Hello everyone
There is the possibility of ordering the result of a SELECT in an order
specified by the user.For examplehaving a field NAMEin the clause ORDER BY
'PAUL, JOHN, PETER, MARIA'
Of course, that should be all the options set

I don't think so.
And anyway, you should never be using an order by number - unless there is
really no way around it, in my opinion.

I am of this opinion because SQL scripts change and what is today column
number 2 may become column number 14 two days later.
This, in turn, leads to potential problems because you think it's ordering
by something whereas instead it's ordering by something else.

Thanks. Knowing this reasoning, one can then use one's judgement in
comparing this reason against a desire to avoid repeating a long complex
expression which could also lead to a maintenance risk.

in an outer select giving it an intuitive column name.
It does not work in *all* cases, but it does work in most.

This should work fine if you place a comma after A.Codigo. It does
not make any sense to ORDER BY 2 (nor ORDER BY 1,2)
hi helen... the comma is the less problem...

'00' as MEIO_PAGAMENTO,

I tried the sorting inside and outside a minimal view and it actually

Hi SET,

Your SQL worked with a small amount of change in below statement

Because FK_BOM2 is of GUID type.
