string_expression [NOT] LIKE pattern_value [ESCAPE escape_character]

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.

<li \>address.phone LIKE <EFBFBD>12%3<EFBFBD> is true for '123' '12993' and false for '1234'
|
|||
|
|
<li \>asentence.word LIKE <EFBFBD>l_se<EFBFBD> is true for <EFBFBD>lose<EFBFBD> and false for 'loose'
|
|||
|
|
<li \>aword.underscored LIKE <EFBFBD>\_%<EFBFBD> ESCAPE '\' is true for '_foo' and false for 'bar'
|
|||
|
|
<li \>address.phone NOT LIKE <EFBFBD>12%3<EFBFBD> is false for '123' and '12993' and true for '1234'

</ul>
