Is there any alternative to '*' in SQL interfaces?

[Yasufumi Mizoguchi]

Hi,

I'm a newbie and trying SQL interfaces on Solr 6.4.1.

Firstly, I tried to get the values of all fields, but found the following
on 6.4 Draft Ref Guide.

> The * syntax to indicate all fields is not supported in either limited or
unlimited queries.

So, is there any alternative to '*' ?
