Move row from one table to another?

Question

I have two tables with the same column definitions. I need to move (not copy) a row from one table to another. Before I go off and use INSERT INTO/DELETE (in a transaction

Answer 1

No, you are pretty much stuck with insert and delete wrapped inside a transaction

Answer 2

for SQL Server 2005 and up, try the OUTPUT Clause (Transact-SQL) clause:

DELETE OldTable
  OUTPUT DELETED.col1, DELETED.col2...
      INTO NewTable
  WHERE ID=...

Working example:

DECLARE @OldTable table(col1 int, col2    varchar(5), col3 char(5), col4     datetime)
DECLARE @NewTable table(col1 int, column2 varchar(5), col3 int    , col_date char(23), extravalue int, othervalue varchar(5))
INSERT @OldTable VALUES (1 , 'AAA' ,'A'  ,'1/1/2010'           )
INSERT @OldTable VALUES (2 , 'BBB' ,'12' ,'2010-02-02 10:11:22')
INSERT @OldTable VALUES (3 , 'CCC' ,null ,null                 )
INSERT @OldTable VALUES (4 , 'B'   ,'bb' ,'2010-03-02'         )

DELETE @OldTable
    OUTPUT DELETED.col1
          ,DELETED.col2
          ,CASE
               WHEN ISNUMERIC(DELETED.col3)=1 THEN DELETED.col3 
               ELSE NULL END
          ,DELETED.col4
          ,CONVERT(varchar(5),DELETED.col1)+'!!'
        INTO @NewTable (col1, column2, col3, col_date, othervalue)
    OUTPUT 'Rows Deleted: ', DELETED.* --this line returns a result set shown in the OUTPUT below
    WHERE col1 IN (2,4)

SELECT * FROM @NewTable

OUTPUT:

               col1        col2  col3  col4
-------------- ----------- ----- ----- -----------------------
Rows Deleted:  2           BBB   12    2010-02-02 10:11:22.000
Rows Deleted:  4           B     bb    2010-03-02 00:00:00.000

(2 row(s) affected)

col1        column2 col3        col_date                extravalue  othervalue
----------- ------- ----------- ----------------------- ----------- ----------
2           BBB     12          Feb  2 2010 10:11AM     NULL        2!!
4           B       NULL        Mar  2 2010 12:00AM     NULL        4!!

(2 row(s) affected)

Answer 3

You can try Insert into abc (a,b,c) select(a,b,c) from def

doing above so will insert column a, b,c of def into column a,b,c of abc. after inserting run a delete table, drop table or truncate whatever is your criteria.

sample is:

Begin
    Begin try

         Begin Transaction

               Insert into emp(name, department, salary)                    
                       Select empName,empDepartment,empSal from employees
                       Where  employees.empID = 211

               Truncate table employees

          End Transaction  

    End try

    Begin Catch

         if @@Error > 0
              Rollback Transaction

    End Catch

End

Answer 4

There is no such thing as a MOVE command in SQL. You'll have to first insert from table 1 to table 2 Then remove the copy from table 1.

Answer 5

INSERT dbo.newtable(
      name,
      department,
      Salary
) SELECT 
            name,
            FirstName,
            Lastname
      FROM    (
           DELETE dbo.oldtable
           OUTPUT
                   DELETED.name,
                   DELETED.department,
                   DELETED.Salary
           WHERE ID  IN ( 1001, 1003, 1005 )
      ) AS RowsToMove  

SELECT * FROM dbo.newtable
SELECT * FROM dbo.oldtable
