Hi,This is a very simple question but I don't have any idea of how to do it.Says I have a table with 50 records. How do I know the number of record have been return by sqldatasource when it execute a SELECT sql statement that contains a WHERE clause. Says the 30 records match the SELECT statement, what code do I have to write in order to display the number 30? Thanks
View 1 Replies View RelatedHi all,I have a stored procdure which does a select and returns the recordsdirectly -i.e. Not in output parameters e.g:CREATE PROCEDURE up_SelectRecs(@ProductName nvarchar(30)) ASSELECT *FROM MyTableWHERE [Name]=@ProductNameIn another stored procedure I need to do the following:SELECT COUNT(*)FROM MyTableWHERE [Name]=@ProductNameAs the select queries are actually a lot more complex that this, I'drather not duplicate the select code in 2 sp's to save the maintenanceeffort - I'm looking for a way to execute the first procedure from thesecond and just count the records returned - something like:SELECT Count(*)FROM EXEC up_SelectRecs @ProductNameAny way to achieve this?Thanks all--James

I hope you understand... please help me,
thanks
Iam using front page to dispalay my results.
At the bottom it shows me 1/10 i.e 1st page of 10 pages.
but what do i do if i want it to be shown as 1-10 out of 100 (if each page contains 10 results).
or it would be really good if i get count of both no. of recors as well as no. of pages.
I want to show the number of rows returned by a select query in the result.
e.g. select policy,policynumber,datecreated,Firstname, '-' as recordcount from policy
If it returns 5 rows, then the 'recordcount' need to show '5' in all row in the result
OutPut
0y96788,HGYG564,29/07/2013,SAM,5
FJUFBN7,JLPIO67,29/07/2013,Test,5

How can i get this number in the result.
The following sproc returns no records in query analyzer, although it doesn't error out either. Last time adding the length to the end of the variable fixed this problem, but this time it's an integer type which doesn't accept a length. Any ideas?

I have a simple report with a group header, details and footer. How do I display a message to inform users when no data is returned when they enter a parameter which returns no records - at the moment my report returns a blank screen, it would be more useful if I could output the following
'Parameter Name' does not exist.

The following statement gives the error that multiple records are returned. I am attempting to pick one weight out of a group of three, the three have the same ResidentID and different dates in the table variable @WeightReportRaw. If I hard code the ResidentID, ResidentID = 6, it works fine. The variable @intMonth3 passes in a month number ans dosen't seem to be a problem.
What am I missing, Thanks in advance for any help.
update tblResidentWeightsTemp set FirstWeight =
(select RWeight from @WeightReportRaw as W where ResidentID = W.ResidentID and month(W.RWeightDate) = @intMonth3)
I have a function that opens a connection to an SQL database, issues a
SELECT command, and reads the records with an OleDbDataReader. As the
records are read, any that match certain criteria are deleted with a
DELETE command. Simplified example code is shown below:
Dim dbCmd As OleDb.OleDbCommand = New OleDb.OleDbCommand()
dbCmd.Connection = New OleDb.OleDbConnection(UserDbConnString)
dbCmd.CommandText = "SELECT * FROM [User] ORDER BY UserID"
dbCmd.Connection.Open()
Dim reader as OleDb.OleDbDataReader = dbCmd.ExecuteReader(CommandBehavior.CloseConnection)
While reader.Read()
If reader("SomeColumn") = SomeCalculatedValue Then
Dim dbCmd2 As OleDb.OleDbCommand = New OleDb.OleDbCommand()
dbCmd2.Connection = New OleDb.OleDbConnection(UserDbConnString)
dbCmd2.CommandText = "DELETE FROM [User] WHERE UserID = " + reader("UserID")
dbCmd2.Connection.Open()
dbCmd2.ExecuteNonQuery()
dbCmd2.Connection.Close()
End If
End While
reader.Close()
This code worked well with an MS Access database, but when I changed to
SQL Server, I get a database timeout error when attempting to do the
DELETE. I suspect the reason is that the connection the reader has open
has the record locked so it cannot be deleted.
The SQL connection string I am using is something like this:
UserDbConnString = "Provider=SQLOLEDB; Server=(Local); User ID=userid; Password=password; Database=dbname"
The connection string I used for MS Access included the property
"Mode=Share Deny None". I wonder if there is some similar way to tell
SQL Server to allow editing of records that are open for reading with
an OleDbDataReader.
Any help would be appreciated.
In my database I have an Audit table, that keeps track of teams worked upon the same record in a workflow.I need to find out how many records have been returned to the first team for correction ?The column 'Status' is numbered from 1 to 6 and Column 'EditTime' saves the time when record has been edited.how many records have been returned for correction and identify those records.

