[Solved]TSQLQuery Error reading Query1.FieldDefs: Unknown Property FieldDefs lazarus / 16-Databases ---------------------------------------------------------------------- T90 · 2012-04-16 07:21 Hello, I have a form with multiple TSQLQueries and everything worked fine until I upgraded to Lazarus 0.9.30.4. After upgrading after opening one of the queries I got the error from the topic. The strange thing is the other queries are working fine. I downgraded to Lazarus 0.9.30.2 back but the error is still there. Currently using Lazarus 0.9.30.2, Windows XP SP3 ---------------------------------------------------------------------- T90 · 2012-04-16 07:42 The problem is that somehow (maybe the upgrade to Lazarus 0.9.30.4 did it) FieldDef = <> entries appeared in the forms' LFM files. All one should do is remove those entries.
