Rasql_Error when scale axis to a slicing point

[Bang Pham Huu]

scaling to an interval that contains any slices should throw an error in rasql.

Examples:

SELECT encode(SCALE(c, [100,243]), "csv" ) FROM rgb AS c

and

SELECT encode(SCALE(c, [100:102,243]), "csv" ) FROM rgb AS c

and

SELECT encode(SCALE(c, [100,100:243]), "csv" ) FROM rgb AS c

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

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

[Dimitar Misev]

Please check if scaling to a point is valid in the WCPS standard, perhaps an interval is mandatory.

Dimitar, I think in this case, Rasql should throw an exception when scale at a point, instead of error like this.

rasql -q "select csv(scale( c, [100,243] )) from rgb AS c " --out string
