Hi,

I have a SQL query which will fetch the data in below format. Seq_NUM column is a dynamic column.I have to increment the seq number from one for every new FIELD1 value like below.

Is it possible to do it through SQL?
FIELD1	FIELD2	FIELD3	SEQ_NUM
-----------------------------------------------------------
AAA	name1	phone	1
AAA	name2	phone	2
AAA	name3	phone	3
AAA	name4	phone	4
BBB	name1	phone	1
BBB	name2	phone	2
CCC	name1	phone	1
CCC	name2	phone	2
CCC	name1	phone	3
CCC	name2	phone	4
CCC	name1	phone	5
CCC	name2	phone	6
