Hi All,

I have a flat file as follows:

ID,Name1,Name2,height1,height2
12,Test,X,12,13
13,Test2,Y,14,16

I need an sql loader control file that concatenates Name1 and Name2 into one db field and add up height1 and height 2 into one field so that I can get the following result in the following table:

ID, Name, Height
12, TestX, 25
13, Test2Y, 30

Thanks a lot for providing me with a CTL file example that can do that.

Regards,
Walid
