Multiple Resultset

I tried to get multiple result sets in query by using sql query string like this, for example:
"select * from A; select * from B"
But I got oracl error: ORA-00911: Invalid character.
I thought we can do multiple result sets. Does anyone know correct way?
Thanks

if i have a bunch of simple select sql, doing multiple
resultset can reduce the trafficI'm not real big on sql, but it sounds to me like you need a stored procedure. Just a thought. I realize not all databases allow them.

Calling stored procedure and returning multiple resultsets

Hello,
Is it possible to create a procedure that return multiple result sets?
e.g.
procedure GetDataFromTables() is
begin
select * from table_one;
select * from table_two;
end GetDataFromTables;
And I want to call this procedure that returns multiple resultsets (one for table_one and another for table_two)
I have referred to the OCCI sample occiproc.cpp, but I am not sure how to handle multiple resultsets.
Your help is highly appreciated.

Thank You,
Got the REF cursor in storedproc.cpp.
But as it is documented, getCursor() gets the REF CURSOR value of an OUT parameter as a ResultSet.
So, is it true that if I have to write a procedure that selects * from 50 tables (50 SQL statements) , I have to set 50 OUT parameters to get the result sets.?
Is there any better way of doing this?
e.g. in DB2, we can open multiple cursors in the procedure body and then get the result set one after another.
CREATE PROCEDURE get_staging_data ()
RESULT SETS 1 <no. of result sets>
LANGUAGE SQL
BEGIN ATOMIC
DECLARE L_SQL varchar(5000);
DECLARE c CURSOR WITH RETURN TO CLIENT FOR L_STMT;
SET L_SQL = '';
SET L_SQL = 'SELECT * FROM ';
SET L_SQL = L_SQL || IN_Tab_Name ;
SET L_SQL = L_SQL || ' WHERE VERIFY_FLAG=''S'' FOR READ ONLY OPTIMIZE FOR 2000 ROWS' ;
PREPARE L_STMT FROM L_SQL;
OPEN c; < can open multiple cursors in the prodedure body>
END

Multiple ResultSets with Oracle Thin Driver.

Hi,
I am using Oracle Thin Driver to Connect to the Oracle Database (8.1.7). I wanted to take advantage
of the multiple Resultsets Scenario for fetching Data from the DB. Please have a look at the code
fragment below.
String sql = "select * from TAB1; select * from TAB2";
Connection conn = getConnection();
PreparedStatement stmnt = conn.prepareStatement(sql);
stmnt.execute();
However , I am getting the following Error.
java.sql.SQLException: ORA-00911: invalid character
Could anyone give me the possible reason/corrected syntax for the SQL.
Thanks for any help in advance.

It's unclear what your problem is...
However...
Oracle will only execute one SQL statement at a time in a Statement or PreparedStatement; therefore these can only return a single ResultSet.
However, an Oracle stored procedure can be written to return multiple results; it can therefore be run from a CallableStatement and getMoreResults() is then used to get the additional ResultSet data.
An example of doing this is here:
http://edocs.beasys.com/wls/docs81/jdbc_drivers/oracle.html
scroll towards the bottom and look for Listing 5-3

JDBC Adapter - Multiple Resultsets

Hello,
Does anyone know if the JDBC adapter can return multiple resultsets?
So something like the following JDBC Code:
CallableStatement cstmt;
ResultSet rs;
int i;
String s;
cstmt.execute();       //Call the stored procedure
rs = cstmt.getResultSet(); //Get the first resultset
while (rs.next()) {
i = rs.getInt(1);                          System.out.println("Value from first set = " + i);
cstmt.getMoreResults();//Point to the second resultset rs = cstmt.getResultSet();// Get the second resultset
while (rs.next()) {
s = rs.getString(1);
System.out.println("Value from second resultset = " + s);
Greetings,
Bart

