User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:41.0) Gecko/20100101 Firefox/41.0
Build Identifier:

Not an important issue, but the following query:

 select case when 1 then 2 else 3 end;

outputs:

 TypeException:user.s28_1[6]:'calc.ifthenelse' undefined in: calc.ifthenelse(X_7:bit,X_8:bit,X_10:bte);
 program contains errors

while it should probably not even create the MAL instruction, and display an SQL error instead.

At some other place, an integer (a byte in this case) is automatically cast to a boolean without error:

 select 1 where 2;
 => [1 ]

For reference, PostgreSQL in both cases throws an error of the form "argument of <...> must be type boolean, not type integer".

Reproducible: Always
