I am trying to submit a datetime taken from a calendar into a stored procedure. I have a variable set as a datetime = calendar.selecteddate. I can print this to the page. I am getting the error "System.Data.SqlClient.SqlException: Error converting data type nvarchar to datetime.". The stored procedure is expecting @expirydate as datetime, and I am adding the date to the insertparameters as datetime. I dont have any idea why this is occuringThe date I am submitting is in dd/MM/yyyy format. I am also adding a created date into the database which is set to GetDate() in the stored procedure. This is also dd/MM/yyyy format.Does anyone have any idea why this error is occurring? It seems that any dates submitted with the day <= 12 are fine - they submit into the database
the DGV_currentactivities.CurrentRow.Cells(3).value is a datetime value that is put into a Datagridview via another stored procedure. When I run it in sql, it lists as a correct SQL datetime: 2011-04-27 05:54:51.003, in the datagridview it lists as: 27/04/2011 5:54:51
I have a stored procedure to update a table, but needs a couple of values from another table.
the first two selects get the value from the table and then are used in the update statement.
The select statments:
Select @iStatusDropDownValueID = iDropDownValueID From DropDownValue Inner Join DropDownValueType On DropDownValue.iDropDownValueTypeID =
[Code].....
First, the values that are retrieved by the first two select statements are always the same. So they could be passed in by the code itself. I don't know that this will speed things up at all, just make the entire stored procedure better and easier to read.
Second, if the "Value Name" should change this store procedure will break (which is possible, but not often).
I am looking for any insight into the Best Practices for this situation.
I want use a stored procedure in my project but I have no idea about it. Please could you tell me a little bit about how to use I can use one in my vb.net application ?
I have noticed the following but unable to understand why.Whenever a procedure is called in .net it takes more time than when it is called subsequently.Even if a procedure is called after some interval it takes more time than it takes if it is called quite frequently. i am not asking about sql query or sql command. any user definded function or user defined method takes much more time to finish when it is called occasionaly. but when the same procedure is called quite often it finishes a lot faster. why?
I am currently building an ASPX webpage for internal use. Basically, there are two buttons on this page and I need each one to kick off a different stored procedure on our local SQLServer based on the needed task. these stored rocedures do quite a bit of work and take 3-5 minutes to finish running. In neither case do I need any kind of gridview or other output from these stored procedures, as they are simply crunching/cleaning data that will populate some tables that the user will then use to complete their task. There are also no inputs or parameters needed.
So i'm OK at ASPX and pretty good at SQL, but have no idea on the VB code behind page. This is what I have ben able to put together based on 3 days of googling. i think i am close but can't quite get across the line.
CODE:
I'm not sure if you need to see any of my ASPX or my SQL. both work fine on their own, but i am not able to get these buttons to work.
Im having an issue with a Stored Procedure I have written,I can call it in management studio and it works fine, yet calling it from my codebehind gives this error The conversion of a varchar data type to a datetime data type resulted in an out-of-range value. when i call da.Fill(dt)What is really puzzling me here is that I dont actually convert anything from varchar to datetime, the most I do with the date variables is format them into a different datetime format.
My VB.Net code Private Function dbGetEvents(ByVal start As DateTime, ByVal days As Integer) As DataTable Dim dt As New DataTable()[code].....
I cant see where this error could be coming from, having tested running it in SQL management studio without error I am pretty sure the error is in the VB.My first thought was that maybe the parameter I am passing in the @start / @end values arent being recognised as DateTime so I tried adding the parameters like:
Dim p As New SqlParameter p.SqlDbType = SqlDbType.DateTime p.ParameterName = "@start"[code]....
I have a stored procedure that when I run it within my application it times out, but when I use Management Studio and pass in the same exact parameters, the stored procedure executes under a second. I had this exact same issue with the same stored procedure before, and all I did was recompile it, and it fixed the problem, but I do not want to keep having to recompile this stored procedure every few days or so. Has anyone else ran into this issue before?
Another note I would like to mention, is that I'm currently working on a test database, so I'm not inserting, deleting or updating any of the records that the Stored Procedure is using. So the database itself is not changing, but for some reason the Stored Procedure is showing degradation, and at the most we have 2 users in the database at a time.
Below is the code I use to call the Stored Procedure from my app.
As I mentioned, if I run the Stored Procedure within Mangement Studio, it runs with no problems. Also if I recompile the stored procedure, it runs fine within the app, but after a few days, the stored procedure starts to timeout again within the app and I need to recompile it again.
