The code you posted would not work in VFP: you'd get duplicates in a typical multi-user scenario every now and then, which is what you want to avoid, right?
So that in any case, any backend including Vfp DBC/DBF, you might want to create a "unique" constraint, something like a "Primary Key" or "Candidate Index" in VFP.

However, a few backends are supporting the relatively new SQL "Merge" standard command, like DB2, MS SQL Server, Oracle.
So it depends on what backend you are using - since you mentioned MySQL, they are having a similar feature that looks like "INSERT ... ON DUPLICATE KEY UPDATE ..." as far as I know.
I believe a web search would bring up links like
