Aqui está o método Java simples de fazer isso:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import oracle.jdbc.OracleCallableStatement;
public class TestDatabaseArray
{
public static void main( final String[] args )
{
try{
Class.forName( "oracle.jdbc.OracleDriver" );
Connection con = DriverManager.getConnection(
"jdbc:oracle:thin:@localhost:1521:orcl",
"username",
"password"
);
OracleCallableStatement st
=(OracleCallableStatement) con.prepareCall("{ call get_names( :out_array ) }");
st.registerOutParameter( 1, java.sql.Types.ARRAY, "NAMELIST" );
st.execute();
String[] names = (String[]) st.getARRAY( 1 ).getArray();
for ( final String name : names )
System.out.println( name );
}
catch ( ClassNotFoundException | SQLException ex )
{
System.out.println( ex.getMessage() );
ex.printStackTrace();
}
}
}
