如何连接2表并使用两个表中的公共列选择特定列

Question

我有两个不同的表，例如table1和table2，因为我有一个共同列customer_id，然后我想从customer_loan中选择table1和来自customer_name的{​​{1}}使用公共列table2并加入并显示在我的页面中，任何人都可以帮助我

Answer 1

很简单

SELECT table1.customer_loan,table2.customer_nam
FROM   table1 INNER JOIN table2 ON (table1.customer_id =table2.customer_id)

Answer 2

试试这个

select table1.customer_loan,table2.customer_nam from table1 inner join table2 on table1.customer_id = table2.customer_id

Answer 3

您需要JOIN，如下所示：

SELECT table1.customer_loan, table2.customer_nam
FROM table1 JOIN table2 
USING (customer_id)
