我有3张桌子,所有桌子都与PK和FK联系在一起。表格为acc_details,acc_info,acc_bill
TABLE : acc_info
ID | acc_no | rate
______________________________________
1 | 00001 | 0
2 | 00002 | 21
3 | 00003 | 21
4 | 00004 | 21
TABLE : acc_details
id_dls | acc_type | address | **ID**
________________________________________________________
1 | store | pekan | 1
2 | water plant | kuantan | 2
3 | store | kuantan | 2
4 | pump house | kuantan | 4
TABLE : acc_bill
id_bill | acc_no | charge_1 | charge_2
________________________________________________________
1 | 00001 | 20.00 | 12.00
2 | 00002 | 15.00 | 16.00
3 | 00004 | 200.00 | 22.00
PK ---> ID,acc_no FROM acc_info FK ---> ID FROM acc_details,acc_no FROM acc_bill
我希望结果是这样的
address | acc_no | rate | charge_1 | charge_2
_________________________________________________________________________________
pekan | 00001 | 0 | 20.00 | 12.00
kuantan | 00002 | 21 | 15.00 | 16.00
kuantan | 00004 | 21 | 200.00 | 22.00
现在,我试过这个
SELECT address , acc_no , rate , charge_1 , charge_2
FROM acc_info , acc_details , acc_bill
WHERE acc_info.id = acc_details AND acc_info.acc_no = acc_bill.acc_no
但错误#1052 - 字段列表中的列'acc_no'不明确 有人可以帮忙吗?
答案 0 :(得分:1)
SELECT address ,
acc_info.acc_no ,
rate ,
charge_1 ,
charge_2
FROM acc_info
JOIN acc_details ON acc_info.id = acc_details.id
JOIN acc_bill ON acc_info.acc_no = acc_bill.acc_no
这意味着acc_no
存在于两个连接的表中,因此您需要指定您想要的acc_no
