我想一次将50,000条记录插入sql server database 2000.怎么做到这一点?
您可以使用SELECT TOP子句:在MSSQL 2005中,它被扩展,允许您使用变量来指定记录数(旧版本只允许数字常量)
您可以尝试这样的事情:(未经测试,因为我目前无法访问MSSQL2005)
begin declare @n int, @rows int select @rows = count(*) from sourcetable select @n=0 while @n < @rows begin insert into desttable select top 2000 * from sourcetable where id_sourcetable not in (select top (@n) id_sourcetable from sourcetable order by id_sourcetable) order by id_sourcetable select @n=@n+2000 end end
