Select querry for maximum value

[Former Member]

Hi,

I want to select fields A B C D from a database table TAB using some selection criteria from selection screen, but the greatest value of A has to be selected for all unique entries of B C and D. Please suggest an appropriate select querry.

PS: I cannot use SELECT and then DELETE ADJACENT DUPLICATES as it will effect performance in some cases.

Regards.

Try using aggregate function MAX with SELECT statement.

MAX Returns the greatest value in the column determined by the database field f for the selected lines. Specifying DISTINCT does not change the result. NULL values are ignored unless all values in a column are NULL values. In this case, the result is NULL .

Have a look at below link:

I hope it helps.
