Remove last character from string in sql plus

问题

I'm trying to remove the last character from a column output in sql plus. The length of the column entries is not fixed

For e.g XYZA should output as XYZ

I've tried using the substr() function but it doesn't seem to work.

SUBSTR(ooo.CO_NAME,1,LENGTH(ooo.CO_NAME-1))

回答1:

A closing parenthesis is in the wrong place. It should be:

SUBSTR(ooo.CO_NAME, 1, LENGTH(ooo.CO_NAME) - 1)
