VS 2010 SQL - How To Connect Or Perform Queries
Jun 13, 2010I'm a PHP coder normally, but I've been asked to make a small vb app. I've created my sql db (MSSQL) and have got all the data in it. However, I have no idea about how to connect or perform queries.
Here's my
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[CODE]..........
1) Am I connecting properly? I created a new database using the dataset option and it has no username or password.
2) I'm trying to list the results, which will be clickable to open a new form with the full details. How would I do that?
Eg: In PHP, I'd loop through the resources using fetch_assoc, and create a link with the id and it's name as the firstname and surname.
DB/Reporting :: Perform SQL Queries On A Text Tab Delimited File
Aug 24, 2010I have a program that generates text tab-delimited files with a header row and sometimes a units row followed by data.
Example:
FirstName LastName Birthday
Michael Jordan 6/6/66
Alan Jackson 7/7/77
or
FirstName LastName Birthday
Name Name Date
Michael Jordan 6/6/66
Alan Jackson 7/7/77
I would like to be able to perform SQL queries on these files. How can I connect to a text tab delimited file to either pretend it is a database table or import it into SQL as a table, preferably through VB.NET? I could have 300,000 rows, and the fields are all numbers, not text... I have manually imported these files into SQL before using management studio, so I know it is possible but I would love to be able to do it programmatically.
Is there any way I can get the SQL code from this process because it does exactly what I need it to do but it is manual. There is an SSIS package that I saved, but I do not know what that is.
Make A .net Program Which Will Perform WMI Queries To Check For Remote Computer's Name And OS?
Jan 18, 2012I am trying to make a vb.net program which will perform WMI queries to check for remote computer's name and OS. I manage to do the first query of name using the code below..
[Code]...
I am getting error "Local variable 'query' is already declared in the current block. (BC30288)".I understand that I am using same name for the object variable for performing subsequent query. Is there a way in which I can dispose the variable completely and reuse it again for querying the new required WMI detail? My search in the net couldn't give me any clue as of how to clear the variable and use it again. The issue is with two variables "query" and "searcher". Is it only possible that I should give unique names to each query object variable as I might add more queries later on?

View 1 RepliesVB2005 Parameter Queries With SQL 2008?
Dec 7, 2009We have recently updated our SQL Server to 2008 (from 2000). I moved all the data over to the SQL 2008 server by exporting from the 2000 server. All the tables open just fine, and all the data appears to be present. Within the VB.NET app, however, any table reference that uses a parameter generates an error: The data types text and text are incompatible in the equal to operators. The table adapter works just fine with full table previews, but not with either parameters or filter values (i.e., Field1 <> '0'). I should confess that I am new to SQL 2008. What do I need to do to get these parameter queries operational?BTW, I have downloaded and installed the VB2005 plugin that enables working with SQL 2008 (VS80sp1-KB954961-X86-INTL.exe).LDC

VS 2008 Using Variables / Parameters In Sql Queries?
Sep 20, 2011I am using Visual Basic 2008 / MYSQL
Basically i have 2 tables in mysql called Data and products
The first sql query i want to do is something like this to scroll through the recordset of products and bring back information;
dbquery.commandtext = "select quantity, sku, condition from products"
But then what i want to do is bring back information from the Data table based on the sku and condition of the first sql?
so it would be something like this
subquery.commandtext = "select lowestprice from data where sku = *SKU FROM FIRST TABLE* and condition = *CONDITIONFROM FIRST TABLE*"
VS 2008 Write Database Queries On The Fly?
Jan 29, 2010Is it possible to create database queries on the fly with VB?
For i = 0 To (UBound(WeekNo) - 1)
For NLoop = 1 To 50
WeekRow(NLoop) = WeekSinceLast(i, NLoop)
Next
Next
I want to write each WeekRow to the database for each week (= i). WeekRow contains 50 elements, each of which needs to be placed in a separate field.
So, can I generate a SQL query that is constructed on the fly? If so, how do I go about it?
VS 2008 Using Parametrized Queries With Multiple SQL Statements
Jun 25, 2009There is not a VB.net database forum, and there is a HUGE difference (unfortunately) between ADO and ADO.net. I have a connection to a MS SQL database, which I understand is capable of handling multiple SQL statements in one Execution, ie

sSQL = "Delete * from mytable where UniqueID=123;Insert into mytable (UniqueID, Field) values (123, 'something')"
.CommandText = strSingleSQLLine

There are two questions here actually...can I add the parameters before setting the command text, and do I have to add the same parameter over and over again?

Jun 2, 2009I've got a couple of drop down lists for languages. I bind them to a language list that comes from a query. Then the fields are also bound to the row in the DB they relate to. I have several panels with the language drop down - each "tied" to a different table in my DB. When I call up different records on the same panel the drop downs immediately "set to the position" of that rows language in the list. But when I call up another panel - tied to another database table - I see that language in the drop down.
