SSIS query returns no results - same query in SQL management studio works

Hello,
I'm running a very simple join to get a result set:
SELECT dbo.sap_contracts.svc_id, dbo.sap_contracts.svc_code, dbo.sap_contracts.quantity, dbo.sap_contracts.start_date, dbo.sap_contracts.end_date
FROM dbo.sap_contracts
INNER JOIN dbo.contracts
ON dbo.contracts.contract_id=dbo.sap_contracts.contract_id
where customer_name='XXXXXXXXX'
When I run this in SQL management studio it works fine and returns the list of existing "SAP contracts" in the DB (to compare to the customer's contracts actually in SAP).
In SSIS (SQL 2012) I'm using an Execute SQL task to run this query and putting the full results set into a variable of type "object". I've done very similar things before and it worked fine. With this query in SSIS I get no results at all. Changing
the variable type to "string" throws an error showing that the type being written to the variable is "DBNull" - so it seems that the query in SSIS returns no records, when in SQL management studio I get the 15 records that should be returned.
Does anyone have any ideas of what could be wrong?
Cheers
Mark

There are several connections to the DB in tasks before this one, and the task after this is a whole load of C# in a script task doing SOAP communications to the SAP ERP system to compare the result set from this SQL with the contracts in SAP ERP for the
specific customer.
Input variables are all correct (I've checked them about 15 times now with breakpoints on just about every task in the whole package) and I'm at the point of having to test everything in an attempt to see exactly what query is being sent to the SQL server
and anything else I can do to see why nothing comes back. There is a almost complete lack of debugging tools in SSIS which doesn't make life any easier (something I've heard quite a few times in various forums).
I'm tearing my hair out on this for half a day now and it's not funny any more, so apologies if I come across as a little frustrated.
Cheers

SQL query generating data in SQL management studio but not in CUIC interface

Hello,
I'm working on a UCCE 9.0 system
I created SQL query for a report.
Whenever I run the query inside the SQL management studio, it works and generates data, but when I run it in the CUIC interface it works but generates nothing. As you can see in the below snapshot, it contains 209 records that are not being displayed.
Any help would be greatly apprciated

Is it a custom report ? Can you right click on your Custom Report and click on Edit Views. You need to check whether you have Grid Headers Listed.

How do I load an SSIS package created in Visual Studio 2012 Shell (Integrated) onto SQL Server 2012 using SQL Management Studio 2012

I am fairly new to this whole process of working with the Microsoft development environment. Here is what I have to work with:
an NT server running Microsoft SQL 2012 - Microsoft SQL Server Standard (64-bit) 11.0.2100.60
and on my laptop (all freebie downloads):
SQL Server Management Studio 2012 ver 11.0.2100.60
Visual Studio 2012 Express for Desktop Development and
Visual Studio 2012 Shell (Integrated)
I was able to create an SSIS package in
2012 Shell (Integrated). It takes a flat file and imports it into an SQL database table. It runs successfully from within the
2012 Shell (Integrated) envrionment.
But I am having trouble figuring out how to set this up on the 2012 SQL Server. I see that one of my colleagues created an Integration Services Catalog,
and using SQL Management Studio I was able to create a folder under that called DigLic. But when I go to the Projects subfolder of DigLic and attempt to import my SSIS package, I get an error message:
"To launch the Integration Services Deployment wizard, one of the components: Integration Services, Management Tools - Basic or Business Intelligence Development Studio has to be installed by the SQL Server
2012 Standard, Enterprise, Developer, or Evaluation Edition. To install a component, run SQL Server Setup and Select the component name"
I realize that Express Versions of Visual Studio lack the full feature set of a professional version. But am I wrong in assuming that owning a server version of SQL Server 2012 gives us license to a professional
version of SQL Management Studio 2012? If so, how would I go about getting this software component installed? And I am not clear if this is something that needs to be installed on our SQL Server or if I simply need a professional version of SSMS
loaded on my laptop.
I work for a company that is fairly fractured in its repsonsibilities, so I would need to know exactly what to ask for if I need to track down any licenses that I might need and if I need to have any specific software installed on our SQL server or on my
laptop.
All helpt would be greatly appreciated.
Thanks!

