Re: Store big SQL(15000 char+) in the database.

Question

I have 2 very big SQL (almost 15000 char each). I have to store them in 2 saperate columns in a database table.
After storing them when ever require, sql will be retrieved and executed to get the values.
As varchar2 supports only 4000 chars. What would be the best data type to store big SQLs in the same table?
Thanks

Ooops, I misread original post. Somehow I read 15,000 as 150,000. MichaelS is right, PL/SQL VARCHAR2 is 32K-1 but is some cases it will work with up to 64K-1 (although not supported abd subject to change in next releases). Anyway, for up to 32,767 byte clobs:
SQL> declare c clob := to_clob('select ''') || lpad('X',4000,'X') || ''' from dual';
  2  begin
  3  execute immediate c;
  4  end;
  5  /
execute immediate c;
ERROR at line 3:
ORA-06550: line 3, column 19:
PLS-00382: expression is of wrong type
ORA-06550: line 3, column 1:

SQL> declare c clob := to_clob('select ''') || lpad('X',4000,'X') || ''' from dual';

  5  /
