I've a SSIS 2008 parent/child package solution to manage data transfers between two different data sources, so we can copy multiple tables and capture how many rows were transferred and duration for each transfer. This solution was working fine up until last week, when I made some changes to allow the package to perform a source count using standard SQL determined by an expression, or SQL provided from configuration tables, I also changed the package to Truncate or not the destination table, again controlled by configuration settings in a table. The child packages which perform the data flows have not changed!
The day after the controlling package promotion to live, I saw the bizarre behaviour of the Package log stating all rows transferred, but the actual table counts were not what the log stated, see attached file. The package solution works ok on other servers and was ok in DEV, but there were less tables and rows transferred.Re-running the package gave the same errors, but on some of the same tables and some different ones.
As it is the child packages doing the transfers and nothing has changed in them. I cannot see how the log would be able to say all rows are transferred and yet not all of the rows are actually moved?
Process output - where you can see counts and log Table transfer controller (as txt not dtsx)
An example of the data transfer child packages (as txt not dtsx)When I set the ExecuteOutOfProcess = True the package worked fine, unfortunately, this is not a good solution as SSIS 2008 does not tidy up the Dtshost.exe processes it starts and I'd be left with a memory issue after a very short time, we transfer hundreds of tables each day. ( I could write a .net script in the controlling package to kill the child processes, but that would still have hundreds of processes running before I could end them, as we have three parallel streams to allow a bit better performance.
Hello.I would like to learn all the possible ways that we can access and modify data in ASP .net 2.0 programmatically.for example one way would be like this: StringBuilder sql = new StringBuilder();sql.Append(" SELECT *"); //count the total number of recordssql.Append(" FROM dbo.tblJobTitle "); //get the connection string from web servicesstring strConnection = new sqlconnection.SQLConnection().GetSQLConnectString(sqlconnection.SQLDSN.SCIC);//Use the Microsoft.practices SqlDatabase object to execute our sql.SqlDatabase SqlHelper = new SqlDatabase(strConnection);SqlDataReader reader = (SqlDataReader)SqlHelper.ExecuteReader(CommandType.Text, sql.ToString());the i can loop through reader and get the data OR I can create a DataSet like this: SqlDatabase db = new SqlDatabase(strConnection);
DbCommand dbCommand = db.GetSqlStringCommand(sql.ToString());
DataSet dst = db.ExecuteDataSet(dbCommand);I want to know if there is a comprehensive book explainaning all these possible ways to access and modify data using C# under ASP .net 2.0I really really apreciate this.Thank you very much.
SQL Mobile database seems to not provide import/export utilities.
I think using Publication/Subscription is one of the solution, is it right?
Also, besides typing insert statement manually, there are any other ways to transform data to the SQL Mobile database?
I have a table called Cartype and there is field called typeid contained 5 rows such as A,B,D,C,E,F

I want to write the sql that output something like this

Is it possible to count total no. of rows in a table without scanning whole table??
View 10 Replies View RelatedHi,
I am using a foreach file to loop through mdb files kept in a folder and then transfer them to Sql server.
I want to do the following -
Sum the total no. of rows in mdb while the package executes
Sum the total no of rows transferred to Sql server.
Write them to a database (InitialRowCnt, FinalRowCnt, PackageNm, UserNm)
Note: Total = Total rows in all mdb files. so if there are 10 mdb files with 10 rows each, total = 100.
I saw a RowCount transformation..but just dont know where to place and what to do with it.
thanks
I have a view that I want to find all the rows that have a matching itemid and have more than 3 rows in them and group them by the itemid.
I am not quite sure how to do this.
Any ideas?

