Sql Server - Get Column Names From Blank Stored Procedure Data Set
Oct 31, 2011
I'm currently writing a small app that takes data provided by an SQL stored procedure and makes it available for easy export for non-tech savvy users. I'm trying to make this as generic as possible, in that you should be able to plug in just about any SP and follow my template to have an export utility. I'd like to add a way to get the column names before running the SP from the SP itself. I had assumed you could just run the SP with impossible values so nothing is returned, then get the columns from the resulting VB.NET DataTable. However, if there is no data returned, the column names aren't returned either. How can I get the column names from the SP without having to hard-code them?
I found a few examples online on how to import excel into sql via vb. but can i do it via stored procedure? Insert into SQLServerTable Select * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 'Excel 8.0;Database=D: esting.xls;HDR=YES', 'SELECT * FROM [SheetName$]')
So like, can I pass in: ('Microsoft.Jet.OLEDB.4.0', 'Excel 8.0;Database=D: esting.xls;HDR=YES', 'SELECT * FROM [SheetName$]') As a parameter to SQL Server SP?
I have a task to create a web service to receive client-side app's http request(with rpc={json data} in the end), deserilize it and put he parameter in stored Procedure in order to retrive data from sql server. the procedure query and client-side's app are already there and the return data to client-side app is JSON too
I've been looking through some of my predecessors code and in all of this data level classes, he's defined all his stored procedure names as constants at the top of the classif there's really any benefit of doing this, other than to have all the procedure names at the top of the class?
I am having some difficulty with an xPath expression. I am using an XML document to store queries / stored procedure names in an ASP application. I use a utility function to load the xmldocument (if it isn't previously loaded) and I am attempting to select the node set from the document that matches an Id element. [code] the node variable only returns the first element. I have verified the that the qry string that is used to SelectSingleNode IS the correct Id value (i.e. USER002) - however the node is getting loaded with the USER001 element. It is obviously the xPath expression that is messed up. What do I need to tweak on the xPath expression so that I can return the correct <Id> element and corresponding child <Sql> element.
I don't understand this code (listed below). this code attempts to modify the products table . It creates an update, delete and insert command. I don't understand where it gets the data values from. What I mean is that, how does it know which record to delete. there in no input box or textbox from where it can get the product ID, which would identify which record to delete.[code]...
I am using the following stored procedure to call period numbers to match them to teachers.We are writing an attendance taking application where upon selecting the teacher's name from a dropdown menu, the "period" dropdown menu populates. For some reason we are not getting the period data to populate.
Stored Procedure: ALTER PROCEDURE spGetPeriod @Period varchar(10) AS SELECT Period FROM tmTeacher
i am new to stored procedure and VB.Net, i am trying to insert a value to a column in a table in my database using VB.Net and Stored procedure Here's the procedure:
1. A user will input a value to a textbox, for example lastname.
2. When the user click the save button, the button will call the stored procedure.
I have a radgrid bound to a SqlDataSource that includes a hidden, readonly column that stores a pk. I want to pass the value bound to that column to a stored procedure for Updates but the default behavior when the column is readonly is not to pass the parameter to the sqlDataSource. My question is whether there is a way to pass that value without having to go into the code behind. Here is a snippet of my asp markup.
If I set readonly="false" on the It works fine but then the user can edit the primary key value which is not desired. I know work arounds in code behind but is there any way to do it straight in the markup?
So I want to erase the guid @value from the database and retrieve the return value from my stored procedure [code]object name 'value' not valid..Net SqlClient Data Provider0.
ALTER Procedure [dbo].[usp_validatecard]( @CLUBCARD1 nvarchar(50), @STATUS nvarchar(50))[code]....
What I am trying to do is if the clubcard parameter is found and status is active I would like the label to read 'card is good' also if the clubcard parameter is found however is inactive then the label should read 'card is good but not active' last if all those fail just have the label read 'card not in system'As of right now this code does not work I thought I could just call the stored procedure and exec it and it would print the statements depending on what passes however it is erroring out. When I debug it the error I get is under the cmd.parameters.add is
Item In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user.
I want to execute a sql server stored procedure in vb using a button. The stored procedure as one variable that is read from a text file.I got it to read the variable from the text file but don't know how to execute the stored procedure.
This is my Stored Procedure Code to get the customer mobile value:[code]I was try to get this value into lblGetCustMobile (Label Control) using this [code]but nothing happened, can any one make this code get the mobile NO. into lblGetCustMobile?
I am using vs 2008 doing a winforms app in vb.net. I have a database with a single table, that has two columns, in it and a stored procedure. The stored procedure is supposed to take an input value, match that value against one column in the table and then return the corresponding value from the other column; except it doesnt.It returns 1 or 0
ALTER PROCEDURE dbo.getgamenumber(@outputnumber bigint OUTPUT, @inputnumber bigint) AS
This is a bit old-contents to be discussed but I need someone who can explain me how to create stored procedure in SQL Server for returning a value from procedure, example:[code]Then I need the name of its customer and the address instead.I need to make it as a stored procedure and show me how to execute it on VB.NET. Perhaps we assume that the name will be prompted to LABEL1.TEXT and the address will be prompted to LABEL2.TEXT. I've improved this SQL-Server Stored Procedure Using return but I have nothing to return after I execute it.[code]
I have a DataGridView which populates from an SQL query just fine in default mode
using these table names [firstName] [varchar](20) NOT NULL, [lastName] [varchar](20) NOT NULL,
[code]....
