I am puzzled with a query.
I need find out the LAST row added in a table with a column with datatype Uniqueidentifier column is: aspnet_Applications.ApplicationId Notes: This column Uniqueidentifier it is NOT and IDENTITY Column.
I need also take the last row inserted and update it on a different table aspnet_Users.ApplicationId
I tried to use SCOPE_IDENTITY in MS SQL 2008 but does not work because SCOPE_IDENTITY is working only with IDENTITY column.
Here my code. Any ideas?
CREATE DATABASE Test;
GO
USE Test;
GO
-- Create entities
CREATE TABLE [dbo].[aspnet_Applications](
[ApplicationName] [nvarchar](256) NOT NULL,
[LoweredApplicationName] [nvarchar](256) NOT NULL,
[ApplicationId] [uniqueidentifier] NOT NULL,
[Description] [nvarchar](256) NULL,
PRIMARY KEY NONCLUSTERED
(
[ApplicationId] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY],
UNIQUE NONCLUSTERED
(
[LoweredApplicationName] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY],
UNIQUE NONCLUSTERED
(
[ApplicationName] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
ALTER TABLE [dbo].[aspnet_Applications] ADD DEFAULT (newid()) FOR [ApplicationId]
GO
CREATE TABLE [dbo].[aspnet_Users](
[ApplicationId] [uniqueidentifier] NOT NULL,
[UserId] [uniqueidentifier] NOT NULL,
[UserName] [nvarchar](256) NOT NULL,
[LoweredUserName] [nvarchar](256) NOT NULL,
[MobileAlias] [nvarchar](16) NULL,
[IsAnonymous] [bit] NOT NULL,
[LastActivityDate] [datetime] NOT NULL,

[UserId] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]

GO
ALTER TABLE [dbo].[aspnet_Users] WITH CHECK ADD FOREIGN KEY([ApplicationId])

GO
ALTER TABLE [dbo].[aspnet_Users] ADD DEFAULT (newid()) FOR [UserId]
GO
ALTER TABLE [dbo].[aspnet_Users] ADD DEFAULT (NULL) FOR [MobileAlias]
GO
ALTER TABLE [dbo].[aspnet_Users] ADD DEFAULT ((0)) FOR [IsAnonymous]
GO
-- Add data
DECLARE @MyIdentity binary(16);
INSERT INTO dbo.aspnet_Applications
(
ApplicationName,
LoweredApplicationName,
Description
)
VALUES
(
'x',
'x',
'Dummy text'
);
SET @MyIdentity = SCOPE_IDENTITY(); -- DOES NOT WORK
PRINT @MyIdentity; -- DOES NOT WORK
INSERT INTO dbo.aspnet_Users
(
ApplicationId,
UserName,
LoweredUserName,
MobileAlias,
IsAnonymous,
LastActivityDate
)
VALUES
(
@MyIdentity,
'Administrator',
'administrator',
'',
0,
sysutcdatetime()
);
It's a little more work, but for your inserts, even though you already have a DEFAULT value on the ApplicationID, you could do this:
DECLARE @MyIdentity uniqueidentifier;
SET @MyIdentity = NewID();
INSERT INTO dbo.aspnet_Applications
(
ApplicationName,
LoweredApplicationName,
ApplicationId,
Description
)
VALUES
(
'x',
'x',
@MyIdentity,
'Dummy text'
);
SELECT @MyIdentity
Essentially, you set the GUID beforehand, so you already know what you will be inserting.
You could use the OUTPUT
clause to get the inserted value(s) back but LBT's answer is probably more straightforward and efficient.
DECLARE @ids table(id uniqueidentifier)
INSERT INTO dbo.aspnet_Applications
(
ApplicationName,
LoweredApplicationName,
Description
)
OUTPUT INSERTED.ApplicationId into @ids
VALUES
(
'x',
'x',
'Dummy text'
)
By the way if it wasn't for the Foreign Key you could use composable DML for this as below.
INSERT
INTO dbo.aspnet_Users
(
ApplicationId ,
UserName ,
LoweredUserName,
MobileAlias ,
IsAnonymous ,
LastActivityDate
)
SELECT ApplicationId ,
'Administrator',
'administrator',
'' ,
0 ,
sysutcdatetime()
FROM ( INSERT
INTO dbo.aspnet_Applications
(
ApplicationName ,
LoweredApplicationName,
Description
)
OUTPUT INSERTED.ApplicationId VALUES
(
'x',
'x',
'Dummy text'
)
) AS I
