Rowcount - Returning Rowcount From SSIS To A Vb.net App Executing The Dtsx Package
Jul 7, 2006
I have a vb.net application that executes a simple flat file to sql table dtsx package. I want to capture the rowcount to display back to the user to verify the number of rows that were inserted or updated to the table. I have a Row Count component placed between the flat file source(without errors) and the destination component. I have assigned a variable named RecordCount to the Row Count component. So far so good I hope : )
Now, I also use a variable to "feed" the package the flat file source. This works fine, but I cannot figure out how to retrieve the row count information and how to assign that to the variable RecordCount.
Also, if anyone has any insight on the way to work with the OnProgress method in SSIS I would appreciate that as well. In SQL 2000 using DTS I create a "PackageEventsSink" that I had found online, and it worked great for monitoring the progress of the DTS. Can't seem to figure out how to get it to work in SSIS.
Thanx,
Mike

In sql I perform the following
SELECT * FROM
xlsdci x LEFT OUTER JOIN fffenics f ON f.[derived deal code] = x.[manual dcd id]
which gives me a row count of 2709 rows
In SSIS I have a merge join component (left outer)
left input = xlsdci with a sort order of 1 ASC on [manual dcd id] (OLE DB source component)
right input = fffenics with a sort order of 1 ASC on [derived deal code] (OLE DB source component)
which when run in the IDE gives me a rowcount of only 2594 rows
Why is this so?
Also if I change the join to INNER in the merge join, the number of rows drops dramatically to only 802.
Fair enough, I hear you cry, maybe there are IDs in the 'xlsdci' table that are not in the 'fffenics' table. Ok. But the following SQL reveals that there are only 14 rows(IDs) in 'xlsdci' that are not in 'fffenics'
SELECT * FROM xlsdci
WHERE [manual dcd id] NOT IN (SELECT [derived deal code] FROM dbo.fffenics)
What is going on here?

Hi,
I created a SSIS Package programatically based on the few threads here in this forum. This package just has a data flow task, during data transfer for every 1000 rows or so I want to update the status in a table in the database.
How do I achieve this?
As of now I just have a source and a destination, no transformations in between the flow. I'm not sure if rowcount will help, when I tried it using a onprogress even handler it always showed up as zero.
Thanks

i have 2 stored procedures: a delete and a select. the delete sp returns the rowcount properly. the select returns null. the code for both sp's is extremely simple and extremely similar. when i execute the select sp in server management studio the rowcount shows a 1 as expected. but the calling method gets null.
SP Code
ALTER PROCEDURE [dbo].[RetrieveEmployeeKeyFromAssignmentTable]
@assignmentPrimaryKey int,
@rowCount int OUTPUT
AS
BEGIN
SET NOCOUNT ON;
SELECT employeePrimaryKey FROM assignmentTable WHERE primaryKey = @assignmentPrimaryKey;
SET @rowCount = @@RowCount;
END
c# code
SqlConnection conn = GetOpenSqlConnection();
if (conn == null) return true;
SqlDataReader reader = null;
SqlParameter p1 = new SqlParameter(); SqlParameter p2 = new SqlParameter();
try {
SqlCommand command = new SqlCommand();
command.CommandText = "RetrieveEmployeeKeyFromAssignmentTable";
command.CommandType = CommandType.StoredProcedure;
command.Connection = conn;
p1.ParameterName = "@assignmentPrimaryKey";
p1.Value = assignmentPrimaryKey;
p2.ParameterName = "@rowCount";
p2.Direction = ParameterDirection.Output;
p2.Value = 0;
command.Parameters.Add(p1); command.Parameters.Add(p2);
reader = command.ExecuteReader();
if (p2.Value == null) //always true
any suggestions would be appreciated.
thanks. matt

I want to do a simple package that will send an e-mail if the rowcount of a query is > 0.
I add the rowcount data flow component and assign a variable cnt.
In the precendence constraint I add the expression @cnt > 0.
When I run, I get the error The expression "@cnt > 0" must evaluate to True or False.
Please help!

I would like to get the rowcount from a bulk insert task to validate that all the data is being inserted correctly. So far the only way that I can see this being done is through a trigger on the target tables. I would like to have this information inside the DTS package. Can anyone help me?
Thanks

Can anybody help ?
I need to get a limited set of records from sorted record set. For example, I have a table called Contacts which contains about 2000 records and I need to show records from 11 to 20 in the sorted order.
In Oracle I could use this query.
SELECT name FROM
(SELECT name, ROWNUM rnum from Contacts order by Name)
WHERE rnum between 11 and 20
Is anything equivalent available in SQL Server ? My need is to show
records page by page ( as in google/yahoo search ) in my asp page.
Thanks

i'm trying to get total rows found by query that uses top clause...for example:select top 10 myTable.* from myTable where myTable.number > 200let's say there are 13 rows matching that condition, and by using@@rowcount my result would be: 10.is there any way to get total row count, without affecting the TOPclause??? i believe that the mysql equivalent would beSQL_CALC_FOUND_ROWS().tnx...

