连接具有相同列名的 2 个表时出现不明确的列错误

Question

in my table A {ID, FID, Name, Age}
in my table B{ID, Job}

When I use

SELECT ID // I want to get the ID of table B //**error**//
FROM A TA JOIN B TB
ON TA.ID = TB.FID
ORDER BY TA.Name;

Error : ambiguous column name ID

Is there anyway to do that without having to rename the column name? (The Worst scenario)
Thank you

Answer 1

SELECT TB.ID
FROM A TA JOIN B TB
ON TA.ID = TB.FID
ORDER BY TA.Name;

Use the full name (table name and column name seperated by a dot) to specifically select a column.

Your query doesn't fit your described table structure, I guess you swapped table A with table B.

Answer 2

SELECT TB.ID  ...

You need to prefix any ambiguous column anywhere with your table alias.

Answer 3

you don't need to rename anything. you just need to specify the source of ambigous field in SELECT clause since such field exists in both sources (tables)
