PreparedQueryImpl

public PreparedQueryImpl(st.orm.core.template.PreparedQuery core)

Method Details

addBatch

public void addBatch(Data record)

Description copied from interface: PreparedQuery

Add a record to the batch.

Specified by:

addBatch in interface PreparedQuery

Parameters:

record - the record to add to the batch.

getGeneratedKeys

public <ID> Stream<ID> getGeneratedKeys(Class<ID> type)

Description copied from interface: PreparedQuery

Returns a stream of generated keys as the result of an insert statement. Returns an empty stream if the insert statement did not generate any keys.

The returned stream allows for lazy processing, meaning elements are generated only as they are consumed, optimizing resource usage. Note, however, that calling this method does trigger the execution of the underlying query, so it should only be invoked when the query is intended to run. Since the stream holds resources open while in use, it must be closed after usage to prevent resource leaks. As the stream is AutoCloseable, it is recommended to use it within a try-with-resources block.

Specified by:

getGeneratedKeys in interface PreparedQuery

Type Parameters:

ID - the type of generated keys

Parameters:

type - the class of the keys

Returns:

a stream of generated keys resulting from an insert statement; returns an empty stream if no keys are generated.

close

public void close()

Description copied from interface: PreparedQuery

Close the resources associated with this query.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface PreparedQuery
