prepareQuery

public String prepareQuery(String query,
                           boolean allowNamedParameters,
                           org.apache.camel.Exchange exchange)
                    throws SQLException

Description copied from interface: SqlPrepareStatementStrategy

Prepares the query to be executed.

Specified by:

prepareQuery in interface SqlPrepareStatementStrategy

Parameters:

query - the query which may contain named query parameters

allowNamedParameters - whether named parameters is allowed

exchange - the current exchange

Returns:

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

Throws:

SQLException

createPopulateIterator

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

Description copied from interface: SqlPrepareStatementStrategy

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

Specified by:

createPopulateIterator in interface SqlPrepareStatementStrategy

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

Specified by:

populateStatement in interface SqlPrepareStatementStrategy

Parameters:

ps - the prepared statement

iterator - the iterator to use for getting the parameter data
