if/else statement ignored by Python 3

I have faced error problem as my if statement don't work. I have an existing database by sqlite3, using python 3, i have a column in my db named "borrow".
My "borrow" by default has data '0' stored.
Thus, i did an if else statement like:

c.execute("SELECT borrow FROM adminData where name = user_input")       
conn.commit()    
borrowR = c.fetchall()    
if borrowR == "0":    
    print("New")    
else:    
    print("Exists")    

When i run my program, nothing shows. Nothing is printed out. What is wrong here? In my if else statement.
