判断出现次数是否相同
有如下表:
table1
batchidId Id passtimes
101 A01 1
102 A01 2
103 A02 1
104 A02 2
105 A03 1
106 A04 1

table2
batchidId Id state
101 A01 pass
102 A01 pass
103 A02 pass
106 A04 pass

table3
id  
A01  
A02  
A03  
A04  

我现在要在table3中取所有id曾经在 table1,table2中出现过的,并且在table1中出现的次数与table2中次数一样的数据


希望得到的数据位
id
A01
A04

写在一条sql中,关键是where后面的不怎么会写,求高手

------解决方案--------------------
SQL code
SELECT * FROM TABLE3
WHERE (SELECT COUNT(*) FROM TABLE1 WHERE ID = A.ID) =
(SELECT COUNT(*) FROM TABLE2 WHERE ID = A.ID)

SQL code

--> 测试数据:[table1]
if object_id('[table1]') is not null drop table [table1]
create table [table1]([batchidId] int,[Id] varchar(3),[passtimes] int)

select id from table3 where id in(

/*
