Ok guys, I have a developer that needs some help and for some reason I'm drawing a blank - perhaps because I'm not a VB .Net developer. They have a screen where a user can select multiple values (all numeric) and then they want to execute a stored procedure from .Net with an "IN" statement. So, here's what their variable is setup as: v_tid varchar2(5000); Then they're passing this in from .Net: 5000,5001,5002,5003 The code they're trying to execute in Oracle is: Select .... From .... Where trip_id in (v_tid); /* (where v_tid is the comma delimited string of numbers) */ This returns the ORA-01722 invalid number error. If I'm not mistaken this is because the value inside the () looks like ('5000,5001,5002,5003') which is no good. I tried wrapping the IN statement in a replace and replace tick marks with nothing but that still returns ORA-01722. Since I know this is something that gets done fairly regularly, how can they accomplish passing a comma delimited string into a procedure? The procedure will return a ref cursor of the results.
