I would like to have a datagridview sourced from multiple db tables.I understand that the datagridview relies on the creation of a datatable and its relations to the separate db tables I want to view.
I have been mucking about with the Designer but dont seem to be getting anywhere, ie. no results from the relations i've built seem to populate the datatable.
I have an ODBC connection to a database, I have 2 tables items, prices. both tables are related via a sequence field. I need a way to load the 2 tables into a datagrid, update fields and then save the changes.items-- itm_seq-- nameprices-- price_seq-- itm_seq-- price_1-- price_2Datagrid needs to show the data as suchname / price_1 / price_2Site updates some cells of the data, hits update.
The records are then written back to the 2 tables accordingly based on the sequence number.. I tried a view that extracts the data and then allows updating, but the datatableadapter will not allow an update statement to be processed against a view.
have a datagridview containing 2 tables left joined, so that:table1 LEFT JOIN table 2 ON table1.id=table2.idI get an error whenever I try to edit my datagridview."invalidOperationException was unhandled by the user codeDynamic SQL generation is not supported against multiple base tables."The error points to this line:
da.FillSchema(dt, SchemaType.Mapped)
da.Update(dt) << This line

I have a vb.net web application and when a particular function runs , i get data timeouts in the rest of the application..(ie..row not found errors or column does not belong to table but it does) The function is adding multiple rows in multiple tables in the database and is running in a for loop. It seems to be all SQL related but I am not seeing anything in the error logs in SQL or in the application Right now I am assuming it is memory related where to start note..the for loop will be replaced with a bulk insert but right now I jest need to resolve the issue of the timeouts

View 12 RepliesI have got a database with a bunch of tables in it. So far, i can query that database and get the names of all the tables into a listbox. this is sweet.
What i need to do now is to enable the user to click on a table name thats listed in the listbox (which were put there using the
GetOleDbSchemaTable method)
and when they do, i need to populate the Datagridview with the relevant data thats sitting in the table that is listed in the listbox.
I've tried a couple things to get the tables themselves to populate the DGV(which kind of works now), but not the Data thats sitting in the individual table.
When I update a record at table [Product] with the integer that stands for [Supplier Name] from joined table [Suppliers], this does not appear in my datagridview. Instead, I have to reload the table to dataset to make it visible. What about datarelation? Is it better that loading a joined table over the dataset? Note that I have never dealed with datarelations before.. How can I make a datagrid column to show "Supplier Name" instead of recordID that represents this supplier?

If I could establish a ODBC connection that would be better, but this will have to work for now with some canned queries I have.

how to create a local database, create some tables and set relations between those tables (just like in access) and I can show, add, edit and delete that data from a form.
but what I have yet to figure out is if I have 2 tables (i.e: tbleName, tblFood) and I want to have multiple tblFood items show for every 1 tblName item.
I've found that if I add a txtbox of the name table and a datagrid of the food table, the datagrid view shows all the food records, not just the ones for the name txtbox.

I have 3 related tables in a DataSet - Customers, Products and Orders.I am trying to create an "editable" DataGridView which, ideally, will contain columns from all the tables. I have tried creating the joins in the TableAdapter SQL, but this results in a read-only data grid.
Customers and Orders are joined in a 1:M relationship by CUSTID.
Products and Orders are joined in a 1:M relationship by PRDID.
When the user adds a new Order record they will key the ORDERID, CUSTID, PRDID and QTY.I would like the DataGridView to display the related CUSNAM and PRDDES as soon as the user has keyed the Order record.The data must be displayed on a single data grid row. I am not interested in drill down or multiple data grids.My data looks like this:
Orders: ORDERID, CUSTID, PRDID, QTY
Products: PRDID, PRDDES
Customers: CUSTID, CUSNAM
The data grid should look like this:
ORDERID, CUSTID, CUSDES, PRDID, PRDDES, QTY
My SQL would look like this:
SELECT Orders.ORDERID, Orders.CUSTID, Customers.CUSNAME, Orders.PRDID, Products.PRDDES, Orders.QTY
FROM (ORDERS
INNER JOIN CUSTOMERS ON Orders.CUSTID = Customers.CUSTID)
INNER JOIN PRODUCTS ON Orders.PRDID = Products.PRDID;
