ExecuteScalar - Count(*)
Mar 25, 2007
i have Cust table with 5 columns (Name, Add, Contact, UserID, Passwd)
my sql statement is not working correctly..
"SELECT COUNT(*) FROM Cust WHERE UserID='" + textBoxEmail + "'AND Passwd='" + textBoxPW + "'"
what maybe the problem? i have 1 record and when im running it, whether the input is right or wrong, the count is always zero(0). i think the problem is in my sql statement(maybe in the where clause) because i tried counting the records by "select count(*) from cust" and it correctly says 1 record. pls help!

Howdie y'all!
I'm trying to do an executescalar() on the next stored procudure...
SELECT COUNT(*) FROM tblUsers WHERE UserEmail = @UserEmail;
Strangely enough I get SqlServer exception that tells me there's a syntax error.
Is there something I'm overseeing?
Cheers,
Wes

private void buttonLogin_Click(object sender, EventArgs e)
{
SqlConnection conn = new SqlConnection();
conn.ConnectionString = "Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirecto ry|\PEService.mdf;Integrated Security=True;User Instance=True";
conn.Open();
string strSQL = "Select Count(*) as ctr From Cust Where Email=" + textBoxEmail + "and Passwd=" + textBoxPW;
SqlCommand cmd = new SqlCommand(strSQL,conn);
int ctr=(int)cmd.ExecuteScalar();
if (ctr == 1)
MessageBox.Show("Correct");
else
MessageBox.Show("Wrong");
conn.Close();
}
i have this code for my login form. when i remove conn.Open(); in the code
it says... ExecuteScalar requires an open and available Connection. The connection's current state is closed.
and when i put conn.Open();
it says... An attempt to attach an auto-named database for file C:... failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
what is the problem?

Okay so here's a wierd one. I use SQLYog to peek into/administrate my databases.I noticed that this chunk of code is not producing a value... Using Conn As New MySqlConnection(Settings.MySqlConnectionString)
Using Cmd As New MySqlCommand("SELECT COUNT(*) FROM tbladminpermissions WHERE (PermissionFiles LIKE '%?CurrentPage%') AND Enabled=1", Conn)
With Cmd.Parameters
.Add(New MySqlParameter("?CurrentPage",thisPage))
End With
Conn.Open()
Exists = Cmd.ExecuteScalar()
End Using
End Using Exists is declared outside of that block so that other logic can access it. thisPage is a variable declared outside, as well, that contains a simple string, like 'index.aspx'. With the value set to 'index.aspx' a count of 1 should be returned, and is returned in SQLYog. SELECT COUNT(*) FROM tbladminpermissions WHERE (PermissionFiles LIKE '%index.aspx%') AND Enabled=1 This produces a value of 1, but NO value at all is returned from Cmd.ExecuteScalar(). I use this method in MANY places and don't have this problem, but here it rises out of the mist and I can't figure it out. I have no Try/Catch blocks so any error should be evident in the yellow/red error screen, but no errors occur in the server logs on in the application itself. Does anybody have any ideas?

The following query returns 0 when executing in Query Analyzer:SELECT isnull(Count(*),0) as total FROM SplitDetail WHERE SiteCode = 14 AND ProjectID = 4367Yet ExecuteScalar() in vb.net return a -1.
Any ideas on what I might be doing wrong... ?

Hi all
I am currently developing a Help Desk for our company. One of my problems is Data lookups in other tables within a SQL 2000 DB. i.e. Client Details and Information in one table (hd_clients) and Client History (hd_history) in another.
'hd_history' contains a column called 'c_id' which references the 'hd_clients' table 'c_id' column A typical One-to-Many relationship. When a user goes to the Help Desk's Service page. I want to display the client's name in one of my GridView's Databound Columns. See Below:
...
<asp:TemplateField HeaderText="Client" SortExpression="c_id">
<ItemTemplate>
<asp:Label ID="lblClient" runat="server" Text='<%#GetClient(Eval("c_id")) %>' />
</ItemTemplate>
</asp:TemplateField>
...
This then calls: GetClientName - Which is as follows.
...
Public Function GetClientName(ByVal ClientID)
Dim ScalarValue As String = ""
Dim myConnection As New SqlConnection("Data Source=XXX; Initial Catalog=XXX; uid=XXX; pwd=XXX")
Dim myCommand As New SqlCommand("SELECT [Name] FROM [hd_clients] WHERE [c_id] = @ClientID", myConnection)
myCommand.Parameters.Add("@ClientID", SqlDbType.Int)
myCommand.Parameters("@ClientID").Value = ClientID
Try
myConnection.Open()
ScalarValue = myCommand.ExecuteScalar
Catch ex As Exception
Console.Write(ex.Message)
End Try
If ScalarValue > "" Then
Return ScalarValue.ToString
Else
Return "<span style='color: #CCCCCC'>- NULL -</span>"
End If
End Function
...
This works perfectly on my Laptop (which runs the IIS and SQL Server Instances + VS2005). But, when placed on our production server brings back the '- null -' value instead of the Client's Name. I have set both machines up in exaclty the same way - and cannot get this to work. I have tried 'ExecuteReader' but from what I understand is 'ExecuteScalar' is better for single value lookups.
Any help in this matter would be great and really appreciated. Thanks.
David

