I have a stored procedure that is used to create a DataDictionary for the database. Basically, the sproc generates HTML and you can then run it from Query Analyzer by Saving to a file.
What I want to do is to run this from an aspx page.
My stored proceddure "My Programs" includes a parameter @meid.How do I code an aspx file to run the procedure with a user ID, e.g. EmpID?I tried the following codes, but the error message indicated it can not findthe Stored Procedure. How do I pass the EmpID as a Stored Procedure parameter? <%meid = EmpIdcmd.CommandText = "MyPrograms meid"cmd.CommandType = CommandType.StoredProcedurecmd.Connection = sqlConnection2sqlConnection2.Open()reader3 = cmd.ExecuteReader(meid)While reader3.Read()sb.Append(reader3(i).ToString() + "......<BR> <BR /> ")End While%> TIA,Jeffrey
Hello, I have the following stored procedure and the following aspx page. I am trying to connect this aspx page to the stored procedure using the SqlDataSource. When the user enters a branch number in textbox1, the autonumber generated by the database is returned in textbox2. I am not quite sure what to do to get this to execute. Can someone provide me assistance? Will I need to use some vb.net code behind?

I have a stored procedure when query a big table about 500,000 records. When I run the stored procedure in the query analyzer, it is very fast and it only takes 2~3 seconds. However, when my aspx page try to call this stored-procedure with a Command's ExecuteReader method like bellow:
I always get timeout expired exception. I try to set the connection timeout and command timeout to 100 seconds. The exception is gone but the average execution time is about 25 seconds! While the stored-procedure only takes about 2~3 seconds in query analyzer with the same parameter.
What could be the problem?? I tried to figure this out for a couple days but still no clue.
I have a table which gets updated roughly every 6 seconds with data. I have setup an aspx page with a datagrid to meta tag refresh every 3 seconds.
Because the data sometimes stops for a couple of minutes or even hours, I was thinking of a way to update/refresh the aspx page only when the table data gets entered ( to stop page flickering every 3 seconds).
I was thinking about a stored procedure and using an on update procedure.
Does anyone have any preffered methods or suggestions on the best way to accomplish this task.
I have some SQL code as inline SQL (bad habit, I know). Now I want to convert this to an sproc, but I'm pretty much out of ideas here. The code looks like this: string SQL = "SELECT * FROM MyDBTable WHERE 1=1"; if (txtMyField1.Text != "") { SQL = SQL + " AND MyField1 = @MyField"; } if (txtMyField2.Text != "") { SQL = SQL + " AND MyField2 LIKE '%'+ @MyField2 + '%'"; } if (txtMyField3.Text != "") { SQL = SQL + " AND MyField3 LIKE '%' + @MyField3 + '%'"; } I have an search page built on ASP.NET 2.0. Based on what the user has entered to the form fields, the SQL in constructed on the fly. Since this is now inside codebehind file (aspx.cs), I want to get rid of it and move it to an sproc. But the question is how ? Some simple SQL clauses are easy to convert to an sproc but this is causing me lots of issues.
I would like to have a stored procedure to run a shared VB file, which will check a refrence value from a SQL Server table every hour, then redirect the web page to an error page if the reference value is equal to e.g. 'E'.
My question is: a S.P. can update a SQL Server table, but can a S.P. 'run' a shared VB file to redicret a web page automatically? How?

I just changed my Access 2002 database to a SQL Server ADP project. Ihad a form where the user entered a value into a text box and when acommand button on the form was clicked a Report was opened. The reportsrecord source is a query. The query uses the value from the form textbox to restrict the query.Table name = EggsTableone of the columns in the table is named: EggColorForm name = EggColorFormForm text box name = ColorTextBoxThis sql worked for the query before I converted to SQL:SELECT EggsTable.EggColorFROM EggsTableWHERE (((EggsTable.EggColor)=[Forms]![EggColorForm]![ColorTextBox]));This no longer works. Can I change the syntax somehow to get this towork? I tried dropping the brackets around the word "Forms", I trieddropping all the square brackets, etc., nothing worked.I also tried just opening the report with the report's Server Filterproperty set to:EggColor=N'Forms.EggColorForm.ColorTextBox'I tried using the Report's open event to pass the form value directlyto the report. I tried setting a variable from the text box value onthe form. So far, nothing works. Any ideas?

