I am not sure if it is right place to ask the question. I have a store procedure in which funcitons are called and several temp tables are created. When I use sql analyzer, it runs fast. But when I called it from asp.net app, it runs slow and it waits and waits to get data and insert into temp tables and return. Though I have used with (nolock), it still not imprvoed. Any suggestions? Thanks in advance.

Hello, I am very new to ASP.NET and SQL Server. I am a college student and just working on some project to self teaching myself them both. I am having a issue. I was wondering if anyone could help me. Ok, I am creating a web app that will help a company to help with inventory. The employee's have cretin equipment assign to them (more then one equipment can be assigned). I have a search by equipment and employee, to search by equipment the entire database even then equipment that isn't assigned with the employee's it shows only that employees and if they have any equipment. They can select a recorded to edit or see the details of the record. The problem i am having is that the Info page will not load right. I am redirected the Serial Number and EmployeeID to the info page. I got everything working except one thing. If a person has more then one equipment when i click on the select it redirect and only shows the first record not the one I selected. and when i change it, a employee that doesn't have equipment will not show up totally.
SELECT E.FirstName AS UserFirstName, E.LastName AS UserLastName, eqtype.Description AS UserEquipType, empeq.UserEquipID, E.EmployeeID, E.cwopa_id, eq.IPAddress, eq.Location, eq.DataLine3, eq.DataLine2, eq.Voice, eq.DataLine1, eq.FloorBox, eq.Comments, eq.SerialNo, eq.Model, eq.Brand, eq.TagNo, eq.PurchaseLease, eq.WarrantyExpDate, eq.PhoneType, eq.PhoneNum, eq.CellNumber, eq.DataNumber, eq.SIDNumber, eq.Carrier FROM dbo.EMPLOYEES AS E LEFT OUTER JOIN dbo.EMPLOYEES_EQUIP AS empeq ON empeq.EmployeeID = E.EmployeeID LEFT OUTER JOIN dbo.EQUIPMENT AS eq ON eq.EquipID = empeq.EquipID LEFT OUTER JOIN dbo.EQUIP_TYPE AS eqtype ON eqtype.EquipTypeID = eq.EquipTypeID WHERE E.EmployeeID = @EmployeeID and eq.SerialNo=@SerialNo EmployeeID and SerialNo are primary keys. I was thinking maybe create a store procedures, but I have no idea how to do it. I created this and no syntax error came up but it doesn't work CREATE PROCEDURE dbo.inventoryinfo AS DECLARE @EmployeeID int DECLARE @SerialNo varchar(50) IF( @SerialNo is NULL) SELECT E.FirstName AS UserFirstName, E.LastName AS UserLastName, eqtype.Description AS UserEquipType, empeq.UserEquipID, E.EmployeeID, E.cwopa_id, eq.IPAddress, eq.Location, eq.DataLine3, eq.DataLine2, eq.Voice, eq.DataLine1, eq.FloorBox, eq.Comments, eq.SerialNo, eq.Model, eq.Brand, eq.TagNo, eq.PurchaseLease, eq.WarrantyExpDate, eq.PhoneType, eq.PhoneNum, eq.CellNumber, eq.DataNumber, eq.SIDNumber, eq.Carrier FROM dbo.EMPLOYEES AS E LEFT OUTER JOIN dbo.EMPLOYEES_EQUIP AS empeq ON empeq.EmployeeID = E.EmployeeID LEFT OUTER JOIN dbo.EQUIPMENT AS eq ON eq.EquipID = empeq.EquipID LEFT OUTER JOIN dbo.EQUIP_TYPE AS eqtype ON eqtype.EquipTypeID = eq.EquipTypeID WHERE E.EmployeeID = @EmployeeID ELSE SELECT E.FirstName AS UserFirstName, E.LastName AS UserLastName, eqtype.Description AS UserEquipType, empeq.UserEquipID, E.EmployeeID, E.cwopa_id, eq.IPAddress, eq.Location, eq.DataLine3, eq.DataLine2, eq.Voice, eq.DataLine1, eq.FloorBox, eq.Comments, eq.SerialNo, eq.Model, eq.Brand, eq.TagNo, eq.PurchaseLease, eq.WarrantyExpDate, eq.PhoneType, eq.PhoneNum, eq.CellNumber, eq.DataNumber, eq.SIDNumber, eq.Carrier FROM dbo.EMPLOYEES AS E LEFT OUTER JOIN dbo.EMPLOYEES_EQUIP AS empeq ON empeq.EmployeeID = E.EmployeeID LEFT OUTER JOIN dbo.EQUIPMENT AS eq ON eq.EquipID = empeq.EquipID LEFT OUTER JOIN dbo.EQUIP_TYPE AS eqtype ON eqtype.EquipTypeID = eq.EquipTypeID WHERE E.EmployeeID = @EmployeeID and eq.SerialNo=@SerialNoGO Also, when a user selects the select button in either Employee search or Equipment search it redirects them to info.aspx. Should I create a different aspx page for both? But I don't believe I should do that. I don't know if I gave you enough information or not. But if you could give examples that would be wonderful! Thanks so much Nickie
