Fast batch insert/update with SQL Server 2008 and BCP
I'm not a good SQL programmer, I've got only the basics, but I've heard of some BCP thing for fast data loading. I've searched the internet and it seems to be a command-line only utility, and not something you can use in code.
The thing is, I want to be able to make very fast inserts and updates in a SQL Server 2008 database. I would like to have a function in the database that would accept:
- The name of the table I want to execute an insert/update operation against
- The names of the columns I'll be feeding data to
- The data in a CSV format or something that SQL can read stupid-fast
- A flag indicating weather the function should perform an insert or update operation
This function would then read this CSV string and genarate the necessary code for inserting/updating the table.
I would then write code in C# to call that function passing it the table name, column names, a list of objects serialized as a CSV string and the insert/update flag.
As you can see, this is intended to be both fast and generic, suitable for any project dealing with large amounts of data, and thus a candidate to my company's framework.
Am I thinking right? Is this a good idea? Can I use that BCP thing, and is it suitable to every case?
As you can see, I need some directions on this... thanks in advance for any help!
In C#, look at
Have you considered using SQL Server Integrated Services (SSIS). It's designed to do exactly what you describe. It is very fast. You can insert data on a transactional basis. And you can set it up to run on a schedule. And much more.
