SQL 2012 :: Requery Result Sets In SSIS

Feb 10, 2015

I 've got the below RESULT SET after several JOINs & deriving columns from different sources

STUD_ID, ANNUAL_YEAR, COURSES_ID, SUBJECTS_OPTED, CHAPTERS, YEAR_JOINED, Course_Tenure, Sub_ID, SUB_MARKS, EXAM_ID, ATTEMPT_YEAR, ATTEMPT_NO and many more.

Now, I've only one result set available in my DATA FLOW. And I want the below few,

1) STUD_RESULTS:TABLE : Evaluate COURSE-Annual year completion:
Have columns Students, Annual_yr, Results (IF ANY SUB _MARKS are below 35? 'PASS': 'Fail') and few more.
<--I've got to group the result set on STUD_ID and ANNUAL_YEAR.

2) STUD_COURSE_PERF: TABLE: for course performance.
I've got to group the result set on STUD_ID,ANNUAL_YEAR, Course_ID and the other essential

3) STUD_SUB_PREF: TABLE: Evaluating Subjects difficulty
I've got to group the result on STUD_ID,ANNUAL_YEAR, Course_ID, SUBJECTS_OPTED and other essentail.

How to use the only result set to carry on different evaluations?I Applied Multicast on the only result set.

SQL 2012 :: Tool To Compare Result Sets

Jun 11, 2014

I am looking for a tool to compare the result sets.

Is there any free tool or Microsoft built in tool that we can use to compare the result sets. Suppose if I change one thing in code and needs to test the am I getting the same result set or not? Instead of doing manually is there any way to compare both result set.

SQL Server 2012 :: Asynchronous Cursor Population Slow For Large Result Sets

Jul 2, 2015

so async cursor population is supposed to create the cursor and return the cursor id quickly, while the server works on async populating the results. For a keyset-driven cursor, SQL Server stores the key sets in tempdb, which it then uses to fetch data for cursor results. Anyway, this works fine for smaller tables, but I'm finding for large result sets, the async cursor population is very slow and indeed seems to approximate synchronous time. The wait stat I get while it is running (supposedly asynchronously) is TRANSACTION_MUTEX.

Example:
--enable async cursor
exec dbo.sp_configure 'cursor threshold', 0; reconfigure;
declare @cursor int, @stmt nvarchar(max), @scrollopt int, @ccopt int, @rowcount int;
--example of giant result set
set @stmt = 'select * from sys.all_objects o1, sys.all_objects o1';

[code]...

Note that using the SQL "select * from sys.all_objects o1" is much faster than "select * from sys.all_objects o1, sys.all_objects o2". However, if cursor population is async, I'd expect the time to return a cursor id to be similar between the two.

Integration Services :: SSIS - Database Query Result Sets Not Right

Jun 10, 2015

I have a general question I need a few pointers or explanations.  I have a top level Data Flow query in a SSIS package that has been running for years for which I have made some minor changes to pull additional fields and rectify a filter condition. 

I have noticed that when I run this same query, exactly as entered in the Data Flow task, in the SQL Server 2012 Management Studio, the query returns some 105,000+ records but when run in development by executing the package the top level task only indicates some 21,000 records returned.  Since there was not other transformations or filtering performed, I had expected the same record count and am not getting it.

Return 2 Result Sets

Feb 29, 2008

Hi, I'm trying to return 2 different result sets using the below query mapped to 2 different variables in my execute sql task. I've tried this with one task and 2 seperate tasks but can't get it to work. Is this possible using only one task? It keeps giving me a result set error.


SELECT COUNT(*) AS DeceasedCount
FROM AMGR_User_Fields_Tbl
WHERE (Client_Id = '' or Client_Id is NULL) and Type_Id = 53

SELECT COUNT(*) AS LostCount
FROM AMGR_User_Fields_Tbl
WHERE (Client_Id = '' or Client_Id is NULL) and Type_Id = 469

Multiple Result Sets

Jul 31, 2007

Hi,

I am aware that SSRS does not support stored procedures with multiple data sets, but what if the same stored procedure may only return one set based on a parameter?

For example, lets say if parameter @TableID = 0, the stored procedure returns 2 result sets. But if @TableID = 1, or @TableID = 2, the SP only brings back 1 result set. Is this also not supported?

When I try to do this it still only brings back the fields from the first table. Am I doing something wrong?

Thanks for any insight.

Paged Result Sets

Aug 28, 2006

What is the recommended mechanism for selecting paged results from SQL.

Presently I pass various params including the request Max Items Per Page and the requested page.

The I execute the query as a count with the search params.

Then comes the paging logic, which validates the page number against the request page and number of hits etc.

Then a temp table and record variables are created for the results.

Then I run the query again with a cursor and select the appropriate Items into the temp table based on the paging values (First Item and Last Item).

Then I return the temp table & some additional return params with the Total Hits etc.

