How to write update query to update two tables with SQL Data Source?
Is it possible to update two tables using SQL Data Source and ASP.NET Grid View? I have the following SQL Query for the Select statement.
SELECT
tbl_user_login.ID, tbl_user_login.UserID,
tbl_user_login.Pass, tbl_user_login.Enabled,
tbl_user_login.Permission, tbl_user_login.Rank,
tbl_user_profile.ID AS Expr1, tbl_user_profile.FName,
tbl_user_profile.LName, tbl_user_profile.Phone,
tbl_user_profile.Email1, tbl_user_profile.Email2
FROM
tbl_user_login
INNER JOIN
tbl_user_profile ON tbl_user_login.ID = tbl_user_profile.ID
But I've no idea how do I write the update and delete statement in SQL Data Source
UPDATE
So I wrote the store procedure.
CREATE PROCEDURE UpdateTwoTable
(
@ID int,
@UserID varchar(10),
@Pass varchar(50),
@Enabled int,
@Permission int,
@Rank int,
@FName varchar(50),
@LName varchar(50),
@Phone varchar(50),
@Email1 varchar(50),
@Email2 varchar(50)
) AS
BEGIN TRANSACTION
UPDATE tbl_user_login SET UserID = @UserID, Pass = @Pass, Enabled = @Enabled, Permission = @Permission, Rank = @Rank WHERE ID = @ID
IF @@ERROR <> 0
BEGIN
ROLLBACK
RETURN
END
UPDATE tbl_user_profile SET FName = @FName, LName = @LName开发者_JS百科, Phone = @Phone, Email1 = @Email1, Email2 = @Email2 WHERE ID = @ID
IF @@ERROR <> 0
BEGIN
ROLLBACK
RETURN
END
COMMIT
But I get the Procedure or function UpdateTwoTable has too many arguments specified.
UPDATE
I followed this guide and now the problem is solved. Thanks to everyone who helped!

Below is my SQL Data Source.
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:DBConnString %>"
SelectCommand="SELECT tbl_user_login.ID, tbl_user_login.UserID, tbl_user_login.Pass, tbl_user_login.Enabled, tbl_user_login.Permission, tbl_user_login.Rank, tbl_user_profile.ID AS Expr1, tbl_user_profile.FName,
tbl_user_profile.LName, tbl_user_profile.Phone, tbl_user_profile.Email1, tbl_user_profile.Email2 FROM tbl_user_login INNER JOIN tbl_user_profile ON tbl_user_login.ID = tbl_user_profile.ID"
UpdateCommand="UpdateTwoTable" UpdateCommandType="StoredProcedure"
OldValuesParameterFormatString="Original_{0}">
<UpdateParameters>
<asp:Parameter Name="ID" />
<asp:Parameter Name="UserID"/>
<asp:Parameter Name="Pass"/>
<asp:Parameter Name="Enabled"/>
<asp:Parameter Name="Permission"/>
<asp:Parameter Name="Rank"/>
<asp:Parameter Name="FName"/>
<asp:Parameter Name="LName"/>
<asp:Parameter Name="Phone"/>
<asp:Parameter Name="Email1"/>
<asp:Parameter Name="Email2"/>
</UpdateParameters>
</asp:SqlDataSource>
Yes, it's possible. Here is how to do it in a safe way:
CREATE PROCEDURE UpdateUser (@ID int, @Pass varchar(15), @Email varchar(75)) AS
BEGIN TRANSACTION
UPDATE tbl_user_login SET Pass = @Pass WHERE ID = @ID
IF @@ERROR <> 0
BEGIN
ROLLBACK
RETURN
END
UPDATE tbl_user_profile SET Email1 = @Email WHERE ID = @ID
IF @@ERROR <> 0
BEGIN
ROLLBACK
RETURN
END
COMMIT
In this way you don't need to be worried in case there is some error raised by any of the updates. Which means: If any of them will fail, the whole operation will be canceled and you will not have inconsistent data in your DB.

The basic DELETE statement is: DELETE FROM <tablename> WHERE <condition>
CREATE PROC UpdateUser
(
@ID int
,@Pass varchar(15)
,@Email varchar(75)
) AS
BEGIN
Update
tbl_user_login
Set
Pass = @Pass
Where
ID = @ID
Update
tbl_user_profile
Set
Email1 = @Email
Where
ID = @ID
END
You can write multiple sql commands into a single sproc as I have above. Expand updates as needed. Deletes work the same way...
<asp:SqlDataSource runat="server":
SelectCommand="SELECT ... "
UpdateCommand="UPDATE a; UPDATE b;"
DeleteCommand="DELETE FROM a; DELETE FROM b;" />
Doesn't it work?
