Passing array of parameters to UDF/Stored Proc in SQL Server

With the beautiful XML support from SQL Server 2005 onwards, passing multiple values to Stored Procedure or User Defined Function has never been so easy. Please see the sample code

-- Pass all employeeId or other information together
-- in a sincle call of the stored procedure

DECLARE @x xml, @EMPID INT
SELECT @x =
  N'<Root>
      <Employee empId="1"/>
    </Root>'
SELECT E.EMPLOYEEID FROM TBLEMP E   
JOIN @x.nodes('Root/Employee') AS T(Item)
ON E.EMPLOYEEID = T.Item.value('@empId', 'int')

-- Writting the stored procedure

CREATE PROCEDURE SP_EMPLOYEES @ids xml AS
   SELECT E.EMPLOYEEID, E.MANAGERID, E.NAME
   FROM   TBLEMP E
   JOIN   @ids.nodes('/Root/Employee') AS T(Item)
     ON   E.EMPLOYEEID = T.Item.value('@num', 'int')
go

-- Test the procedure with the following
EXEC SP_EMPLOYEES N'<Root><Employee num="1"/><Employee num="2"/>
                             <Employee num="3"/><Employee num="4"/></Root>'

Searching for a text on SQL Server (PL SQL Style)

Hi those coming from a PL SQL background will be knowing of a very common functionality which enables you to search for a particular text through PL SQL Dev tool on a particular text. Now if you try to look for a same type of a feature on SQL Server Management Studio, there is none.


The work around is the following stored procedure.
SELECT OBJECT_NAME(id)
FROM syscomments
WHERE [text] LIKE '%foobar%'
AND OBJECTPROPERTY(id, 'IsProcedure') = 1
GROUP BY OBJECT_NAME(id)

So if you want to search for a text like foobar in all procedures used in the database, the query would look like something above. If the same thing has to be searched in a function then the parameter "IsProcedure" has to be changed to "IsFunction".


This tip will particularly important if you are associated with support and enhancement kind of activity and need to find say "How many times a particular table name is used in a procedure or a function".

Introduction

Hi,

My name is Kaushik and I am an ASP.NET developer working in the Greater Chicago Area. I have created this blog so that I can refer to the resolutions that could gather or find out while doing my day to day activities. Nothing is impossible to implement through software and at the same time its not possible to know everything, so a good reference is a key to quick resolutions to complicated/simple tasks.
