View 1 RepliesRelatively new to VB.NET coding. Am creating a pretty simple console application that needs to insert over 50,000 records into an Oracle table (OleDB connection). I tried 3 different methods so far: Individual INSERT, insert using a dataset, & using INSERT ALL (commit every 25 records due to # of columns). It seemed like most articles/posts I read recommended the dataset approach, but the INSERT ALL code was definitely the fastest by far.

In my code I have an Oracle command that contains an INSERT statement. Here's a snippet from my SQL:
"'," & "To_Date('" & Format$(dtDateTime_Stamp, "MM/dd/yyyy hh:mm") & _
The value of strDateTime_Stamp is #1/19/2011 9:42:22 AM# I'm getting an error ( "ORA-01830: date format picture ends before converting entire input string") because I don't know how to correctly assign the AM/PM tag on the end -- you'll notice it just says "MM/dd/yyyy hh:mm" in my code. I've tried a bunch of different things but nothing works. I also find it odd that if I change the "MM/dd/yyyy hh:mm" to "mm/dd/yyyy hh:mm" (little m for month) it gives me a 42 for the month value, not a 1. The capital M's fix that but I'm curious to know why.how to I get it to show the AMPM on the end?

View 1 RepliesI have the following insert into statement. What I want to do is insert the values to gprdsql.TblOracleNos if TxtOracleNo is not empty, therefore if a user logs on and fill the textbox the values are saved to the table. However, if the oracle number exists in gprdsql.TblOracleNos (i.e, the values ) it should not insert the values, presently it creates the same record again with same values (when the save button is clicked) and this creates duplication. Instead probably bring a pop up message "Oracle number already exists. [Code]

Trying to insert 315K Gif files into an Oracle 10g database. Everytime I get this error "ora-01460: unimplemented or unreasonable conversion requested" whe I run the stored procedure. It appears that there is a 32K limit if I use a stored procedure. I read online that this does not apply if you are doing a direct insert, but I do not know how to create the insert string for a Byte Array. This is a thick client running on the server so not worried about SQL Injection attacks.

View 3 RepliesNew to programming completely,on VB 10 Express. I am in the process of creating a keypad which I can punch in numbers 1- 9 to enter a password. I have 9 buttons for the numbers. I've got the keys to print the numbers into the textbox above but when I press a second key it replaces the first number in the text box.
My question is, how do I make the numbers go in sequence, so instead of
(Press 1) - 1 -
(Press 2) - 2 - (clears 1)
I want it to go like
(Press 1) - 1 -
(Press 2) - 12 -

And I also have this method, where I take two files and take some values from them, and then I merge all the values into an object in the second query:
Public Shared Function RetrieveTranslation(ByVal filefrom As String, ByVal fileto As String) As List(Of clsTranslation)
Dim valuefrom = (From l In XElement.Load(fileto).Elements("data") Select l.Element("value").Value).FirstOrDefault
[Code] .....
So, the problem is that when I run the code, there is an "Sequence contains no elements" error in the first query(valuefrom). I debugged and it says that there is nothing in the query, but I don't understand why? I'm curious to know if it is well done to do something like I did, create an object from two queries, putting the first value in the second query.
While going thru an msdn article, I found a reference to System.Query.Sequence class. But when I try to use it, I get error "Query is not a member of System"

Select New With {.Number = n, .OddEven = If(n Mod 2 = 1, "odd", "even")}
For Each n In numbers

The above code is vb.net version of this code from msdn. So what is the correct namespace of this class? Or I'm missing something else?
