[Lazarus] SQLQuery

[Chris Crori]

Done!
I used the second query method on the beforepost event and it works fine

I would like to try expanding the TSQLQuery to be able to use generator 
fields, can someone help me send the patch after?

Thank you Michael for your help

There is currently no way to do this unless you run a second query that uses
a unique field to retrieve the ID.

if you are using a manual insert query you can do
INSERT INTO YOURTABLE (fields) VALUES (yourvalues) RETURNING ID
and use a OPEN to retrieve the ID.

There are some plans to support such a thing but nothing was implemented
yet.

Michael.


There is a DBGrid linked to that Query so i can't :(
also i tried to use returning inside the InsertSql statement and it didn't
word (i thought maybe it will update the ID field)
