Datatype Mismatch

Hi All,

I have data in a csv file where it consists like

Col

($0.004)

($0.01)

($0.003)

.

.

.

I need in target like

Col

0.004

0.01

0.003  

I used replace to eliminate $,(,), and I kept Numeric datatype(18,2) in target column. When am loading the data, 4,1,null.

What is the appropriate datatype for target i tried decimal datatype also.

Regards,

Venkat.
