Hmm .... this is a classic RTFM, but the answer is here ...

if you are using dbms_sql then use "procedure dbms_sql.parse(c in integer, statement in varchar2s, lb in integer, ub in integer, lfflg in boolean, language_flag in integer);" syntax. This requires you to declare a local variable of type "dbms_sql.varchar2s". This type is essentially an index by table of varchar2(2000), so you are then pretty much limited by your creativity for the length of the sql statement. More information is available in $ORACLE_HOME/rdbms/admin/dbmssql.sql (it is a very good reading).

If you are using "execute immediate" thant I don't see what you'd have a problem with 4000 characters. You mention 4000, so I assume you are on 8i or 9i, then since Oracle 7x, the varchar2 variable is 32K-1 i.e. 32767 in pl/sql, way more than 4000 characters.

In either case, you win.
