LIKE expressions are of the form: identifier [NOT] LIKE pattern-value [ESCAPE escape-character] where identifier has a String value; pattern-value is a string literal where '_' stands for any single character; '%' stands for any sequence of characters, including the empty sequence, and all other characters stand for themselves. The optional escape-character is a single-character string literal whose character is used to escape the special meaning of the '_' and '%' in pattern-value.
