replace function in dml statements in oracle 8i

Can we use Replace() function in an update statement ? If yes then how?

I have a column enrollno having values like '800-00001' to '800-01800'. I want to replace initial '800-' to '800' in all 1800 records. (Output should be '8000001' to '80001800')

Is it possible through replace function or any other option is th开发者_如何转开发ere in ORACLE8i ?
