What is the best way to remove duplicate rows from a fairly large SQL Server
table (ie 300,000+ rows)? 从至关大的SQL Server
表(即300,000+行)中删除重复行的最佳方法是什么? ide
The rows, of course, will not be perfect duplicates because of the existence of the RowID
identity field. 固然,因为存在RowID
标识字段,所以这些行将不是完美的重复项。 spa
MyTable MyTable .net
RowID int not null identity(1,1) primary key, Col1 varchar(20) not null, Col2 varchar(2048) not null, Col3 tinyint not null
