Oracle Stored Procedure Not Accepting Comma delimited values in database

Question

I have a stored procedure which does the following, declares variables and assigns values retrieved from a parameter temp_table database to each variable, then it reads column headings from a master table. Using the variables assigned to each parameter from the temp_table as a filter, the rows from the MASTER TABLE are finally output by the procedure. The stored procedure works fine when dealing with single value string values passed from the parameter temp_table.
The problem comes in when multiple values are selected and stored in the database parameter field as a comma separated string, eg. A045, A012
So, the strored procedure has been modified to use a function to split the string into separate values: 'A045' and 'A012'. So that: A045, A012 from the database will be returned to the stored procedure variable as *('A045', 'A012')* . When testing the stored procedure using the static values *('A045', 'A012')* , data is returned.
eg. EMPLOYEE_MASTER.CODE IN ('*A045*', '*A012*') will return results
However, when *('A045', 'A012')* is dynamically concatenated from the function and assigned to variable:
paramCode := split_str(paramCode) with paramCode eventually being passed: *('A045', 'A012')*
to become:
EMPLOYEE_MASTER.CODE IN (paramCode)
then NO DATA is returned.
I am stuck and don't know what the problem is. If anyone has any ideas, please feel free to help. I have included the Actual Stored Procedure below for a better understanding.

Answer 1

This seems to work for me:
define param="'ABC','XYZ'"; --- Set up a test in clause
--- Test data
with test as
(select 'ABC' fld from dual union all
select 'DEF' from dual union all
select 'PQR' from dual union all
select 'XYZ' from dual)
--- Query starts here.
select fld
from test,
       table (sys.ODCIVarchar2List (&param)) p
where fld = p.column_valueOr Using an actual "IN" clause:
define param="'ABC','XYZ'";
with test as
(select 'ABC' fld from dual union all
select 'DEF' from dual union all
select 'PQR' from dual union all
select 'XYZ' from dual
p as
(select column_value from table (sys.ODCIVarchar2List (&param))
select fld
from test
where fld in (select column_value from p)Edited by: AlanWms on Nov 4, 2009 9:08 AM
