Single row SELECT
Informix®
With Informix, you must use the system table with a condition on the table id:
SELECT user FROM systables WHERE tabid=1
SAP HANA®
To retrieve a single row with SAP HANA, use
DUMMY
table:
SELECT user FROM DUMMY
Solution
Check the BDL sources for "FROM systables WHERE tabid=1
" and use dynamic SQL to
resolve this problem.
Consider writing a FUNCTION
which produces the FROM
and
WHERE
part, depending on the target database type.