I'm writing an INSERT, UPDATE and DELETE trigger on table A that needs to insert rows into a table B.
When a user issues a "SET ROWCOUNT" command to limit the number of rows, then does an insert, update or delete, the trigger is being limited to that number.
It is important that the trigger NOT be limited to ANY specific number of records, but it is undesireable for me to just wipe out the current "SET ROWCOUNT" setting for the user without their knowledge.
How do I get and preserve the current "SET ROWCOUNT" value from within my trigger, so I can cancel the limitation and then re-implement the setting once my work is done? I cannot find any documentation specifying where the ROWCOUNT value is set (I initially thought maybe the SYSPROCESSES table, but that doesn't seem to be it).
Example:
set rowcount 1
update TABLEA set val=val+1
<the TABLEA trigger fires, trying to insert multiple rows into TABLEB but is limited to a single row>
Ideas?

Hi, from what I can find, there isn't a way to get the number of rows returned from a SQLDataReader command. Is this correct? If so, is there a way around this? My SQLDataReader command is as follows:Dim commandInd As New System.Data.OleDb.OleDbDataAdapter(strQueryCombined, connInd)Dim commandSQL As New SqlCommand("GetAssetList2", connStringSQL)Dim resultDS As New Data.DataSet()'// Fill the dataset with valuescommandInd.Fill(resultDS)'// Get the XML values of the dataset to send to SQL server and run a new queryDim strXML As String = resultDS.GetXml()Dim xmlFileList As SqlParameterDim strContainsClause As SqlParameter'// Create and execute the search against SQL ServerconnStringSQL.Open()commandSQL.CommandType = Data.CommandType.StoredProcedurecommandSQL.Parameters.Add("@xmlFileList", Data.SqlDbType.VarChar, 1000).Value = strXMLcommandSQL.Parameters.Add("@strContainsClause", Data.SqlDbType.VarChar, 1000).Value = strContainsConstructDim sqlReaderSource As SqlDataReader = commandSQL.ExecuteReader()results.DataSource = sqlReaderSourceresults.DataBind()connStringSQL.Close()And the stored procedure is such:DROP PROC dbo.GetAssetList2;GOCREATE PROC dbo.GetAssetList2(@xmlFileList varchar(1000),@strContainsClause varchar(1000))ASBEGINSET NOCOUNT ONDECLARE @intDocHandle intEXEC sp_xml_preparedocument @intDocHandle OUTPUT, @xmlFileListSELECT DISTINCTAssetsMaster.AssetMasterUID,SupportedFiles.AssetPath,FROM AssetsMaster, OPENXML (@intDocHandle, '/NewDataSet/Table',2) WITH (FILENAME varchar(256)) AS x,SupportedFilesWHEREAssetsMaster.AssetFileName = x.FILENAMEAND AssetsMaster.Extension = SupportedFiles.Extension UNIONSELECT DISTINCTAssetsMaster.AssetMasterUID,SupportedFiles.AssetPath,FROM AssetsMaster, OPENXML (@intDocHandle, '/NewDataSet/Table',2) WITH (FILENAME varchar(256)) AS x,SupportedFilesWHEREAssetsMaster.AssetFileName <> x.FILENAMEAND CONTAINS ((Description, Keywords), @strContainsClause)AND AssetsMaster.Extension = SupportedFiles.ExtensionORDER BY AssetsMaster.Downloads DESCEXEC sp_xml_removedocument @intDocHandle ENDGOHow can I access the number of rows returned by this stored procedure?Thanks,James

Hello again everyone.....
Ok here's my problem.... This is definetly the strangest problem Ive had yet in my coding career..... anyways here it is:
I have a stored procedure which keeps a total number of hits for specific pages:
Procedure CMRC_Hits_Pages_Temp_Update
@Transaction nvarchar(20),
@Hits int = NULL,
@Page nvarchar(50) = NULL
AS
IF @Transaction = 'Delete'
BEGIN
DELETE FROM CMRC_Hits_Pages_Temp
END
IF @Transaction = 'Add'
BEGIN
CREATE TABLE #TempTableUpdate
(
Hits int
)
INSERT INTO #TempTableUpdate
(
Hits
)
SELECT
Hits
FROM
CMRC_Hits_Pages_Details
WHERE
Page = @Page
SELECT
Hits
FROM
#TempTableUpdate
IF @@Rowcount > 0
BEGIN
UPDATE CMRC_Hits_Pages_Temp
SET
Hits = Hits + @Hits
WHERE
Page = @Page
END
IF @@Rowcount < 1
BEGIN
INSERT INTO CMRC_Hits_Pages_Temp
(
Hits,
Page
)
VALUES
(
@Hits,
@Page
)
END
END
I've written it so if there hasn't been an entry for @Page, make a new one..... And if there is an entry allready for @Page, add @Hits to Hits.
Here's the strange part. When I run it in Query Analyzer (so I know there isn't a problem with my pages code), it works fine when I send @Page a value of 'Default' (As in my default page). But when I put any other value (ei. 'ProductsList', ProductDetails', 'test', 'Defauls') it doesn't work. It creates a new record even if there was a record for that page allready. I've tried erasing everything from the table over and over to give it a fresh start and it still only works for 'Default.'
I've tried every length of string possible thinking it may be the length, same problem.
It makes no sense to me why specific letters could make any difference in what this procedure does. A string is a string, right? Why should one string be more recognizable than another? Again, the most confusing thing I've enountered yet in my coding career.
I seem to always run into problems and think "this makes no sense" and then come to figure "Ohhh.... thats whats wrong..." But this problem here is definetely the cream.... It makes NO sense.....
Thank you to whomever can solve this mystery..... (If it is much of one....)
Just incase the Table info is important:
I have two Columns: Hits, int (4) & Page, nvarchar (50)