The Stored procedure is accessed via an ADO.Net client and the system.data.IDBReader populates a .Net strongly typed collection and is for read only display.

Thanks for any input,

Martin.

How To Rank An Union Of Two Result Sets?

Mar 1, 2007

I am new to SQL Server Integration Services. I need to help here.

If there is only one result set, I could get rank info by putting DENSE_RANK expression inside of my select. My case is that I have two data source. After union of them, I need rank the result set and save result set plus rank info into the destination. I tried to use Derived Column component by using expression DENSE_RANK() over ( order by columnName ). But it does not like it.

Does anyone know how to achieve this?

Thanks!

How Come The Result Sets Do Not Match? Why No Error?

Feb 21, 2008

Scenario: Launch SQL Server 2005 Management Studio & Connect to Server, ie: ServerNameInstanceName. Click "New Query" Button

Running the following SQL Statement returns 842 rows but should return 1343:

SELECT A.id, C.PName, B.School
FROM users AS A
LEFT OUTER JOIN Bio AS B ON A.id = B.id
LEFT OUTER JOIN Groups AS C ON A.PName = C.PName ORDER BY A.Id

I get 1343 rows when I change Line 2 of SQL Statement to: "FROM dbName.dbo.users AS A".

Clicking "New Query" w/out first opening the database must run the query in the context of the Master Database??
I noticed in Sql Server 2000 if I connect Query Analyzer to the Server and run the query I get 842 & I can see that the default selected database is master. When I make the change mentioned above I then get 1343.

Why doesn't this produce an error though? I'd rather get an error than the wrong result set.

Limiting Rows Returned By Result Sets

May 20, 2008

In MySQL we use "SELECT (....) LIMIT 0, 10" to only return the first 0 to 10 records. Alternatively we could do "LIMIT 10, 20" to return the 10th to 20th records.

What's the equivilent of this in SQL Server?

Thanks

Save Multiple Result Sets To One File??

Aug 9, 2007

Hello,

Is it possible to save the results of several SP calls in a script, to one file?

Here's what I mean:
I want to run these 4 sp calls--
exec EPC_SP1 'aph','live'
exec EAUI_SP2 'noble','newswire'
exec EAUI_SP3 'noble',1
exec EAUI_SP4 5507,'live'

And save the results of each one of those calls to the same file, in other words, an APPEND

Is this or something like it possible in TSQL?

Help appreciated!

Thank you,

Transact SQL :: Get 2 Different Result Sets With GetDate Function

Aug 4, 2015

Periodically throughout the day a report is manually pulled from a SQL Server database.  Is their a way w/o me adding a field to the database to have the result set return the "new" results?  For example, lets say this is our DDL

Create Table OneTwoThree
(
id int
,date11 datetime
,firefly varchar(10)
)

Insert Into OneTwoThree Values (1, '08/03/2015 18:43:32.012', 'Hi'), (2, '08/03/2015 18:44:11.011', 'No'),
(3, '08/03/2015 19:36:33.011', 'Second'), (4, '08/03/2015 19:37:33.011', 'Alpha')

Prior I could use this syntax, but that was only with needing to generate 1 result set.  

Select id, convert(varchar(10), date11, 101) As [Date], firefly from onetwothree
where CONVERT(varchar(10), date11, 101) < CONVERT(varchar(10), GetDate(), 101)

Looking at my datetime values, let's say the 1st was generated at 18:45, obviously the 1st two records in the table would be returned. And let's say a 2nd time I need to generate I want to exclude the 1st two entries as they have already been verified. How can I do such w/o adding a field to the table?

SQL Server 2012 :: SSIS - Stop DataFlow Task If Result Set Is Empty?

Oct 7, 2014

I am trying to create a SSIS package that will create a csv of a dataset for daily events in the database. However there will be days that there was no activity and thus an empty dataset. The package still runs fine but I want to stop the package if the dataset is empty.

FLOW:

DATA FLOW task: get daily data and put in CSV file

FTP TASK: upload the file to FTP server

MAIL/Copy file task: Move the file and then send a confirmation mail on task completion status.

Pretty simple and it all works great, I do have a few complexities in there. What I would like to add and I am at a loss is at the beginning, if the OLE DB Task resultset is empty then move to Mail Task otherwise process normally. I have tried conditional split, derived columns, the only thing I haven't tried in Script task and am not sure about that yet.

Naming The Result Sets Returned By Stored Procedure

Jul 6, 2004

Greetings

I have a SQL Server stored procedure that performs several queries and therefore returns several "result sets" at any one time.

Wiring it up via ADO.NET I populate a DataSet with a number of items in the Tables collection - which is great - and I can give each item a name for identification purposes once the DataSet is populated.

But I'd like to know if there is some way I can set the names of each result set *within the text of the stored procedure*, i.e. before the DataSet gets populated.

Any help greatly appreciated.

How To Suppress Result Sets Returned From A Stored Procedure?

