Get Identity of destination table when using **DELETE FROM ... OUTPUT ... INTO** - sql

Question

I use bellow code to archive old data in ArchiveTable and delete archived data from SourceTable
DELETE FROM SourceTable
OUTPUT
DELETED.[ID],
DELETED.[Code],
DELETED.[Title]
INTO ArchiveTable([OldID], [Code], [Title])
WHERE Condition
Structure of tables:
CREATE TABLE [SourceTable](
[ID] [INT] IDENTITY(1,1) NOT NULL,
[Code] [VARCHAR](16) NULL,
[Title] [NVARCHAR](128) NULL,
CONSTRAINT [PK_SourceTable] PRIMARY KEY CLUSTERED ([ID] ASC)
)
GO
CREATE TABLE [ArchiveTable](
[ID] [INT] IDENTITY(1,1) NOT NULL,
[OldID] [INT] NOT NULL,
[Code] [VARCHAR](16) NULL,
[Title] [NVARCHAR](128) NULL,
CONSTRAINT [PK_ArchiveTable] PRIMARY KEY CLUSTERED ([ID] ASC)
)
GO
I need to return deleted records and ArchiveTable.[ID] to application. I change the code like this:
DELETE FROM SourceTable
OUTPUT
DELETED.[ID],
DELETED.[Code],
DELETED.[Title]
INTO ArchiveTable([OldID], [Code], [Title])
OUTPUT DELETED.*
WHERE Condition
This code return deleted records but I don't know how to get ID of ArchiveTable for this records. Look at ArchiveTable structure, It has OldID column that refer to SourceTable.ID and ID column that it is an Identity column of ArchiveTable. I need to ArchiveTable.ID in final result.

Answer 1

You can use a temporary table
CREATE TABLE #DeletedRows(
[ID] [INT] NOT NULL,
[Code] [VARCHAR](16) NULL,
[Title] [NVARCHAR](128) NULL
)
DELETE SourceTable
OUTPUT
DELETED.[ID],
DELETED.[Code],
DELETED.[Title]
INTO #DeletedRows([ID], [Code], [Title])
WHERE Condition
INSERT ArchiveTable([OldID], [Code], [Title])
OUTPUT INSERTED.*
SELECT [ID], [Code], [Title]
FROM #DeletedRows
DROP TABLE #DeletedRows
A variant with a table variable
DECLARE #DeletedRows TABLE(
[ID] [INT] NOT NULL,
[Code] [VARCHAR](16) NULL,
[Title] [NVARCHAR](128) NULL
)
DELETE SourceTable
OUTPUT
DELETED.[ID],
DELETED.[Code],
DELETED.[Title]
INTO #DeletedRows([ID], [Code], [Title])
WHERE Condition
INSERT ArchiveTable([OldID], [Code], [Title])
OUTPUT INSERTED.*
SELECT [ID], [Code], [Title]
FROM #DeletedRows

I found an interesting variant using DML with OUTPUT in SP and INSERT...EXEC... after that:
Test tables:
CREATE TABLE TestTable(
ID int NOT NULL PRIMARY KEY,
Title varchar(10) NOT NULL
)
CREATE TABLE TestTableLog(
LogID int NOT NULL IDENTITY,
OperType char(1) NOT NULL,
CHECK(OperType IN('I','U','D')),
ID int NOT NULL,
Title varchar(10) NOT NULL
)
DML procedures:
CREATE PROC InsTestTable
#ID int,
#Title varchar(10)
AS
INSERT TestTable(ID,Title)
OUTPUT inserted.ID,inserted.Title,'I' OperType
VALUES(#ID,#Title)
GO
CREATE PROC UpdTestTable
#ID int,
#Title varchar(10)
AS
UPDATE TestTable
SET
Title=#Title
OUTPUT inserted.ID,inserted.Title,'U' OperType
WHERE ID=#ID
GO
CREATE PROC DelTestTable
#ID int
AS
DELETE TestTable
OUTPUT deleted.ID,deleted.Title,'D' OperType
WHERE ID=#ID
GO
Tests:
-- insert test
INSERT TestTableLog(ID,Title,OperType)
EXEC InsTestTable 1,'A'
INSERT TestTableLog(ID,Title,OperType)
EXEC InsTestTable 2,'B'
INSERT TestTableLog(ID,Title,OperType)
EXEC InsTestTable 3,'C'
-- update test
INSERT TestTableLog(ID,Title,OperType)
EXEC UpdTestTable 2,'BBB'
-- delete test
INSERT TestTableLog(ID,Title,OperType)
EXEC DelTestTable 3
GO
-- show resutls
SELECT *
FROM TestTableLog
Maybe it'll be interesting to someone.
