Do the child Select min, max from... Group by side

Then you can do whatever is required...

Hi All,

I have this table:
LABEL     ID                  Distance                 SIDE
"15";     119006;      0.10975569030617;        1
"14";     64054;        0.118448307450912;      0
"16";     64055;        0.176240407317772;      0
"20";     64057;        0.39363711745035;        0
"19";     64056;        0.41205442839764;        1
"24";     119007;      0.59758734628752;        0

What I want to achieve is a result table with min and max distance for each side, limiting to 2 (basically the boundaries of each SIDE)

so the result should be:

LABEL    ID                  Distance                 SIDE

"15";     119006;      0.10975569030617;        1

"19";     64056;        0.41205442839764;        1

"14";     64054;        0.118448307450912;      0

"24";     119007;      0.59758734628752;        0

Thanks a lot

- Antonio
