the query fetches only 6 fields

Post by PHC » Fri 03 Dec 2004 11:37

Hi,

I have a kylix software running under linux connected to a mysql db.
I use the libsqlmda driver to access to the db (libsqlmda.so.2.10) I downloaded then trial version.

The problem is that when I run a query via a TSQLDataset, it fetches only the first 6 fields. The same problem appears when I run the demo program (ClientDataSet.dpr) from kylix.

What is the problem ??

Thank you for your help.

Linux Trial version of the driver is limited by number of the returned table columns. DbxMda trial version returns cursors with maximum 6 columns. Extra select-list columns are truncated.

so how to compare performance between your driver and the dbexpress driver if I can not do the same queries on complete tables ?
Isn't it possible to get a fully functionnal version to run a test under linux ?

Thanks

Can you send me a fully functional but time limited version too? I find the dowloadable trial no use in my case. Please extend it until January since we can't fully test it by this time (everybody is on vacation!!!). We are planning on buying 5 licenses if it meets our requirements.

Please send it to supermorzzz@yahoo.com.

I want to try it on my Attendance Monitoring System running 24/7. The default driver included in Delphi 7 limits 1 DBX component (xDataset) for each TSQLConnection. And this is causing a problem on the idle components, the connection gets dropped.

Thanks in advance.

Another question. Will your MySQL driver work on DBX for Delphi 7/2005 and MySQL 4.1? We are planning on upgrading by next year.

If you use Delphi, the last trial versions available for download from our site have time trial restriction (two weeks from the day of installation).

> Will your MySQL driver work on DBX for Delphi 7/2005 and MySQL 4.1?

Yes, we have already supported MySQL 4.1, support of Delphi 2005 needs some insignificant modifications in design-time.
