I am looking for the correct configuration to allow a variable for the Where modifier of the SqlCeCommand(Update) routine. Within the database, T01 is a bigint field, and T02 and T03 are nvarchar fields. A literal coding such as Where T01=2 works fine, but an attempted variable configuration such as above produces the error The column name is not valid. [ Node name (if any) = ,Column name = T03Ctr ] at the ExecuteNonQuery() line.
I have a gridview that is set to a sql datasource, it is generating the columns automatically. If I add a column to the table it is referencing, it will draw that column and display it, but it does not update the insert/update commands to include the new column. Is there any way have it rebuild those commands automatically?
View 1 RepliesI have a gridview in which when I click edit, update, and cancel button comes. I have a variable named status. If status=false then update should change to insert and if status=true then update should be update itself.

I am trying to figure what is the best way of using SQL in my app in the manner of run time.I need to select data from my database let say 60 times a day maybe more I can use the dataset and its adapters or use the SqlCeCommand to build my own Q What do you recommend?
View 2 RepliesUPDATE: I've modified the code to drop the indexes before the inserting, but it makes not difference.I've been asked to resolve an issue with a .Net/SqlServerCe application. Specifically, after repeated inserts against the db, performance becomes increasingly degraded. In one instance at ~200 rows, in another at ~1000 rows. In the latter case the code being used looks like this:
Dim cm1 As System.Data.SqlServerCe.SqlCeCommand = cn1.CreateCommand
cm1.CommandText = "INSERT INTO Table1 Values(?,?,?,?,?,?,?,?,?,?,?,?,?)"
For j = 0 To ds.Tables(0).Rows.Count - 1 'this is 3110
[code]....
The specifics aren't super important (like what 'tbl' is, etc) but rather whether or not this code should be expected to handle this number of inserts, or if the crawl I'm witnessing is to be expected.
with the following code example:
T04Command04 = New SqlCeCommand("Update GameResults Set CN01=@T04Var02 Where Counter=@T04Var03", T04Database01)
T04Command04.Parameters.AddWithValue("@T04Var02", T04N01)
T04Command03.Parameters.Add("@T04Var03", T04ClnRec01)
T04Command04.ExecuteNonQuery()
I am trying to use two different variables in this SqlCeCommand series, to (1) update only a particular record in the database (2) with a particular variable value. However, I get the following error:
"An SqlCeParameter with ParameterName 't04var03' is not contained by this SqlCeParameterCollection."
I have search online but find no tutorial/sample code in DataGridView which show how to insert, update delete.

I have a problem with this code.It loops all records in tables SAP_CC and ORCL_CC and matches all records where amounts are equal in both tables. The problem arises when I need to update the tables.I need to update a column on tables SAP_CC and ORCL_CC, setting the records as matched and also to create new records on the CC_RECONCILED table.
In the If End If the line .Open("CC_RECONCILED") throws the COM Exception:Operation is not allowed when the object is open. I cannot close rslIs there a way of achieving my goal?
I've got results in a loop format from a XML file, I want to either insert them into my SQL database or update them if they are already there. My question is more around lodgic, do I have to
1. Get each item.
2. Do a search for it and see if it's in there.
3. If not add
4. If so update
Or is there a quicker way because with 200 records at a time, search then update/insert will slow down the process.

View 1 RepliesI have a datatable populated from an SQL Server 2008 database table. I created a DataAdapter with a commandbuilder to manage the updating, inserting, and deleting of records. The Updating and Inserting work as expected. However, Delete does not. The code runs through just fine without any errors. The number of records in the datatable after the row is deleted even reflects the deletion. The DataAdapter.Update works fine without any exceptions. But when checking the actual table in the SQL DB the deleted record is still there.Here are the parts of my code that deal with this table.