Aug 28, 2006

I have a novice question. How does one suppress result sets returned from a stored procedure?

I have created a procedure which makes use of multiple stored procedures . The purpose of this procedure (lets call it procA), is to count the rows returned from other procedures. The €œOther€? procedures will return rows having an unknown number of columns. I would like to limit any changes which may be needed to be made to the €œOther€? procs.

Once procA has collected all of the information (@@rowcount) from the inner procedures, then it will return a result set having several columns €“ mainly the subProcedure name and number of rows returned.

The purpose of procA is to query several subsystems and identify which ones need attention.

Cursor While Loop
exec @ProcName @ObjectName,@userID,@syncDate
set @recs = @@rowcount;


My c# program calls the sp as follows:

cmd = DataUtility.GetSQLCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "FetchAdminData";
cmd.Parameters.AddWithValue("@userID", userAlias);
cmd.Parameters.AddWithValue("@adminDate",userDate);
reader = cmd.ExecuteReader();

I do not wish to iterate over each resultSet when I am only interested in the last one. Any suggestions?

Package Hanging On OLE DB Command With Large Result Sets

Jul 13, 2007

I have an SSIS package (SQL 2005 SP2 and Visual Studio SP1) that does the following:



OLE DB Source --> Conditional Split --> OLE DB Command #1 --> OLE DB Command #2



The source reads from database A. Each row is variable-width and up to several KB wide, including two ntext columns.



Command #1 executes a stored proc in db A, using a bunch of inputs and two output parameters.



Cmd #2 executes an update in db B, using the two output params from cmd #1 as inputs.



When the rowset size is small, around 500, everything works fine.



However, when the rowset size is larger, around 5000, SSIS hangs when trying to execute cmd #2. The profiler shows that none of the cmd #2 updates are ever executed. No error messages are produced, and the connection never times out -- it just hangs forever.



If I replace the cmd #2 updates with a simple select, everything works fine. If I replace it with a stored proc that does an update, it hangs.



The work-around I came up with was to create a new table in db B, and do inserts into the table, but unless I'm missing something, this still seems like a bug...

Data Binding To A Stored Procedure That Returns Two Result Sets

Mar 6, 2007

Hi there everyone.  I have a stored procedure called “PagingTableâ€? that I use for performing searches and specifying how many results to show per ‘page’ and which page I want to see.  This allows me to do my paging on the server-side (the database tier) and only the results that actually get shown on the webpage fly across from my database server to my web server.  The code might look something like this:
 
strSQL = "EXECUTE PagingTable " & _
"@ItemsPerPage = 10, " & _
"@CurrentPage = " & CStr(intCurrentPage) & ", " & _
"@TableName = 'Products', " & _
"@UniqueColumn = 'ItemNumber', " & _
"@Columns = 'ItemNumber, Description, ListPrice, QtyOnHand', " & _
"@WhereClause = '" & strSQLWhere & "'"
 
The problem is the stored procedure actually returns two result sets.  The first result set contains information regarding the total number of results founds, the number of pages and the current page.  The second result set contains the data to be shown (the columns specified).  In ‘classic’ ASP I did this like this.
 
'Open the recordset
rsItems.Open strSQL, conn, 0, 1
 
'Get the values required for drawing the paging table
intCurrentPage = rsItems.Fields("CurrentPage").Value
intTotalPages = rsItems.Fields("TotalPages").Value
intTotalRows = rsItems.Fields("TotalRows").Value
 
'Advance to the next recordset
Set rsItems = rsItems.NextRecordset
 
I am trying to do this now in ASP.NET 2.0 using the datasource control and the repeater control.  Any idea how I can accomplish two things:
 
A) Bind the repeater control to the second resultset
B) Build a “pager� of some sort using the values from the first resultset

SQL Server 2012 :: Identify Sets Of Rows

Jul 15, 2015

I have the following sets of records:

ColA ColB
----- -----
21 A
22 A
23 A
24 B
25 B
26 D

What I want is to be able to identify a set sequence (1,2,3) based upon ColB such that I'd get the following result:

ColA ColB ColC
----- ----- -----
21 A 1
22 A 1
23 A 1
24 B 2
25 B 2
26 D 3

I know that I should be able to get it using ROW_NUMBER() OVER (PARTITION BY ColB ORDER BY ColA), but instead of getting the sequence (1,1,1,2,2,3) I get (1,2,3,1,2,1). Using DENSE_RANK gave me the same results.

Timeout For Recordset.Requery Method

Jun 8, 2007

I have an application coded in C++ using ADO. It has a very simple Recordset that opens a table and gets only one record without any filtering. The CommandTimeout is set to 600 (seconds). Once a while I get a timeout error generated by Requery() that puzzles me. I cannot imagine how Requery (i.e. close the Recordset and open it to get only one record in my case) can take 600 seconds.



Any clue would be greatly appreciated.
