Code Inspection: Check using clause columns
Reports columns in the USING clause that does not exist in both tables.
In USING clauses, a column name must be present in both tables, and the SELECT query will automatically join those tables by using the given column name. As we do not have the
j column in
t2, we can rewrite the query using ON. The ON clause can join tables where the column names do not match in both tables.
