<p>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:</p>

<pre><code>CREATE PROCEDURE getSomething @keyList varchar(4096)
AS
SELECT * FROM mytbl WHERE name IN (@keyList)
</code></pre>

<p>How do I call my stored proc with more than 1 value in the list?
So far I've tried </p>

<pre><code>exec getSomething 'John'         -- works but only 1 value
exec getSomething 'John','Tom'   -- doesn't work - expects two variables
exec getSomething "'John','Tom'" -- doesn't work - doesn't find anything
exec getSomething '"John","Tom"' -- doesn't work - doesn't find anything
exec getSomething '\'John\',\'Tom\'' -- doesn't work - syntax error
</code></pre>

<p><strong>EDIT:</strong> I actually found this <a href="http://vyaskn.tripod.com/passing_arrays_to_stored_procedures.htm" rel="noreferrer">page</a> that has a great reference of the various ways to pas an array to a sproc</p>

Do you need to use a comma separated list? The last couple of years, I've been taking this type of idea and passing in an XML file. The openxml "function" takes a string and makes it like xml and then if you create a temp table with the data, it is queryable.
```
```
DECLARE @idoc int
DECLARE @doc varchar(1000)
SET @doc ='
<ROOT>
<Customer CustomerID="VINET" ContactName="Paul Henriot">
   <Order CustomerID="VINET" EmployeeID="5" OrderDate="1996-07-04T00:00:00">
      <OrderDetail OrderID="10248" ProductID="11" Quantity="12"/>
      <OrderDetail OrderID="10248" ProductID="42" Quantity="10"/>
   </Order>
</Customer>
<Customer CustomerID="LILAS" ContactName="Carlos Gonzlez">
   <Order CustomerID="LILAS" EmployeeID="3" OrderDate="1996-08-16T00:00:00">
      <OrderDetail OrderID="10283" ProductID="72" Quantity="3"/>
   </Order>
</Customer>
</ROOT>'
--Create an internal representation of the XML document.
EXEC sp_xml_preparedocument @idoc OUTPUT, @doc
-- Execute a SELECT statement that uses the OPENXML rowset provider.
SELECT    *
FROM       OPENXML (@idoc, '/ROOT/Customer',1)
            WITH (CustomerID  varchar(10),
                  ContactName varchar(20))
```
```
