Question

Is it possible to declare java attribute name using specials characters, exemple:

private String var/name;
private int one+one;

I ask this question because I need to retrieve data from DB, whose the name of one colomn is annoces/status, And I need to use sql query (not hql or criteria)

Answer 1

It’s not possible to do that:

Variable names are case-sensitive. A variable’s name can be any legal
identifier — an unlimited-length sequence of Unicode letters and
digits, beginning with a letter, the dollar sign “$”, or the
underscore character “_”. The convention, however, is to always begin
your variable names with a letter, not “$” or “_”. Additionally, the
dollar sign character, by convention, is never used at all. You may
find some situations where auto-generated names will contain the
dollar sign, but your variable names should always avoid using it. A
similar convention exists for the underscore character; while it’s
technically legal to begin your variable’s name with “_”, this
practice is discouraged. White space is not permitted.

I don’t understand why you need that though.

Edit

You can use something like bbr.sendQuery(“Select Status, Name, Annonces/Sta AS annoncesSta, From table “,MyObject.class); with AS you can change the name of the column that you receive in the result. So your attribute in the java class can be “annoncesSta”.

Anyway is wired to have column names with “/”, best practices for names are:

• AnnoncesSta
• announces_sta

And most mappers handle those names automatically.
