Method Detail

writeStatement

public void writeStatement(String sql)

Description copied from interface: JdbcLogger

Writes the text of an SQL statement to the log.

Specified by:

writeStatement in interface JdbcLogger

Parameters:

sql - the SQL statement text to write

writeParameters

public void writeParameters(Parameter[] parameters)

Description copied from interface: JdbcLogger

Writes the parameters that will be bound for an SQL statement.

This method is invoked immediately after JdbcLogger.writeStatement(String) to log the actual parameter values that will be used to replace statement placeholders.

An implementation should check the configuration of the underlying log system as to whether this level of detail is enabled.

Specified by:

writeParameters in interface JdbcLogger

Parameters:

parameters - values that will be bound before statement execution
