1. 表结构相同的表,且在同一数据库(如,table1,table2)
insert into table1 select * from table2 # 完全复制 insert into table1 select distinct * from table2 # 不复制重复纪录 insert into table1 select top 5 * from table2 # 前五条纪录
insert into table1(a,b,c) select a,b,c from table2 # 插入指定字段值
2. 不在同一数据库中(如,db1 table1,db2 table2)
insert into db1.table1 select * from db2.table2 #完全复制 insert into db1.table1 select distinct * from db2.table2 # 不复制重复纪录 insert into db1.table1 select top 5 * from db2.table2 # 前五条纪录
insert into db1.table1(a,b,c) select a,b,c from db2.table2 # 插入指定字段值