Arthur,
Thank you for your reply. But at this point, one of my points of confusion is what software I have available to me. I wish I had a useful central help desk to call up and just say, "Hey, load me up with all of the professional version(s) of Visual
Studio. But I do not know what we have license to. And I kind of need to know what the options are, so that I can ask a specific question of our vast buracracy.
For now, I have downloaded only free versions of Visual Studio client software. Since my company does have servers running Microsoft SQL Server, I am going to assume that we have proper licensing for those servers. But does that server license
allow me to get any professional versions of the PC client software for the various Visual Studio(s) 2012?
And if I get a professional version of Visual Studio 2012, does that do away with the three different flavors that I have right now? I have 2012 versions of SQL Server Management Studio, Visual Studio Express, and Visual Studio Shell (Integrated).
Your feedback is much appreciated.
Thanks!

Xquery does not return any results on 10.2.0.4, does work on 10.2.0.5

I have a Xquery statement that works as expected on Oracle 10.2.0.5 but does not return any results on Oracle 10.2.0.4.
Is this the result of a badly written query? A bug in 10.2.0.4?
Is there a way to rewrite the query so that is does work on 10.2.0.4?

This one's strange indeed.
I can reproduce on 10.2.0.4 and one of the following seems to fix it :
1) Specifying the column list in the SELECT, instead of t.* :
   -- Select layers with TileMatrixSet EPSG:28992
   cursor c_layer(p_xml xmltype) is
      select t.title, t.format, t.style
        from xmltable(or,
2) Using an extended FLWOR expression :
for $d in //Layer
where $d/TileMatrixSetLink/TileMatrixSet = "EPSG:28992"
return $dMaybe you've already noticed but the problem only occurs within a PL/SQL context.
The same query run from SQL is OK.

Query editing in Management Studio

I've accidentally done something to my install of Management Studio that is making query editing very difficult. I must have used a weird key combination to enable some feature that is now opening an Intellisense like window with suggested keywords
or column names. I've tried every option I can find to disable this and even tried all the <ctrl> key combinations from A-Z to try to turn this off. Can anyone tell me how to have the editor revert to the "default" behavior as installed?
I've received several replies about disabling Intellisense or changing the Intellisense options and I've already done this to no effect. I've also not installed any 3rd party tools. I was editing queries when the problem began and I think I had
hit a <ctrl> or <alt> key combination key that started this problem.
I took a screen shot but when I hit the <ctrl> key, the options fade out but hopefully it can still be seen.

My guess is that you have installed any third party SQL-Server plug in and which is active. Click on Tools and check if it shows any add-on is there. You need to uninstall it from Control Panel then.

Setting query timeout in Microsoft SQL Server Management Studio

Hello,
We have several power users with access to SQL Management studio. They use it to write SQL queries. Realize there are other ways to access the db -- but we're stuck giving them Management Studio so no working around that issue.
My questions is how can we prevent them from locking up TempDB by writing poor SQL statements. Goal is to make them 'time out'. I have gone to Tools-->Options-->Query Execution--> SQL Server --> and set Execution time-out. Tested
this on my computer and this did NOT work. Set it to 15 seconds. Then, wrote a SQL statement (by clicking 'New Query') that took > 15 seconds and it ran successfully. Does anyone know why this setting did not carry over?
Any other thoughts on how to accomplish this would be appreciated.
Thanks,
Dan

I would have disconnected and reconnected, instead of just clicking New Query.

Same Query returning different result (Different execution plan)

Hi all,
To day i have discovered a strange thing: a query that return a different result when using a different execution plan.
The query :
SELECT *
FROM schema.table@database a
WHERE     column1 IN ('3')
       AND column2 = '101'
       AND EXISTS
              (SELECT null
                 FROM schema.table2 c
                WHERE a.column3 = SUBSTR (c.column1, 2, 12));where schema.table@database is a remote table.
when executed with the hint /*+ ordered use_nl(a c) */ these query return no result and its execution plan is :
Rows     Row Source Operation
      0 NESTED LOOPS (cr=31 r=0 w=0 time=4894659 us)
   4323   SORT UNIQUE (cr=31 r=0 w=0 time=50835 us)
   4336    TABLE ACCESS FULL TABLE2 (cr=31 r=0 w=0 time=7607 us)
      0   REMOTE (cr=0 r=0 w=0 time=130536 us)When i changed the execution plan with the hint /*+ use_hash(c a) */
Rows     Row Source Operation
   3702 HASH JOIN SEMI (cr=35 r=0 w=0 time=497839 us)
22556   REMOTE (cr=0 r=0 w=0 time=401176 us)
   4336   TABLE ACCESS FULL TABLE2 (cr=35 r=0 w=0 time=7709 us)It seem that when the execution plan have changed the remote query return no result.
It'is a bug or i have missed somthing ?
PS: The two table are no subject to insert or update statement.

