[lazarus] Trouble at disconnect?
I've wrote a single application that connects with a Firebird database in a server in a windows XP network. From an initial form I go to another that only open a DBGRID and user can navigate forward and backward in a single browse or go to another form where the user can inform a search argument and the program executes a SELECT in the Firebird database and shows the result in a DBGRID. Well, while I navigate from the first form to any one of the other two and back to the first everything's run ok. When the user click in the exit button of the first form a execute the Self.Close method and the application/program freezes. The trouble seems to be that the program have troubles to disconnect from the remote server. If I run the same application in a local database no troubles occur. I have exposed this same trouble some days ago and can't have a solution. Then I am insisting in ask for help. Mainly because I'm trying to convince the bosses to use Lazarus here in the company. But this trouble is been used as an opposite argument. I'm having another trouble with the same application when using Firebird embedded server. The execution ends with an error, too. I think about ask you if there are no other attempts to make, trying to solve the trouble with the remote server and the embedded too. Thanks in advance.

IMHO, the problem is not in Lazarus, but in Firebird. The lazarus code does not care or even does not know where the firebird database is: The code for this is 100% the same. It is the gds32.dll (or fbclient.dll) code which is responsible for handling the close() call. The gds32.dll library (or fbclient.dll) decides that the database is remote if the database name is prepended with the hostname. That is all. If you connect to the database with some other too, e.g. flamerobin, you should experience the same problem.

It seems that the trouble occurs only when I put a database located in the windows XP network in my TIBConnection... Does this comment give new ideas?

[lazarus] Deleting ListBox items
I have a ListBox with four Items(for example). Suppose third item selected (ListBox1.Items [2]). When I run the method showed below program has different behavior: In windows it deletes the ListBox1.Items [2] (as expected). After the end of method execution, ListBox1 has three Items; In Linux it deletes the ListBox1.Items [2], ListBox1.Items [1] and ListBox1.Items [0]. After the end of method execution, ListBox1 will have one Item; Should this be a bug? Or am I doing something wrong in the linux version?

[lazarus] Why the results of both executions differ?

If you think carefully you'll conclude that there is only one type of TIMESTAMP: day, month, year, hours, minutes, seconds and 1/1e6 of seconds. All other types are derived from this format, the complete TIMESTAMP format. Another thought on the problems Arà has with update queries and TODBCConnection: as I need only read access, I never implemented UpdateIndexDefs; might that be required? UpdateIndexDefs? What is the function of such method? Since data base manager ever keep the index(es) up-to-date and it has the index(es) description in its areas, I can't imagine... To let modifications things work automatically, it is needed. This function updates the information about the indexes on the table. From this information it derrives what the primary key is. And the where part of the update/insert/delete statements is depending on the primary key... But you could also 'manually' add all fields-definitions, and then set the field that should be used in the where-clause of the sql- statement. I insist: management of indexes, primary keys, etc. are function of database manager. It administrates indexes, keys(primary and others), triggers and so on. I can't understand how you insist a treat these fields... Excuse me. Can you imagine if each programmer that accesses a DB2 table has power to treat indexes, keys and similar? How will these database be after one week? And after one month? At the end of the year. The internal attributes of the tables are protected from direct access of application programs. DB2 RDBMS make calculations of access paths, type of access, define access algorithms using the information of indexes and keys. It's important to remeber: The RDBMS do this. I'm not sure about that. The developer is asking for a Date/time, so he'll expect that he'll get a Date/time. If you need a string from DB2, I would use a cast in the sql-statement. I'm sure that if TIMESTAMP returns a string [26] any programmer can edit and transform this string as needed. If a developer is asking for a date/time format is easy: Convert it to date/time. You can treat these fields as you want. I suggest a string [26] because it seems to be more simple(I confess I have no idea how the interface is programmed and in which language). However if you INSERT and UPDATE rows in a table and a COBOL programmer(for example) access this table and find the format he expects(containing the fields I mentioned above), no problema!

But when I want some very specific information from the database that i can't get from a standard TDatetime (for example, I'm always using PostgreSQL that I like a lot, the timestamp can contain localized information, but not the TDateTime format) so what I do is that in my SQL query I'm casting the type to another type, like a string, so that I can proces the information manually by myself when required.

As you are programming for a procedural program, but event driven you can never know where a certain SQLQuery is used for at that moment. So if you change the SQL-statement of the query some strange things might Happen, leading to very hard to find bugs.

