在 SQL Server 2008 中,您可以使用 Row Constructor 语法通过单个插入语句插入多行,例如:
In SQL Server 2008, you can use the Row Constructor syntax to insert multiple rows with a single insert statement, e.g.:
insert into MyTable (Col1, Col2) values
('c1v', 0),
('c2v', 1),
('c3v', 2);
除了可读性之外,这样做比为每条记录使用一个插入语句有什么好处吗?
Are there benefits to doing this instead of having one insert statement for each record other than readability?
是的 - 您将看到性能改进.尤其是在记录大量的情况下.
Yes - you will see performance improvements. Especially with large numbers of records.
