The PHP error "QueryException: SQLSTATE[42S22]: Column not found" typically occurs when your application tries to access a column in your database that does not exist. This could be due to a typo in the column name or because the column has been renamed or deleted. It could also occur if the database schema has not been correctly set up or updated.

Example:

// table

 

CREATE TABLE Users (

    ID int,

    LastName varchar(255),

    FirstName varchar(255)

);

 

// wrong query

 

insert into Users (ID, LastName, FirstName, PhoneNumber) values (1, "Kowalsky", "John", "123456789");
