Method Details

getEscapeChar
public char getEscapeChar()This method will return an escape character for the like clause. The escape character will eventually end up in the query as
...(t0.foo LIKE ? {escape '|'})
where the pipe symbol is the escape character.Note that having no escape character is represented as the character 0.
-
setEscapeChar
public void setEscapeChar(char value)This method allows the setting of the escape character. The escape character can be used in a LIKE clause. The character 0 signifies no escape character. The escape character '?' is disallowed.
