DB/Reporting :: Changing TableAdapter CommandText At Runtime?
Nov 23, 2009In my app (written in VS 2003) I use OleDbDataAdapter's to load data. I have some functions that enable be to change the OleDbDataAdapter.SelectCommand.CommandText at run time, by adding a "WHERE" or "HAVING" section to the SQL command, or updating the "WHERE " or "HAVING" section. This way I have have generic load data functions. (load all invoices for Customer 123, load all invoices for the year 2009, or load all invoices for Customer 123 for the year 2009).
With the new VS 2008 TableAdapter, the TableAdaper.CommandCollection property is Protected. How can I edit the TableAdaper.CommandCollection(0).CommandText at run time?

IDE :: Changing CommandText Changes Parameters?
Sep 14, 2010I'm trying to edit the CommandText for the Insert Command in a TableAdapter in the Designer in vb.net. Whenever I make changes to the CommandText, Visual Studio (2008) automagically changes the Parameters to a Collection consisting of one Parameter thatexisted before editing the Command, immersed in a sea of complete garbage Parameters, and then I either have to undo (unless this was the first thing I tried editing, in which case I have to close the Designer to discard changes and reopen it) or manuallychange ALL the Parameters back to something that isn't complete garbage.

Jun 8, 2012[Code] The above code does not work. I need for this to check to see if there is a database entry with the office name and today's date. Then if not it needs to tell the user that it is going to create a new entry for todays date. Then the code is trying to enter a new row in the database but it is like i can't use command. commandtext = in two spots. Both SQL commands work if separated but not together in this code. Obviously the abcdefghij are just test entries but it works if it is separated from the other sql command above. Also of course i have changed the datasource above to hide mine.

View 2 RepliesUse SQLClient Class Along With CommandText To Send SQL INSERT?
Feb 9, 2012My general method up until now is I use SQLClient class along with CommandText to send SQL INSERT, UPDATE, DELETE statements dorectly to the SQL Server from the VB app. I have a function I use that will escape any special characters within any string variables. I put a lot of vb database functions in a module that all of my forms can use. When I need to pass data around I send/add arguments to functions using regular variables, etc... I log all of my SQL queries sent to the server to a log file for troubleshooting.So far this has worked well. I know there are better ways to do this, Stored Procedures for example. But I just have not made that leap yet. I'm about to consider turning my world upside down!
I'm MOSTLY interested in creating custom Classes that represent the various objects in my database (Customers, Projects, Invoices, etc...). Then defining all of the properties each of these classes should have: Customer.ID, Customer.Name, Customer.Status, etc... and would like to "map" that Customer object to the database I'm interfacing with. I figure I can wrap all of the SQL commands into methods within each class, i.e.: myCustomer.Name = "Joe Smith"

C# - Same TableAdapter But Different Database

View 2 RepliesTableAdapter Update When There Are No Changes
Aug 3, 2010I'm using TableAdapters in VB.NET (VS2008) to an SQLCE DB. These are associated with a range of DataTables in my DataSet.
I'm trying to simplify my app and I'm wondering : If I call the Update method of a table adapter and there have been no changes, then will the TableAdapter still open the underlying database, or is it smart enough not to bother?
At present I'm using simple boolean flags to keep track of which DataTables have modified data - and it works fine - but I'm just thinking I might be able to simplify my code just by always letting it call the updates. But I only want to do if it won't add an overhead.
Using The Tableadapter.update?
Feb 21, 2011I have a form that has a datagrid thats being filled by data from a temporary database (called Scratchpad3) and what I'm needing to do is to update another table that's not part being called with my table adapter. My table adapter looks as follows:
Me.Scratchpad3TableAdapter.Fill(Me.MDRDataSet.scratchpad3)
and the table that I need to update is called ExceptionsEdit.
.net - TableAdapter Update Fail?
Sep 9, 2010I have a VB windows Form project that connects to several DataTables in an Access DB. On my form I have several textboxes, comboboxes and datetimepickers that are bound to those sources. With one table in particular when I try to update the tableadapter after editing one of the textboxes the update method fails. No exceptions are thrown, but the update method returns a zero value and the data is not updated. The update will work when just the comboboxes or datetimepickers are edited, but as soon as a textbox is edited also, update will not work.
Other DataTables within the project are set up in the same manner but are not having update issues. I can't figure out what about this one particular table is causing an issue. Can anyone give me any thoughts on where or what to troubleshoot?

