Number Of Query Values And Destination Fields Are Not Same
May 9, 2011I am getting the above error in my code. I've searched the net (on this site and others) for a solution to this problem and it seems that its either something to do with a field name being a reserved name ie. Date, Time etc.... or its missing (') or (") in the SQL command. ive tried both these solutions to no avail.

Executing A Sql Command - Number Of Values Provided Must Be Equal To The Number Of Placeholders In Query?
Aug 11, 2010I have a problem with a sql query. Through the query I am trying to search database for any occurrences of string (can be anything) in a column using the SQL LIKE command. The problem is that it works fine for most of the strings say john, jim, ji"m , but does not work when i include the following characters which are ( ' , { , } , and a single quotation mark). MYSQL query takes care of these special cases by putting them in [] block whenever user enters them .But i am getting the following error when i go to query the database using the GetSelectCommand() in VB.NET
Exception Details: System.ApplicationException: Number of values provided must be equal to the number of placeholders in query.I have checked the query over and over again .. but its fine .My database server is Sql Server 2008.So my application throws the exception in this command:
Using reader As MustDisposeDataReader = _
pmSystem.DatabaseManager.GetSelectCommand(selectStatementBuilder.ToString(), New Object() {})
Where MustDisposeDataReader is an instance of a class in an internally developed library, which inherits from System.Object. pmSystem is an instance of the class PlanManagerSystem which implements the commandlayer. GetSelectCommand() takes the select command
.net - Write A Linq To Sql Query To Find Records Where Field Name Can Match One Of Dynamic Number Of Strings?
Mar 21, 2012I have users check off lab facilities in a UI. I want to use linq to fetch corresponding records for all of the labs that they have checked off. Basically,
Dim myRecs = (From l As EpiData In myDataContext.EPIDatas Where l.facility= _
one of the checked labs
So basically, I need to write a linq query where the "strings" to match are determined at runtime. Is there any way to do this easily? I know that there is a library out there called dynamic LINQ, but (1) it's in C# and I'm writing in VB (2) I'm really just looking for a single, simple solution for this single case.

Blob Field In Query String
Feb 25, 2010I had been using this way for while, and it seems it work fine with char and numbers.
Dim MyVar1 as String = "Hello"
Dim MyVar2 as Integer = 1
Dim MySQL = "Select * from table where field1 = '<field1>' and Field2 = <field2>"
MySQL = MySQL.Replace("<field1>",MyVar1).Replace("<field2>",MyVar2)
msgbox(MySQL)
But, when I have to deal with blob field, where I store "wav file" for example, I had to read it as array of bytes, and the only way I find to insert the array of bytes in my query string is by using the command.AddParameter
Dim myfile As System.IO.FileStream = System.IO.File.OpenRead("full_wav_file_path")
Dim myArray(myfile.Length) As Byte
myfile.Read(myArray, 0, (myfile.Length))
[Code] .....
Is there another way to insert it without addParameter?

Passing Query And Field Parameters To A Sub?
Feb 8, 2010I have a LINQ query:
VB
Dim Db = New MyDataContext
Dim Qry = From cust in Db.Customers
Select cust.ID, cust.Name
And I want to pass it to a function to filter it, like this:
VB
FilterAnyQuery(Qry, cust.ID) ' WHERE "cust.ID" CAN BE ANY FIELD
The Sub should be of this kind:
VB
Sub FilterAnyQuery(ByVal AnyQry As iQueryable, AnyField as ???)
AnyQry = AnyQry.Where(AnyField = "somevalue")
End Sub
How can I pass "AnyField" to the Sub and make the LINQ "Where" clause work?

Nov 12, 2009I have a problem with the Validation of a Integer-Field in my application.Its an Access DB on a Windows Form.I implemented the validation in DataSet.vb using an ErrorProvider on my Form.The field name is FNr and should not accept duplicate numbers.If the field value is changed, a query checks if the number already exists in the Datatable and if so it sets the error on that field.If the user tries to change the field to a number which is a duplicate I want to cancel the input back to the original number. This works but the

Auto-assign Number To SQL Field?
Jan 12, 2010Probably a simple question for most of you. I'm putting members of a group into a SQL Database so we can better manage attendance and 'points' that they earn for doing work. I've written the program in VB and have the SQL server running fine. However, I have created a separate table to handle the points and have marked the relationship between the table - the column is named 'PointID', and should be unique for each person. When I add a new user to the database, I want it to automatically assign a value to that without me having to do anything extra beyond pressing save. From this PointID, it should identify the user and it will bring up the person's points.
