Sql - Simple Select Statement When Member Is Involved?
Dec 5, 2011
Using an OLEDB connection I want to do a select statement but for the table I am selecting from, a table member also has to be there too which seems to be messing up my results. Normally I would write to get the column "col1":
SELECT lib1.table.col1 FROM lib1.table
For the table I need the information from, the table has a "submember". From what I have gathered the syntax is something like this:
SELECT lib1.table(submember).col1 FROM lib1.table(submember)
The problem is that the results are giving me every column within the table, not just my "col1" data.
The .ColorReportedDate, .ColorTypeKey, .IsColorKeyNull, etc are from my strongly typed dataset row. If .IsColorKeyNull Then .ColorReportedDate = Now() ElseIf cboColorType.SelectedValue <> .ColorTypeKey Then .ColorReportedDate = Now() End If
I want to put it (the select count statement) in this LINQ statement so I can get the sales count in my linq statement: Dim TheLeads = (From L In DB.Leads Where L.IsDeleted = False Select L).ToList() Is this possible to do in LINQ?

I have a combo box that is populated with a list of objects (corresponding to all employee rows from a database that meet the criteria IsTech). These are not entity objects though, I have created my own class that stores the member values of each row from the DB. I have set the DisplayMemberPath to EmployeeId so the Combo box display the EmployeeId ( an integer ) member of my object. Ie. right now there are only 2 IsTech employees in my DB so the combobox displays the numbers 3 and 8 ( their EmployeeIDs).

I would like to know what are the basic steps involved in setting up your application to able to read data from another application. Then take that data and modify it and send it back to the application. The data being read will have over 100 fields.... what is the most efficent way to store them? Put them in a class object?

I am tryin to access a 2003 Microsoft Access Database using VB in an OleDb format. The database file name is Billings.mdb and there are 3 tables in the file the one I am trying to access is tbl Clients. When debugging the program I continue to get an Unhandled error point to the FROM part of the SELECT statement. It continues to occur regardless of my attempts to vary the input.
In the program my connection statement is as follows:
Dim connectionString As String = "Provider = Microsoft.Jet.OleDb.4.0; Data Source = C:Documents and SettingsTrialsBillings.mdb"
The Select statement is as follows:
Dim selectStatement As String = "SELECT ID, ..., PB " & "FROM tbl_Clients " & "WHERE ID = ?sngID"

I am using vb.net 2005. I am trying to select data from a table where the field [hoteldate] is 2 days from now. The field's format is MM/dd/YYYY and when I use the Where clause :WHERE HOTELDATE = DATEADD([DAY], 2, GETDATE()) it returns nothing.