I have edited the column headers and set the column names to the same values as my table names yet the data is not showing in form load I have set datagridview.AutoGenerateColumns = False I know the data is there if I delete datagridview.AutoGenerateColumns = False then the data is shown with the default headings?
Created an XSD file that represents my table structure from my database. Created a class file to hold my functions such as the one below.
Code sample:
Public Function GetUser(ByVal UserID As String) As xsdUser.UserDataTable Dim SqlConn As New SqlConnection(ConfigurationManager.ConnectionStrings("MyDatabase").ConnectionString)
[Code]....
Now it seems odd to me to have two files doing what should be contained within just one file. I feel like I should have one class file called "User" and have member variables in there along with the class functions like the one above. But all the tutorials I see are using these data tables. On top of that I'm not sure how to handle the if statement at the end of the function. I don't think I would want to return a whole DataTable since I should only have one row, and I also don't know how I would handle an error if my function is supposed to return a data table. I suppose I could return an empty one and then if the table is empty in my code then I would handle it there, but this also seems messy.
Is this the common way of retrieving information from a stored procedure? Or is there a more up-to-date method that I'm not seeing in my search results?
I have a problem trying to link my my datagrid view to my sql server stored procedure. The way it should work is that when I select an item in a list from my combo box it returns a set of rows on the datagrid view specific only to that item This is the code on the server sideCREATE PROCEDURE spCompanySearch
[Code]...
The @comp is supposed to be each item in the combobox list but I don't know how to do it or how to go about it
I have a small question about stored procedures and the DateTime2 datatype in SQL Server 2008.
I got several stored procedures using the DateTime2 datatype and I want to insert the date 0001.01.01 00:00:00 but this won't work with VB.net and I cannot find the reason why.
I use this code fragment:
Dim sqlStatement As New SqlClient.SqlCommand Dim sqlTransaction As SqlClient.SqlTransaction sqlStatement.CommandType = CommandType.StoredProcedure
[Code]....
to call the stored procedures from my program (the stored procedure is a simple INSERT statement nothing else and works fine with actual dates). But when I enter the date 0001.01.01 00:00:00 it always comes up with the error that I cannot insert dates before '01.01.1753' when I want to execute the stored procedure.
Now I already know that the DateTime2 datatype in SQL Server should support this.
So my question is it possible that this is a driver problem and updating the SQLClient would solve this, or is this a general problem and I can finally stop searching and just use 1753.01.01.
I have an application that I'm building which pulls dates from a database. The start value is stored as payPeriodStart date and I add 7 days to get the end date. What I need to know is, is it possible to store those values and pass them to a Stored Procedure? Currently my stored procedures have "static" dates in them ie[code]...
this is the first time i am calling a stored procedure via vb.net and i would like to make sure i have everything correct before i execute it. This is my code:
[Code]...
The stored procedure returns 6 colums worth of data and i would like to add that data to a listview. I'm not sure i have the correct sytax for doing that but this is what i used in my previous sql code (running a query with, not a stored procedure). Also, i'm not sure how to go about getting data for the @xxx names above from a textbox? How do i pass the values into the @xxx names from the users textbox? The MS SQL mangement studio code is this for the the stored procedure:
In order to fill a datagridview according to the selectedvalue of a combobox I've tried creating a stored procedure. However, as I'm not 100% sure what I'm doing, depending on the WHERE statement at the end of my stored procedure, it either returns everything within the table or nothing at all.This is what's in my class:
Public Function GetAankoopDetails(ByRef DisplayMember As String, ByRef ValueMember As String) As DataTable DisplayMember = "AankoopDetailsID" ValueMember = "AankoopDetailsID"[code]....
guess it's down to the WHERE part of the stored procedure, but I need a way to pass the selectedvalue of the combobox into the @AankoopID parameter.
I've got a conversion utility that basically copies values from one table to another. It's worked great for a while, but I've run into a strange issue with one customer. They got through 1.5 million records with the utility but now it is completely halted.When calling a stored procedure from VB.Net, it just hangs until the SqlCommand times out.Calling the same sproc from Management Studio executes instantly. My VB.Net code for the SqlCommand is below (insertConn is defined and opened earlier, dr is a SqlDataReader that has been populated in a previous step from completely different SqlConnection and SqlCommand instances):
Dim conn As New SqlConnection("connection string here") Dim insertConn As New SqlConnection("connection string here") Dim dr As SqlDataReader = Nothing
I know there are the 'Wizards' to help me, but I need the code to access the Table Manager, the data set and so on, create them in my project and access the tables or stored procedures
I have sql server2000 encypted stored procedure. I can not modify them. Typicaly all the procedures manipulate row by row different tables using cursors etc. When the stored procedure is executed at the Query Analyser screen, I see error being thrown in between but the procedures continues till all the records have been processed. This behavior is acceptable to the client. I now need to automate the process using VB.net 2002 windows application. I call the procedure from vb.net but the program throws runtime error on the 1st occurance of a error in the stored procedure.
