PL/SQL: dynamic query in clob string. How can i open a cursor?












1














I am using Oracle 10g and I have problems with Open for Query_string.



that query string is a dynamic query, it has more than 7000 charcaters.



how can I open a cursor with varchar2 (which in 10g only accepts max length of 4000)? At the moment I tried using CLOB instead of but open..for doesnt accept it.



In the header is declared: TYPE tref IS REF CURSOR;



DECLARE
SQL CLOB;
BEGIN
SQL := '...';

OPEN tref FOR SQL
END


the version 10g not accepted is:



DECLARE
SQL VARCHAR2(8000);
BEGIN
SQL := '...';

OPEN tref FOR SQL
END


Thx

  • Even in Oracle 10, a PL/SQL variable can hold up to 32767 bytes: Quote from the manual "The VARCHAR2 datatype takes a required parameter that specifies a maximum size up to 32767 bytes"

  • anyway calling from .net to the store procedure says me the error of max length. obviouslly using 12g is no problem.

Ok guys



I got the solution, when you have CLOB, you can use dbms_lob.substr...



OPEN p_ref FOR dbms_lob.substr( SQL, 32000, 1 );
