements'. First, I use a DSNLess connection - that way I
don't have to set up a DSN on each client's PC. Check out
http://gborg.postgresql.org/project/psqlodbc/genpage.php?howto-accessvba
for more info on it. Essentially, the connection string is generated from
a form that requests the username and password of the user. It looks like
this:
+
Dim strConnInfo as string, strConnUserPass as string, strConnParms as
string, strConnection as string
strConnInfo =
"ODBC;Driver={PostgreSQL};Server=MyServer;Port=5432;Database=MyDB;"
strConnUserPass = "Uid=" & Me.UserName.Value & ";Pwd=" & Me.Password.Value
& ";"
strConnParms = "A0=0;A1=6.4;A2=0;A3=0;A4=1;A5=0;A6=;A7=100;A8=4096;A9=1;"
& _
"B0=254;B1=8190;B2=0;B3=0;B4=1;B5=1;B6=0;B7=0;B8=0;B9=1;" & _
"C0=0;C1=0;C2=dd_"
strConnection = strConnInfo & strConnUserPass & strConnParms
++
Next, I created a function to create the query because I do it frequently:
++
Function DefineQuery(strName As String, _
strConnect As String, _
intTimeout As Integer, _
strSQL As String, _
boolReturnsRecords As Boolean _
)
'A function to create a query given the listed parameters
On Error GoTo ErrorHandler
Dim db As DAO.Database
Dim qrydef As DAO.QueryDef
Set db = CurrentDb
db.QueryDefs.Delete (strName) 'Delete the query first if it exists
'Create the query
create_query:
Set qrydef = db.CreateQueryDef(strName)
qrydef.Connect = strConnect
qrydef.ODBCTimeout = intTimeout
qrydef.SQL = strSQL
qrydef.ReturnsRecords = boolReturnsRecords
ErrorHandler:
Select Case Err.Number
Case 0
Err.Clear
Case 2501

MsgBox "Connection to database was lost. Please close and reopen
this program."
Case Else
MsgBox "An error occured in the function 'DefineQuery': " &
Err.Number & " " & Err.Description
End Select
End Function
+
Lastly, I dump the results of my passthrough query to a local table
because I found I got _much_ better response time that way when opening
the report that the data is used for. Again, I created a function to do
that:
+
Function TransferQueryToTable(strqryName As String, strtblName As String)
On Error GoTo ErrorHandler
Dim qryrs As DAO.Recordset, tblrs As DAO.Recordset
Dim I As Integer
'Define the recordsets we're working with
Set qryrs = CurrentDb.QueryDefs(strqryName).OpenRecordset
Set tblrs = CurrentDb.TableDefs(strtblName).OpenRecordset
'Make sure the table is empty before we fill it
If tblrs.RecordCount = 0 Then
qryrs.MoveFirst 'Make sure we start with the first record in the query
tblrs.AddNew 'Prepare the table for the first record

tblrs.MoveFirst
Do Until tblrs.EOF
tblrs.Delete 'Delete all records in the table
tblrs.MoveNext
Loop
qryrs.MoveFirst 'Make sure we start with the first record in the query
tblrs.AddNew 'Prepare the table for the first record
End If
'Loop through records
Do Until qryrs.EOF
For I = 0 To qryrs.Fields.count - 1
tblrs(I) = qryrs(I) 'Set each field in the table equal to each field in
the query
Next I
qryrs.MoveNext 'Move to the next record in the query
tblrs.Update 'Update the table
tblrs.AddNew 'Prepare the table for the next record
Loop
'close the recordsets
qryrs.Close
tblrs.Close
ErrorHandler:
Select Case Err.Number
Case 0
Err.Clear
Case 3021
MsgBox "No data available"
Case Else

Re: [GENERAL] MS-Access and Stored procedures
I was using ADO command object and both refresh method and method with
creating parameter object while working with Access Project...but I didn't
try to use it with PostgreSQL...
I would rather like to have all queries on client side anyway. Therefore I
use pass-through queries. But it doesn't allow using parameters (execept by
concatenation). Also, you can't base subforms on pass-through queries, so
now I use strange combination of local tables, append queries with
parameters based on pass-through queries etc. It works but I'm aware that it
is not very clever:)...
I think that it would be great if pass-through queries could accept
parameters. That would be a powerfull way for executing queries on client,
while keeping all the code on front-end side...But I doubt that Microsoft
will work on further Access improving anymore. It seems that Access is left
behind while VS.NET is top technology. Too bad...
IS there any good book covering MS Access usage as front-end for different
database servers except MSDE ?
Do you have form/subform/subform...based on stored procedures ? If so, how
do you synchronize form with subform ?