More over it must be thousands of other applications that would benefit of DB2 TIMESTAMP format. BTW, the format of TIMESTAMP in DB2 is -MM-DD HH.MM.SS.UU. IMHO, any other format seems to be not correct for DB2 approach. This sounds quite obscure to me; are those timestamps used as /unique/ keys? I never see they used as unique, but as a second column in a discret key. An example that I can remember now would be keep various questions done to a call center by the same user/customer... It would require some investigation to find out whether it is possible at all to do this. In the first place it would require a TTimeStamp implementation. Secondly, the ODBC driver should be capable of passing information about the precision of the timestamp. Thirdly, the TTimeStamp implementation would be required to support this precision information as well. Finally, it should somehow be possible to present the TTimeStamp in the -MM-DD HH.MM.SS.UU format in the GUI controls you use. A question guys: Why you don't treat TIMESTAMP as a string [26] in Lazarus? The ODBCConnection must be prepared to treat when write to table and when transfering from table to program. In cobol this DB2 type is treated in this way and there are thousands(millions) of programs running OK around the world(although I hate it, it seems that cobol will never die). I will take a look at the capabilities of ODBC to pass precision or format information of columns/data types. I'm open for any suggestions. I gave you mine suggestion above If I'm proposing things that are not possible to implement, please excuse me.

Customize the return format at Lazarus level(a TSQLQuery property? The way that CA-Realia cobol solves the trouble is customizing these format via Tools of the compiler) 2. Return always a format and people reformat as needed [ ] _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

I just didn't want you spending to much time questioning the ODBC connection. Ya! These whole story begins with a project of migration of a fourth tool of IBM mainframe(named COOL:Gen) to single cobol for MVS programs. We have the CA-Realia cobol installed in our local network and it emulates the mainframe environment. As I hate cobol(even being an expert) I wrote utilities in FPC and Lazarus. With the release 0.9.12 I discovered that Lazarus can access DB2 tables via ODBC. I wrote a Lazarus program to let the people that are testing the converted programs make alterations on DB2 tables in user-friendly format(DBNavigator + DBGrid). When I try to browse the 1st table containing TIMESTAMP Db2 columns the show begins. I'm using the same ODBC driver that is used for CA-Realia cobol (not simultaneous, of course). It is my understanding that the SQLdb currently does not support any PK type other than numeric. So I think Update, Delete would not work with a TTimeStamp. I'm not to sure how the insert would work. How I am only browsing the tables in sequential mode with Lazarus visual tools, there are no PK(primary keys envolved), I suppose. Am I wrong?

Re: [lazarus] Comments about DB2
I ask for enlighten too. The center of my solution is to use select * from tablename and let the DBNavigator/DBGrid does the insert, update and delete. In this way I could make a browse in any table. I simply must to change the SQL property of TSQLQuery. I use similar features with Firebird tables some months ago. Well... Firebird doesn't use ODBC in Lazarus... I'm totally confused at this time... I don't want to write one program for every DB2 table. I think that I'll abandon Lazarus for this task.

I then attempted to update the data using the sqlquery 'post', 'applyupdates' procedures. It immediately failed. However, select * from arcust work as expected. The reason the first fail and the second succeed was the lack of the PK being availabe to the sqlquery. When you open the sqlquery as in 'sqlquery1.open;' in the background a request is made to the database engine that returns the PK field name. I discovered this by reviewing the logs of the database engine (in my case that is a Postgres database engine). So when you update the data using the 'applyupdates' procedure the sqlquery control knows how to write the update statement. In other words sqlquery creates the update as follows: update table set field = something where PKfield = some number The opening of the sqlquery (sqlquery.open;) determined the 'PKfield' in the above statement. If I am incorrect could someone enlighten both of us!

The snapshots on http://www.de.freepascal.org/lazarus/ seem to include FPC 2.1.1 (right?). So I suggest, Arí that you download the latest win32 snapshot and give that a try. I am pretty sure this one would work. If this one does not work, I can try to install the DB2 database you mentioned in your last mail (thank you for the link!). Do you also use the ODBC driver from IBM? BTW, as a quick workaround for TIMESTAMP fields, you could perhaps try casting it to a DATETIME field (or whatever it is called in DB2). I downloaded the version from snapshot and install it in place of 0.9.12. Mr. Kuijvenhoven seems to be right the error with the TIMESTAMP column doesn't occur. Is time do more tests. Thank you Bram!
