SQL Error [1052] [23000]: Column 'username' in field list is ambiguous Column 'username' in field list is ambiguous Column 'username' in field list is ambiguous how to fix this anwers in english
The SQL error you're seeing, "Column 'username' in field list is ambiguous," means that this column exists in more than one table in your query, and SQL isn't sure which one you're trying to access.
To fix it, just prefix "username" with the name of the table or the alias you are referencing it from. For example, if 'username' resides in the 'users' table and 'subquery' alias, instead of just using 'username' in your SELECT clause, you can use 'u.username' or 'subquery.username'. You need to make this change for every occurrence of 'username' in your SELECT and GROUP BY clauses.