SELECT ID_AnagraficaRivenditaFROM dbo.AnagraficaRivenditeWHERE EXISTS(SELECT *FROM dbo.Flussi_RivenditeWHERE dbo.Flussi_Rivendite.CodiceProdotto = 631 AND dbo.AnagraficaRivendite.ID_AnagraficaRivendita = dbo.Flussi_Rivendite.ID_AnagraficaRivendita)AND EXISTS(SELECT *FROM dbo.Flussi_RivenditeWHERE dbo.Flussi_Rivendite.CodiceProdotto = 615 AND dbo.AnagraficaRivendite.ID_AnagraficaRivendita = dbo.Flussi_Rivendite.ID_AnagraficaRivendita)GROUP BY ID_AnagraficaRivendita
hi, in this query (in which I extract all ID_AnagraficaRivendita who have a correspondence in table Flussi_Rivendite with CodiceProdotto = 631 AND CodiceProdotto = 615), I would like to receive also a count of extracted rows... have you any idea?? Thank you ;)
Hi, I am trying to get the first row of what might be a group of any size of rows within an id that may contain a specific field. For eg
Row A = NoteID 1, FK_JobID 1, UnRead
Row B = NoteID 2, FK_JobID 1, UnRead
Row C = NoteID 3, FK_JobID 1, UnRead
I need the sql to return to just one Job (row) even though the job as 3 UnRead fields. But its returning 3 because its only doing what I'm asking. What I need it to do is just get the one Job (row) where any of the notes = UnRead.
I tried using Top 1, but that will only ever return one row and since I need it to return more than one job (row) it won't work.
Heres my attempt
DECLARE @UserID INT
SET @UserID = 4
SELECT User_Notes.BeenRead, Master_Jobs.By_Who, Master_Jobs.Next_Action, Master_Jobs.Due_Time, Master_Jobs.Due_Date, Master_Jobs.Contact,
Master_Jobs.Job_Title, Master_Jobs.JobID
FROM User_Notes INNER JOIN
Note ON User_Notes.FK_UN_NoteID = Note.NoteID INNER JOIN
Master_Jobs ON Note.FK_JobID = Master_Jobs.JobID
WHERE Note.FK_UserID = User_Notes.FK_UN_UserID AND
BeenRead = 'UnRead'
Thanks in advance
Hello,
Do anyone knows how can i count rows in all the tables in a database.
With select count(*) I can count rows only from one table .
TIA.
I'm new to MS SQL having used MySQL for several years now. I just can't figure out the syntax on counting or selecting rows
a) in the Last X (days, weeks, months...)
or
b) between "date X" and "date Y"
I've tried this to get the last week:
SELECT COUNT(*)
FROM contacts
WHERE CONVERT(datetime,timestamp) < (GETDATE() - DATEADD(DAY,7,GETDATE()))
...but I always get a total that includes rows outside the span.
Any suggestions? Thanks!
hey, how would i count the number of rows, with out using a loop??
thanks, Justin
The following query returns 2142 rows which is correct.
Code:
select COUNT(*), sum(v.currentMarket)
from TRMaster m
inner join TRValue v on v.Year = m.Year and v.Parcel = m.Parcel
inner join TRProp p on P.PropCode = V.PropCode and p.PropType = 'A'
where m.Year = 2013 and m.deleted = 0 and m.ReviewDateTime is null and m.Status = 1
group by m.Year, m.Parcel
having SUM(v.currentmarket) > 0
How can I convert this query so that it returns just the count of 2142?
I need to count how many rows are inserted and then how many updated from a table then put that result in a new table.

This is my sql string. It counts all the rows in Questions table but it should only count the rows where id in Quizzes matches the quiz column in Questions table.
"select Quizzes.name, Quizzes.id, count(Questions.quiz) as total from Quizzes inner join Questions on Quizzes.id=Questions.quiz"
Why isnt it doing what I want it to do?
I am trying to get the number of rows for each month.
table name:sitez
ID Name crDate access
===========================
1 Bob .. 2014-01-11 .. 1
2 Jerry .. 2014-01-22 .. 2
3 Jim .. 2014-05-06 .. 1
4 Jason .. 2014-12-11 .. 1
5 Jen .. 2014-11-21 .. 3
I am using the results to make a bar graph so I am querying the database for a given year and expecting 12 results back (running SQL 2012).
Select count(*) as ttl FROM sitez WHERE year(crdate) = 2014 and access = 1 group by all month(crdate)
This should return:
1
0
0
0
1
0
0
0
0
0
0
1
However when testing the script I was only getting back:
1
1
1
which didn't knowing which months were 0
By changing the GROUP BY to GROUP BY ALL, it now puts in the zeroes. However I'm still having issues with incorrect results.
When I query the database, the results for December 2014 shows '13' when I execute:
Select count(*) as ttl FROM sitez WHERE year(crdate) = 2014 and access =3 group by all month(crdate)
There are ZERO rows made with a year of 2014 and an access of 3.I verified this by going a straightforward select * from sitez where crdate = 2014 and access = 3
Why I'm seeing ghost results?
All I need is 12 results, ordered by crdate month.

