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 RelatedHello and thank you taking a moment. I have created a simple login page where the user will pass credentials. I have a sqldatasource that will query a database to see if the user exists. What I would like to do is have the user click a button after entering their credentials. When the button is clicked I would like the SqlDatasource SelectCommand to fire and if there are rows returned then redirect the user to a new page.
I know I can do this with ADO and a datareader with the HasRows property. But what I would eventually like to do is cache the data and then bind the cached data to a control(like a dataview) on the page the user is redirected to. If anyone can tell me how to get the Select command to fire on a button click I would be eternally grateful. Any help will be greatly appreciated.
Thanks,

I have a sql data source that runs a query that returns a users data (See below). I want to set the session variable "UserID" equal to the tkinit. How do I "bind" the session to a column from this select command? I tried this Session("UserID") = ("tkinit") but that doesn't work. I can hard code a session value, just can't figure out how to "bind" it from the sqldatasource..
<asp:SqlDataSource ID="getUserID" runat="server" ConnectionString="<%$ ConnectionStrings:xxxConnectionString %>" SelectCommand="SELECT [tkinit], [tklast], [tkfirst], [tkfirst]+' '+[tklast] as fullname FROM [yyy] WHERE ([login] = @login)"><SelectParameters><asp:Parameter Name="login" Type="String" /></SelectParameters></asp:SqlDataSource>
Hi,
I'm using SqlDataSource control.
Is there a way to know how many records a query has returned?
What is the C# code I use to do this?
I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.
select t1.a, (select t2.b from t2 where t1.c = t2.c) b from t1
I need to write that kind of sql to return me single value a and multiple values b on each of lines, like
a b
----------------------------

But if I execute that sql, I would get error like 'select Subquery returned more than 1 value'. Please help me find a solution, thanks!
Hi,
I have a problem that I would like help with.
I have to write an SQL Server 2000 stored procedure that returns rows from a table (a SELECT with an ORDER BY). A front end system calls the stored procedure and displays the returned rows. If there is more than one screen's worth of data (ie more than 20 rows returned from the table) then there is a requirement that the stored procedure only returns the rows for the screen ie, for screen 1 I need to return rows 1-20, for screen2 I need to return rows 21-40, screen 3 = rows 41-60.
The screen number will be passed into the stored procedure so I can work out what rows to return, the only problem is how can I tell SQL Server to only select the required rows (ie, say rows 21 to 40 from the returned rows). I can't see any arguments that allow selective rows to be returned (apart from TOP).
Any ideas??

What is the syntax for saving a single value returned by a Select statement in a variable? I have tried the following, but its telling me I "Must declare the variable '@TempCount'." which is already declared!
SET @SQL = 'Select @TempCount = count(*) FROM ' + @TblName + ' WHERE ' + .......
exec(@SQL)
Hello, I have a question on sql stored procedures.
I have such a procedure, which returnes me rows with ID-s.
Then in my asp.net page I make from that Id-s a string like
SELECT * FROM [eai.Documents] WHERE CategoryId=11 OR CategoryId=16 OR CategoryId=18.
My question is: Can I do the same in my stored procedure? (without sending it to page)
Here is it:
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
ALTER PROCEDURE [dbo].[eai.GetSubCategoriesById]
(
@Id int
)
AS
declare @path varchar(100);
SELECT @path=Path FROM [eai.FileCategories] WHERE Id = @Id;
SELECT Id, ParentCategoryId, Name, NumActiveAds FROM [eai.FileCategories]
WHERE Path LIKE @Path + '%'
ORDER BY Path
fileCategories table: (for information)Here is the screenshot of the table (10 kb )http://eai.w2o.ru/screen1.gif
Thank you

How is the best way to check for No rows returned from a Select statement in a Stored Proc? I have see this:
Code Snippet
Declare @res int
set @res = NULL
Select @res = dbKeyColumn
From aTable
If @res is null
then no rows returned.
Surely there is a better way??
Thanks.
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 am trying to pull results from an SQL Server DB into an dataset where a particular field (SMALLDATETIME) is within a particular date range. The code I was using worked fine when the database was in Access. I have made several changes already but am still getting 0 results returned when there is data that should be returned.
I was using in Access:
Dim StrSQL = "SELECT ID FROM myTable WHERE myDateField>=#" & startDate & "# AND myDateField<=#" & stopDate & "# ORDER BY ID"
I have changed this for SQL Server to:
Dim StrSQL = "SELECT ID FROM myTable WHERE myDateField>='01/01/2003 00:00:01' AND myDateField<='01/01/2004 23:59:59' ORDER BY ID"
But I am always returned 0 results even if the date range should return plenty of data. I have also tried using the BETWEEN structure with the same result.
Is there a particular format for the date I am comparing with?
Am I missing something else in my query?
The connection / permissions and everything else are correct as I can read and write data to the database in numerous other pages. It is just this date comparison that is not working.
Many thanks for any help or comments you can provide.
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

