Lazarus 2.0.12 dies when editing SQL
« on: March 10, 2021, 10:23:37 pm »
Hi,
When editing SQLtext in a TSQLQuery-component and when getting an error in the SQL, Lazarus 2.0.12 dies. Anyone seen this behaviour on Windows 10 running a PostgreSQL 12 connection?

Br,
Niclas

Not when changing the SQL-Property.
But Lazarus gives me an Access Violation, when i have a TSQLQuery-Component, which is set to active in the OI, and when i try to set it to inactive in the Object-Inspector, Lazarus goes BOOM.

Bottom Line: Don't set anything of the TSQL-Trinity to active in the OI. Only from Code.

Have you reported this as bug? Is it specific to a DB component set?

It is already reported many times. See :
 https://bugs.freepascal.org/view.php?id=38352
and its related issues.
Particularly nasty to fix.

Mostly Lazarus trunk and FPC 3.2 on Manjaro Linux 64-bit.

It's fixed in FPC trunk.

Does it not need any changes in Lazarus components? Maybe not, good so!
The reports, or at least one of them, can be open for a while. Otherwise somebody will report the same issue again.

I spent almost an hour fixing the issue, when I noticed that the bug is already fixed.  :) Another hour wasted...

No, the bug is in BufDataset.pas(FPC).