I am pretty new to VB and I am not sure why this is not working, basically I am trying to run a stored procedure from my web code. The sp runs just fine in SQL, I've tried it several times so I am sure that is not the problem. I don't want to return any results, I just want to see an "ok" statement if it runs and an error message if it doesn't. The code I am using for the lables (warnings and confirmation) is reused from earlier on the same page, the same goes for the validations (valUpload).
I am using SSMS 2008 and VB. I'm a novice VB developer. I am trying to display results of a simple stored proc on my ASPX page. But I get the error below. Here is my code behind for the ASPX page:
I am trying to get some data relevant to a stored procedure (or funtion) back from a database using .Net. The first thing I need to be able to do, is get the stored proc from the database and turn it into string format.The information I need is: The return set of columns, tables used within the SP, Stored Procedures called from the SP. The only way of doing this at the moment that i can think of, is though parsing the text and looking for keyword matches.
I am a newbie to vb.net and sql server. My responsibility is to build a vb.net function that when a scanner scans an object, it would take the scanned string and call a stored procedure to get a row of data that match that scanned string and pass the data row to an application that would print out a label.below is my vb.net and sql server stored procedure script
1. Do I have to come up with a public class in order to store my row of data to pass it on to a different vb.net application that would take that data row and print out a label?
2. In my stored procedure, how would I return the founded data row to the vb.net function?
Module makeLabel Public Class AMGCdata Public fileName As String[code]...........
Why I can NOT get the return value (Scope_Identity) by executing my own Stored procedure (SQL Server 2008) via this below code written in VB.NET 2008? The SP inserts the new record into Table1 but I have 0 as the return value!What's wrong with it?here is my vb.net code and my SP:
Public Function Insert(ByVal Obj As entity, connectionString As String) As Integer Dim ScopeIdentity As Integer Dim Connection As New SqlConnection(connectionString)
Where in the body of a function do you code a stored proceedure? Does the storeProceedure "spInsertVendor" replace the sql commands? Here is my code:
Private Function AddVendor(ByVal vendor As Vendor) As Integer Implements VendorService.AddVendor Dim connection As SqlConnection = PayablesConnectionFactory.GetConnection Dim insertStatement As String _ = "INSERT Vendors " _
I'm having problems trying to create a new stored procedure.I am using sql 2005 express. I also have sql server management studio express installed.I open up the studio express and goto the database that i want to use to create the stored procedure. When I right click i see a sub menu, but don't see a option that says create stored procedure ( or any option that has anything to do with stored procedures ).Am I right in saying that I need the full version of visual studio to be able to work with and create new stored procedures.I am also told that sql server comes with built in stored procedures. Am i right in assuming that I can call these without having visual studio installed. And if the answer is yes, then how do I find out the name of these procedures, the parameters they use and what each particular stored procedure does.
Dim parm1 As New SqlClient.SqlParameter("@Category_ID", txtCategory_ID.Text) Dim parm2 As New SqlClient.SqlParameter("@Category", txtCategory.Text) Dim parm3 As New SqlClient.SqlParameter("@Area_Name", txtAreaName.Text) Dim cmd As New SqlClient.SqlCommand cmd.CommandText = "dbo.udp_tblArea_ups"

i am using this code to insert data into my new table using a stored procedure now i want to delete data from the table using a delete stored procedure.
I've added few stored procedures to my SQL Server 2005 database. Few of them were a procedures containing SELECT statements and one of them contains INSERT statement. While executing the procedures with select statements are as easy as displying tables, the procedure with INSERT statement is not so easy [for me].At first, i've tried to add the procedure to the dataset and execute it as others, by filling the table adapter. But... there is now way to access the tableadapter within the code... VB does not recognise it! Just like it wasn't there! It's not even listed on with the other tableadapters below my project. It's viible only in the dataset!After few minutes i've removed the procedure from the dataset and tried to add it as a query. Everything seemed to be ok... but... after naming a function, that would execute the query.... the function is visible nowhere. I can't execute it within the code.

here willing to educate me about stored procedures, populating the datagridview, and using some bindingsource with 4 butttons, <<,<,>,>>i'm a newbie vb.net programmer willing to learn the use of stored procedures..
project, but have decided to take another direction on it, after much and continued struggling.I started out trying to use data binding, but was advised to use straight SQL statements in the code. So what I'm trying to do now: I have 2 forms, frm1 and frm2. frm1 has a combobox, which is showing all the data fine from a table, and an OK button. Upon clicking on this button, I need frm2 to load, correctly populating its textboxes and comboboxes with the corresponding data, based on the selection made on frm1. This is what I have so far:
