I have two tables in my database:
NEWS table with columns:
id - the news id user - the user id of the author)USERS table with columns:
id - the user idI want to execute this SQL:
SELECT * FROM news JOIN users ON news.user = user.id When I get the results in PHP I would like to get associative array and get column names by $row['column-name']. How do I get the news ID and the user ID, having the same column name?

Explanation: This error occurs when the referenced column can't be resolved unambiguously. This may occur when you have two tables that have columns with the same name.
An invalid column name error in SQL means that the column name violates the conditions of the column name. If you reference an object that does not exist in the table or the name exists, but you did not reference it correctly, you will get this error.
Ambiguous error means that you are calling a certain field in which exist in both Table and the SQL has no idea where to get it.
Ambiguity errors occur when erasure causes two seemingly distinct generic declarations to resolve to the same erased type, causing a conflict.
You can set aliases for the columns that you are selecting:
$query = 'SELECT news.id AS newsId, user.id AS userId, [OTHER FIELDS HERE] FROM news JOIN users ON news.user = user.id' If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
