Cast to bool in RasQL

[Piero Campalani]

Casting to a boolean (scalar or marray) does not seem to work in RasQL: it seems to take the first byte instead of evaluating whether the number/cell is not 0:

$ rasql --user rasadmin --passwd rasadmin --out hex -q "select ((bool)((c) [3,50:52,151])) from eobstest AS c":
  Result object 1: 48 7b b1 

$ rasql --user rasadmin --passwd rasadmin --out hex -q "select (((c) [3,50:52,151])) from eobstest AS c"
  Result object 1: 48 fd 7b fc b1 fb 

With scalars, things work, although there is still a problem with the CSV encoding (#588).

$ rasql --user rasadmin --passwd rasadmin --out string -q "select ((bool)(100)) from eobstest AS c"
  Result element 1: t    <- OK

$ rasql --user rasadmin --passwd rasadmin --out string -q "select csv((bool)(100)) from eobstest AS c"
  Result object 1: {100} <- WRONG

Lowering priority since WCPS queries can still allow non-CSV encoded scalar expressions.

Do we want CSV converter return 0/1 for boolean values, or T/F, or t/f?

Let's set it to t/f, seems like this is what rasql outputs.

Can be closed, right?

[Veranika Liaukevich]

Yes, it was fixed in changeset:c6523460dc and changeset:0310ad111.
Btw, I don't receive emails when patches are applied anymore. Was it done intentionally?

[Dimitar Misev]

Me neither, I have to check what happened with that.
