VB2005 Parameter Queries With SQL 2008?
Dec 7, 2009
We 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

I 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*"

Is 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?

There 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
Using cmdExe As New System.Data.SqlClient.SqlCommand
sSQL = "Delete * from mytable where UniqueID=123;Insert into mytable (UniqueID, Field) values (123, 'something')"
.CommandText = strSingleSQLLine
[Code]....
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?

I've recently ported my website from 2005 to 2008, and I'm using LINQ Queries to implement a search. The issue is that none of the fields are mandatory, so I've had to implement a dynamic LINQ Query (sic?). Here's the relevant code -
Public Function searchQuery(ByVal titleType As String, ByVal titleName As String, _
ByVal configMgr As String, ByVal lifecycle As String, _
ByVal CIType As String, ByVal recordsPerPage As String) As IEnumerable(Of

I'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.

I am new to working with SQL databases (and databases in general) so I do not have a lot of experience with how queries work and how I can practice them. When I was first learning xml and XPath, I found XPath Visualizer incredibly helpful after someone on stack overflow mentioned it to me.Due to this, I am wondering if a similar tool exists for SQL databases?Basically a tool that will allow me to connect to a database,enter queries and see somehow what the results would be like.
I have looked online a bit, however I have found relatively few options in terms of any utility that would do what I want, and that looks reliable.I will ultimately be writing an application to interact with an SQL 2008 server in vb.net, however for now I am just experimenting so I will know what I am doing when I actually want to create my application.So far I have managed to connect to the database using an OLE DB connection, but I am now looking for a way to experiement with queries without just querying and figuring out a way to interpret the results in my program. Basically I want to be able to remove the programming aspect of things so I can experiment with queries without needing to question anything in my code that is unrelated to the specific query.

Is it possible to make a procedure have a single parameter but the values for that parameter are more than one? I have this procedure:
Public Sub autoComplete(ByVal cboCombo As ComboBox)
With cboCombo
.AutoCompleteMode = AutoCompleteMode.Append[code]....
Now I was wondering if there is a way to use it like this:
autoComplete(myCombobox1, myCombobox2, myCombobox3)
Or can I use a procedure like this with 'With...End With'?

I have a method which requires a parameter to be passed in. I would like to use the Addhandler to call the method through a dynamically created button control's click event.
When I include () in the AddressOf, VS complains: 'AddressOf' operand must be the name of a method (without parentheses).
When I exclude the brackets, VS complains: Method '...' does not have a signature compatible with delegate...

One of the things that I think is really cool about VB.NET is how built-in functions and subs have extra help text in their ToolTips like "Expression: String expression to search for replace string." as well as the usual "Replace(...parameters...) as string" text. So are the pop up boxes with things like "CompareMethod.Binary" or "CompareMethod.Text." And finally I like how some functions and subs have different sets of parameters for the same routine. For example, New FileStream() starts with either a path (string) parameter or handle parameter, but none of the 15 sets of parameters contain both path and handle parameters. Is there a way that I can set up the classes and functions I write to use these things or do they only work with built in classes and functions? If there is a way, what are the proper names for them so I can look them up in the VS/VB documentation? I would be happy enough if someone would give me an example of them, but it would be nicer if I could go through the documentation and find out if there are other cool things that are related or near by.

I'm connection to a sql server 2005 database. I have a field called MapName which contains the following name for example:
SAMWON TEXTILE CO LTD
NO NOT USE
Notice the field contains an enter character.Now in my vb code I have the following
Dim SupplierCommand As New SqlCommand("SELECT OurID FROM [Mapping] WHERE (MapName=@SupplierName) AND (OrgId=" & CustomerId & ") AND (Active=1);", con)
SupplierCommand.Parameters.AddWithValue("@SupplierName", f_supplier)
'con.Open()
[code]....
where the @SupplierName parameter would be:
SAMWON TEXTILE CO LTD
NO NOT USE
exactly the same as my database field.But for some reason this query fails because of the enter characters.

I can replace one parameter with one value using string.replace, but how would I continue to process the rest of the string? Would I replace the first parameter then reevaluate the string again to find another parameter until no more parameters are found?

I have a class OrderManager, that takes a parameter of type LocalFuturesList on construction. Now.. It doesn't seem to matter if I use ByRef or ByVal here.. It still references the parent class instance of it. It also doesn't seem to matter if I type New or omit it.. Probably also because it's just an address reference. But why is it like this? And what type of objects "acts" in this way? Further I find that if I change the object in the parent class by deserializing from a file (with my method call shown), then suddenly this reference is broken in some way, so the OrderManager instance now holds Nothing I believe.If my observations are correct I see two challenges:
1. How to pass a list NOT by reference?
2. How to maintain a list reference through deserialization? [code]