Zlatko

Hello...This is very interesting. I have also asked myself
how to prepare and execute stored procedures on POstgre from
MS Access.
Could you, please, give some example of Postgre function with
parameters that is executed as stored procedure from MS
Access? How would you pass parameters ? Using ADO Command object?
AFAIK, there are 2 ways to send parameters from Access to a PG function,
using ADO:
1. Write the parameters as the CommandText string:
Set cmd = New ADODB.Command
cmd.ActiveConnection = cnn
cmd.CommandText = "mypgfunction('this is a parameter', 25)"
cmd.CommandType = adCmdStoredProc
cmd.Execute
Set cmd = Nothing
The CommandText string can be the result of a concatenation:
Cmd.CommandText = "mypgfunction('" & strMyString & "', " & intMyValue &
")"
2. Another way is to use "true" ADO parameters:
Set cmd = New ADODB.Command
cmd.ActiveConnection = cnn
cmd.CommandText = "mypgfunction"
cmd.CommandType = adCmdStoredProc
Dim prm1 As ADODB.Parameter
Set prm1 = New ADODB.Parameter
With prm1
.Type = adVarChar
.Direction = adParamInput
.Value = "another string sent to PG"
.Name = "param1"
.Size = 30
End With
Dim prm2 As ADODB.Parameter
Set prm2 = New ADODB.Parameter
With prm2
.Type = adInteger
.Direction = adParamInput
.Value = 25
.Name = "param2"
.Size = 0
End With
cmd.Parameters.Append prm1
cmd.Parameters.Append prm2
cmd.Execute
Set cmd = Nothing

How can I use stored procedures (functions) with MS-Access
2002 connected to PostgreSQL 8.0 ?
An alternative to Philippe's solution is to use ADO.
Here is an sample function :
(assuming ActiveX Data Object lib is checked in the Tools/References menu)
Function ADO_PG()
Dim cnn As ADODB.Connection
Dim rst As ADODB.Recordset
Dim cmd As ADODB.Command
Dim strSQL As String
' Open connection
Set cnn = New ADODB.Connection
cnn.CursorLocation = adUseClient
cnn.ConnectionString = "DSN="
cnn.Open
' Display resultset (SELECT...)
Set rst = New ADODB.Recordset
strSQL = "SELECT * FROM a_function_returning_rows()"
rst.Open strSQL, cnn, adOpenDynamic, adLockOptimistic
While Not rst.EOF
Debug.Print rst("one column name here")
' Next record
rst.MoveNext
Wend
rst.Close
Set rst = Nothing
' Execute function (e.g.: INSERT, UPDATE...)
Set cmd = New ADODB.Command
cmd.ActiveConnection = cnn
cmd.CommandText = "another_pg_function()"
cmd.CommandType = adCmdStoredProc
cmd.Execute
Set cmd = Nothing
' Close resources
cnn.Close
Set cnn = Nothing
End Function
Of course, parameters can be sent to stored procedures.

Hy, in thread "Adventures in Quest for GUI RAD" there awnsered some Delphi - Developers. We actually use Delphi to access PostgreSQL too. But with some problems: The older Versions of microolab postgresql dac are absolutely trash. I haven't tried the newer ones. ODBC / Delphi BDE is ripped out by Borland. ADO is Microsoft and we look for a not Microsoft dependend product because are application also runs on unix (with Kylix). dbexpress is really hard to handle; I dont have extended experience with DBExpress and vitavoom - dbexpress driver. (www.vitavoom.com). we use zeos but the older version because of we found many problems in 6.X - Versions. I have fixed up many bugs in zeos 5.4 so it now works fine with postgres.(7.3-8 running) All in all i have to say Zeos works but i'm not really happy with zeos because it seems not clear if it has a future. Components are very inefficient, every time you open a table all configuration / table meta data is fetched. No internal caching or sth like this. (they are still faster than dbexpress / odbc / Zeos6.X) Fields with unknown length are mapped wrong. and so on- With Zeos 6.X you cannot use Postgresql - search path because 6.X Versions always wrote schema name before table name. 6.X does not support Cursor Fetch. 6.X isn't speacially for postgres, they try to support all bigger databases. Has anyone tried .net - pgsql - driver with Delphi 2005? All in all my opinion is that there is no really good solution to access Postgres from Delphi.

Re: [GENERAL] [INTERFACES] calculated identity field in views, again...
Hello. Thanks for answers... After considering all proposed, I think that it is probably possible to give MS Acces some composite primary keys while linking views as tables, in order to help Access not to fall into "#deleted#", but it would take some extra time to experiment with every view. In meantime, I successfully implemented solution with local tables. Append queries based on pass-through queries are triggered and local tables are refreshed. It seems to be fast and reliable...

