Update a table from another table

Update t2
SET QtyOut = QtyOut + qty
FROM table2 t2 INNER JOIN Table1 t1 on t1.FromWarehouse     = t2.wareHouse

Update t2
SET QtyOut = QtyOut + qty
FROM table2 t2 INNER JOIN Table1 t1 on t1.ToWarehouse   = t2.wareHouse

UPDATE TableTwo
SET  OtyOut = Qty
FRom   TableTwo t INNER JOIN TableOne g
              ON t.Warehouse = g.FromWareHouse
UPDATE TableTwo
SET  OtyIn = Qty
FRom   TableTwo t INNER JOIN TableOne g
              ON t.Warehouse = g.ToWareHouse

Hope this helps.
Kindly specify the columns and details so that exact query can be given

udpate table2
set QtyIn = t1.
from table1 t1, table2 t2
where t2.Warehouse = t1.FromWarehouse

Hi All,

I am so sorry, I should mentioned Insert, not Update, since the rows of data could change.
Usually I delete the transaction first then insert it.

Please see my revised table.

TableOne  :

1. TrsId
2. FromWarehouse
3. ToWarehouse
4. ProductCode
5. Qty


TableTwo :

1. TrsId
2. Warehouse
3. ProductCode
4. QtyIn
5. QtyOut

Sample:

TableOne:

TrsId  FromWarehouse    ToWarehouse   ProductCode   Qty
001    A                             B                      CocaCola         10

TableTwo:

TrsId  Warehouse    ProductCode  QtyIn     QtyOut
001    A                     CocaCola       0             10
001    B                     CocaCola       10           0

Thank you.

<< How to update TableTwo using TableOne? >>
which column you want to update and with what value?

Hi Sharath_123,

Please see my last post Id 24786018

Thank you.

We both were posting at the same time, hence i missed your last post. so do you want to insert data into second table based on the data in the first table?

Hi Sharath_123,

Yes.

Hi pssandhu,


It needs two query to solve this. Correction, you miss the "From TableOne" clause.
Is there any other way to do it?

Thank you.

try this

insert into TableTwo
select TrsId,FromWarehouse as WareHouse,ProductCode,0 as QtyIn,Qty as QtyOut from TableOne
union all
select TrsId,FromWarehouse as WareHouse,ProductCode,Qty as QtyIn,0 as QtyOut from TableOne

Select allOpen in new window

Yes you can use the union clause to achive that as shown by sharath_123 above.

Hi pssandhu,

Yes, I prefer Sharath_123 method.

Thank you very much for your help.
