Hi all, I have this generic routine that I wrote that takes a list of sql strings and executes them against the database. Is there any way I can make this work faster? Typically it'll see maybe 200 inserts or deletes or updates at a time. Sometimes there is a mixture of updates, inserts and deletes. Would it be a good idea to separate the queries by type (i.e. group inserts together, then updates and then deletes)?
I am running this against an ms access database and using vb.net 2005.
Public Function ExecuteNonQuery(ByVal sql As List(Of String), ByVal dbConnection as String) As Integer
If sql Is Nothing OrElse sql.Count = 0 Then Return 0
Dim recordCount As Integer = 0
Using connection As New OleDb.OleDbConnection(dbConnection)
connection.Open()
Dim transaction As OleDb.OleDbTransaction = connection.BeginTransaction()
'Using cmd As New OleDb.OleDbCommand()
Using cmd As OleDb.OleDbCommand = connection.CreateCommand
cmd.Connection = connection
cmd.Transaction = transaction
For Each s As String In sql
If Not String.IsNullOrEmpty(s) Then
cmd.CommandText = s
recordCount += cmd.ExecuteNonQuery()
End If
Next
transaction.Commit()
End Using
End Using
Return recordCount
End Function
