  • Ticket #1049 – Description

    initial v20  
    11Subsetting does not behave very consistently, depending on the actual tiles I'd say (discovered in ticket #1036).
    22
    3 We need to define exactly what the behavior of subsetting should be and make sure it's enforced.
     3Subsetting needs to conform with SQL/MDA, i.e. '''the subset must be within the array sdom'''.

    5 {{{
    6 rasql -q 'select sdom(c) from rgb AS c' --out string --quiet
    7 [0:399,0:343]
     5Anything else, e.g. a subset that intersects or is completely outside of the array sdom is an exception: ''"subset S not within array domain D"''.

    9 rasql -q 'select sdom(c[10:20,*:*]) from rgb AS c' --out string --quiet

    12 rasql -q 'select sdom(c[-10:10,*:*]) from rgb AS c' --out string --quiet

     7Currently we have dedicated systemtest in source:systemtest/testcases_mandatory/test_subsetting the queries should be verified that they produce the correct outputs or errors.
