Upload data to a mysql database
Briefly

The application is generating a fatal error due to an SQL query trying to access a non-existent column called 'manufacturer'. This error, stemming from a PDOException, highlights a critical issue in either the SQL statement or the database schema. Checking the database structure or revising the SQL statement to match the existing columns will be necessary to resolve this problem and prevent future execution failures.
The error indicates that the SQL query is attempting to access a column named 'manufacturer' that does not exist in the specified database table.
This exception is raised when the PDO is unable to find the column in the database schema, signaling a potential issue with the SQL statement or database structure.
