Question

I have a Table called “MIVTable” which has the following records,

    MIVID      Quantity         Value
   ------     ----------       --------
      14           10             3000
      14           20             3500
      14           15             2000
      15           20             3000
      15           50             7500
      16           25             2000

Here, I need to store the above Table into two tables such as “HeaderTbl” and “DetailTbl” based on the MIVID as follows:

HeaderTbl:

   HID      MIVID       TotalQuantity    TotalValue
  -----    -------      -------------    -----------
    1         14               45           8500 
    2         15               70          10500
    3         16               25           2000

Here HID is the Primary Key with Identity Column.

DetailTbl:

  HID        MIVID        Quantity        Value
 -----      -------     ------------     -------
   1           14             10           3000
   1           14             20           3500
   1           14             15           2000
   2           15             20           3000
   2           15             50           7500
   3           16             25           2000

Suppose, if the MIVTable contains 4 different MIVID means, then 4 row should be created based on the MIVID on the HeaderTbl. How to do this?

Answer 1

To insert records in HeaderTbl from MIVTable use this: (HID should be auto increment)

INSERT INTO HeaderTbl
    ([MIVID], [TotalQuantity], [TotalValue])
SELECT MIVID, SUM(Quantity), SUM(Value) FROM MIVTable GROUP BY MIVID;

To insert records in DetailTbl from HeaderTbl and MIVTable use this:

INSERT INTO DetailTbl
([HID], [MIVID], [Quantity], [Value])
    SELECT H.HID, M.* 
      FROM HeaderTbl H 
INNER JOIN MIVTable M
        ON H.MIVID = M.MIVID;

Look at this SQLFiddle

Here you need to use INSERT INTO SELECT statement to insert data from one table to another. You can also use JOIN in such statement as I did it for DetailTbl.
