Using LIMIT 1 in MySQL

Question

When is it appropriate to add LIMIT 1 at the end of the query in MySQL. I normally add it in DELETE but I\'ve seen it being used with INSERT a and even UPDATE. Is it an overkill

Answer 1

I can't think of an instance where something that speeds up a query and makes it more secure at the same time could be called overkill. I'll put my vote in the good practice column.
