Assuming you have a variable number of parameters (i.e. there may be more than just the three!) then the short answer is that it is possble and there are a number of ways to do it.

you COULD concatenate the string descriptions into a single comma separated string, pass that as a parameter and pass it to a stored procedure that returns a table with one row per Id

you COULD use a user-defined type in SQL Server, populate it in your application and pass it as a single parameter to a stored procedure, and again return the Ids

however, I wonder where you got the string s from - aren't they from teh database originally? if so, then when you retrieve the strings, retrieve their Ids too,and store them in your application, so no need to go retrieve them later
