You can specify the character to be used to escape wildcard characters (% and _, for example) in LIKE clauses. The escape sequence for escape characters is:

{escape 'escape-character'}

where:

escape-character
is the character used to escape the wildcard character.

For example. the following SQL statement specifies that an asterisk (*) be used as the escape character in the LIKE clause for the wildcard character %:

SELECT col1 FROM table1 WHERE col1 LIKE '*%%' {escape '*'}

Note: The right-hand side of a LIKE expression must evaluate to a string or binary.
