Questions tagged [reserved-words]

reserved words are specific words in any language which are banned from use by authors, because of the special meaning they have in the language.

The language may have reserved words it is not currently using (Java has goto). While generally unwanted, new reserved words may also be added as the language evolves (since the version 1.5 Java treats enum as a reserved word, causing problems for the old code).

Some words that are commonly assumed as reserved are actually not reserved (for instance, it is ok to write int String = 1 in Java).

Cannot create a database table named 'user' in PostgreSQL

It seems PostgreSQL does not allow to create a database table named 'user'. But MySQL will allow to create such a table. Is that because it is a key word? But Hibernate cannot identify any issue (even if we set the PostgreSQLDialect).

Is it bad practice to use a built-in function name as an attribute or method identifier?

I know to never use built-in function names as variable identifiers. But are there any reasons not to use them as attribute or method identifiers? For example, is it safe to write my_object.id = 5, or define an instance method dict in my own class?
