While executing an INSERT statement with many rows, I want to skip duplicate entries that would otherwise cause failure. After some research, my options appear to be the use of either:
ON DUPLICATE KEY UPDATEwhich implies an unnecessary update at some cost, orINSERT IGNOREimplies an invitation for other kinds of failure to slip in unannounced.
Am I right in these assumptions? What's the best way to simply skip the rows that might cause duplicates and just continue on to the other rows?
