DB/Reporting :: Import From Text File To Database (access)
Nov 10, 2009
I am trying to import a text file to an access database in VB2008 express. The text file I am testing with is a csv file with 34,000 records. The problem is this takes 2 minutes to read through all this and write it to the database. The actual text file I will be using in production has over 800,000 records and this will take a ridiculous amount of time. I think I am doing something wrong. I have posted my code below. I am reading a record, parsing out the fields to an array, then creating an SQL statement to insert the record and executing it.
reader = New IO.StreamReader(fname)
Do While reader.Peek() >= 0
linesread = linesread + 1
[Code].....

I have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.
Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?
Here's an example of what I would do:
Hex = 03 00 => dex number 003
Search in file Pokemon Dex Numbers
003 returns Bulbasaur
Check Bulbasaur base stats in the base stats file
etc
So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).
So to cap up the few questions I have:
-Databases are done in SQL and not inside the GUI?
-Databases would load internally?
-I could search a database without having to load it into like an array or something?

I'm using the following code to import data from a text file into an existing Access table:
Code:
Imports System.Data.OleDb
Public Class Carrega_CSV
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code]....
The first time i ran the code, it caused no error but no records where loaded into the table. The second time it causes the OleDbException "Table 'TEMP' already exists." The text file is comma delimited and it has exactly the same number of columns of the TEMP table.

I am just trying figure out a record import program from text file into access database using Microsoft.Jet.Oledb Provider 4.0 and Vb.net. And it seems easy but my problem is different. In the text file, records are not delimited.
Format of the text file:
Field Name & Size
Date[Date,ShortDate]FirstName[20]LastName[20]Sex[1]Age[2]
[Code]....
Can I put delimiter programmatically while reading the text file using stream reader and later simply import the whole file in DB.

Sitll teaching myself how database and all that works. Need someone to make this easy program for me so i can study it better. Here. Here's what im looking for: Load Database from Text File - read a file called stationsin.csv and add the records to the database pupulating the stationID, station name and the state fields,clear Database - delete all records from the database .Load Listbox from Database - clear and populate the listbox from the database.Listbox click event - populate the labels with the data from the database for that specific location.
Create a class called dbUpdt with the following functions: Constructor - accepts the file name of the database and stores it in a class variable. Opens the database and connection. Query - accepts an SQL command and executes it.MoreRecords - returns a boolean variable indicating if there are more records left in the dataset getField - accepts the name of the field and return the contents of the field from the current record close - closes the connection deleteAll - deletes all records in the database addRecord - accepts the table name, the key field name and the key field contents and adds a record to the database with just the key field filled in. setDBField - accepts the table name, the key field name, the key field contents, the field to be updated along with the field's contents and updates a single field within a single record.

I have a machine which creates a new log file at the beginning of the day(12am) and updates the log file whenever there is any changes until the end of the day. How do I import the data in real time (30 sec, 1min or whenever there is any changes) to my SQL server database? Will SQL Server 2008 be able to access the active log file? If not will it be easier if I let my machine create a new log file whenever there is any updates? But if it is so, how do I import so many log files with different names in real time. (I must be able to scale the solution up to multiple machines).

I need to add a button which exports the database to a fixed length text file. Does anyone know the code I would use to do this?

I am trying to import data from an access database to a access database that my project uses I am having problems with combo box fields in the database with the data. I want to import what is displayed instead of the numerical key value. Example: The combo box displays employee names but the value stored is the key value from the employee table so instead of importing John Doe it imports 2 is there a way to make the actual name instead of the number?

I want to move my programs and the database to another computer and hard-disks. It looks to me as though I nearly have to re-create the controls and rewrite some of the code to make it so the programs still work after the move. At least with ODBC all I would change was the DSN definitions external to the programs. Is there an easy way to move or rename a database without loads of work?

I am writing a program for a class and it needs to read/write to an Access 2007 database. Right now I am referring to it's absolute path when I use it in connection strings, something like:
Dim conn As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:UsersMeDocumentsVisual StudioProjectsProject1Database.accdb")
This is going to be a problem when I turn it in obviously, because the professor isn't going to have the same path. So I want to somehow include it into my project and then refer to it with a relative path or something so that it will work on his machine. When I imported it through the Data Sources it had an option at the end to copy the database into the project which I agreed to. It put the Database where all of the source files are on my computer, so I tried using Application.StartupPath(

I have been reading some on .net and databases. I have a fairly large replicated database at work for call logging and I am going to be making a .net app to use for call logging. My question is, do I write a program that connects to the database pulling and pushing data or do I import the database into the .net application and then discard the database? Is it possible to import the database into a .net app? Which is the better idea if they both are possible?
I imagine if I write an app that connects to a database, then I could use a DB that is on our server so that it is like using a replicated DB. Everyones changes being made to the same database. Can multiple users use an app that is connecting to one DB? How can I preserve the replication functionality so that all changes are available to all users?
