  • Ticket #1230 – Description

    initial v4  
    1 WCPS query
     1scaling to an interval that contains any slices should throw an error in rasql.

    4 {{{
    5 for c in (rgb) return encode(c[i(100:100), j(100:100) ], "csv")

    9 WCPS1.5 returns Rasql query

     3Examples:
    114
    125{{{
    136SELECT encode(SCALE(c, [100,243]), "csv" ) FROM rgb AS c
    147}}}
    15 
    16 then returns error

     17In all of these cases rasql should throw an exception: "Invalid scaling minterval".

    33 while Rasql from WCPS 1.0 returns

    36 {{{
    37 select csv(scale( c, [100:100,243:243] )) from rgb AS c where oid(c)=45057
    38 }}}
    39 
    40 and values {"119 208 248"}
    41 
    42 
    43 Then, '''scale in rasql needs trimming interval instead of a slicing point to work''' (?)

     19Scaling in rasdaman is handled in source:qlparser/qtbinaryfunc.cc (QtScale class).
