PL/SQL Problem

I am using Oracle 6 in Unisys 6000 unix machine. Now, I am writing the application that need to check the char field which is numeric or character.

char field is numeric ==> contains 0 - 9 and space char field is character ==> contains a-z, A-Z and space

Would you tell me how to code it in PL/SQL? Received on Sat May 25 1996 - 00:00:00 CEST