System version : HP-UX v1Hard to say. You're using a very old and deprecated version of the database, and one that was known to contain bugs.
9.2.0.7 was really the lowest version of 9i that was considered to be 'stable', but even so, it's old and lacking in many ways.
Consider upgrading to the latest database version at your earliest opportunity. (or at least apply patches up to the latest 9i version before querying if there is bugs in your really low buggy version)

Query returning zero results for yesterdays same hour

But it is not returning any results because of the "having" clause. I know it should return results because all I want it to do is in one column have the V_ATT for the current time period, and in the 2nd column, have the V_ATT 24 hours ago. I've checked the data and I should get results back but can't seem to figure out why this is not working...

...You may have noticed that this site normally doesn't display multiple spaces in a row.
Whenever you post formatted text (including, but not limited to, code) on this site, type these 6 characters:
\(small letters only, inside curly brackets) before and after each section of formatted text, to preserve spacing.
That's just one of many useful things found in the forum FAQ {message:id=9360002}
But it is not returning any results because of the "having" clause. You're right:HAVING CASE
     WHEN d_dtm = (d_dtm - 24/24)
     THEN SUM (v_att_cnt)
     END > 0
Whatever d_dtm is, it's not d_dtm - 24/24, so the WHEN condition will never be TRUE. That means the CASE expression will always return NULL, and NULL is not greater than 0, so the HAVING condition will never be TRUE.

But probably not in this case, as you said.   What's more important is for you to post CREATE TABLE and INSERT statements for a little sample data, and the results you want from that sample data.

Basic NOT EXISTS query not returning any results

DB Version: 10gR2
One of our tables in the test schema is having less number of columns than the PROD shema.
To determine which are missing columns in this table in Test schema i did the following.
-----In Test Schema
CREATE TABLE XYZ2
(COL1 NUMBER);        ----------only one column
SQL > CREATE TABLE tables_test_list AS SELECT TABLE_NAME,COLUMN_NAME FROM USER_TAB_COLS;
Table created.--- In the prod schema
SQL> CREATE TABLE XYZ2
2 (COL1 NUMBER,
3 COL2 NUMBER       ----------- same table name with an extra column
4 );
Table createdAnd from the PROD schema i execute the following SQL to determine what are the columns that are missing in the TEST schema
select column_name from User_Tab_Cols outer
where table_name='XYZ2'
and not exists (select 1 from TEST_SCHEMA.tables_test_list inner where outer.TABLE_NAME=inner.TABLE_NAME )But the above query is not returning any results. Any idea why?

Actually, the example from the link I posted earlier:
[email protected]> (

CONNECT BY query doesn't return any results...

Hi All
I am trying to execute this CONNECT BY query...but it does not return any result.
Could anyone please suggests what am I doing wrong. Or how should I modify the query to get the results.
SELECT Distinct dt.DID FROM DEPT dt left outer join EMPLOYEE emp on dt.DID = emp.DID WHERE dt.parentid in (SELECT DEPT.DID FROM DEPT CONNECT BY PRIOR DEPT.DID = DEPT.PARENTID START WITH DEPT.PARENTID in (2000,-2000)) or dt.parentid=2000
Any help would be really really appreciated.
Thanks and Regards

Take the nested query and run it in SQL developer (or SQL Plus) against the database directly. Does it give any results? That query returning no results is the most likely cause of the problem.

Returning a result set/record from a dynamic query

There seems to be plenty of examples for using Native Dynamic Sql to formulate and execute a dynamic query, however there are no examples of returning a result set or records which contain the rows of data that are retrieved by executing the query. Could someone give us an example?

