Re: Dynamic SQL

Yes, I know it's 32767.
My code:
PROCEDURE ...
sqlstr VARCHAR2(4000);
....
sqlstr := my_pack.GETSQL( sql_id ... ); -- function

OPEN my_cursor FOR sqlstr;
...
END; If the length of sqlstr is > 4000,
 I get an exception and the error is: sqlstr _IS_NULL_ Why?
I'm using 8.1.7.0.3 on Linux.