Hey folks, I was just learning how to work with ScopeIdentity and I found out I needed somthing called executescalar. Things seem to be working really well, and I think I did it write, except I'm having one strange little oddity. Everytime my page writes to my databases, it writes rows. I'm really curious to know what I did wrong. Any ideas? Thank you as always :-)
Public Sub newoptic(ByVal sender As Object, ByVal e As System.EventArgs) Handles newpostBTN.Click
If newpostTXTBX.Text = "" Then
Exit Sub
End If
Dim mySQL As String = "insert into msg_topics (topic_title, topic_forum_id) values (@topicTITLE, @forumID); Select Scope_Identity()"Dim myConn As New SqlConnection(System.Configuration.ConfigurationManager.AppSettings("DBconnect"))
Dim cmd As New SqlCommand(mySQL, myConn)cmd.Parameters.AddWithValue("@topicTITLE", newposttitleTXTBX.Text)
cmd.Parameters.AddWithValue("@forumID", HDN_topic_forum_ID_LBL.Text)
myConn.Open()Dim topic_ID_holder As Integer = cmd.ExecuteScalar()
HDN_topic_id_holder_LBL.Text = (topic_ID_holder)
cmd.ExecuteNonQuery()
myConn.Close()
End Sub
Oh, one more quick question if whoever responds knows the answer. Why do I need a semi-colon here "@forumID); Select" ? The websites I learned about this from didn't explain that, and I've never used a semicolon in my select statements before, so I figured there must be something special about it.
Thank you

I need to execute stored procedure which is suppose to return GUID to my IF statement and if it is Nothing I execute other Stored procedures else some other procedures. My problem is that even though by looking at the data I know that after the execution of the procedure it should return some guid value it doesn't anybody who had the same issue??? That is the code block where I am trying to return guid from my stored procedure: getGroupID.Parameters("@GroupName").Value = dr.Item("Group ID").ToString() If getGroupID.ExecuteScalar() = Nothing Then 'Find Group by IP address if input Data Table doesn't have group getGroupIDByIP.Parameters("@IP").Value = dr.Item("IP").ToString() If getGroupIDByIP.ExecuteScalar() = Nothing Then insertGroup.Parameters("@GroupID").Value = Guid.NewGuid insertGroup.Parameters("@Group").Value = dr.Item("Group ID") insertGroup.Parameters("@ACCID").Value = getAccID.ExecuteScalar() insertGroup.ExecuteNonQuery() command.Parameters("@Group_ID").Value = getGroupID.ExecuteScalar() Else command.Parameters("@Group_ID").Value = getGroupIDByIP.ExecuteScalar() End If Else command.Parameters("@Group_ID").Value = getGroupID.ExecuteScalar() End If Thank you

I have a method like follows:
string EmpCount = null;
DateTime _dtstart = Convert.ToDateTime(txtStart.Text.Trim());
DateTime _dtend = Convert.ToDateTime(txtEnd.Text.Trim());SQLProvider sqlp = new SQLProvider(System.Configuration.ConnectionStrings["ConString"].ConnectionString);string SqlText = @"
select count(*) from employee
where activeemp=1 and startdate BETWEEN @dtstart and @dtend;
using (sqlp.Connection) {
sqlpm [] param = {
new sqlpm("dtStart", _dtstart),
new SqlP("dtEnd", _dtend)
};
}EmpCount = sqlp.ExecuteScalar(SqlText, param).ToString();
return Convert.ToInt32(mbrCount);
Then the method I am calling is:public Object ExecuteScalar(String sqlText, Sqlp[] param)
{try
{
//Some Code here
}
}
So in the calling method (ExecuteScalar), the second parameter is defined as an array, is it ok to have an array in the called method too?

I have code that has worked just fine for some time, and now all of the sudden I am having an issue. I have a simple INSERT statement built and then make the following call:
RecordID = cmd.ExecuteScalar
I have never had a problem with this before. The RecordID of the newly inserted record is returned into the RecordID Integer varibale. All of the sudden, the varibale has a value of 0 (null I assume is being returned), but yet the INSERT worked just fine. I can check the table in SQL and it is populated with no issues.
No exception is thrown of any type or anything. Does anybody know what may be happening?

