1. 表結構相同的表，且在同一資料庫（如，table1,table2)

insert into table1 select * from table2  # 完全複製

insert into table1 select distinct * from table2 # 不復制重複紀錄

insert into table1 select top 5 * from table2  #前五條紀錄

2. 不在同一資料庫中（如，db1 table1,db2 table2)

sql: insert into db1.table1 select * from db2..table2  #完全複製

 
insert into db1.table1 select distinct * from db2table2 # 不復制重複紀錄

insert into tdb1.able1 select top 5 * from db2table2  # 前五條紀錄
