Error executing a Oracle query when connection is fetched from Datasource

Question

Hi Folks,
I am struggling with a rather wierd issue. The DBA of my application has exposed some function based view(not exactly sure what that means) which returns results like any query over a table. I am having a tough time consuming it in my java application. The name of the view is - `networknode_api.get_ftapp_networknode_hrchy` The SQL for it is(syntax might be a bit strange as there is actual word `table` in the query)
view plaincopy to clipboardprint?
Note: Text content in the code blocks is automatically word-wrapped
01.SELECT * FROM table (networknode_api.get_ftapp_networknode_hrchy('19-Feb-2013'));
SELECT * FROM table (networknode_api.get_ftapp_networknode_hrchy('19-Feb-2013'));
The query returns a hierarchical result data, provided below is a sample output (ignore the ouput if the formatting is too werid)
Parent_NODE | Child_NODE | NODE_DISPLAY_NAME | BEGIN_DATE | END_COB_DATE | LVL
null | CCN | Connent Node | 01/20/2013 | 10/19/2013 | 1
CCN | AVT | Avg Vol Turn | 01/20/2013 | 10/19/2013 | 2
AVT | L:2 | L:2 | 01/20/2013 | 10/19/2013 | 3
AVT | L:6 | L:6 | 01/20/2013 | 10/19/2013 | 3
CCN | NUT | Nap Up Turn | 01/20/2013 | 10/19/2013 | 2
I have the following method in my DAO -
public List<NetworkNodeGroupDTO> fetchNetworkNodeHierarchy(Date cobDate) {
try {
InitialContext ic = new InitialContext();
//DataSource ds1 = (DataSource) ic.lookup("jndiDsFlex");
//Connection conn = ds1.getConnection();
/* Using the RmiDataSource class for performance optimizations */
weblogic.jdbc.common.internal.RmiDataSource ds = (weblogic.jdbc.common.internal.RmiDataSource) ic.lookup("jndiDsNex");
Connection conn = ds.getConnection();
Statement stmt = conn.createStatement();
boolean hasRows = stmt.execute("SELECT * FROM table (networknode_api.get_ftapp_networknode_hrchy('19-Feb-2013'))");
rs = stmt.getResultSet();
while(rs.next()) {
System.out.println(rs.getString("parent_node"));
System.out.println(rs.getString("child_node"));
System.out.println(rs.getString("node_display_name"));
stmt.close(); stmt = null;
conn.close(); conn = null;
} catch(Exception ex) {
ex.printStackTrace();
return null; // please ignore the return type for now
Exception is thrown at line - stmt.execute(....)
java.sql.SQLSyntaxErrorException: ORA-00904: : invalid identifier
I debugged through the code and noted the driver and connection details that the connection object has embedded. Using that I wrote a sample java jdbc code-
public static void main(String[] args) throws Exception {
try {
//Class.forName("oracle.jdbc.driver.OracleDriver");
//Class.forName("weblogic.jdbc.rmi.Driver");
Driver myDriver = (Driver) Class.forName("weblogic.jdbc.jts.Driver").newInstance();
} catch (ClassNotFoundException e) {
System.out.println("Where is your Oracle JDBC Driver?");
e.printStackTrace();
return;
Connection connection = null;
try {
connection = DriverManager.getConnection(
"jdbc:oracle:thin:@//ssn20331020-rt.eu.prog.net:1522/NEXSERV",
"sample",
"sample1234");
} catch (SQLException e) {
System.out.println("Connection Failed! Check output console");
e.printStackTrace();
return;
Statement stmt = connection.createStatement();
stmt.execute("SELECT * FROM table (flex_compnode_api.get_ftapp_compnode_hrchy('19-Feb-2013'))");
ResultSet rs = stmt.getResultSet();
int i = 0;
while(rs.next()) {
String pNode = rs.getString("parent_node");
String cNode = rs.getString("child_node");
String dName = rs.getString("node_display_name");
System.out.println("Hello: "+i++);
The above code works perfectly fine. Also tried the above code using normal Oracle JDBC driver and too works fine. I am baffled; what goes wrong when using the connection from a DataSource object. Does the driver treat SQL statements differently based on how the connection object is obtained? Appreciate your inputs/comments for same.
The oracle db version is - Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
Application Server - Weblogic 10.3

Answer 1

Below is the stacktrace and the driver details which are same for both the standalone basic Jdbc program and one where connection is fetched through datasource.
Driver name: Oracle JDBC driver
Driver version : 11.2.0.2.0
Driver major ver: 11
Driver minor ver: 2