The following query returns a value of 0 for the unit percent when I do a count/subquery count. Is there a way to get the percent count using a subquery? Another section of the query using the sum() works.
Here is a test code snippet:
--Test Count/Count subquery
declare @Date datetime
set @date = '8/15/2007'
select
-- count returns unit data
Count(substring(m.PTNumber,3,3)) as PTCnt,
-- count returns total for all units
(select Count(substring(m1.PTNumber,3,3))
from tblVGD1_Master m1
left join tblVGD1_ClassIII v1 on m1.SlotNum_ID = v1.SlotNum_ID
Where left(m1.PTNumber,2) = 'PT' and m1.Denom_ID <> 9
and v1.Act = 1 and m1.Active = 1 and v1.MnyPlyd <> 0
and not (v1.MnyPlyd = v1.MnyWon and v1.ActWin = 0)
and v1.[Date] between DateAdd(dd,-90,@Date) and @Date) as TotalCnt,
-- attempting to calculate the percent by PTCnt/TotalCnt returns 0
(Count(substring(m.PTNumber,3,3)) /
(select Count(substring(m1.PTNumber,3,3))
from tblVGD1_Master m1
left join tblVGD1_ClassIII v1 on m1.SlotNum_ID = v1.SlotNum_ID
Where left(m1.PTNumber,2) = 'PT' and m1.Denom_ID <> 9
and v1.Act = 1 and m1.Active = 1 and v1.MnyPlyd <> 0
and not (v1.MnyPlyd = v1.MnyWon and v1.ActWin = 0)
and v1.[Date] between DateAdd(dd,-90,@Date) and @Date)) as AUPct
-- main select

and not (v.MnyPlyd = v.MnyWon and v.ActWin = 0)

I would like to AUTOMATICALLY count the event for the month BEFORE today
and
count the events remaining in the month (including those for today).
I can count the events remaining in the month manually with this query (today being March 20):
SELECT Count(EventID) AS [Left for Month],
FROM RECalendar
WHERE
(EventTimeBegin >= DATEADD(DAY, 1, (CONVERT(char(10), GETDATE(), 101)))
AND EventTimeBegin < DATEADD(DAY, 12, (CONVERT(char(10), GETDATE(), 101))))
Could anyone provide me with the correct syntax to count the events for the current month before today
and
to count the events remaining in the month, including today.
Thank you for your assistance in advance.

I have an sql command for when you add a new name to the database it counts to see how many of the name entered to the textbox exist in the database. If the count is 0 then it will add the name to the table. Else it displays an error message.
This works fine for inserting a new name but on my update page where you may update the name I have the same code which on button click counts to see how many exist. But if you leave the textbox the same value and click the button the count obviously results in 1 and brings up an error message.
Is there a way I can do a count but not including the name that is currently the value of the textbox?protected void UpdateSharedArea(object sender, EventArgs e)
{
SqlConnection connection = new SqlConnection(docShare_ConString);
//Count the amount of area names that are the same as typed by user
SqlCommand existCheck = new SqlCommand("SELECT COUNT(doc_area_name) FROM document_area WHERE doc_area_name = @doc_area_name", connection);
SqlParameter areaname = new SqlParameter("@doc_area_name", SqlDbType.VarChar);
areaname.Value = AreaText.Text;
existCheck.Parameters.Add(areaname);
connection.Open();
int count = (int)existCheck.ExecuteScalar();
connection.Close();
//If the area name does not exist within the table
if (count == 0)
{
//Update name Cheers, Mark

'<%# Eval("Username") %>'
Hi: Everybody
Today is not my day, I am trying to get a Count(*) from a table (name: Photos), I can get the total number if like this: WHERE (u_username = 'jamest85' )
Now, I want replace the 'jamest85' to a value from a Label, like: Label1.text or '<%# Eval("Username") %>', but always has error, so can you please check for me, how to make it right?
Thanks.
Below is the code:
<asp:Label ID="Label1" runat="server" Text='<%# Eval("Username") %>'></asp:Label> <asp:SqlDataSource ID="SqlDataSource2"runat="server" ConnectionString="<%$ ConnectionStrings:myConString %>" SelectCommand="SELECT COUNT(*) AS TotalPhotos FROM Photos WHERE (u_username = 'jamest85' ) GROUP BY u_username"></asp:SqlDataSource>
Thank you very much
jamest85

Dear SQL,
I want to count the number of records, so I tried this:
SELECT COUNT(*) AS RecordCount
FROM Categories
WHERE Active = 1
ORDER BY Show_Order ASC
But it gives me an error:
error 8126: Column name 'Categories.Show_Order' is invalid in the ORDER BY clause because it is not contained in an aggregate function and there is no GROUP BY clause.
How can I make it work ? (I must ORDER it...)
