# title:        Using where params in SUM return incorrect results
# decription:   
#                   30.10.2019. NB: new datatype in FB 4.0 was introduces: numeric(38,0).
#                   It can lead to additional ident of values when we show them in form "SET LIST ON",
#                   so we have to ignore all internal spaces - see added 'substitution' section below.
#                   Checked on:
#                       4.0.0.1635 SS: 1.061s.
#                       3.0.5.33182 SS: 0.754s.
#                       2.5.9.27146 SC: 0.190s.
