Where Do I Declare SQL Connection Variable In My Application
Sep 27, 2007
In my asp.net application , I have to open/close SQL databse connection many time, and I dont want to declare Following variable everytime I open SQL database connection
Dim cntec As New SqlClient.SqlConnection(cnStrtec)
Dim datec As New SqlClient.SqlDataAdapter
Dim dstec As New DataSet
Dim cmdtec As New SqlClient.SqlCommand
so do I decalre above variable in module.vb as Public variable or is there any other way to do this.

In a previous life, for each variable that we passed into a query, we would set -1 to the default for all so that when we converted it to an SP, we could query a specific dataset or or all. The following is a sample bit of code, I can not for the life of me remember how to pull back all using -1.
The following is the code that I currently have, it's a simplified version of the total SP that I am trying to use, but enough to give you the idea of what I am trying to do.
The MemberId field is a varchar(20) in the table.
Create procedure sp_GetClaims_BY_MemberID @Memberid varchar (50) as Select top 100 * from [QICC-TEST].dbo.tblClaims_eligible where Membid = @memberid
EXEC sp_GetClaims_BY_MemberID '99999999999'
The above SP works fine, I just need to be able to modify it so that I can pull back all records for all member id's, any suggestions?
Must declare the scalar variable "@Id_CostEmployee".
I'm tired of "googling" this error, and I've tried all the advices, nothing... I don't know what is happening here, I have 5 other forms, all simillar and they all work!
I'm making an ecommerce web app from following the Apress "Beginning ASP.Net 2 E-commerce with C#" book, and when I implement a stored procedure (I made a mdf DB in the app_Data folder), I get the following message: Must declare the scalar variable @CategoryIDThe code used to obtain this error is below: CREATE PROCEDURE DeleteCategory(@CategoryINT int)ASDELETE FROM CategoryWHERE CategoryID = @CategoryID I get this error with every Stored Procedure I try to implement. What should I do to fix this? In SQL Server 2k5 Management Studio, this problem does not present itself.
Hi with the code below I am getting the error Error inserting record. Must declare the scalar variable "@contractWHERE" I removed @contract and it then gave me the error Error inserting record. Must declare the scalar variable "@zipWHERE" I was wondering if some can point me in the right direction for fixxing this protected void cmdUpDate_Click(Object sender, EventArgs e) { //Define ADO.NET Objects. string updateSQL; updateSQL = "UPDATE Authors SET "; updateSQL += "au_id=@au_id, au_fname=@au_fname, au_lname=@au_lname, "; updateSQL += "phone=@phone, address=@address, city=@city,state=@state, "; updateSQL += "zip=@zip, contract=@contract"; updateSQL += "WHERE au_id@au_id_original"; SqlConnection con = new SqlConnection(connectionString); SqlCommand cmd = new SqlCommand(updateSQL, con); //Add the