Hi Helen

My problem is to get a id inserted before (or after) execute a insert sql
... I still did not understand how to obtain it when I use threads ...
About the method ExecuteDML ... it is only to ilustrate .. but how you do to
execute a insert query? Can you show me an example to get a id inserted and
how to use ib_query to execute a insert query? I have to use GeneratorLinks
property for this?
I don´t use double quotes ... it is because delphi requires this ... one o
close string and other to close the query ...
