setBlobAsBytes

public void setBlobAsBytes(PreparedStatement ps,
 int paramIndex,
 @Nullable
 byte[] content)
                    throws SQLException

Description copied from interface: LobCreator

Set the given content as bytes on the given statement, using the given parameter index. Might simply invoke PreparedStatement.setBytes or create a Blob instance for it, depending on the database and driver.

Specified by:

setBlobAsBytes in interface LobCreator

Parameters:

ps - the PreparedStatement to the set the content on

paramIndex - the parameter index to use

content - the content as byte array, or null for SQL NULL

Throws:

SQLException - if thrown by JDBC methods

See Also:

• PreparedStatement.setBytes(int, byte[])

setBlobAsBinaryStream

public void setBlobAsBinaryStream(PreparedStatement ps,
 int paramIndex,
 @Nullable
 InputStream binaryStream,
 int contentLength)
                           throws SQLException

Description copied from interface: LobCreator

Set the given content as binary stream on the given statement, using the given parameter index. Might simply invoke PreparedStatement.setBinaryStream or create a Blob instance for it, depending on the database and driver.

Specified by:

setBlobAsBinaryStream in interface LobCreator

Parameters:

ps - the PreparedStatement to the set the content on

paramIndex - the parameter index to use

binaryStream - the content as binary stream, or null for SQL NULL

Throws:

SQLException - if thrown by JDBC methods

See Also:

• PreparedStatement.setBinaryStream(int, java.io.InputStream, int)

setClobAsString

public void setClobAsString(PreparedStatement ps,
 int paramIndex,
 @Nullable
 String content)
                     throws SQLException

Description copied from interface: LobCreator

Set the given content as String on the given statement, using the given parameter index. Might simply invoke PreparedStatement.setString or create a Clob instance for it, depending on the database and driver.

Specified by:

setClobAsString in interface LobCreator

Parameters:

ps - the PreparedStatement to the set the content on

paramIndex - the parameter index to use

content - the content as String, or null for SQL NULL

Throws:

SQLException - if thrown by JDBC methods

                              throws SQLException

Description copied from interface: LobCreator

Set the given content as character stream on the given statement, using the given parameter index. Might simply invoke PreparedStatement.setCharacterStream or create a Clob instance for it, depending on the database and driver.

Specified by:

setClobAsCharacterStream in interface LobCreator

Parameters:

ps - the PreparedStatement to the set the content on

paramIndex - the parameter index to use

characterStream - the content as character stream, or null for SQL NULL

Throws:

See Also:

• PreparedStatement.setCharacterStream(int, java.io.Reader, int)

close

public void close()

Description copied from interface: LobCreator

Close this LobCreator session and free its temporarily created BLOBs and CLOBs. Will not need to do anything if using PreparedStatement's standard methods, but might be necessary to free database resources if using proprietary means.

NOTE: Needs to be invoked after the involved PreparedStatements have been executed or the affected O/R mapping sessions have been flushed. Otherwise, the database resources for the temporary BLOBs might stay allocated.
