Maybe I don’t understand this correctly, but are you trying to use SQL Server’s ability to generate a result set from a stored proc call? If you, I would say you should probably use a select element rather than a statement element so that iBatis expects a result set. Otherwise, iBatis is probably expecting to return you the procedures return code or maybe the rows modified return from the database, I’m not sure.
From: Lee Shinlever [mailto:[EMAIL PROTECTED] Sent: Wednesday, September 12, 2007 4:27 PM To: [email protected] Subject: Return Results Greetings, Currently we are replacing all of the data access code in the ASP.Net Security Providers using Spring.Net and iBatis.Net. Basically instead of implementing a custom provider each time security persistence needs changed we just use one provider and change its data access component (iBatisNet) as needed. We did run into one operation that just won't return the expected results no matter what we do short of modifying the actual stored procedure. We don't have a problem changing the SPROC to make it work but we were wondering if anyone could point out what might be happening here. Components: 1) SQL Server 2005 2) Visual Studio 2005 3) iBatisNet DataMapper 1.6.1.0 Original Stored Procedure: ALTER PROCEDURE dbo.aspnet_Membership_GetNumberOfUsersOnline @ApplicationName nvarchar(256), @MinutesSinceLastInActive int, @CurrentTimeUtc datetime AS BEGIN DECLARE @DateActive datetime SELECT @DateActive = DATEADD(minute, -(@MinutesSinceLastInActive), @CurrentTimeUtc) DECLARE @NumOnLine int SELECT @NumOnLine = Count(*) FROM aspnet_Users AS u WITH (NOLOCK) INNER JOIN aspnet_Applications AS a WITH (NOLOCK) ON u.ApplicationId = a.ApplicationId INNER JOIN aspnet_Membership AS m WITH (NOLOCK) ON u.UserId = m.UserId WHERE (u.LastActivityDate > @DateActive) AND (a.LoweredApplicationName = LOWER(@ApplicationName)) return @NumOnLine END Statement: <procedure id="GetNumberOfUsersOnline" resultClass="int" parameterMap="GetNumberOfUsersOnline"> aspnet_Membership_GetNumberOfUsersOnline </procedure> Parameter Map: <parameterMap id="GetNumberOfUsersOnline" class="Hashtable"> <parameter property="ApplicationName" column="ApplicationName" dbType="string" size="256"/> <parameter property="MinutesSinceLastInActive" column="MinutesSinceLastInActive" dbType="int"/> <parameter property="CurrentTimeUtc" column="CurrentTimeUtc" dbType="DateTime"/> </parameterMap> DAO Code: ...snippet... Hashtable parms = new Hashtable(); parms.Add("ApplicationName", applicationname); parms.Add("MinutesSinceLastInactive", minutessincelastinactive); parms.Add("CurrentTimeUtc", currenttimeutc); int results = 0; results = (int) CustomMapper.Instance().QueryForObject("GetNumberOfUsersOnline", parms); return results; ...snippet... Testing: Using the same parameters, expected results = 2 ... 1) Removed the return @NumOnLine line 1) Ran the SPROC in the SQL debugger - SQL output results were fine 2) Ran the original DAO code using SQL command objects - SQL command results were fine 3) Ran our DAO code using iBatisNet - no results ever return 4) Change mapping file and DAO code to reflect using a Hashtable as the return class - iBatisNet did not return any results 5) Changed @DateActive to anything else (date value) - iBatisNet results were fine Thanks, Lee -------------------------------------------------------- Princeton Retirement Group, Inc - Important Terms This E-mail is not intended for distribution to, or use by, any person or entity in any location where such distribution or use would be contrary to law or regulation, or which would subject Princeton Retirement Group, Inc. or any affiliate to any registration requirement within such location.
