public class PreparedBatch
extends SqlStatement<PreparedBatch>
implements ResultBearing

Represents a prepared batch statement. Multiple bindings are added to the compiled statement and then executed in a single operation. This is, generally, a very efficient way to execute large numbers of the same statement where the statement only varies by the arguments bound to it. The statement starts with an empty binding. You bind a single batch of parameters with the usual SqlStatement binding methods, and then call add() to add the current binding as a batch and then clear it. An entire batch can be bound and added in one go with add(Map) or add(Object...).

Method Details

scanResultSet

public <R> R scanResultSet(ResultSetScanner<R> mapper)

Description copied from interface: ResultBearing

Specified by:

scanResultSet in interface ResultBearing

Type Parameters:

R - result type returned by the mapper.

Parameters:

mapper - result set scanner

Returns:

the value returned by the mapper.

execute

public int[] execute()

Execute the batch and return the number of rows affected for each batch part. Note that some database drivers might return special values like Statement.SUCCESS_NO_INFO or Statement.EXECUTE_FAILED.

Returns:

the number of rows affected per batch part

See Also:

• Statement.executeBatch()

executeAndGetModCount

public ResultIterator<Integer> executeAndGetModCount()
