Can someone please explain the differences between REPLACE, INSERT and UPDATE in MySQL?
These are totally different statements.
Insert: Insert new record
Update: Update existing record
Replace: works exactly like INSERT, except that if an old row in the table has the same value as a new row for a PRIMARY KEY or a UNIQUE index, the old row is deleted before the new row is inserted
