如何显示多个与其他表中的列名称相同的查询表中的列？

Question

I have the following query:

SELECT a.column, b.column FROM a, b WHERE a.userid = b.id

Would like to be able to differentiate which column to display since the columns in both tables have the same name.

Clearly, if I use $row['column'] it only returns one of the values. I have tried $row['b.column'] to differentiate the table, but that did not return anything.

Answer 1

使用别名：

SELECT a.column AS aColumn, b.column AS bColumn FROM a, b WHERE a.userid = b.id

Answer 2

You can name the column as you want using alias "AS", eg:

SELECT a.column AS other_name, b.column AS b_column FROM a, b WHERE a.userid = b.id

Then you can call $row['other_name'] or $row['b_column']
