which is best using delete or truncate when i need to delete all data from table?-CodePudding

I work on sql server 2017

I need to delete all rows from table student_course

but I don't know which is best for use

delete from student_course

truncate table student_course

Tables Structure

table student_course Structure

studentid pk
courseid  pk

table student table

studentid pk

table courses

courseid pk

student_course table have relation with courses table and student table

so which command will be used to delete all rows from table student_course

truncate or delete ?

CodePudding user response：

I have an foreign key to the table so I will use delete, instead of truncate.

but if i not have forign key then i will use truncate because it faster than delete
