展开全部

select * from A

inner join B on A.Name = B.Name and A.ID = B.ID

where A.Name = '张三' and A.ID = '008'

内连接即可

或者：

1、除重

select distinct A.ID AS AID,A.Name AS AName,B.ID AS BID,B.Name AS BName from A inner join B on(A.Name=B.Name and A.ID=B.ID)

2、除重

select A.ID AS AID,A.Name AS AName,B.ID AS BID,B.Name AS BName from A inner join B on(A.Name=B.Name and A.ID=B.ID)

SQL的其他查询

1、查找表中多余的重复记录，重复记录是根据单个字段（peopleId）来判断

select * from peoplewhere peopleId in (select peopleId from people group by peopleId 

having count(peopleId) > 1)

2、删除表中多余的重复记录，重复记录是根据单个字段（peopleId）来判断，只留有rowid最小的记录

delete from peoplewhere peopleId in (select peopleId from people group by peopleId   

having count(peopleId) > 1)and rowid not in (select min(rowid) from people group by 

peopleId having count(peopleId )>1)

3、查找表中多余的重复记录（多个字段）

select * from vitae awhere (a.peopleId,a.seq) in (select peopleId,seq from vitae group by 

peopleId,seq having count(*) > 1)

4、删除表中多余的重复记录（多个字段），只留有rowid最小的记录

delete from vitae awhere (a.peopleId,a.seq) in (select peopleId,seq from vitae group by 

peopleId,seq having count(*) > 1)and rowid not in (select min(rowid) from vitae group by 

peopleId,seq having count(*)>1)

5、查找表中多余的重复记录（多个字段），不包含rowid最小的记录

select * from vitae awhere (a.peopleId,a.seq) in (select peopleId,seq from vitae group by 

peopleId,seq having count(*) > 1)and rowid not in (select min(rowid) from vitae group by 

peopleId,seq having count(*)>1)