How can i get this number in the result.
Hi there,
I¡¦ve got a table with the following as well as other info:
User ID
DirectoryTypeID (int)
Region ID (int)
I need to run a query where I could get the region ID, then, in the second column, I¡¦d get all distinct directory types within that region. For example, if I run the query:
subRegionAreaID directoryTypeID
--------------- ---------------
3 1
3 2
3 3
3 9
If need these results to be:
subRegionAreaID directoryTypeID
--------------- ---------------
3 1, 2, 3, 9
Is this possible?
Many Thanks!! ļ

I am working on a company sign out sheet for our Intranet. The application accesses a sql database. I tried using a datareader as well as a dataset to access a small piece of information regarding the group that each employee belongs to in the company. My last attempt was to assign the value to the text property of a text box and evaluate the text from the text box with the Select Case but that did not work either.The application is supposed to generate an email to our receptionist as well as to the group technical assistant responsible for each group according to the value that is passed into the Select Case statement. With the datareader as well as the dataset and even now with creating a text box and accessing the text property, I was able to assign the group value to a variable (I can see the value in the subject of the email), but when the variable is supposed to be evaluated by the select case statement it skips right through all of the cases to case else and uses only the receptionist's address in the email as if it doesn't even see the value of the variable. I have searched for a possible answer to the problem I am but so far have had no luck. Any ideas? I included the part of the code that I am having trouble with: '********************************************************************************************' New DataSet is created to determine the group the employee belongs to so that the appropriate' group technical assistant is emailed when employee signs out'******************************************************************************************** ' declare variablesDim sqlGroup As String ' string variable to store sql statement for datasetDim BLGroup As String ' string variable to store the bl group of the employeeDim emailAddress As String ' string variable to store resulting email address Dim groupDS As DataSet ' dataset variableDim groupAdapter As SqlDataAdapter ' sql data adapter variable' sql statement to access group value from the databasesqlGroup = "SELECT BLGroup FROM BLGroupsView WHERE (RTRIM(fname) + ' ' + LTRIM(lname)='" & employee & "')" ' repopen the connection (leftover from working with the datareader)Connection.Open()' create new SqlDataAdapter applying sql statement and connectiongroupAdapter = New SqlDataAdapter(sqlGroup, Connection)' create new dataset groupDS = New DataSet()' populate the datasetgroupAdapter.Fill(groupDS, "BLGroupsView") ' get the value stored in the BLGroup column (only one row is returned at a time) BLGroup = groupDS!BLGroup' Create GroupTextBox TextBox control.Dim GroupTextBox As New TextBox()' Set options for the UserTextBox TextBox control.GroupTextBox.ID = "GroupTextBox"GroupTextBox.Visible = "False"GroupTextBox.Text = BLGroup' just trying anything with this next line, even when i didn't set this the select case statement did not seem to see the value returned by the variableGroupTextBox.runat = "server" ' use a select case statement to evaluate the value of the group (didn't work when I passed in the BLGroup variable eitherSelect Case GroupTextBox.TextCase "bh"emailAddress = "receptionist@myaddress.com; bhassistant@myaddress.com"Case "env"emailAddress = "receptionist@myaddress.com; envassistant@myaddress.com"Case "sw"emailAddress = "receptionist@myaddress.com; swassistant@myaddress.com"Case "fac"emailAddress = "receptionist@myaddress.com; facassistant@myaddress.com"Case "www"emailAddress = "receptionist@myaddress.com; wwwassistant@myaddress.com"Case ElseemailAddress = "receptionist@myaddress.com"End Select '*************************************************************************************************' set new message objectDim myMessage As System.Web.Mail.MailMessage = New System.Web.Mail.MailMessage()'**********************************************************' set message properties'********************************************************** myMessage.From = "me@myaddress.com"myMessage.To = emailAddressmyMessage.Subject = employee & " Signing Out at " & TimeOut.Text & " " & BLGroupmyMessage.Body = employee & " Signing Out at " & TimeOut.Text & " for " & Destination.Text & " will potentially return at " & EstTimeIn.Text'***********************************************************' set smtp server namesmtpMail.SmtpServer = "mailserver1"' send email using smtpsmtpMail.Send(myMessage) It sends the message and returns the BLGroup value everytime but only sends to the receptionist.

