Shared Function And Mysql Stored Procedure?
May 11, 2012
i created a dll file using vb.net then it has a shared function that will execute a stored procedure of mysql but my code is something long and when accessing it, it has a big risk that it can produce an error if there is an incorrect string input, i am asking an advice how i can make it much better or can point me something much better than my code as my reference.here is my codefirst i created a function named mysqlParamDatatype wiith 1 parameter, this function will detect the mysqldatatype of the mysql sproc parameter so it can pass the value with the correct datatype. but it is to long.
Shared Function mysqlParamDataType(ByVal i As Integer) As MySqlDbType
If i = 1 Then
Return MySqlDbType.Binary
[code].....

How do I create a stored procedure for mysql using VB .NET programmatically?
EDIT: I have tried using ExecuteNonQuery provided by MySQL .NET Connector. It prompts me error. Maybe it's because I put "Delimiter $$"? I know I can create using script (batch file) if I want to send it to my client (as commented below). But my objective is to keep MySQL password safe. So script is not the way.

I've been trying to figure out how to call an Oracle 10g stored function and insert the return value into my VB.NET application. Stored procedures I've been already able to figure out, but I have no idea about functions.I have the parameter set to send to the function, the oracle function works perfect, but what VB coding to I need to get that return value. The return value is a CHAR.
Again the Oracle DB is in their 10g release.
My version of VB.NET Is Visual Studio 2010.
Also I've beent trying to use the Imports System.Data.OracleClient namespace but it comes up with an error saying its not available. Right now I use System.Data.OleDb. How can I import the oracleclient?

My problem is this (apologies if this is a little long ... hang in there):I can define a function in VB.NET with optional parameters that wraps a SQL procedure:
Sub Test(OptionalByVal Arg1 As Integer _
Optional ByVal Arg2 As Integer _
Optional ByVal Arg3 As Integer

USE [UCSMIS]
GO
SET ANSI_NULLS ON
[Code].....
When I try to add it to my report it gives an error, is it because of the temp table and how should I go about it?

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 would love to use the following procedure to set the Title, keywords etc. of my pages, in a module.
Public Shared Sub SetTitle(ByVal Heading As String, ByVal Keywords As String())
Dim myMaster As Masterpage = DirectCast(Me.Master, Masterpage)
If Request.QueryString("lng") = "es" Then
[Code]....
The problem is that i get two errors.
At Me.Master i get the 'Me' is valid only within an instance method. error and at
If Request... i get the error
Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.
So how do i fix these? I would like to have that procedure in a common place and not in every page.

I'm working on a web application that stores some Office document (and any other kind of doc) on a remote shared area. I need to allow user to view the files available on shared area using my web application, how can I do that? Some years ago I solved this issue with Java / JSP opening into an output streaming the file, how can I do the same with ASP.NET and VB.NET?
This is how I organized my application:
C:Webapp -> Webapplication
emoteserversharedfolder -> shared area
The owner of IIS process is the only user that can write / read the shared area.

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.

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.
cmd.CommandText = "sp__RECAP_SELECTION_GET_GRID_RECORDS_RECAP_TYPES"
cmd.Parameters.Add("@FK_KitchenID", SqlDbType.SmallInt).Value = cmbKitchenCustomer.KitchenID_SelectedPrimaryKey
[Code]....
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 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]...........

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.
