public void parse(DatabaseSchema schema, int granularity, boolean isCaseSensitive) throws java.sql.SQLException
AbstractRequest
DatabaseSchema
of the database
targeted by this request.
An exception is thrown when the parsing fails. Warning, this method does not check the validity of the request. In particular, invalid request could be parsed without throwing an exception. However, valid SQL request should never throw an exception.
