Hi Friends,

I have a following table say T1,

Amt. Type ( Type can have only R or E )
200 R
150 E
.........
.........

I have created another table, T2 on which there are 2 columns to hold the values from T1 based on Type field i.e if Type value = 'R' the corresponding Amt. value ( 200 ) should be inserted in to col1 in T2, similarly if Type value = 'E' its corresponding Amt. Value ( 150 ) should be inserted in to col2 in T2.

Need code to accomplish this ?

Thanx & Regards,
Prakash. K

What a big deal in that..?

You told that the table T1.TYPE can contain only R & E.

So just a simple query should serve your purpose.

INSERT INTO T2 SELECT * FROM T1.

if you think, there is no check constraint on T1.TYPE and contain others too. Then just filter it by WHERE predicate.

INSERT INTO T2 SELECT * FROM T1 where TYPE IN ('R','E')
