approximation" (was: No syntax available in SQL representation of Query for
"functiona approximation")
> No syntax available in SQL representation of Query for "function

> Key: METAMODEL-200
> URL: https://issues.apache.org/jira/browse/METAMODEL-200
> Project: Apache MetaModel
> Issue Type: Bug
> Reporter: Kasper Sørensen
>
> In MetaModel we have a flag that can be set on e.g. "COUNT( * )" which
> indicates if the database may approximate the number instead of doing a
> consistent calculation. This is good for optimization scenarios where you
> don't need an actual count, just an estimate (for progress bars and similar
> stuff in UIs).
> But unfortunately we don't have any syntax support for this when dealing with
> String queries. Shouldn't we add that?
> I could imagine a prefix or something like that, e.g. the "tilde / ~" symbol,
> like this:
> {code}
> SELECT ~COUNT(*) FROM table
> {code}
