        Builds the PS part for a WhereClauseExpression with a LIKE operator. Multicharacter wildcards % and * may be used as well as single character wildcards, _ and ?. These characters can be escaped with \. e.g. criteria = "fre%" -> columnName LIKE 'fre%' -> UPPER(columnName) LIKE UPPER('fre%') criteria = "50\%" -> columnName = '50%'
        Parameters:
        whereClausePart - the part of the where clause to build. Can be modified in this method.
        ignoreCase - If true and columns represent Strings, the appropriate function defined for the database will be used to ignore differences in case.
        query - the query which is currently built
        adapter - The adapter for the database for which the SQL should be created, not null.
        Returns:
        the rendered SQL for the WhereClauseExpression
        Throws:
