Use SUBSTR to extract the first 6 digits and then convert it back to number using TONUMBER. If you specify only trimsource, Oracle removes leading and trailing blank spaces. Since whitespace is difficult to see in browser output, I’ll use the strlen ( ) function and provide the length of an example string, that is prefixed with a single space character, before and after using trim ( ) on the string variable: The TRUNC function is one of the most common and versatile functions in Oracle.
