SQL Query - Operator & Is Not Defined By Type GUID
Apr 20, 2011I've got a problem in one of my SQL queries, the type GUID can't be used with the operator & (obviously from the title). Here's the few lines of code which I'm using:
Dim ClientsAssetID As Guid = New Guid(ClientsAssetIDTextBox.Text)
Dim Client1 As Guid = New Guid(Client1TextBox.Text)
Dim Client2 As Guid = New Guid(Client2TextBox.Text)
[code]....
ClientsAsset, Client1, Client2 and Client3 are all of type GUID, but are entered into the textboxes as strings, are converted to guid and then should all go smoothly into the query, but it's having a problem with linking everything together. The error I'm
getting is "Operator '&' is not defined for types 'String' and 'System.Guid'.How do I fix this? I've tried a few different things, such as using Ctype in the query, but they have also circled back to this error.

View 1 RepliesLINQ To SQL: Unable To Cast Object Of Type 'System.Guid' To Type 'System.String'
Nov 15, 2011I am getting a really bizarre error and it makes no sense at all.Basically I have a user entity which has a Password property. This property is of Type Binary, the server data type being Binary(512).I am reading this value in and converting it to a byte array. However whenever I run my code I am getting a completely unrelated error of Unable to cast object of type 'System.Guid' to type 'System.String'.This strikes me as very odd since I am not using a property or variable of type string or GUID anywhere in this procedure where it falls over.
The code is below:
Public Shared Function ValidateUser(ByVal username As String, ByVal password As String) As UserValidationMessage
Using db As New EntityMapDataContext
Dim u = From user In db.Users

View 1 RepliesGUID - Unable To Cast Object Of Type
Dec 16, 2009I want to do something like this:
Dim selectedCourses As List(Of Guid) =
From item In chkListCourses.Items Where item.Selected =
True Select item.Value
But I get the error:
Unable to cast object of type
'WhereSelectEnumerableIterator2[System.Object,System.Object]'
to type
'System.Collections.Generic.List1[System.Guid]'.
The value of item is a string representation of a Guid. I'd also like the syntax for a Lambda expression.
Reflection - .NET: Checking If Variable Is Of Guid (nullable) Type?
Jan 16, 2012I'm trying to check if a variable has been defined as a nullable Guid. eg.
Dim myGuid As Nullable(Of Guid) or Dim myGuid As Guid?
It seems doing a myGuid.GetType returns the underlying type, that is type Guid, not Guid?. So testing myGuid.GetType Is GetType(Guid?) always returns False.How do I find out if myGuid is a nullable type?
Ed: I can do the following, which correctly returns True for "Guid?" and False for "Guid":
Not Nullable.GetUnderlyingType(GetType(Guid?)) Is Nothing
The problem is that I don't know how to retrieve the nullable type from the variable itself, in order to test it. I've only been able to get the underlying (non-nullable) system type.
I've written a db helper function. I pass it an object comprised of public members, representing the row data of a table. The members are the table columns.Using reflection, I loop through these public members to create an INSERT statement for a command object and populate its parameters with the values in those members. So far so good.But now there's a table which has a uniqueidentifier column which I must not populate from the row object, as it defaults to "NEWID()" (using SQL Server 2008). Instead of skipping all Guid columns, which would be easy, I only want to skip ones defined in the row data class as "Guid" (non-nullable).Basically, I'm using the Guid? (Nullable) type to indicate it's ok to populate that uniqueidentifier column with data. If it's non-nullable, that tells me to skip it because the column has a NEWID() default value.

Check that the type definition is accessible to the reference. For example, if the type is in another module and has been declared Private, move the type definition to the referencing module or declare it Public.If the type is defined, but the object library or type library in which it is defined is not registered in Visual Basic, click Add Reference on the Project menu, and then select the appropriate object library or type library.