Hi Bart,
sure you can select more than one table either with Stored Procedue or with Query Statement for example (also if you concate more than one SQL statement) like:
update table1 set STATUS = 4 where STATUS = 3 select *
from table1 bk inner join table2 on (KEY = BZ_KEY) where KEY = 449070
- or you create an View onb DB side that makes all of your Data selection:
select * from view where status = 4
- but you also can use stored procedure - in my opinion the most powerfuel tool...
If their is something left -keep asking
Regards Matt

Multiple resultset - strange problem

Hi,
I have a stored procedure that returns a single resultset correctly.
ResultSet rs = cstmt.executeQuery();
while(rs.next()).......
Now, I have to change this stored proc, to return multiple resultsets. To test if my code works, I did not change the stored proc(it still returns 1 resultset), but changed my code to -
boolean results = cstmt.execute();
System.out.print("do resultsets exist - "+results);
System.out.print("update count- "+cstmt.getUpdateCount());
For some strange reason, the boolean value is false! And the updatecount value is 1.
Can someone pls. explain this? I have the code for retrieving multiple resultsets, but it does not get executed because the initial 'results' value is false.
Thanks in advance.

I've never done what you're doing. I do it like this:
        CallableStatement cs = conn.prepareCall("{call PKG_BLAH.MY_FUNCTION(?,?,?)}");
        cs.setLong(1, someKey);
        cs.setString(2, someId's);
        cs.registerOutParameter(3, ORACLECURSORVALUE);
        cs.execute();
        ResultSet rs = (ResultSet) cs.getObject(3);
        while (rs.next()) {
}

Having multiple resultsets open at the same time

Hi,
I have the following piece of code to populate multiple resultsets returned by a call to a stored procedure in Sybase.
int l_noOfResultSetsReturned = 0;
int l_nextResultSetToPopulate = 1;
boolean l_isResultSet = l_CallableStatement.execute();
        while( l_isResultSet )
            switch ( l_nextResultSetToPopulate )
                case 1:
                    l_reportListResultSet = l_CallableStatement.getResultSet();
                    break;
                case 2:
                    l_inputSetterResultSet = l_CallableStatement.getResultSet();
                    break;
                case 3:
                    l_outputGetterResultSet = l_CallableStatement.getResultSet();
                    break;
                case 4:
                    l_outputColumnHeaderResultSet = l_CallableStatement.getResultSet();
                    break;
                default:
                    //throw new CubeInvalidNumberOfResultSetsException();
                    System.out.println(" More than 4 RS returned");
            l_noOfResultSetsReturned++;
            l_nextResultSetToPopulate++;
            l_isResultSet = l_CallableStatement.getMoreResults(PreparedStatement.KEEP_CURRENT_RESULT);
        }The problem is that when I try to run this, I get the following error:
java.lang.AbstractMethodError: com.sybase.jdbc.SybCallableStatement.getMoreResults(I)Z
I am using NetBeans 3.6 as the IDE with the java version 1.4.2_06. I got this error when I tried using jconnect45.jar for the driver part. I also tried the same with jconn2.jar. It also gave me the same error.
I need someway to ensure that the four resultsets are open for further down the line processing. Any help would be most welcome.
Thanks and regards,
Ganesh

I think the AbstractMethod Error is caused by calling a method which is not available on your JDBC Driver. This means you are using a JDBC 3 method on a JDBC 2 driver (or JDBC 2 on JDBC 1 driver). Check the JDBC version of your driver and use only the methods allowed for the JDBC driver version you have (or get a newer one).
Good Luck!

How to return Multiple ResultSets Using Callable Statement

hi everybody,
while i was working with callable statements i came across a problem of how to fetch Multiple Resultsets by means of Stored Procedures written for tables in Oracle.
If any one can help me, pls do help me with a detailed explanation, and if possible do get me a example source code too.
khumaar

I have a similar problem with oracle and jdbc:
I want to send a sql query like:
sqlQuery = "select n1, n2 from table1; select n1, n2
from table2"
I used a prepared statement, but when I call
.execute(sqlQuery)
oracle doesn't like this,
can someone help on this?Try putting a begin/end around it. Play with the syntax first in sqlplus.
You do realize that you MUST extract using the syntax for extracting multiple result sets correct? It will NOT work as one result set.

