Syntax

Argument	Rules	Description
type	Mandatory	sqlBatch
operand	Mandatory	the <sql> query document
configuration	Optional	optional configuration document
target	Mandatory Fragment OK	a result document

The sqlBatch accessor performs batched SQL operations on an RDBMS using a JDBC connection. The operations are provided in the operand as a canonical <batch> document containing one ore more <sql> elements (see example above). The result is a document providing the operation index and number of rows updated by the update.

Configuration

By default the configuration will be read from ffpcl:/etc/ConfigRDBMS.xml. The document provides a driver and connection URI (see example below). Alternatively,the configuration can be provided in an optional <configuration> argument - this may be either a URI to a config document or a literal configuration document.

<config>  <rdbms>
    <jdbcDriver>com.mysql.jdbc.Driver</jdbcDriver>
    <jdbcConnection> jdbc:mysql://localhost:port/mydatabase?user=myusername&password=mypassword </jdbcConnection>
  </rdbms>
</config>
