I need the first number in uniqueidentifier sqldbtype of one of my table.i should hard-code it in my application since that one is specifial with other records and I do not want to recognize it by its name but rather it's ID.
View 1 RepliesI'm torn between using UniqueIdentifiers(UID) or some other field as my primary key for my new web app. I have two tables. I need to be able to find the UID on one record in Table1 and put that UID in a new record in Table2. I also need to be able to create a brand new UID for the new record in Table2 on the fly.
View 3 RepliesI didn't like how the SqlCommandBuilder generated it's Update command, so I'm making my own with the following code.. This is a large table and I didn't want to get a concurrency error just because I changed field A a few seconds after someone else changed field F.It works great but as you can see I manually have to exclude the Memo field because this is a TEXT datatype field and so you can't use WHERE for that.
Is there any way to get the sqlDbType for each field so I can use this procedure to easily generate all Update commands I need? I have tried GetType but that returns String for this field..
Dim strUpdates As String = "", strClause As String = "", strColumn As String
Dim dr As DataRow = dsDemo.Tables("demo").Rows(bsDemo.Position)
Dim sqlCmd As New SqlClient.SqlCommand("", frmMain.cn)
For i As Int16 = 0 To dr.ItemArray.Length - 1
strColumn = strColumn.ToString.ToLower

I am trying to convert a string values into a SqlDbType. My code is able to covert "Text" into SqlDbType.Text without any errors but when I try to convert "bit" into SqlDbType.Bit, I receive the following error: "Requested value 'bit' was not found."The same thing happens when trying to convert "int" into SqlDbType.Int Error Message: "Requested value 'int' was not found."Why will this work for "text" but not "bit" or "int"?
Dim MyType as String = "bit"
Dim sdtype As SqlDbType
sdtype = DirectCast([Enum].Parse(GetType(SqlDbType), MyType), SqlDbType)

I have a stored procedure (SQL Server Express) that returns a count of records:
SELECT COUNT(AdminUserID) AS CountEm
FROM Licenses
WHERE (AdminUserID = @AdminUserID);
Table "Licenses" has a field "CompanyID" which is a uniqueidentifier.
I need to add a clause to the WHERE to exclude records from the count where "CompanyID" is null/empty.
In VB code I'd do this with "If Not (TheCompanyID.Equals(Guid.Empty)) Then"
How would I do this in a stored procedure?
For no apparent reason, I'm getting an exception on this line in my when the table adapter attempts to fill my dataset.
Me.TblFuelTableAdapter.Fill(Me.CCFuelDataSet.tblFuel)
The error reads:
Quote:
System.ArgumentException: No mapping exists from DbType Object to a known SqlDbtype.
This error just came out-of-the-blue. If I 'Preview' the data though the DataSet directly (using the Fill() query), the data returns fine...