3You can observe that the code within while(rs.next()) is not getting executed. When I print rs.next() it is printed "false".
the store procedure is returning multiple result set values.
Any suggestions or help i can expect for???
thanks so much
Rk.

Try setting rs to null after each loop.As i
faced the same problem with ms access and it
worked.Hopefully it helps you out.You wrote a stored procedure in MS AccessMS-SQL Server, nobody said anything about Access.Okay never mind I misread your post and I have no clue what Ashitosh is on about.

Multiple ResultSets from the same connection occuring at the same time

Is it possible to have the following code? The issue is that you are iterating through two result sets created from the same connection at the same time.
try {
Connection conn=createConnection();
Statement s=conn.createStatement();
ResultSet rs=s.executeQuery(someSQL);
while (rs.next()) {
     Statement s2=conn.createStatement();
      ResultSet rs2=s2.executeQuery(someOtherSQL);
      while (rs2.next()) {
           //do something
} catch (SQLException sqle) {
} finally {
freeConnection(conn);

Joel,
The code compiles, but I have not tried running it. It is a question I need to know, designing a program.
The question is whether some error would come up or the first ResultSet would be corrupted because a second were created before the first one was closed.

Cannot read multiple resultsets from transaction datasource

I get a SQL exception "This object was closed() and cannot be used anymore."
when I try to access the first row of the second result set from a stored procedure.
This occurs when the code is running within an EJB using a transaction-capable
datasource hooked to a connection pool that uses the MSSQLSERVERv7 JDriver
to talk to SQL Server 7.0.
I noted that the resultset class used is weblogic.jdbc20.rmi.SerialResultSet.
The error occurs during the resultSet.next() call even though the resultset is
not null and getUpdateCount() returns -1.
However, the same code works correctly when run in a simple main() procedure from
the DOS command line, connecting directly to the database using only the classes
supplied with the JDriver product. The resultset class used in this case is
weblogic.jdbc.mssqlserver4.TdsResultSet.
The stored procedure is very simple, it just has two lines: SELECT 'Hello' and
SELECT 'World'. The Java code follows.
<PRE>
// ... code to get the connection ...
CallableStatement callableStatement = connection.prepareCall("{CALL spTest}");
callableStatement.execute();
ResultSet resultSet = callableStatement.getResultSet();
if ((resultSet != null) && resultSet.next())
System.out.println("Row from first result set:" + resultSet.getString(1));
callableStatement.getMoreResults();
resultSet = callableStatement.getResultSet();
if ((resultSet != null) && resultSet.next()) // this call to next() throws the
exception
System.out.println("Row from second result set:" + resultSet.getString(1));
resultSet.close();
callableStatement.close();
connection.close();
</PRE>

(multiple) ResultSet problem

I'm quite new to Java, but I couldn't find the answer to my question anywhere.
1. It's an applet
2. I'm using a MS Access 2000 ODBC/JDBC database
3. Everything seems to work. I can connect, I can see the database entry if using the first ResultSet ("SELECT * FROM PARKEERGARAGE WHERE DATUM ='" + datum + "';"). But my 2nd resultset doesn't work. ( else { if (x == 5 || x == 6 || x == 7 || x == 1 || x == 2) { ......... )
4. This is only a small part of a huge applet.
This is what I want:
1. Check if the string is in the database (if yes, show it... that works)
2. If it isn't, calculate (using GregorianCalendar) if it it is a Week or Weekend. (this doesn't work)
3. Whatever it is, retrieve the row with Date = Week or Weekend.
public void zoekOpeningstijden() {
GregorianCalendar calendar;
calendar = new GregorianCalendar(2004,12,30);
int i = 0;
String datum = beh_textfield_openingstijden_datum.getText();
int x = calendar.get(calendar.DAY_OF_WEEK);
connect();
try {
ResultSet rs = dbDAS.executeQuery("SELECT * FROM PARKEERGARAGE WHERE DATUM ='" + datum + "';");
while (rs.next()) {
i++;
if (i == 1) {
rs.previous();
panel_beh_openingstijden_textarea.setText(rs.getString("DATUM"));
rs.close();
else {
if (x == 5 || x == 6 || x == 7 || x == 1 || x == 2) {
rs = dbDAS.executeQuery("SELECT * FROM PARKEERGARAGE WHERE DATUM = 'Week';");
System.out.println(x);
System.out.println(rs.getString("DATUM"));
panel_beh_openingstijden_textarea.setText(rs.getString("DATUM"));
rs.close();
} else if (x == 3 || x == 4) {
rs = dbDAS.executeQuery("SELECT * FROM PARKEERGARAGE WHERE DATUM = 'Weekend';");
panel_beh_openingstijden_textarea.setText(rs.getString("DATUM"));
rs.close();
} catch (IOException ex) {} catch (SQLException ex) {}
close();
}