parameters. cmd.Parameters.AddWithValue("@au_id", txtID.Text); cmd.Parameters.AddWithValue("@au_fname", txtFirstName.Text); cmd.Parameters.AddWithValue("@au_lname", txtLastName.Text); cmd.Parameters.AddWithValue("@phone", txtPhone.Text); cmd.Parameters.AddWithValue("@address", txtAddress.Text); cmd.Parameters.AddWithValue("@city", txtCity.Text); cmd.Parameters.AddWithValue("@state", txtState.Text); cmd.Parameters.AddWithValue("@zip", txtZip.Text); cmd.Parameters.AddWithValue("@contract", Convert.ToInt16(chkContract.Checked)); cmd.Parameters.AddWithValue("au_id_original", lstAuthor.SelectedItem.Value); //Try to open the database and execute the update try { con.Open(); int updated = cmd.ExecuteNonQuery(); lblStatus.Text = updated.ToString() + " records inserted."; } catch (Exception err) { lblStatus.Text = "Error inserting record. "; lblStatus.Text += err.Message; } finally { con.Close(); } } }
OK i have my stored procedure all set up and working.. But when i try and add a second variable called @iuser and then after i execute the stored procedure, i get an error saying:- ERROR "Must declare scalar variable @iuser"
Here is the code i am using in my stored proc, also my stored proc worked fine before i used a second variable??!
//BEGIN
ALTER PROCEDURE [dbo].[putpending] (@cuuser nvarchar(1000), @iuser nvarchar(1000))
And i know my VB.NET code is working but i will put it in anyway:-
//BEGIN
'variables Dim user As String user = Profile.UserName Dim intenduser As String intenduser = DetailsView1.Rows(0).Cells(1).Text.ToString()
'connection settings Dim cs As String cs = "Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|friends.mdf;Integrated Security=True;User Instance=True" Dim scn As New SqlConnection(cs) 'parameters Dim cmd As New SqlCommand("putpending", scn) cmd.CommandType = CommandType.StoredProcedure cmd.Parameters.Add("@cuuser", SqlDbType.NVarChar, 1000) cmd.Parameters("@cuuser").Value = user cmd.Parameters.Add("@iuser", SqlDbType.NVarChar, 1000) cmd.Parameters("@iuser").Value = intenduser 'execute scn.Open()
I have the following SP, which gives out a "Error 137: Must declare variable @tmp_return_tbl" error.
This is the important part of the code: . . . -- DECLARE TABLE VARIABLE DECLARE @tmp_return_tbl TABLE (tID int, Text_Title nvarchar(30), Text_Body nvarchar(100))
-- fill out table variable USING A SELECT FROM ANOTHER TABLE VARIABLE -- NO PROBLEM HERE INSERT INTO @tmp_return_tbl SELECT TOP 1 * FROM @tmp_tbl ORDER BY NEWID()
-- TRYING TO UPDATE A TABLE UPDATE xTable SET xTable.fieldY = xTable.fieldY + 1 WHERE xTable.tID = @tmp_return_tbl.tID --THIS PRODUCES THE ERROR . . .
I know I cannot use a table variable in a JOIN without using an Alias, or use it directly in dynamic SQL (different scope) - but is this the problem here? What am I doing wrong?
I am declaring a variable to hold a string to be used in my script. The contents of the variable looks perfect and works independently, the variable it does not work. (BTW, do you call this a variable in T-SQL too?). The idea is to pass the value to the script to generate different results sets.
//Parameter DECLARE @Codes varchar(8000); SET @Codes = '''07-1110_CHA,1'',''07-1110_DCV,2''';
Following stored proc uses dynamic sql but it gives the error Msg 137, Level 15, State 2, Line 3 Must declare the scalar variable "@ProjectBenefitID". though its declared .please. tell the workaround

