The predefined stored procedure "GETALLCOMPANIES" returnes a result just like "select * from company" would. There are, however, procedures that do not return
results and these calls can also be executed with the same programming model. In fact any arbitrary stored procedure can be invoked in this way. The follwing example calls a proc that deletes an identified company:

Panel

DAS das = DAS.FACTORY.createDAS(getConnection());
Command delete = das.createCommand("
{call DELETECUSTOMER(question)(?)}
");
delete.setParameter(1, 1234);
delete.execute();

...

This example makes use of a configuration file to define the command including the OUT parameter:

No Format

<Config xsi:noNamespaceSchemaLocation="http:///org.apache.tuscany.das.rdb/config.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

...

   <Command name="getNamedCustomers" SQL="

...

{call GETNAMEDCUSTOMERS(?,?)}

...

" kind="procedure">

...



     <Parameter direction="IN" columnType="commonj.sdo.String"/>

...



     <Parameter direction="OUT" columnType="commonj.sdo.IntObject"/>

...



   </Command>

...



 </Config>

This stored procedure is defined such that the first argument provides a name to match when looking for customers and the second argument is an OUT parameter and providing the number of customers that match the provided name. The proc also returns the list of matching Customers.