You are not correctly using the ResultSet.
1) In the case where i ==1, calling rs.previous() returns the cursor before the first record. Remove the rs.previous() call.
2) The general use of a ResultSet is:
   ResultSet rs = connection.executeXXXX("SELECT ...");
   while (rs.next()) {
      // At each iteration of the loop, the cursor is positionned on the next record
      // so, here you will read the fields and do your stuff with them
      // For example:
      String productCode = rs.getString(1); // first field of current record
      int productQty = rs.getInt(2);         // second field of current record
      double productPrice = rs.getDouble(3); // third field of current record
   }3) Concerning the date problem, read more carefully the API Javadoc for the GregorianCalendar constructor:
public GregorianCalendar(int year, int month, int date)
Constructs a GregorianCalendar with the given date set in the default time zone with the default locale.
Parameters:
year - the value used to set the YEAR time field in the calendar.
month - the value used to set the MONTH time field in the calendar. Month value is 0-based. e.g., 0 for January.
date - the value used to set the DATE time field in the calendar.
So, for DECEMBER you should use 11 instead of 12.
Hope this helped,
regards.

Multiple resultsets from the same query?

Hi all,
Can I define a query that will show more than one resultset (of similar structure), based on the different values of a particular characteristic?
Say, characteristic C1 has 3 different values x1, x2 and x3. Is it possible to output 3 different resulsets based on x1, x2 and x3?
Thanks,
Satyajit.

Hi Satyajit,
I hope i am getting your problem right.
By saying "3 different resulsets based on x1, x2 and x3"
did u mean to say that the list of key figures u have specified in your columns portion of your query should be displayed 3 times,First with x1, then with x2 and then x3.?
If thats the case what u can do is drag the characteristic C1 into the columns section of your query designer and keep it in top , followed by the key figures.
Then you can achieve the desired result..
Hope it helps.
Regards,
Parth.

Unable to Return multiple ResultSet

Can someone please tell me why the following code doesn't work?
It sets each String to the query return, but not every subsequent return.
In other words, it sets it the first time, and that's it. It appears to continue
continue looping for each of the following query returns, but never sets the
Strings to those other values.
calls_change_pstmt.execute();
            /* Retrieving results */
            ResultSet rs = calls_change_pstmt.getResultSet();
            while(rs.next() ) {
                beat = rs.getString("BEAT");
                call_descr = rs.getString("CALL_DESCR");
                priority = rs.getString("PRIORITY");
                date = rs.getString("DATE");
                time = rs.getString("TIME");
                location = rs.getString("LOCATION");
                status = rs.getString("STATUS");
                System.out.print(beat);
            }

You'll have to excuse me, but I don't understand your answers. I've posted a more detailed example of my code:
calls_change_pstmt = conn.prepareStatement
                    ("SELECT BEAT,CALL_DESCR,PRIORITY,DATE,TIME,LOCATION," +
                    "STATUS FROM SWEATY_BALLSAK.CALLS WHERE CALL_NUM = ?");
     * Detects a change between
     * the stored call and this call
     * @param call a String array
     * @return true if this call matches a stored call; false otherwise
    private boolean calls_change(String call[] ) {
        boolean change_found = false;
        boolean more_results = false;

            System.exit(0);
            return change_found;
    }I've taken out my logic to find a duplicate, and inserted a System.out.println instead. For clarity. Each of the Strings gets the correct value, the problem is each return after the first. How would I create more resultsets if I have no idea beforehand how many results i'm going to get? In this particular example it is suppose to return 3 sets, but at some point it could possibly be many many more.