Hi all,
is there no a way to determine if a SqlCeDataReader has managed to return data (rows) from an executed SQL SELECT statement? I ask this because I have the following problem where I first need to determine if data (rows) are returned, if so, cycle through them and get the data out. But if I do the test to determine if data is returned (like I have in my code below) then the Reader.Read() is classed as reading a row, so when I do my 'while (Reader.Read())' this will then only work with data in the 2nd row.
if (Reader.Read()){ while (Reader.Read()) { //Get data from rows }}
I recall having this issue before as there doesn't seem to be a standard way of testing for data returned from a SELECT statement. I hope you can shed some light on this for me.
Thanks
I have a query that returns results based on information in several tables. The problem I am having is that is there are no records in the one table it doesn't return any information at all. This table may not have any information initially for the employees so I need to show results whether or not there is anything in this one table.
Here is my select statement:
SELECT employee.emp_id, DATEDIFF(mm, employee.emp_begin_accrual, GETDATE()) * employee.emp_accrual_rate -
(SELECT SUM(request_duration) AS daystaken
FROM request) AS daysleft, employee.emp_lname + ', ' + employee.emp_fname + ' ' + employee.emp_minitial + '.' AS emp_name,
department.department_name, location.location_name
FROM employee INNER JOIN
request AS request_1 ON employee.emp_id = request_1.emp_id INNER JOIN
department ON employee.emp_department = department.department_id INNER JOIN
location ON department.department_location = location.location_id
GROUP BY employee.emp_id, employee.emp_begin_accrual, employee.emp_accrual_rate, employee.emp_fname, employee.emp_minitial,
employee.emp_lname, department.department_name, location.location_name
ORDER BY location.location_name, department.department_name, employee.emp_lname
The section below is the part that may or may not contain information:
SELECT (SELECT SUM(request_duration) AS daystaken
FROM request) AS daysleft
So I need it to return results whether this sub query has results or not. Any help would be greatly appreciated!!!
TIA
hi all
Any day, another question. I love you guys.
I want to select a subset of data from a dataset returned by either another subquery or a union.
e.g. this is how i would do it in oracle, but i have no idea how this can be done in mssql or whether it's possible at all.
select * from
(
select col1, col2, col3 from table1
union
select col1, col2, col3 from table 2
)
where col1 = 'blah'
in essence oracle treats the data returned by the subquery as a table that it would select from.
how would i do the same in mssql?
thank you
James :)
I have a strange problem. I have some code that executes a sql query. If I run the query in SQL server query analyzer, I get a set of data returned for me as expected. This is the query listed on lines 3 and 4. I just manually type it into query analyzer.
Yet when I run the same query in my code, the result set is slightly different because it is missing some data. I am confused as to what is going on here. Basically to examine the sql result set returned, I write it out to an XML file. (See line 16).
Why the data returned is different, I have no idea. Also writing it out to an XML file is the only way I can look at the data. Otherwise looking at it in the debugger is impossible, with the hundreds of tree nodes returned.
If someone is able to help me figure this out, I would appreciate it.

View 1 Replies View Related(Newbie). I'm trying to: 1) check if the SELECT command has returned any records, and 2) put a msg box on the screen if there are no records returned from the SELECT query. The type of code I'm heading towards is: (but it's wrong). Thank you in advance for your C# code suggestion.
protected void SqlDataSource1_Selected(object sender, SqlDataSourceStatusEventArgs e)
{if (SqlDataSource1.SelectParameters.Contains is "") then
MessageBox.show ("There are no records available") ;
}
I'm sure that is really simple, but how do I pass a parameter with multiple value to a SQLdatasource?
ex: SELECT field1 from tblTableA where idTableA IN ( @Param1)
Let's say I want to pass 1,2,3,4 as Param1 (SELECT field1 from tblTableA where idTableA IN ( 1,2,3,4))
How I am supposed tu use the .SelectParameters.Add() to pass a list of integers instead of a single value??
Thanks in advance.
I am using <asp:SqlDataSource ID and for the Select Command, the following, where the WHERE clause ... for an exact match (=) works correctly:
SelectCommand="SELECT [PatientID], [MedRecord] , [Accession], [FirstName], [LastName], [Address1] FROM [ClinicalPatient] WHERE (LastName = @LastName) ORDER BY [LastName]DESC">
I would like to do a "LIKE" search where the LastName Parameter is matched using "LIKE". In this situation how would the syntax be written.... I tried:
LastName LIKE '%" & LastName & "%'"
But I get an error???? Any suggestions, please...
Thanks !!
I have a SqlDataSource object that is bound to a GridView control. I have configured the SqlDataSource with a default select command. Under certain values of query strings on the URL for this page (Default.aspx), I want to change the select command. So I put the statements in the Page_Load method for Default.aspx to define SqlDataSource1.SelectCommand. The changed SelectCommand works fine for the first page of GridView data and shows 5 GridView pages, but if I switch to one of the other pages, it seems to revert to the default SelectCommand (which generates 19 GridView pages). I assume I should put my code to change the SelectCommand somewhere else. Can someone help me with where to put it? Thanks!
View 1 Replies View RelatedIs it possible to use a WHERE-IN statement with a SqlDataSource control. For instance:

