[Solved] INSERT RETURNING an_id
«
on:
March 11, 2020, 10:05:15 pm »
I've followed the wiki
https://wiki.lazarus.freepascal.org/postgres#How_To
hoping to get this working:
Query.SQL.Text:= 'INSERT INTO myschema.films(film_name)' +
'VALUES(:film_name) RETURNING film_id;';
Query.Params.ParamByName('film_name').AsString:='Mission Impossible';
Query.Open;
ID:= Query.FieldByName('film_id').AsInteger;
However I always get the error message:
SQLQuery: field not found "film_id"
.
What am I missing here?

You don't have a column called 'film_id' which is integer primary key with autoincrement/autovalue?

Try using quotations... i.e.
Returning "film_id";
I do not know exactly, but I experienced similar problem. PostgreSQL seems to require " " when the name contains _. Also it may be case-sensitive.
If this still do not work, try films."film_id".

I isolated the case and got it working. Need to figure out why it's not working in a more complicated world.

Some clarification
Before assigning the SQL.Text, make sure the query is closed. When this is not the case, subsequent calls to the insert query will result in the same id.
The insert sql needs to be self standing, i.e. in case a datasource is associated with it, will not work
