labview e database mysql

query when, then with labview-mysql

[proteo]

Good evening to everybody, I have to write through labview on a database mysql the following expression:

when this condition is verified:
when (SELECT COUNT(*) FROM tab_accoppiamenti WHERE codice_univoco =222161613) =3

writes this:

(UPDATE riproduttori SET punteggio='4' WHERE codice_univoco =222161613)

how can I do it in an only command mysql?

Thanks in advance for Your answer.
