I have a table which has the following fields

Prefix
SheetNumber
WhatFor
ApprovalDate
FabricationDate

If I have two records which both have the same prefix and sheet number but have different WhatFor I only want to display 1 of the records.

Table
Prefix    SheetNumber      WhatFor           Approval Date   Fabrication Date
Ar            100                Approval                01/01/01           01/02/01
AR           100                Fabrication             01/01/01           01/02/01

Datagrid
Prefix      SheetNumber     Approval Date   Fabrication Date
AR               100                  01/01/01          01/02/01

Both records represent the same sheet which will have two records one for approval and one for fabrication, however for this particular datagrid I only need to display the record one time because they have the same dates and whatfor is irrelavent.

If you do not need field 'WhatFor' in datagrid, then you can write your query for retriving data like:

>>> "SELECT DISTINCT PREFIX, SheetNumber, ApprovalDate, FabricationDate FROM [TABLE]"

Use of distinct keyword will give you only 1 Record instead of 2.

Hi,
try this query,

SELECT DISTINCT Prefix, SheetNumber,  Approval Date,   Fabrication Date FROM <you table name> a, <you table name> b where a.Prefix = b.Prefis and a.SheetNumber = b.SheetNumber and a.WhatFor != b.WhatFor;

All the best.
