Custom Table

Hi Dear all:

I'm a abaper. I create a custom table with a field refer to sprsl. This field is one of keys. I maintain the table in SM30, I maintained two chars. I know sap internal mechanism convert the sprsl to language. But in SE38 my resport I 'select * from table' in the itab. I found here sap did not convert two chars to sprsl. How can I get that? Thanks.
