LIKE

USAGE

string LIKE match
string LIKE match ESCAPE escape_char

Value Name

Description

string

The string to search

match

The wildcard pattern used to search

escape_char

The escape character to use to disable wildcard characters

DETAILS

The LIKE operator matches a wildcard match string against a text string.

A 1 (true) is returned for a match, otherwise a 0 (false) is returned.

The characters % and _ are treated as wildcard characters unless they are escaped:

  • % (percent) - matches a string of any length, including nothing

  • _ (underscore) - matches any single character

  • \\ (backslash) - the default escape character

    • Ensures that the following character in the match string is treated as a normal character that must be matched

    • Can be changed to another character using the optional ESCAPE character clause

    • When using backslash as the escape character, it must often be doubled-up in order to be parsed as a single backslash

    • Keep in mind that a new escape character does not change the parsing of the string itself, so it cannot be used to try to escape a string's quoting character
