to_number question 2004-07-15 - By Jonathan Gennick
Something is not right here. Stephen. Here is your query:
SLDC > select /*+ NO_MERGE(Z) NO_PUSH_PRED(Z) PUSH_SUBQ(Z) */ distinct
SLDC > nbr_cc_fop_name into v_fop from
SLDC > (select nbr_cc_fop_name, nbr_cc_fop_high, nbr_cc_fop_low
SLDC > from nbr_cc where nbr_cc_fop_name in ( 'AX ', 'MC ', 'VI ', 'DS ')) Z
SLDC > where to_number(trim(substr(p_corigid,1,20))) between
SLDC > to_number(trim(nbr_cc_no_low))
SLDC > and to_number(trim(nbr_cc_no_high));
How can this even work? Your outer WHERE clause references
columns that do not exist in the table returned by your
subequery.
I built an nbr_cc table and ran your query. Below are the
results I get:
SQL > select distinct nbr_cc_fop_name into v_fop
2 from ( select nbr_cc_fop_name, nbr_cc_fop_high, nbr_cc_fop_low
3 from nbr_cc
4 where nbr_cc_fop_name in ( 'AX ', 'MC ', 'VI ', 'DS ')) Z
5 where to_number(trim(substr(p_corigid,1,20))) between
6 to_number(trim(nbr_cc_no_low))
7 and to_number(trim(nbr_cc_no_high));
and to_number(trim(nbr_cc_no_high))
*
ERROR at line 7:
ORA-00904 (See ORA-00904.ora-code.com): "NBR_CC_NO_HIGH ": invalid identifier
While NBR_CC_NO_HIGH *does* exist in nbr_cc, it does not
exist in the table Z that is returned from the subquery.
What am I missing here? So far as I can tell, the above
query should not even execute for you.
SQL > describe nbr_cc
Name Null? Type
-- ---- ---- ---- ---- ---- ---- ---- --- -- ----- -- ---- ---- ---- --
NBR_CC_FOP_NAME VARCHAR2(2)
NBR_CC_FOP_HIGH VARCHAR2(10)
NBR_CC_FOP_LOW VARCHAR2(10)
P_CORIGID VARCHAR2(30)
NBR_CC_NO_LOW VARCHAR2(20)
NBR_CC_NO_HIGH VARCHAR2(20)