Hi everyone:
I guess this should be a simple question but have not been able to find the answer, does anyone know how to make a SQL Sentence to return at least one row when counting?
SELECT COUNT(Id_Field), Field2 FROM Table1 WHERE Code_Field = 1 GROUP BY Field2
This will return 0 rows when the where criteria is not matched by any record on the Table1, but I would like to have one row counting 0 rows, in stead it returns no rows at all.
Thanks for any help.
My understanding from a previous thread was that ExecuteNonQuery() could be used to display the number of rows returned.
Does this also work when calling stored procedures and passing parameters?
I have code (shown) that perfectly calls and returns Distinct models downloaded by Country. Yet the rowCount variable displays a -1.
What should I do?Dim myCommand As New SqlClient.SqlCommand
myCommand.CommandText = "ap_Select_ModelRequests_RequestDateTime"
myCommand.CommandType = CommandType.StoredProcedure
myCommand.Parameters.AddWithValue("@selectDate", dateEntered)
myCommand.Parameters.AddWithValue("@selectCountry", CInt(selectCountry))
myCommand.Connection = con
con.Open()
Dim rowCount As Integer = myCommand.ExecuteNonQuery()
numberParts.Text = rowCount.ToString
con.Close() Thank you.
hello,
i have a stored procedure SELECT CommentID, UserName, CommentingDate
FROM Comm
WHERE PictureID = @PictureID
ORDER BY CommentingDate DESC
witch shows me the users who commented a Picture with PictureID = x
I need to add two rows at that stored procedure, one to show the number of total comments at that picutre (like counting the number of rows returned) and the second to show count the DISTINCT users who commented that picture
I tryied with COUNT but i have to use GROUP BY and i don't think this is good...
I hope you understand... please help me,
thanks
I would like to know the best way to count and display the number of rows in a given database table called memberinfo.
This should tell me how many members I have right?
Thanks
This is my SQL :
Select p.patientid,p.patientname,p.patientIc,pvi.DateOfAdmission,pvi.visitid,pvi.ward,pvi.bedno,pf.status,pvi.SurgeonName,(f.Title + ' ( Ver ' + (CAST(f.Version as Char(10))) + ')') as Title FROM patient p, patientvarianceinfo pvi,patientForm pf,Form f where (p.PatientName LIKE '%" & Name & "%' or p.PatientIc LIKE '%" & ic & "%' or pvi.Ward LIKE '%" & ward & "%' or pvi.Bedno LIKE '%" & bed & "%') and (p.patientid = pvi.patientid) and (p.patientid = pf.patientid) and (pvi.patientid = pf.patientid) and (pf.FormID = f.FormID)and p.patientid in (select patientid from patientform pf)how do i get the number of rows?
I've noticed that sometimes the # of rows specified in table properties tab is different from the # shown by select count(*) from tableA.
Why is this ?
(SQL 2k, sp2, indexed table)
Not sure how to do this but here is example of what I have
Table A
ID data1 data2 data3 data4
1 535 452 213 554
2 325 651 321 554
3 654 846 096 355
4 765 658 321 422
I want to have a select that will pull the following information out with count = the number of rows that have matching data in data4
ID data1 count
1 535 2
2 325 2
3 654 1
4 765 1
Right now I am using a VB script to loop thru get the current data4 value then using SELECT COUNT(data1) AS count FROM tbl_toolerrors WHERE data4 = {data4 value currently looking at}
Of course this take a bunch of trips to database and I think there should be a way to do it. I was thinking of a nested SQL querry like
Select data1, data2, ID, data3, (select count ...) Order by data1
can anyone help?
I have a table in Access 2007 that has about 30 field names and I want to have a count of how many unique rows there are in each field. I want to have these results put into another table that will just have the field name and then the count of how many unique rows there are.
I have code in VBA that will loop through my SQL and change out the field name, but I can't seem to get the SQL right before I can start looping it. For just one field name this would be what I have to count the unique names...
So far I have this:
INSERT INTO newtable
COUNT(*) FROM (SELECT Raw_Table.FieldName, COUNT(Raw_Table.FieldName) AS CountOfFieldName
FROM Raw_Table
GROUP BY Raw_Table.FieldName);
And its not going too well.
Is there a way to allow the count () to return a 0 for the rows with a NULL value instead of not returning that row?
