LONG data types are difficult to work with. In V7, you can use a LONG with SELECT, the SET clause of UPDATE, and VALUES of INSERT, but there are several restictions. The LONG column CANNOT:
- be used in WHERE, GROUP BY, ORDER BY, CONNECT BY, or SELECT..DISTINCT
- be referenced by SQL functions (e.g., SUBSTR, TO_CHAR)
- be used in the SELECT list of a query combined with set operators (UNION, INTERSECT, etc.)
- be used in expressions
- be referenced when creating a table with a query
I avoid their use whenever as possible, as it is difficult to use a columns with these restrictions. Hope this helps.
