问题
I have a need to take in a list of ID numbers corresponding to a member. Their can be anywhere from 10 to 10,000 being processed at any given time. I have no problem collecting the data, parsing the data and loading it in to a DataTable or anything (C#) but I want to do some operations in the database. What is the best way to insert all of this data into a table?
I am pretty sure I don't want run a for each statement and insert 10,000 times.
回答1:
I've used the SqlBulkCopy class before to do a couple million adds. It seemed pretty handy.
回答2:
You may not want to execute an INSERT 10,000 times, but you can wrap those 10,000 inserts into 1 transaction.
回答3:
You can try SSIS for this purpose
回答4:
You can INSERT a SELECT like this:
INSERT INTO myTable (a, b, c) SELECT d, e, f FROM anotherTable WHERE ...
Hope it helps.
回答5:
With SQL Server 2008 you can pass the C# data set (the actual DataTable object) as a table valued parameter. The parameter is available in your Transact-SQL code as an @table variable you can query and manipulate.
