Insert Many Records Into Oracle Table?
Jun 9, 2011Relatively 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.

Move Records From An Oracle Database Into SQL Server?
May 22, 2010A VB.net program reads the queue and calls a stored proc in SQL Server that processes and then inserts the message into another SQL Server table and then deletes the record from the oracle table.
We use a DataReader to read the records from Oracle and then call the stored proc for each of the records. The program seems to be a little slow. The stored procedure itself isn't slow. The SP by itself when called in a loop can process about 2000 records in 20 seconds. But when called from the .Net program, the execution time is about 5 records per second.I have seen that most of the time consumed is in calling the stored procedure and waiting for it to return.[code]...
Print Records From Oracle To Epson Printer
Nov 27, 2008I have a user entering records into an Oracle db. Now I want the user to be able to specify a type of tag which is stored in the db, specify a printer, the number of copies they want and it prints it for them.
I'm automatically setting the default printer to a lexmark printer using an Epson driver(Since this us what I'm testing on). I've been able to print one tag so far. If the user specifies that they want 50 tags of a type then the system should print 4 tags parrallel to each other until it reaches 50. Then it moves on to the next batch of tags specified.

Add Student Average Information To Properties Of Student Records Created In Previous Sub Procedure?
Apr 19, 2010I have created a class called Student, with five private variables: [code] My main form is divided into a number of different sub procedures. In one of them, I used a streamreader to take the first name, last name, and phone numbers of a list of records in a text file called PersonalInfo.txt. It seems to work just fine. [code] I have another, separate sub procedure in which I read a different text file containing the "averages" for the students. The first average from Averages.txt belongs with the first student in PersonalInfo.txt. The second average goes with the second student.. How do I add the student average information to the properties of the student records created in the previous sub procedure? [code] I realize why this wouldn't work, but I can't figure out how I could use my counter to reference a specific student.
