Hi Experts,

How can we make a SP or UDF to accept variable number of paramters, same like we pass to SP_ExecuteSql and Coalesce()?

Thanks,
Imran

you can put optional parameters:

create proc <procname>
( @param1 int
, @param2 int = NULL
, @param3 int = NULL
)

Either,
pass the values as a delimited text, then do the separation inside the stored procedure using temporary table.

OR

the best way is to use XML. Send the parameters as a XML Document, then using OPENXML you can manipulate it.

call like

ProcName @param1 = 10, @param3 =10

well; those are internal procedures (developed in c).

I don't see what is wrong about the optional parameters, as some system stored procedure work the same way..

angelIII, there is nothing wrong with optional parameters except you need to know Max number of parameters and may be the data type too.

I was just looking for the way if could be done simply in t-sql.

I know what you want to get at, a PARAMARRAY parameter like in VB, giving to the procedure code an array of the values passed.
But, helas, no such thing in SQL. the closest thing is the XML parameter
