sql - Select rows which meets criteria and do not -


i have table feature , feature_details feature_details can have lot of features.

  feature_details   feature_deatails_id | feature_id   1                        1   1                        2   1                        4    2                        1   2                        2   2                        4   2                        5

i have blocker in selecting feature_deatails_id's have e.g. 5 feature_id or null absent. output should be:

feature_deatails_id | feature_id 1                     null 2                     5

for example

select feature_deatails_id, min(case feature_id when 5 feature_id end) feature_id my_table group feature_details_id

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
