How to pass a comma separated list to a stored procedure?

Question

So I have a Sybase stored proc that takes 1 parameter that\'s a comma separated list of strings and runs a query with in in an IN() clause:

CREATE PROCEDURE          


        

Answer 1

This works in SQL. Declare in your GetSomething procedure a variable of type XML as such:

DECLARE @NameArray XML = NULL

The body of the stored procedure implements the following:

SELECT * FROM MyTbl WHERE name IN (SELECT ParamValues.ID.value('.','VARCHAR(10)')
FROM @NameArray.nodes('id') AS ParamValues(ID))

From within the SQL code that calls the SP to declare and initialize the XML variable before calling the stored procedure:

DECLARE @NameArray XML

SET @NameArray = '<id>Name_1</id><id>Name_2</id><id>Name_3</id><id>Name_4</id>'

Using your example the call to the stored procedure would be:

EXEC GetSomething @NameArray

I have used this method before and it works fine. If you want a quick test, copy and paste the following code to a new query and execute:

DECLARE @IdArray XML

SET @IdArray = '<id>Name_1</id><id>Name_2</id><id>Name_3</id><id>Name_4</id>'

SELECT ParamValues.ID.value('.','VARCHAR(10)')
FROM @IdArray.nodes('id') AS ParamValues(ID)
