Method Detail

parse

public static void parse(String sqlString,
                         ParameterParser.Recognizer recognizer)
                  throws QueryException

Performs the actual parsing and tokenizing of the query string making appropriate callbacks to the given recognizer upon recognition of the various tokens.

Note that currently, this only knows how to deal with a single output parameter (for callable statements). If we later add support for multiple output params, this, obviously, needs to change.

Parameters:

sqlString - The string to be parsed/tokenized.

recognizer - The thing which handles recognition events.

Throws:

QueryException - Indicates unexpected parameter conditions.

startsWithEscapeCallTemplate

public static boolean startsWithEscapeCallTemplate(String sqlString)

Exposed as public solely for use from tests

Parameters:

sqlString - The SQL string to check

Returns:

true/false
