I don't know why but the problem is that the clause where don't work in the script.
I have testing an other solution that i find:
Let vLastExecTime = TIMESTAMP(ReloadTime(), 'YYYY-MM-DD hh:mm:ss.fff');
Let Query = 'SELECT * FROM fim.dbo."ORDINE_TAB" WHERE data_creazione > ' & CHR(39) & ' $(vLastExecTime) ' & CHR(39) & '';
And it's work!
Thank you for your help.
