[GENERAL] changing from postgreSQL 8.3 to 9.0
Hi, I have a database created on ver 8.3 an have restored the database in a new database in PostgreSQL 9.0. In the database i'm using a column storing "bytea". When trying to read the database with my java application, I have problems reading from the bytea-stream. Integers read is not correct. I can see that there is something new in ver 9.0: LC_COLLATE. Has that someting to do with my problem reading from "bytea". If so, what is the easiest way to get around this problem, when importing the database that is created in PostgreSQL 8.3? Kind regards, Paul
[GENERAL] Setting up tablepace
Hi all, I have a problem with setting up tablespace on a ramdisk. the ramdisk shall be used temporary for storing unprotected map data, that is normaly protected. I'm working in Linux. I have an ordirnary Linux user called normaluser, a user called chartuser (the ramdisk owner, the password is not known to the normal users), and a ordinary postgres user. Chartuser and root are the only ones that has access to the ramdisk. I have succeeded to store (as normaluser) the unprotected map files on the ramdisk, only accessable for chartuser. I would now like to import the map files to a GIS db that has the tabespace on the ramdisk. But I'm not able to create the tablespace on the ramdisk. Trying logged in as chartuser to run: psql -c "CREATE TABLESPACE ramspc LOCATION '/tmp/ramdisk0/tblspace'" "could not set permission on directory "/tmp/ramdisk0/tblspace": premission denied"... Any ideas, anyone? Thanks, Paul -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
[GENERAL] new databases using a template.
Hi,
I'm trying to create a new database by using a template database. But it is not
possible. The error code is that some one is using the template, but no one is
using it.
I'm using PgAdmin III ver 1.1.0. Has some one seen something like this?

Subject: Re: [GENERAL] Thoroughly confused about time zones
I think maybe I'm making things much more difficult than they need to be. I
tried this:
select cast (extract(epoch from ('2010-3-14 12:00'::timestamp - '2010-3-13
12:00'::timestamp)) as integer) / 60 / 60
and got 24. The difference between timestamps without time zones is 24 hours,
even though the interval spanned a time change.
But when I tried this:
select cast (extract(epoch from ('2010-3-14 12:00'::timestamptz - '2010-3-13
12:00'::timestamptz)) as integer) / 60 / 60
I got 23, showing that even if I did not specify what time zone I'm talking
about, I got the correct answer.

Subject: [GENERAL] metadata on a table
Hi,
I'm trying to read the metadata from table to create the same sort of table in
another database, using java.
This is how I do it today
quwstion = "SELECT * FROM table"
stmnt = dbConnection.prepareStatement(question);
rs = stmnt.executeQuery();
ResultSetMetaData rsMetaData = rs.getMetaData();
int numberOfColumns = rsMetaData.getColumnCount();
System.out.println("resultSet MetaData column Count=" + numberOfColumns);
int precision = rsMetaData.getPrecision(1);
String columnTypeName = rsMetaData.getColumnTypeName(1);
String name = rsMetaData.getColumnName(1);
String classname = rsMetaData.getColumnClassName(1);
The first object is the primary key with the name "fid",
columnTypeName = int4
I can see in the original table that fid has the type serial, which is an int4
(pgAdmin).
But when I create the table in the other database I would like to create it as
serial not just int4, how can I know that it is a serial?
Kind regards,
Paul

Re: [GENERAL] creating a table based on a table in stored in another database
I can add that I would like to do this in my java application.
E.i. just create an empty table in database1 which has the same column names
and types as a table stored in database2.
I tried this for a start:
stmnt = dbConnection.prepareStatement("select dblink_connect('myconn',
'dbname=gemaps')");
resultset = stmnt.executeQuery();
but got ERROR: function dblink_connect(unknown, unknown) does not exist

Create a schema-only dump and restore it into the other database.

[GENERAL] dumping parts of a database
Hi List, I have a database with two tables header and idata, they are connected with an conn_ID. I would like to dump header and the connected idata tables with a certain conn_ID. This I would like to import to the same type of database on another PostgreSQL server. I would be gratefull if someone could tell me how I dump those tables and how do I import them in another database? Kind regards, Paul
[GENERAL] Newbee to databases (ODBC)
Hi all,
I'm sorry to bother you with this question, I know it is a C++ ODBC
question. But I'm a bit desperate.
Perhaps I'll be lucky.
I have a table with 2 columns no_char and blobdata were no_char is
number of characters in blobdata. I would like to handle each row from
the result set.
I have got this far:
//Setup selectstatement
strcpy((char*) SQLStmt, "Select no_char, blobdata from tab1");
//Execute the statement
rc = SQLExecDirect(dbConnection.StmtHandle, SQLStmt, SQL_NTS);
//Define what to read out from the selection set
rc =SQLBindCol(StmtHandle, 1 SQL_C_LONG, (SQLPOINTER) &no, sizeOf(no),
NULL);
rc =SQLBindCol(StmtHandle, 2 SQL_C_BINARY, (SQLPOINTER) blob, no, NULL);
// get the values
while(SQLFetch(StmtHandle) != SQL_NO_DATA)
{
...
...
}
But this will not work since I'm using "no" in the second statement to
define the blob size, and no is not set yet.
I could solve it by using 2 different select statemen (once for the size
and one for the blob) but that seems to be a bad solution.
Sorry again!
/Paul
