Hi, May I get your help?
Table1
VoucherID       EntryID          Project      Expenses     Dept
123                   1                     A01           Travel          Null
123                   1                     Null          Null              Fin
Table2
VoucherID      EntryID      Amount
123                   1                100

How can I create a view as follows:
 VoucherID       EntryID    Amount  Project  Expenses Dept
123                     1               100         A01       Travel      Fin

Thanks

Here is the query,

select t1.voucherId,t1.EntryId,t1.Project,t3.Amount,t1.Expenses,t2.Dept from table1 as t1 
JOIN  table1 t2 on t1.voucherId = t2.voucherId
AND t1.EntryId = t2.EntryId
AND t1.Project=t2.Project
AND t1.Expenses IS NOT NULL AND t2.Dept IS NOT NULL
INNER JOIN Table2 t3 ON t2.voucherId=t3.VoucherId

like this

select t1.voucherId,t1.EntryId,t1.Project,t3.Amount,t1.Expenses,t2.Dept from table1 as t1 
JOIN  table1 t2 on t1.voucherId = t2.voucherId
AND t1.EntryId = t2.EntryId
AND t1.Expenses IS NOT NULL AND t2.Dept IS NOT NULL
INNER JOIN Table2 t3 ON t2.voucherId=t3.VoucherId

try this

select A.VoucherID, A.EntryID, Amount,  Project,  Expenses, Dept
from (select VoucherID, Max(EntryID) EntryID, Max(Project)Project, Max(Expenses) Expenses, Max(Dept) Dept
      from Table1
      group by VoucherID) A
left join (select VoucherID, MAX(EntryID) EntryID, MAX(Amount) Amount 
			from Table2
			group by VoucherID) B on A.VoucherID = B.VoucherID

It's hard to answer this without knowing more about what else might be in these fields and how else you might need to select data from them.

With just your three rows of sample data, a fairly simple "GROUP BY" query should work.

SELECT
  Table1.VoucherID, Table1.EntryID, Table2.Amount, Max(Table1.Project) AS Project, Max(Table1.Expenses) AS Expense, Max(Table1.Dept) As Dept
FROM
  Table1 INNER JOIN Table2 ON
    Table1.VoucherID = Table2.VoucherID AND
    Table1.EntryID = Table2.EntryID
GROUP BY
  Table1.VoucherID, Table1.EntryID, Table2.Amount

BUT THIS ASSUMES that there is never more than 1 record in Table1 where Project (or Expenses... or Dept) is not null.  That doesn't seem very realistic to me - but you know best.

What do you want to see if your Table1 data is more like this:

VoucherID       EntryID          Project      Expenses     Dept
123                   1                     A01           Travel          Null
123                   1                     Null          Null              Fin
123                   1                     Null          Meals           MIS

With my query the results would be Expenses = Travel and Dept = MIS.  Is that acceptable?

Since my way is also resulting the recordset you wanted and you wanted a VIEW right?... can you clarify of not considering mine? Thanks.
