If neither pattern_expression nor expression has been designated CASESPECIFIC, any lowercase letters in pattern_expression and expression are converted to uppercase before the comparison operation occurs. If ESCAPE is specified and the escape character is a lowercase character, it is also converted to uppercase before the comparison operation occurs.

If either expression or pattern_expression has been designated CASESPECIFIC, two letters match only if they are the same letters and the same case.