Can't Get The Identity Value Back From The Tableadapter?
Sep 23, 2009Would I be right in saying that when using tableadapters that you can't get the identity value back from the tableadapter when you insert a row intot a datatable then save the table back to database using tableadapter.update(datatable).It will only return the value of 1?
I would like to return the identity from the table but didn't want to have to assign all the parameters manually in code cause theres about 30
DataTable Isn't Recognized By TableAdapter
Oct 23, 2009I would like to start a data base. Im using vb2005. I've started a new windows application. I have added a new data source to the project. Then I added a new TableAdapter in the dataSet.xsd part of the project. When I'm completeting the wizard, when I click on the QueryBuilder, when the add table window opens, the table already in the program ( that comes along with the TableAdapter ) isn't recognized. I've clicked on the refresh button but it still isn't recognized. (example: DataTable1 isn't recognized in the add table form in the query biulder of DataTable1TableAdapter)

View 6 RepliesSaving Data To TableAdapter?
Nov 17, 2009I have code that saves changes to data on a form and it works fine. I then used the same code on a different form (only changing the name of the bindingsource and tableadapter), but changes I make to the data don't save. Why will it work on one form, yet not on another? Here is the code I am using to save the data on the form that works:
Dim deletedRecords As DataDataSet.CatalogDataTable = CType(DataDataSet.Catalog.GetChanges(Data.DataRowState.Deleted), DataDataSet.CatalogDataTable)
Dim newRecords As DataDataSet.CatalogDataTable = CType(DataDataSet.Catalog.GetChanges(Data.DataRowState.Added),
[code]....
The only difference I see is that on the second form (the one that won't save) I have other tableadapters loaded. But they are just used to load data into different comboboxes. What could be causing the second form not to update the tableadapter? I'm not talking about running the application, making a change, then closing the application and it not saving. I realize that a second database is created because I've set the Copy to Output Directory property to Copy if Newer. I can tell it doesn't save because I run the application, open the form, make a change, close the form, then open the form again. The change I just made is gone.
TableAdapter Does Not Insert New Records?
Oct 6, 2009I have a program that is using a dataset class, table adapter, binding source and binding navigator. The program can read, update, and delete rows from the table. However, it doesn't recognize new records and save them to the database when the table adapter's update method is called. (table was pre-populated by another process) The database table is using an identity column for the primary key. On a whim I added code to force an insert of data using the table adapter's Insert method with some hard coded values and this worked.This code was invoked after hitting new record on the binding navigator bar. Looking at the database, I notice the record I forced in skipped an identity value, which indicates to me hitting new record took the previous number. So the question I have is what would keep the tableadapter from inserting the new record when its update method is called?

Updating An INNER Joined TableAdapter?
Oct 2, 2009I need to get information from two tables onto my form. I'm using a DataGrid called SQLGrid which I'm populating in code with the information I need to get out of both tables.
Private connstr As String = "Data Source=MAUDOT3;" & _
"Initial Catalog=ExxColl;" & _
"Integrated Security=True;"
[code].....
I need my application to be able to update the DataGrid, and commit those updates to the database. My problem is that all the research I've done so far has led me to believe that there's no way I can do this because the SqlDataAdapter.Update() method only updates 1 single table.I just had an idea to make my event handler execute a stored procedure that creates a view on the database, populates it with data from my dataset, and then distributes the information between the two tables where needed.I guess another solution would be to use 2 DataGrids and then tie each of them into a seperate DataAdapter/DataSet, and then update each when the Event is called. The problem here would be that it's more work for the end user to make changes, so I'd really prefer to do it another way.