Welcome to the Oracle forum....
CREATE OR REPLACE PACKAGE curspkg_join AS
TYPE t_cursor IS REF CURSOR ;
Procedure open_join_cursor1 (n_EMPNO IN NUMBER, io_cursor IN OUT t_cursor);
END curspkg_join;
Create the following Oracle package body on the Oracle server:
CREATE OR REPLACE PACKAGE BODY curspkg_join AS
Procedure open_join_cursor1 (n_EMPNO IN NUMBER, io_cursor IN OUT t_cursor)
IS
v_cursor t_cursor;
BEGIN
IF n_EMPNO <> 0
THEN
OPEN v_cursor FOR
SELECT EMP.EMPNO, EMP.ENAME, DEPT.DEPTNO, DEPT.DNAME
FROM EMP, DEPT
WHERE EMP.DEPTNO = DEPT.DEPTNO
AND EMP.EMPNO = n_EMPNO;
ELSE
OPEN v_cursor FOR
SELECT EMP.EMPNO, EMP.ENAME, DEPT.DEPTNO, DEPT.DNAME
FROM EMP, DEPT
WHERE EMP.DEPTNO = DEPT.DEPTNO;
END IF;
io_cursor := v_cursor;
END open_join_cursor1;
END curspkg_join;
Dim Oraclecon As New OracleConnection("Password=pwd;" & _
"User ID=uid;Data Source=MyOracle;")
Oraclecon.Open()
Dim myCMD As New OracleCommand()
myCMD.Connection = Oraclecon
myCMD.CommandText = "curspkg_join.open_join_cursor1"
myCMD.CommandType = CommandType.StoredProcedure
myCMD.Parameters.Add(New OracleParameter("io_cursor", OracleType.Cursor)).Direction = ParameterDirection.Output
myCMD.Parameters.Add("n_Empno", OracleType.Number, 4).Value = 123
Dim myReader As OracleDataReader
Try
myCMD.ExecuteNonQuery()
Catch myex As Exception
MsgBox(myex.Message)
End Try
myReader = myCMD.Parameters("io_cursor").Value
Dim x, count As Integer
count = 0
Do While myReader.Read()
For x = 0 To myReader.FieldCount - 1
Console.Write(myReader(x) & " ")
Next
Console.WriteLine()
count += 1
Loop
MsgBox(count & " Rows Returned.")
myReader.Close()
Oraclecon.Close()
The above code is working in one of our application; which is using ref cursor as result set and get from procedure. I hope you can found more code by google and/or search in this forum as well; if above code is not useful to you.

Design a procedure which returns a result set of a select Query

Hi...
Can some one help me out with a brief design or work around for creating a stored procedure which runs a select Query and Returns a result set...
If not a stored procedure, at least a function which makes the job simple....
Awaiting help in this regard ........

Hi...
I am sorry for providing insufficient Info...
Actually I am using Oracle 10G DB...
I have a select Query..
Since I am a part of team which is building a Complete Data Driven site, Even an SQL Query and a PL/SQL function body was stored in the Table itself to bring in some kind of Dynamism in the site.... But the master table was loaded with a lot of data and hence Now we decided to Store everythin in a generic package..
I used REF CURSORS to store a result set of a simple SELECT Query.... and declaring it as an out parameter in my Procedure body so that the JAVA team can directly access the Procedure from the JAVA layer....
Now I want to know can I do anything more efficient to carry out the above operation....

Content Query Web Part filter not returning any results

This CQWP stopped working after moving a number of files to new locations. It is configured in the following way:
Source: Show items from the following site and all subsites
List type: Pages Library
We want to filter the list by the article date, last 30 days. Without a filter, results are returned. If ANY filtering is applied, NO results are returned, NO error messages.
I experimented with "Group items by" filter, but it also resulted in no results.
If I change the Source field to a subfolder, I can return filtered results.
Any ideas?

Make sure that ItemStyle.xslt is working fine, try to change the item style
for your content query web part, if it shows data then there your custom defined
item style is not working properly

SSIS query returns no results - same query in SQL management studio works