I was testing some checking techniques to add to my SPs while retreiving data or inserting a series of reocords to a series of tables.
Check this testing small piece of code:begin transaction t1
select * from roles where rolename = 'student'
if @@rowcount = 0
goto cleanup
select * from users
if @@rowcount = 0
goto cleanup
commit transaction t1
goto endup
cleanup:
rollback transaction t1
SET ROWCOUNT 0
endup:
print @@rowcount
On one of the testing cases: I made the first query return 1 record and the second returned 5 records, so we ended up at the label "endup", I printed out the RowCount it was 0, does the commit transaction reset that variable?
In addition, are there smart and effective techniques to check against validity of the query statements inside the SP, for example, I can use @@ERROR and @@ROWCOUNT in a transaction based SP to know if I proceed with sub queries, are there more stuff like that?

I want to create a stored procedure where I pass the name of a view, the number of rows in the view is determined. If the number of rows is zero, I want the sp to fail with an error code that would bring the DTS that executed the sp down. Here is the sp so far. Note that I am EXECuting a sql string because the FROM clause cannot accept a passed variable. Problem is I need the value of my counter variable(@resultcount) to be available after the EXEC statement. Any ideas on how to do this?
CREATE PROCEDURE CheckForEmpty
@tablename varchar(50)
AS
declare @resultcount integer
declare @sSql varchar(255)
--SP to check for rowcount in passed table name. Useful in DTS steps to stop load process if no rows in sending table.
set @sSql = 'set @resultcount = (select count(*) from ' + @tablename + ')'
exec (@sSql)
if @resultcount = 0 RETURN(-99) else return(0)

I have an sp that returns data to a client application. I wonder how I'd go about doing the following: I need to implement a maximum amount of rows on a combination of several columns that are part of the resultset.
fe; Col001, Col002, Col003 are the result, the unique count of Col001 and Col002 are two;
Col001, Col002, Col003
1, 'aa', 'someOtherValue'
1, 'aa', 'someThingElse'
1, 'aa', 'ratherSillyActually'
2, 'aa', '...'
I'd return:
1, 'aa', 'someOtherValue'
1, 'aa', 'someThingElse'
2, 'aa', '...'

I'm coming from Oracle world and my knowledge about SQL Server is quite limited so I apriori apologize for probably stupid questions
DB version is SQL Server 2005.
The business scenario is - there is search form with many criteria. User may enter very unrestrictive criteria matching probably millions of rows. To prevent that we'd like to show him no more than N rows (N ~200). Any rows matching criteria are good enough, however these FOUND rows we'd like to sort. I do not want to find all potentially X million rows, then sort them and only then show forst N rows.
So in Oracle I know how to do that. I just find N rows in subquery, and then in outer query sort them. So I avoid to find all rows and then sorting millions of rows.
Here is an example:
Code Block
SQL> create table t (id number, data varchar2
Table created.
SQL> insert into t values (1, 'aaa');
1 row created.
SQL> insert into t values (2, 'bbb');
1 row created.
SQL> insert into t values (3, 'ccc');
1 row created.
SQL> select * from (
2 select * from t where rownum <=2)
3 ;
ID DATA
---------- --------------------
1 aaa
2 bbb
SQL> ed
Wrote file afiedt.buf
1 select * from (
2 select * from t where rownum <=2)
3* order by data desc
SQL> /
ID DATA
---------- --------------------
2 bbb
1 aaa
However how can I avoid sort of potential big result in SQL Server? I've searched google but unfortunately found nothing.
I've tried to use both TOP and SET rowcount without success i.e. from these examples I assume that DB will find ALL rows matching where clause then sort them keeping only first N. It seems that order by clause in outer query is pushed into inner query both for top and set rowcount.
Code Block
create table t (id integer, data varchar(20));
insert into t values (1, 'aaa');
insert into t values (2, 'bbb');
insert into t values (3, 'ccc');
select * from (
select top 2 * from t) as q
1 aaa
2 bbb
select * from (
select top 2 * from t) as q
order by data desc
3 ccc
2 bbb
set rowcount 2
select * from (
select * from t) as q
1 aaa
2 bbb
set rowcount 2
select * from (
select * from t) as q
order by data desc
3 ccc
2 bbb
And I'd like to avoid sort because of two reasons:
1) I predict that generally finding all rows will be much more costly than finding just any no more than N
2) Sorting all found rows also probably will be slower than just N (however DB has to find only first N rows, so not ALL rows should be sorted/kept sorted)
Are my concerns reasonable? If yes what can I do to just find N rows and sort only these?
TIA, Gints
