UCASE or UPPER

UCASE or UPPER

UCASE or UPPER takes a character expression as a parameter and returns a string in which all alpha characters have been converted to uppercase.

Syntax

UCASE or UPPER ( CharacterExpression ) 

If the parameter type is CHAR , the return type is CHAR. Otherwise, the return type is VARCHAR.

Note:
UPPER and LOWER follow the database locale. See territory=ll_CC for more information about specifying locale.

The length and maximum length of the returned value are the same as the length and maximum length of the parameter.

Example

VALUES UPPER('aSD1#w')
