Drop Foreign Key without knowing the name of the constraint?

Question

I have created one table using below command:

create table Table1(
    Id int Not Null 
        Foreign key 
        references Table2(Id)  
        on delet         


        

Answer 1

You can find the name of the constraint in INFORMATION_SCHEMA.TABLE_CONSTRAINTS

select CONSTRAINT_NAME
from INFORMATION_SCHEMA.TABLE_CONSTRAINTS
where TABLE_NAME = 'Table1'
