Method Detail

prepareQuery

String prepareQuery(String query,
                  boolean allowNamedParameters)
                    throws SQLException

Prepares the query to be executed.

Parameters:

query - the query which may contain named query parameters

allowNamedParameters - whether named parameters is allowed

Returns:

the query to actually use, which must be accepted by the JDBC driver.

Throws:

SQLException

createPopulateIterator

Iterator<?> createPopulateIterator(String query,
                                 String preparedQuery,
                                 int expectedParams,
                                 org.apache.camel.Exchange exchange,
                                 Object value)
                                   throws SQLException

Creates the iterator to use when setting query parameters on the prepared statement.

Parameters:

query - the original query which may contain named parameters

preparedQuery - the query to actually use, which must be accepted by the JDBC driver.

expectedParams - number of expected parameters

exchange - the current exchange

value - the message body that contains the data for the query parameters

Returns:

the iterator

Throws:

SQLException - is thrown if error creating the iterator

populateStatement

void populateStatement(PreparedStatement ps,
                     Iterator<?> iterator,
                     int expectedParams)
                       throws SQLException

Populates the query parameters on the prepared statement

Parameters:

ps - the prepared statement

iterator - the iterator to use for getting the parameter data

expectedParams - number of expected parameters

Throws:

SQLException - is thrown if error populating parameters
