ambiguous column error when joining 2 tables which have the same column name
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 开发者_开发技巧scenario)
Thank youSELECT 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.
SELECT TB.ID ...
You need to prefix any ambiguous column anywhere with your table alias.
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)
