Answer Posted / parthasarathi
delete T1
from MyTable T1, MyTable T2
where T1.dupField = T2.dupField
and T1.uniqueField > T2.uniqueField ;
Try this will work for SQL Server and My Sql but not for
MSAccess .....
For MSAccess try the below one
delete from MyTable
where uniqueField not in
(select min(uniqueField) from MyTable T2
where T2.dupField=MyTable.dupField);
The above query also works for SqlServer but not for MySql..
