scala - Spark SQL- Dynamically select columns which are not nulls in Spark SQL -


i want select columns contains values other null. suppose have table abc:

snapshotdate    creationdate    country region  closedate   probability bookingamount   revenueamount   snapshotdate1   creationdate1   closedate1         null            null       null   null       null   25  882000  0            null            null         null         null            null       null   null       null   25  882000  0            null            null         null         null            null       null   null       null   0   882000  0            null            null         null         null            null       null   null       null   0   882000  0            null            null         null         null            null       null   null       null   0   882000  0            null            null         null         null            null       null   null       null   0   882000  0            null            null         null         null            null       null   null       null   0   882000  0            null            null         null         null            null       null   null       null   0   882000  0            null            null         null         null            null       null   null       null   0   882000  0            null            null         null         null            null       null   null       null   0   882000  0            null            null         null         null            null       null   null       null   0   882000  0            null            null         null         null            null       null   null       null   0   882000  0            null            null         null         null            null       null   null       null   0   882000  0            null            null         null         null            null       null   null       null   0   882000  0            null            null         null         null            null       null   null       null   0   882000  0            null            null         null         null            null       null   null       null   0   882000  0            null            null         null         null            null       null   null       null   0   882000  0            null            null         null         null            null       null   null       null   0   882000  0            null            null         null         null            null       null   null       null   0   882000  0            null            null         null         null            null       null   null       null   0   882000  0            null            null         null

then want select probability, bookingamount , revenueamount columns contains values other null , ignore rest of column contains null values.

i tried doing - select * abc snapshotdate != null , creationdate != null , ..... not each row.

note:- there - sqlcontext.sql("select case when col1 null dont select else select end) x abc")

i using spark 1.6.1

is there way that?

thanks in advance

you need 

select probability, bookingamount,revenueamount abc

if right understand you.

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);
