This example executes a CREATE statement against the target database to create a table and various column definitions.

<!-- Setting the input db item and attributes -->
<arc:set attr="db.driver" value="cdata.jdbc.mysql.MySQLDriver" />
<arc:set attr="db.conn" value="jdbc:cdata:mysql:server=localhost;port=3306;database=sakila;user=root;password=Password123;"/>
<arc:set attr="db.query" value="CREATE TABLE Neighbors (PersonID int,LastName varchar(255),FirstName varchar(255),Address varchar(255),City varchar(255));"/>

<!-- Calling the operation, passing in the db item and setting an output item -->
<arc:call op="dbNonQuery" in="db" out="results" >
  <!-- optional logging step to see the output attributes of the query in the application log -->
  <arc:set attr="_log.info" value="[results.*]" />
</arc:call>

This example executes a parameterized INSERT statement against the target table:

<!-- Setting the input db item and attributes -->
<arc:set attr="db.driver" value="cdata.jdbc.mysql.MySQLDriver" />
<arc:set attr="db.conn" value="jdbc:cdata:mysql:server=localhost;port=3306;database=sakila;user=root;password=Password123;"/>
<arc:set attr="db.query" value="INSERT INTO Neighbors (PersonID, LastName, FirstName, Address, City ) VALUES (@param1, @param2, @param3, @param4, @param5);"/>
<arc:set attr="db.paramname#1" value="param1" />
<arc:set attr="db.paramvalue#1" value="1" />
<arc:set attr="db.paramname#2" value="param2" />
<arc:set attr="db.paramvalue#2" value="Bobby" />
<arc:set attr="db.paramname#3" value="param3" />
<arc:set attr="db.paramvalue#3" value="Ricky" />
<arc:set attr="db.paramname#4" value="param4" />
<arc:set attr="db.paramvalue#4" value="26 Wonder Bread Lane" />
<arc:set attr="db.paramname#5" value="param4" />
<arc:set attr="db.paramvalue#5" value="Charlotte" />

<!-- Calling the operation, passing in the db item and setting an output item -->
<arc:call op="dbNonQuery" in="db" out="results" >
  <!-- optional logging step to see the output attributes of the query in the application log -->
  <arc:set attr="_log.info" value="[results.*]" />
