Re: sql basic question - Mailing list pgsql-sql

Hi Anton,

I need column LABEL  and ID as well. By grouping on SIDE these column cannot be included in the query.

Thanks

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

Then you can do whatever is required...

Thanks,

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
