SQLSTATE[42S22]: Column not found: 1054 Unknown column 'guidian.id' in 'where clause' in yii2

Question

I am new to Yii2 PHP framework, I have student form to get student details and guardian id_no and on submission I get this error SQLSTATE[42S22]: Column not found: 1054 Unknown column 'guidian.id' in 'where clause' The SQL being executed was: SELECT EXISTS(SELECT * FROM guidian WHERE guidian.id='123') The student table has guidian_id as a foreign key referencing id_no on guidian table, I am confused with error to say guidian.id while actually no where I specified an id as a column in guidian table(I don't have id column in guidian table). Note: I understand the typo guidian instead of guardian
