View 1 RepliesVS 2008 DataGridView - DataSet With 2 Tables And Relationship
Jul 2, 2010I'm going to describe this as simple as possible, and it a typical setup for a database...
I have 1 DataSet, 2 DataGridViews (DGV), and 2 BindingSources (BS).
The DataSet has 2 tables and 1 Relationship (FK).
Table 1 is a employee table
Table 2 is timeclock data.
Both tables contain a column: EmployeeId
FK is linked to EmployeeId of both tables.
DGV1 has it's datasource=BS1
BS1 has it's datasource=DataSet and it's DataMember=Table 1.
Thus DGV1 shows Table 1.
DGV2 has it's datasource=BS2
BS2 has it's datasource=BS1 and it's DataMember=FK
Thus DGV2 shows Table 2 filtered by what's selected in DGV1.
Now when I use the mouse or keyboard to select a cell in DGV1, the relationship causes DGV2 to update to only show data from Table 2 where the EmployeeId row equals that from the selection in Table 1. With me so far?
Well all that works great. But what if I need to programmatically select a row in Table 1 to cause Table 2 to update? I've tried everything I can think of, but Table 2 NEVER updates when I attempt to programmatically select a row or cell in Table 1.

View 4 RepliesLINQ To SQL And Join Two Tables With OR Clause
Apr 23, 2009Let's say I have Plans and Documents
Dim myPlans = _context.Plans.Where(predicate1)
Dim myDocuments = _context.Documents.Where(predicate2)
I have structured the where clause for each using PredicateBuilder. So, myPlans and myDocuments have a correct SQL statement. What I'd like to do is join these two tables into one linq statement. The problem I'm having is that, by default the AND condition is joining the where clauses.
myPlans Where clause : (p.name like "%test%" AND p.name like "%bed%") OR (p.description like "%test%" AND p.description like "%bed%")
myDocuments Where clause : (d.name like "%test%" AND d.name like "%bed%") OR (d.description like "%test%" AND d.description like "%bed%")
When I combine the two the desired result Where clause is:
Where (d.ID = p.ID) AND
(myplans where clause above) OR (mydocument where clause above). Meaning, I'd like the two where clauses in each of the tables to be "or" instead of "And".
The current result where clause is:
Where (d.ID = p.ID) AND
(myplans where clause above) AND (mydocument where clause above). Meaning, I'd like the two where clauses in each of the tables to be "or" instead of "And".
I'm forming the statement like this:
Dim test = From d in myDocuments _
Join p in MyPlans on d.ID Equals p.ID _
Select d.Name, p.Name

Can't Use A Where Clause On Both Tables In A LINQ Group Join?
Jun 7, 2011Here's what I want to do:
Dim queryX = From m In db.Master
Where m.Field = value
Group Join d In db.Detail
On m.Id Equals d.MasterId Into Group
Where d.Field = value
In English, I want to join the master and detail tables, specifying conditions on each. But this causes the following compiler error:
"Name 'd' is either not declared or not in the current scope."
It works if I put this same condition in functional form:
Group Join d In db.Detail.Where(Function(x) x.Field = value)
but I think this is more typing, harder to understand, and introduces that irritating dummy variable. I really would prefer to use the query comprehension syntax. Is there a way to accomplish this?

Join Lists Or Arrays Like Outer Joining Tables In SQL?
Jun 27, 2011Basically what I'm having to do is create a program that takes a list of CaseIDs and compares them to a table on a remote SQL server. However, the table holding the CaseIDs on the remote server has nearly 120,000 records.
Currently my plan is to query all records on the remote server, save the query and the current list to tables in an Access DB file and then run an outer join to see which CaseIDs have no matching records on the remote server.
I believe this will be a much slower process than I would like. If I could load both queries into arrays or lists in VB and then compare them (therefore, not having to write 120,000 records to a DB file), it would be much faster.
LINQ Query - Join Tables On Nullable Columns
Apr 17, 2011How to JOIN tables on nullable columns? I have following LINQ-query, RMA.fiCharge can be NULL:
Dim query = From charge In Services.dsERP.ERP_Charge _
Join rma In Services.dsRMA.RMA _
On charge.idCharge Equals rma.fiCharge _
Where rma.IMEI = imei
Select charge.idCharge
I get a "Conversion from type 'DBNull' to type 'Integer' is not valid" in query.ToArray():
Dim filter = _
String.Format(Services.dsERP.ERP_Charge.idChargeColumn.ColumnName & " IN({0})", String.Join(",", query.ToArray))
So I could append a WHERE RMA.fiCharge IS NOT NULL in the query. But how to do that in LINQ or is there another option?
The problem was that the DataSet does not support Nullable-Types but generates an InvalidCastException if you query any NULL-Values on an integer-column. The modified LINQ-query from dahlbyk works with little modification. The DataSet generates a boolean-property for every column with AllowDbNull=True, in this case IsfiChargeNull.
Dim query = From charge In Services.dsERP.ERP_Charge _
Join rma In (From rma In Services.dsRMA.RMA _
Where Not rma.IsfiChargeNull
Select rma)
On charge.idCharge Equals rma.fiCharge _
Where rma.IMEI = imei
Select charge.idCharge
VS 2005 Load Multiple Tables Into A Recordset Using The Join Command?
Jun 3, 2009I've found alot of examples for add/edit/delete a single table. In VB6 ADO you could load multiple tables into a recordset using the join command. Then manipulate or modify the data.
I've found how to retreive multiple tables like,
Da = New OleDb.OleDbDataAdapter("Select groups.groupid,groups.userid,lots.groupid,lots.lotid from groups inner join lots on groups.groupid=lots.groupid order by groups.groupid asc", DB) But the only way I have found to update is to use seperate Update commands for each table.
