[Prometheus-library] SqlUtil bug

[Oskar <os...@2n...>]

Hi,

First of all - excellent idea and great work!

I found a small bug within library:
   SqlUtil object - function SelectStatement - when I pass multiple tables 
as a parameter it doesn't
   generate proper query - tables are not divided by comma
   Fix:
        $more_than_one++    in loop for tables (the same is done for columns)
