Re: Identity question

Something like:  SELECT max(number) +1 from table where branch =
:myBranch and point = :myPoint   ?

Will that work well when two or more processes use it?

,,Raul,

Wouldn't it better to create a function that receives the branch and point
of sales ID and returns the number or string desired?

The Paraguayan version of the IRS (SET) requires that we assign
consecutive numbers to the documents (Bills) starting with one for each
branch and point of sale.

Can I get the system to generate the numbers? I had only seen one
sequence per file.

The numbers must have this format 001-001-0000001 First tree digits
are the branch, second group is the point of sale and the last seven
digits must be generated.

If not automatic, will a trigger be the best option?

código asignado por el contribuyente a cada punto de expedición dentro
de un mismo establecimiento; y

c) Separada por un guion, la numeración secuencial de siete dígitos.
