Re: mutating table with trigger

 the mutating error is happened when using row trigger. your trigger also is designed to touch the mutating table. thus won't work properly.

usually, the statement trigger is not concernaed with mutating error.

so, you can solve this problem using below method.

i) before statement trigger. ( creation of table variables ) ii) after row trigger ( inserting values(uquestion) into that tables )
iii) after statement trigger. ( inserting values of table variables into table column )
