Hello,
I have FM_TEST_CUSTOMER.xml:
<Config xsi:noNamespaceSchemaLocation="
http:///org.apache.tuscany.das.rdb/config.xsd"; xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance";>
<Command name="all customers" SQL="select USER_ID,USER_NAME,PASSWORD from
FM_TEST_CUSTOMER WHERE USER_ID=2" kind="Select"/>
<Table tableName="FM_TEST_CUSTOMER" >
<Column columnName="USER_ID" primaryKey="true" />
<Column columnName="USER_NAME"/>
<Column columnName="PASSWORD"/>
</Table>
<Table tableName="FM_TEST_ORDER" >
<Column columnName="ORDER_ID" primaryKey="true" />
<Column columnName="GOOD_ID"/>
<Column columnName="PRICE"/>
<Column columnName="AMOUNT"/>
<Column columnName="USER_ID" />
</Table>
<Relationship name="users" primaryKeyTable="FM_TEST_CUSTOMER"
foreignKeyTable="FM_TEST_ORDER" many="true">
<KeyPair primaryKeyColumn="USER_ID" foreignKeyColumn="USER_ID"/>
</Relationship>
</Config>
And my java code:
DAS das = DAS.FACTORY.createDAS(test.getConfig("FM_TEST_CUSTOMER.xml"),
getConnection());
Command selectCommand = das.getCommand("all customers");
DataObject root = selectCommand.executeQuery();
DataObject FM_TEST_CUSTOMER = (DataObject) root.getDataObject
("FM_TEST_CUSTOMER[1]");
When I run this code,The program throws a exception:
Exception in thread "main"
org.eclipse.emf.common.util.BasicEList$BasicIndexOutOfBoundsException:index=0,
size=0