If I have a column named "Login" in a SQL Table (I am sharing with another application) that I am using a stored procedure to acquire the information from, how can I trranspose its name to match code already written in a Web App to get the data. There is a web app already created that has the followig code to get the data from the database Dim strSQL ast string = "UsersSelectCommand" intLoginID = objDataReader("LoginID")
My stored procedure is the following: CREATE PROCEDURE UsersSelectCommand/* ( @parameter1 datatype = default value, @parameter2 datatype OUTPUT )*/AS Select Lastname, FirstName, Login from Users Order by LastName GO The stored procedure will return "Login" instead of "LoginID" that I am wanting. How can I modify the Stored Procedure to change the LoginID to Login.
need help with my problem i have this view this code change the value field "new_unit" evry month from 1 > 2 > 3 > 4 like this evry 4 month it return to 1 >2.......... ------------------------------------------ for example
if i put unit_date = 01/05/2008 and unit=1 than new_unit=1
my question is how to create a stored procedure that move forward (all the employee) the "new_unit" field in +1 OR "unit_date" value MONTH +1
like create stored procedure name "plus" + so if i run this name stored procedure name "plus"
the stored procedure go to the viewor table and change the code view or table value
so i forward all the the "new_unit" or "unit_date" value IN one (change the cycle)+1
it doesn't matter if it change the "unit" value in the table "dbo.empList" or "unit_date" value
the important thing is that i can forward +1 or backward -1
evry time i run the stored procedure i get +1 (in the "new_unit") and olso create stored procedure name "minus" + so if i run this name stored procedure name "minus" this stored procedure that move backward the the "unit" value in the table "dbo.empList" or "unit_date" value in -1
I have a pivot transform that pivots a batch type. After the pivot, each batch type has its own row with null values for the other batch types that were pivoted. I want to group two fields and max() the remaining batch types so that the multiple rows are displayed on one row. I tried using the aggregate transform, but since the batch type field is a string, the max() function fails in the package. Is there another transform or can I use the aggragate transform another way so that the max() will work on a string?
Version: ASP.Net 2.0Language: C#Hello Everyone!I'm saving data from a function to an SQL Server 2000 db via a stored procedure. There are a few fields which are conditional and thus need not be passed to the procedure everytime. Under those circumstances I need to store null values in the fields.The problem is if I the value of the parameter as null, VS throws the error that a required parameter is not passed. I tried setting 'IsNullable' property of the parameter to true but it works for only those fields who are declared NULL in the stored procedure (For e.g. @DOB DATETIME = NULL).Strangely, this works well in classic ASP.Does anyone know how to accomplish this? Note, altering stored procedures is not an option for me.Thanks a lot!
If I have a stored proc which has 2 input variables and for example the 2nd one is null or not provided what is the best way to turn this null into a wildcard. If the second one is an int and not provided should I but a checknull statement in the proc and convert this to a wildcard %. I believe if I do I need to change the where clause "where field1 = @var " to where field1 like @var". Any input appreciated
Is it possible to call up the SubscriptionProperties.aspx page by URL for a specific report, and *specify* the parameter(s) values directly in the URL? I have a scenario where I don't want the user to have to do it.
I'm not sure if this question should be in this thread but anyway...
I have a form (Mricosoft Access front end) in which the user enter a Pending Date in one of the fields. The date is populated into my backend (SQL Server) withouht problems. Whenever the issue which had the pending date in the field is resolved I'd like to delete this date from this field and also from the back end. At the moment I'm not being able to pass the "value" Null to my back end (probably because it's a datetime type). I've searched the net throughout and I couldn't find a way around it. Only found solution to when the data is not date but numbers/letters, etc... Any ideas on how can I sort this out?

I'm trying to write a stored procedure for a search criteria. A user will have few controls on ASP.Net webpage to enter/select the search criteria, based on which , it returns the data.
A Textbox( to enter Username), A Textbox (to enter Employee name), A DropDownList (To select the profile. Its Id is sent as parameter) & A DropDownList (To select status). This is where I am stuck.
The last dropdown has 3 list items 1. --All-- value is null/empty 2. Active value is 0 3. Blocked value is 1
Though the Database table will have only 0's and 1's for the status column, the user should be able to see all records when -all-- is selected.I also tried excluding the status parameter and its condition, but no luck either way.
Hi,I have a stored procedure which expects a Null value if a user does not enter something into a TextBox. The query should return all rows if this case.The stored procedure works as expected in Query Analyzer, but my application does not seem to send a Null and no rows are returned. Any ideas?Thanks.ps I am using SqlDataSource and GridView, this is the first time I have tried to connect to a database with asp.net.
sSQL = "spBPT_Fuel_Set_Status_Approved" cmdDailyPrices.CommandText = sSQL cmdDailyPrices.Parameters.Add("@user", "Philippe") cmdDailyPrices.Parameters.Add("@verbose", "0") cmdDailyPrices.Parameters.Add("@Day_1_add", rowBand1.Cells(DayParameters.AddFactor).Value) cmdDailyPrices.Parameters.Add("@Day_1_multiply", rowBand1.Cells(DayParameters.MultiplyFactor).Value) cmdDailyPrices.Parameters.Add("@Day_2_add", "NULL") cmdDailyPrices.Parameters.Add("@Day_2_multiply", "NULL") For @Day_2_add and @Day_2_multiply parameters I want to pass the value as NULL not string "NULL" could you please let me know how to do this?
