Is there a way to loop thru looking for duplicated values in a table "column1" and look at the next row in column2 for a value and if the value equals BBB then delete the duplicate values.
column1 column2
AAA
AAA
-------------BBB
CCC
CCC
CCC
-------------BBB
column1 column2
AAA
AAA
-------------BBB
CCC
