Invalid Number Using 'IN' Clause

Question

Hi,
I use the following select statement to populate a report.
<p>
SELECT cpnidd, ...
FROM pdrcpn, pdrcpnsts
WHERE pdrcpnsts.cpnref1=pdrcpn.cpnref
AND pdrcpn.bizidd1 IN (SELECT PKG_APEX.GetUserBizIds(:APP_USER) from dual)
<p>
In the <b>IN</b> clause I use a call to a function to return a list of comma seperated numbers. This only works if a single number is returned, if more than one number is returned (eg. 23,34) I get the following error:
<p>
report error:
ORA-01722: invalid number
<p>
Am stumped as to why this is happening or how I can fix it, any help would be greatly appreciated.
<p>
Cheers
<p>

'bizidd1' is a number so SQL is expecting a list of numbers separated by comas. What '(SELECT PKG_APEX.GetUserBizIds(:APP_USER) from dual)' returns is one text string. So if it returns '1,2,3,4' your SELECT will execute the following:
SELECT cpnidd, ...
  FROM pdrcpn, pdrcpnsts
WHERE pdrcpnsts.cpnref1=pdrcpn.cpnref
  AND pdrcpn.bizidd1 IN <B>'1,2,3,4'</B>Where what you want to execute is really:
SELECT cpnidd, ...
  FROM pdrcpn, pdrcpnsts
WHERE pdrcpnsts.cpnref1=pdrcpn.cpnref
  AND pdrcpn.bizidd1 IN <B>(1,2,3,4)</B>So how to get it to work. Whatever table PKG_APEX.GetUserBizIds retrieves it values from (say YOUR_TABLE) change your SELECT to be something like:
SELECT cpnidd, ...
  FROM pdrcpn, pdrcpnsts
WHERE pdrcpnsts.cpnref1=pdrcpn.cpnref
  AND pdrcpn.bizidd1 IN <B>(SELECT your_column FROM your_table WHERE id = :APP_USER)</B>If you are using the SELECT statement for a report region, you could change your region to a PL/SQL function that returns the SELECT statement like:
DECLARE
  v_sql VARCHAR2(4000);  -- bad to hardcode limits
BEGIN
  v_sql := 'SELECT cpnidd, ... '||
           '  FROM pdrcpn, pdrcpnsts '||
           ' WHERE pdrcpnsts.cpnref1=pdrcpn.cpnref '||
           '  AND pdrcpn.bizidd1 IN ('||
           REPLACE (PKG_APEX.GetUserBizIds(:APP_USER)||' )';
  RETURN(v_sql);
END;in a PL/SQL variable and
