In Oracle/PLSQL, the upper function converts all letters in the specified string to uppercase. If there are characters in the string that are not letters, they are unaffected by this function.
The syntax for the upper function is:
upper( string1 )
string1 is the string to convert to uppercase.
Applies To:
- Oracle 8i, Oracle 9i, Oracle 10g, Oracle 11g
For example:
upper('24x7 information for you'); | would return '24X7 INFORMATION FOR YOU' |
