Shaun Forbes commented on EMPIREDB-209:
---------------------------------------

Hey,
No, I'm not 100% sure, as you say the docs are a little thin.
I think it was Postgres that I ran into the issue with however.
I'll have another look tomorrow.
Cheers

> I believe it's possible in sql to use a reserved word as an alias in a select statement
if it's correctly quoted (it is for the databases I've tested anyway).
> Checking for and quoting reserved word aliases does not currently appear to be implemented.
> To overcome this limitation I've added an method to the DBDatabaseDriver class to add
the alias and perform any required quoting and altered the DBAliasExpr class to delegate the
adding of the alias to the DBDatabaseDriver class.
> The character I'm using for quoting is determined from the getIdentifierQuoteString()
method of the database connection metadata class, and I've used the detectQuoteName(String
name) method in DBDatabaseDriver to determine if the alias needs to be quoted.
> Patches available if required.
