All Implemented Interfaces:

Closeable, AutoCloseable, Configurable<PreparedBatch>, ResultBearing

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...).

Constructors

Constructor	Description
PreparedBatch(Handle handle, CharSequence sql)
PreparedBatch(Handle handle, String sql)	Backwards compatible constructor that takes an explicit string argument.

Method Summary

Modifier and Type	Method	Description
PreparedBatch	add()	Add the current binding as a saved batch and clear the binding.
PreparedBatch	add(Object... args)	Bind arguments positionally, add the binding as a saved batch, and then clear the current binding.
PreparedBatch	add(Map<String,?> args)	Bind arguments from a Map, add the binding as a saved batch, then clear the current binding.
final PreparedBatch	attachToHandleForCleanup()	Registers with the handle for cleaning when the handle is closed.
void	close()
final boolean	equals(Object o)
int[]	execute()	Execute the batch and return the number of rows affected for each batch part.
<R> R	execute(ResultProducer<R> producer)	Executes the batch, returning the result obtained from the given ResultProducer.
ResultIterator<Integer>	executeAndGetModCount()	Execute the batch and return the mod counts as in execute, but as a Jdbi result iterator instead of an array.
ResultBearing	executeAndReturnGeneratedKeys(String... columnNames)	Deprecated. Use executePreparedBatch(String...) which has the same functionality but also returns the per-batch modified row counts.
BatchResultBearing	executePreparedBatch(String... columnNames)	Execute the batch and give access to any generated keys returned by the operation.
ConfigRegistry	getConfig()	Returns the configuration registry associated with this object.
final StatementContext	getContext()	Returns the statement context associated with this statement.
final Handle	getHandle()
final int	hashCode()
<R> R	scanResultSet(ResultSetScanner<R> resultSetScanner)	Invokes the mapper with a result set supplier, and returns the value returned by the mapper.
int	size()	Returns the number of bindings in this batch.

PreparedBatch

public PreparedBatch(Handle handle,
 CharSequence sql)

PreparedBatch

public PreparedBatch(Handle handle,
 String sql)

Backwards compatible constructor that takes an explicit string argument.

See Also:

• PreparedBatch(Handle, CharSequence)

Method Details

scanResultSet

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

Description copied from interface: ResultBearing

Invokes the mapper with a result set supplier, and returns the value returned by the mapper.

Specified by:

scanResultSet in interface ResultBearing

Type Parameters:

R - result type returned by the mapper.

Parameters:

resultSetScanner - 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()

Execute the batch and return the mod counts as in execute, but as a Jdbi result iterator instead of an array.

Returns:

the number of rows affected per batch part

See Also:

• execute()
• Statement.executeBatch()

executeAndReturnGeneratedKeys

@Deprecated
public ResultBearing executeAndReturnGeneratedKeys(String... columnNames)

Deprecated.

Use executePreparedBatch(String...) which has the same functionality but also returns the per-batch modified row counts.

Execute the batch and give access to any generated keys returned by the operation.

Parameters:

columnNames - The column names for generated keys.

Returns:

A ResultBearing object that can be used to access the results of the batch.

executePreparedBatch

public BatchResultBearing executePreparedBatch(String... columnNames)

Execute the batch and give access to any generated keys returned by the operation.

Parameters:

columnNames - The column names for generated keys.

Returns:

A BatchResultBearing object that can be used to access the results of the batch and the per-batch modified row counts.

execute

public <R> R execute(ResultProducer<R> producer)

Executes the batch, returning the result obtained from the given ResultProducer.

Type Parameters:

R - the type of the result

Parameters:

producer - the result producer.

Returns:

value returned by the result producer.

add

public PreparedBatch add()

Add the current binding as a saved batch and clear the binding.

Returns:

this

add

public PreparedBatch add(Object... args)

Bind arguments positionally, add the binding as a saved batch, and then clear the current binding.

Parameters:

args - the positional arguments to bind

Returns:

this

add

public PreparedBatch add(Map<String,?> args)

Bind arguments from a Map, add the binding as a saved batch, then clear the current binding.

Parameters:

args - map to bind arguments from for named parameters on the statement

Returns:

this

size

public int size()

Returns the number of bindings in this batch.

Returns:

the number of bindings in this batch.

getHandle

public final Handle getHandle()

getConfig

public ConfigRegistry getConfig()

Description copied from interface: Configurable

Returns the configuration registry associated with this object.

Specified by:

getConfig in interface Configurable<This>

Returns:

the configuration registry associated with this object.

getContext

public final StatementContext getContext()

Returns the statement context associated with this statement.

Returns:

the statement context associated with this statement.

attachToHandleForCleanup

@Beta
public final PreparedBatch attachToHandleForCleanup()

Registers with the handle for cleaning when the handle is closed.
There are some situations where Statements need to be cleaned up to avoid resource leaks. This method registers the current Statement it with the Handle. If the statement or the context are cleaned by themselves, it will automatically unregister, so in normal operations, resources should not pool for cleanup with the Handle.

Since:

3.35.0

close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

equals

public final boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public final int hashCode()

Overrides:

hashCode in class Object