Multiple Field field search with multiple resultset

I have 10 controls in a form and when a control is selected the rest of controls are re-populated
Here's my table structure
Field1
Field2
Field3
Field4
Field5
Field6
Field7
Field8
Field9
Field10
Bus
Tyre
Steering
Engine
Gear
Fuel
MultiSeat

Each field is dependent on other field. By default DISTINCT rows in each field is returned as a result set as below:
select distinct(field1) from table
select distinct(field2) from table
Upon selecting any of the item from the dropdown rest of the dropdowns are bound.
Is there any simplistic approach available?

Hi
Try this
Create a
datraview for above table in .net
Then use
ToTable() method of datagridview which return datatable
to get distinct value pass true in
toTable() method which return distinct row set for column specified in toTable method
Mark as answer if you find it useful

HELP: SSIS 2012 - Execute SQL Task with resultset to populate user variables produces DBNull error

I am experiencing an unexplainable behavior with the Execute SQL Task control in SSIS 2012. The following is a description of how to simulate
the issue I will attempt to describe:
1. Create a package and add two variables User::varTest1 and User::varTest2 both of String type with default value of "Select GetDate()"
for each, have shown this to not matter as the same behavior occurs when using a fixed string value or empty string value.
2. Add a new Execute SQL Task to the control flow.
3. Configure an OLE DB connection.
4. Set SQLSourceType = "Direct Input"
5. Set the ResultSet property of the task to "Single Row"
6. In the ResultSet tab add two results as follows:
Result Name: returnvalue1, Variable Name: User::varTest1
Result Name: returnvalue2, Variable Name: User::varTest2
7. Set an expression for the SqlStatementSource property with a string value of "Select 'Test' returnvalue1, 'Testing' returnvalue2'"
The idea is that the source would be dynamically set in order to run a t-sql statement which would have dynamic values for database name
or object that would be created at runtime and then executed to set the user variable values from its resultset. Instead what occurs is that a DBNull error occurs.
I am not sure if anyone else has experienced this behavior performing similiar actions with the Execute SQL Task or not. Any help would be
appreciated. The exact message is as follows:
[Execute SQL Task] Error: An error occurred while assigning a value to variable "varRestoreScript": "The type of the value
(DBNull) being assigned to variable "User::varRestoreScript" differs from the current variable type (String). Variables may not change type during execution. Variable types are strict, except for variables of type Object.
User::varRestoreScript is the first return value. And even with the a dummy select the same result occurs. I have narrowed the issue down
to the T-SQL Statement structure itself.
The following works just fine within the execute sql task control as long as no resultset is configured for return:
"Declare @dynamicSQL nvarchar(max)
Select @dynamicSQL = name
From sys.databases
Where name = 'master'
Select atest_var1=@dynamicSQL, atest_var2='static'"
I have tried various iterations of the script above with no success. However, if I use the following derivative of it the task completes
successfully and variables are set as expected. This will not work for my scenario however as I need to dynamically build a string spanning multiple resultsets to build one of the variable values.
"Select atest_var1=name, atest_var2='static'
From sys.databases
Where name = 'master'
I have a sample package which can reproduce this issue using the above code. You can get to that through the post on www.sqlservercentral.com/Forums/Topic1582670-364-1.aspx

Arthur, the query when executed doesn't return a null value for the @dynamicSQL variable. It returns "master" as a string value. Even the following fails which implements that suggestion:
Declare @dynamicSQL as nvarchar(max)
Select @dynamicSQL = name
From master.sys.databases
Where name = 'master' -- (or any other DB name)
I believe I have found the cause of the issue. It is datatype and size related. The above script will properly set the variables in the resultset as long as you don't use nvarchar(max) or varchar(max). This makes the maximum data size for
a String variable 4000 characters whether unicode or non-unicode typed.