I have an MS Access front-end for a database on PostgreSQL. I could use pass-through queries as record sources for reports and it works fine... Unfortunately, MS Access doesn't allow pass-through queries to be records sources for subforms. Unless you use unbound form/controls. Which means handling everything in code, which might work out best for you, depending on what you want (this is effectively equivalent to the VB-only option which someone else mentioned). Therefore I tried to base subforms on regular JET queries on linked tables. It was too slow... Then I tried to base subforms on DAO recordset code generated from pass-through QueryDef objects. Although it worked, it was very unstable... Now it seems to me that POstgreSQL views are the best solution, but Access considers views as tables (!) and needs column with unique values. AFAIK a composite key (combination of several columns) should work ok for a primary key for Access. When linking to the view, just select the columns you want to use. Or are you saying that you tried this, and it didn't work? Alternatively, you could try including in your view definition the oid column for each of the constituent tables. If I understand right, oids are globally unique within your database. This assumes that you have created your tables with oids, which may not be the case. Basing a subform on a mult-table join sounds like odd database design. Perhaps if you can explain more about what you are trying to do, people can offer more suggestions. All those views are complicated queries on several tables, so I can't use any table's column as primary key. I need a calculated column in the view that Access will consider as primary key column. In regular tables, I use bigserial field, but how can I create calculated bigserial column in a view ?

You would have to create a sequence and reference it with
nextval('sequencename') in your view. But I doubt very much that it will
do
anything useful.
It sounds like Access wants to be able to update records by looking them
up by
primary key. In that case assigning a new value in your view will make
Postgres make up a brand new number that is utterly useless for finding
the

Re: [GENERAL] psqlodbc MSAccess and Postgresql
Hello, I am currently migrating my MSDE/Access (Access Project) aplication to PostgreSQL. I have experienced a lot of obstacles till now, but anyway it seems quite posible to make a good aplication by this combination of Access front-end and PostgreSQL base. I use the following ODBC settings for linked tables successfully: [ODBC]DRIVER=PostgreSQLUID=zmaticUseServerSidePrepare=0ByteaAsLongVarBinary=0BI=0TrueIsMinus1=1DisallowPremature=0UpdatableCursors=1LFConversion=1ExtraSysTablePrefixes=dd_CancelAsFreeStmt=0Parse=1BoolsAsChar=1UnknownsAsLongVarchar=0TextAsLongVarchar=1UseDeclareFetch=1Ksqo=1Optimizer=1CommLog=0Debug=0MaxLongVarcharSize=8190MaxVarcharSize=254UnknownSizes=0Socket=4096Fetch=100ConnSettings=CLIENT%5fENCODING%3dWIN1250ShowSystemTables=0RowVersioning=1ShowOidColumn=0FakeOidIndex=0Protocol=6.4ReadOnly=0PORT=5432SERVER=localhostDATABASE=MyDatabase Tips and tricks: 1. Disable "Recognize Unique Indexes" every time you link tables. That will allow you to give proper primary keys to Access (you will be prompted). Otherwise, Access do it quite bad. 2- Use Row Versioning 3. Every table must have numeric primary key. Don't use text field as primary key. Access will be confused and you will have "#DELETED#" in your tables. 4. Instead of having JET queries on linked tables, it is better to have good pass-through query. But it doesn't accept parameters, so you will have to combine regular JEt queries with pass-through queries. I use pass-through queries and server-side functions (for calculated columns) that prepare recordset and then filtrate it by regular JET query additionaly (for example: start and end date)... Other possibility is to use server views linked as tables in Access...

Mike, your post helped me to discover psql command window, I had been trying out the pgAdmin ... I found an interesting article regarding MSAccess as a front end to Postgresql, so I downloaded the psqlodbc installer. I will be getting up the nerve to run the install and go into windows odbc and install that driver so I can use MSAccess with Postgresql ... any tips or caveats appreciated This is the link which is guiding me http://database.sarang.net/database/postgres/postodbc/faq.html
[GENERAL] Calculated bigserial column in a view
I know that it sounds crazy, but I need a bigserial coulumn in a view that is consisted of several tables. That column should not be based on bigserial column of any table, but should be a calculated column... How can I accomplish it ? Thanks in advance. Zlatko
Re: [GENERAL] bigserial field in a view, nextval function ?
Well, my front-end is MS Access, and Access sees views as tables. When I have forms with subforms there is a problem with linking them if table has no primary key. As Access thinks that a view is a table, I need a primary key in the view. Also, Access doesn't like text field of ODBC-linked table to be primary key (#Deleted phenomena#). Instead, it should be a numeric field. Therefore, I would like to have an autoincrement field, which Access will consider as primary key...I need a calculated bigserial field... Can I accomplish it whith nextval ?
