My last response was sparse so I decided to let you know what I was
thinking... I'm guessing that the size of your v_update field is too
small to store the string you are building... For example...
SQL> Create Table Tim ( Col1 Varchar2(10));
Table created.
SQL> Insert Into Tim Values ('test');
1 row created.
SQL> Commit;
Commit complete.
SQL> Declare
2 v_update varchar2(20);
3 v_table varchar2(20) := 'tim';
4 Begin
5 v_update := 'update '||v_table||' set col1 = ''value'' where col1
= ''test''';
6 execute immediate v_update;
7 End;

Hello, I'm trying to write a procedure that includes dynamic sql (8.17). If I don't use the dynamic sql, the query runs fine. If I do, it fails with a numeric or value error (ORA-06512).
Can anyone see what I'm missing? This works: UPDATE resourcegroup SET lft = DECODE( (SIGN((lft/drop_left)-1) + SIGN((lft/drop_right)-1)), 0, lft-1, 2, lft-2, lft), rgt = DECODE( (SIGN((rgt/drop_left)-1) + SIGN((rgt/drop_right)-1)), 0, rgt-1, 2, rgt-2, lft) WHERE lft > drop_left;
This fails: v_update := 'UPDATE '|| in_tablename || 'SET lft = DECODE( (SIGN((lft/:1)-1) + SIGN((lft/:2)-1)), 0, lft-1, 2, lft-2, lft), '|| 'rgt = DECODE( (SIGN((rgt/:3)-1) + SIGN((rgt/:4)-1)), 0, rgt-1, 2, rgt-2, lft) ' || 'WHERE lft > :5';
EXECUTE IMMEDIATE v_update USING drop_left, drop_right, drop_left, drop_right, drop_left;
I'm just using the linewrap concantenation for use of readability for testing. It fails when it's all on one line as well.
Thanks. -Deanna
