Retrieve a value generated by a Firebird generator (in other words, an
autoincremented value stored within the database) and get that
incremented value into a Pascal variable. The SQL code to increment
the value in the Firebird database is
SELECT (<generator>,<increment>) FROM RDB$DATABASE;
but I'm struggling to find a way to retrieve that incremented value.
Simply attaching a data source to the query returns zero rows when the
SQL is executed. I'm wondering whether I need to use a dummy table and
then use the generator to update a field, then retrieve the data with
a separate query.
Hi,
Use RETURNING clause with INSERT or UPDATE is a better solution.
Correct but this is not a solution if you just need the value, without INSERT
or UPDATE statement.
