Try to add space before SET (if in_tablename doesn't end with the
space):
v_update := 'UPDATE '|| in_tablename ||
' SET lft = DECODE( (SIGN((lft/:1)-1) + SIGN((lft/:2)-1)),
0,
lft-1, 2, lft-2, lft), '||
and so on...

Subject: Dynamic SQL question
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.
