查询phpmyadmin的问题

Question

我是sql / phpmyadmin的新手，我遇到了这个查询的问题。

SELECT `2.checkNumber`,`1.customerName'
FROM 
`classicmodels1` AS 1,
`classicmodels2` AS 2
WHERE `1.customerNumber`=`2.customerNumber`

Answer 1

替换：

`1.customerName'

与

`1.customerName`

甚至更好地重写它以避免使用引号。我也会分别用't1'和't2'替换别名'1'和'2'：

SELECT t2.checkNumber,t1.customerName
FROM 
classicmodels1 AS t1,
classicmodels2 AS t2
WHERE t1.customerNumber=t2.customerNumber
