Syntax:<br \> string_expression [NOT] LIKE pattern_value [ESCAPE escape_character] <br \> <br \> The string_expression must have a string value. The pattern_value is a string literal or a string-valued input parameter in which an underscore (_) stands for any single character, a percent (%) 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 or a character-valued input parameter (i.e., char or Character) and is used to escape the special meaning of the underscore and percent characters in pattern_value. <br \><br \> Examples: <br \> <ul> <li \>address.phone LIKE ‘12%3’ is true for '123' '12993' and false for '1234' <li \>asentence.word LIKE ‘l_se’ is true for ‘lose’ and false for 'loose' <li \>aword.underscored LIKE ‘\_%’ ESCAPE '\' is true for '_foo' and false for 'bar' <li \>address.phone NOT LIKE ‘12%3’ is false for '123' and '12993' and true for '1234' </ul> <br \> If the value of the string_expression or pattern_value is NULL or unknown, the value of the LIKE expression is unknown. If the escape_characteris specified and is NULL, the value of the LIKE expression is unknown.