SelectCommand="SELECT [Id], [Name], [Phone] FROM [Table1] WHERE ([Id] IN @Id)">
<SelectParameters>

I'm hoping the gridview would then display a table with rows for records 1,3,5,7,11. Thanks for any help...

Let me simplify what I'm trying to do....
Basically, I want to run the following query by using SqlDataSource.
SELECT data FROM table WHERE row in ('one', 'two', 'three')
Simple enough....
So, here's my code.....which obviously doesn't work properly.
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnStr %>" SelectCommand="SELECT data FROM table WHERE row in (@username)">
<SelectParameters><asp:ControlParameter ControlID="TextBox1" Name="username" PropertyName="Text" Type="String" /></SelectParameters>
</asp:SqlDataSource>
<asp:Label ID="TextBox1" runat="server" Text="'one', 'two', 'three'" Width="125px" Visible="True"></asp:Label>
Is my SelectCommand correct? Thanks.
My compiler says that the line in bold below is illegal. The error msg I'm getting is: No overload for method 'select' takes '0' arguments. How can I correct this error and execute a SELECT?
protected void Button1_Click(object sender, EventArgs e)

I have a GridView (that uses SqlDataSource1) and a Dropdownlist. Depending upon the value selected on the DropDownList I need to select different stored procedures for the gridview. The problem is that I can do it without taking SqlDataSource1 by using DataSet or DataTable. But, I need to Use SQLDataSource1 for easy way of Header SORTING. So, is there any way to change the SQLDatasource1.SELECT Command dynamically. So that, I can use different queries for the Single DataGrid. I have attached the sample code of the SqlDataSource1 I'm using. I need to change the Command i.e. SelectCommand="usp_reports_shortages" to "usp_reports_shortagesbyID" and "usp_reports_shortagesbyDate" depending on the value selected in the dropdownlist. So, is there any way to do this????<asp:SqlDataSource ID="SqlDataSource1"
runat="server"
ConnectionString="<%$
ConnectionStrings:TESTDrivercommunication %>"
SelectCommand="usp_reports_shortages" SelectCommandType="StoredProcedure">
<SelectParameters>

Type="Int32" />
<asp:SessionParameter Name="week" SessionField="s_week" Type="DateTime" />
</SelectParameters>
</asp:SqlDataSource>
I am using the SqlDataSource to access the dB from my page. Basically this is what I do with it ds.SelectParameters.Clear();
ds.SelectParameters("Id", TypeCode.Int32, id.ToString());
DataSourceSelectArguments dssa = new DataSourceSelectArguments();
dssa.MaximumRows = 1;
dssa.AddSupportedCapabilities(DataSourceCapabilities.Page);
DataView dv = (DataView)ds.Select(dssa);
if (dv.Count > 0)
{
// collect the information
string title = (string)dv[index].Row.ItemArray[0];
}
And the SelectCommand attribute of the SqlDataSource is set in design mode to "SELECT * from vw_Items ORDER BY Category".
So, since I am trying to retrieve just the item with the given Id I was expecting just one record but when I step through I see that the data view has a count of 9 (all records in the table) !!!
What am I doing wrong here? why can't it return just one? as per the select statement which after adding the parameter should be something like "SELECT * FROM vw_Items WHERE ID = 5 ORDER BY Category

SQLDataSource.SelectCommand = "Select @@IDENTITY as 'Identity'"
