Re: synonyms for table columns - are they possible?

Hello,
  Synonyms can also by used for: Data base links, packages and views but not schemas.

 A view is a stored query. The 'where' clause can be added to by the user without having to know the underlying data sources. It behaves like a table when used in other queries. If expressions are used to calculate a column result then column aliases must be used to name the expression.

Aliases are used in queries (or update statements) to give a name to a table, columns or column expressions to identify it within the query (or sub-query).

| Actually synonyms, aliases and views are three different things.
| Synonyms are an alternate name for a table created with a create
