I would like to check, is it possible to left join two tables using a non numeric column?
i.e. where descriptions_cd is a varchar(10) and table_cd is a varchar(10):
SELECT *
FROM descriptions d
LEFT JOIN tables t ON t.table_cd = d.descriptions_cd;
This SQL seems to be giving an ora-01722 error. This is in Oracle 9i.
ok, table_cd is not numeric. that explains.