Thank you very much for your kind attention.
I got a problem with the records returned by inner join query. It is weird as in table a I with records r1, and in table b with records r2 (r1>r2), but the returned record number r3 is greater than r1? That is so strange. As the reasonable records returned should be less than r1?(inner join on attribute a). What probably is the cause of the problem? I am looking forward to hearing from you and thank you very much.
With best regards,
Yours sincerely,
I would like to make a listbox only appear if there are results returned by the SQL select statement. I want this to be assessed on a click event of a button before the listbox is rendered.I obviously use the ".visible" property, but how do I assess the returned records is zero before it is rendered?
View 3 Replies View RelatedI would like to use sp_send_dbmail, but I only want to send mail if there are any records returned.
I have found some solutions, but you must always first check if there is any record and later you can call "sp_send_dbmail" and within you must again query database for results.
What I want to do is to query database just once, because I dont want to use server performance two times. Query is bit complicated.
Hi,
I'm using SqlDataSource control.
Is there a way to know how many records a query has returned?
In my ASP page, when I select an option from the drop down list, it has to get the records from the database stored procedure. There are around 60,000 records to be fetched. It throws an exception when I select this option. I think the application times out due to the large number of records. Could some tell me how to limit the number of rows to be returned to avoid this problem. Thanks.
Query
SELECT @SQLTier1Select = 'SELECT * FROM dbo.UDV_Tier1Accounts WHERE CUSTOMER IN (SELECT CUSTOMERNUMBER FROM dbo.UDF_GetUsersCustomers(' + CAST(@UserID AS VARCHAR(4)) + '))' + @Criteria + ' AND (number IN (SELECT DISTINCT ph1.number FROM Collect2000.dbo.payhistory ph1 LEFT JOIN Collect2000.dbo.payhistory ph2 ON ph1.UID = ph2.ReverseOfUID WHERE (((ph1.batchtype = ''PU'') OR (ph1.batchtype = ''PC'')) AND ph2.ReverseOfUID IS NULL)) OR code IN (SELECT DISTINCT StatusID FROM tbl_APR_Statuses WHERE SearchCategoryPaidPaymentsT1 = 1))'
When querying a bit field, I am encountering a problem with MS SQLServer returning a larger number of records for a table than theactual number of records that exist within that table.For example, my customer table has 1 million unique records, so theresults of the following query are as such:select count(customer_nbr) from customer = 1,000,000There is bit field in the customer table that denotes whether acustomer has placed an order with us called. That flag is calledorder_flagIf I run the following query:select count(customer_nbr) from customer where order_flag = 1The result is 3,000,000 records.There is no logical way that this is possible, as my table onlycontains 1,000,000 unique records and the number of customers with anorder should be a subset of this.If a run the above query with a distinct before customer number, I getthe results I want:select count(distinct customer_nbr) from customer where order_flag = 1600,000 records.So while I can get to the answer I want, I have no idea why I amreturning incorrect values if I don't select distinct.Can anyone help? I checked microsoft support and message boards buthaven't seen anything.I should note that the bit field is indexed.I am not sure if that isthe problem or not.

Hello All,
I'm wondering if you guys can help me with a problem to count every record in a table; however, I must match this table with another table to get the category names. I have tried this SQL statement in the SQL Express and it works very great.
SELECT aspnet_Category.CategoryName, COUNT(*) AS Expr1FROM aspnet_Category INNER JOINaspnet_resources ON aspnet_Category.ApplicationID = aspnet_resources.ApplicationId AND aspnet_Category.CategoryID = aspnet_resources.CategoryIDGROUP BY aspnet_Category.CategoryNameORDER BY aspnet_Category.CategoryName
However, when I tried to put this into my code, it gives me a error. <System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Select, True)> _Function GetDataByCount_CategoryID() As CategoryDataTableGetDataByCount_CategoryID = Adapter.GetDataByCount_CategoryIDEnd FunctionFailed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.
Can you please help me to fix this error?
Thank you, Vic.
I need to export records to a text file and simply index them. i.e. in the pipe delimited file I need a column with the ordinal value of each row.
Example:
1|"Jane Doe"|"23 Western ave"|...
2|"Jamie Delom"|"5 East Street|...
3|"Nat Girshon"|"5678 Main Street|...
.

Would anyone be able to tell me how I could build this within the SQL query without creating a physical table and using IDENTITY functions?

Hi all,
I've got a quick question.
How would I count the number of records between two dates.
I started with something like this.
SELECT COUNT(*) AS COUNT, dtAdded
FROM tSurveyPerson
WHERE (dtAdded BETWEEN '2004-03-01' AND '2004-04-01')
GROUP BY dtAdded
but as you probably all know this ain't right. I would like to get just the number of records.
Thanks