I'm attempting to modify some Crosstab generating code, and I need someadvice/examples.Currently, the code uses a single string variable to store thedynamically generated query (www.johnmacintyre.ca). The problem is thatI am trying to pivot biological taxonomy information, and may end upwith a table containing over 200 columns. This takes the dynamic stringwell over the 8000char limit for variables.[color=blue]>From my understanding, the EXEC() command does not have the 8000char[/color]limit if the execution string is broken into chunks, and concatenatede.g. EXEC(sql1 + sql2 + sql3 + ...). So the solution I think I need isto:1) start a counter at the beginining of the dynamic generation2) append the counter value to the end of a string variable name3) DECLARE the new variable and attach that loop cycle of text to it,or attach each chunk of characters < 80004) build the EXEC() string by concatenating each dynamic varibleCan this be done? Should it be done? Is there a better way to addressthis type of problem?Thanks for any ideas or insightsTim Pascoe

I’m having trouble with a datalist. The default view is the Item Template which has an Edit button. When I click the Edit button, I run the following code (for the EditCommand of the Datalist):
It errors out with the message “Must declare variable @ID�.
I’ve used this process on other pages without problem.
The primary key for the recordsource that populates this datalist is a field named “AutoID�. There is another field named ID that ties these records to a master table. The list of rows returned in the datalist is based off the ID field matching a value in a dropdown list on the page (outside of the datalist). So my SQLdatasource has a parameter to match the ID field to @ID. For some reason, it's not finding it and I cannot determine why. I haven't had this issue on other pages.
Here’s my markup of the SQLDataSource and the Datalist/Edit Template:
Hi,Can somone please tell me why I get the error 'Must declare the scalar variable "@recCount".' when I execute this Store Procedure? ALTER PROCEDURE dbo.CountTEst AS SET NOCOUNT ON DECLARE @sql as nvarchar(100); DECLARE @recCount as int SET @SQL = 'SELECT @recCount = COUNT(*) FROM Pool' exec sp_executesql @SQL RETURN @recCount In this case I expect RETURN value = 4.I've tried various approaches, including adding an OUTPUT parameter to the exec statement, but just can't get the syntax correct. Thanks
I am not seeing the problem with this. I have a button at the bottom of this form that does this... protected void Button1_Click(object sender, EventArgs e) { SqlDataSource1.Insert(); } And the SqlDataSource code...<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:calldbConnectionString2 %>"

All I want to do is run the sql server script located at http://www.data-miners.com/sql_companion.htm#downloads.
This creates some tables and uploads a series of text files into them.
When I run the script through SQL Server Express 2005 I get the error Must declare the scalar variable "@DATADIR". I suspect it's something with me putting in the wrong path.
The text files that the script needs to load into the table are located on the K drive, and I have changed the path in
declare @DATADIR varchar(128) set @DATADIR='C:gordonookdatafinal extfiles'
to
declare @DATADIR varchar(128) set @DATADIR='k: extfiles'
I suspect this is the wrong syntax that's why it's not working but I might be totally wrong.
The text file and the server are both saved on the k drive.
In my SQL Server Management Studio Express, I have a Database "testDb" that has a dbo.Inventory with a column "quantity". I executed the following sql script:
USE testDb
GO
CREATE FUNCTION AverageQuantity(@funcType varchar(20))
RETURNS numeric AS
BEGIN
DECLARE @average numeric
SELECT @average = AVG(quantity) FROM Inventory WHERE type=@funcType
RETURN @averge
END
GO
I got the following error message:
Msg 137, Level 15, State 2, Procedure AverageQuantity, Line 6
Must declare the scalar variable "@averge".
I think it was declared already in the BEGIN - END block. Please tell me why I got this error and advise me how to fix this problem.

I'm attempting to create my first login form using the CreateUserWizard. I've spent this week reading up on how to create and customizing it. I want it to 1) the required user name is an email address (which seems to be working fine) and 2) having extra information inserted into a separate customized table. I now have the form working to the point where it accepts an email address for the username and it then writes that information along with the password to the aspnetdb.mdf...but i can't get the rest of the information to write to my custom table.I am getting the error "Must declare the scalara variable "@UserName" here's my .cs code:public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) {

Hi all can you help me, I know that I am doing some thing wrong. What I need to do is set a variable to the current date so I can use it in a SQL query to an access database. This is what I have so far <script runat="server""> Sub Page_Load dim --all the variables for my sql connections-- dim ff1 As Date then my sql connection and queries sql="SELECT FullRate, " & ff1 &" FROM table1 WHERE hotelnumber = " & hotel This works is I set ff1 as a string and specify the string (my column headings are set as dates in my table) dim ff1 As string ff1="30/01/2006" but I need ff1 to be the current date and is I use ff1 As date it returns time and date Is there any way to set ff1 to the current date in this format "dd/mm/yyyy"
Hi, I'm a complete newbie to SQLServer and t-sql generally. What I want to do is create a new variable in a stored procedure based upon the value of another variable.
eg in the loop below I want to create 10 new variables, called @var0,@var1,@var2 ...@var9
declare @varname nvarchar(10) declare @i integer
select @i=0
while @i<10 begin set @varname = cast(('@var'+cast(@i as char)) as nvarchar(10)) set @i=@i+1 end
DECLARE @SOPCursor AS CURSOR; SET @SOPCursor = CURSOR FOR
[Code] ....
The @Table_Name variable is declared, If I replace the delete statement (DELETE FROM @Table_Name ) with (PRINT @table_name) it works and print the table names.
