tbl_sql: Create an SQL tbl (abstract)

In sctyner/dplyr050: A Grammar of Data Manipulation

Description

This method shouldn't be called by users - it should only be used by backend implementors who are creating backends that extend the basic sql behaviour.

Usage

tbl_sql(subclass, src, from, ..., vars = attr(from, "vars"))

Arguments

subclass	name of subclass
...	needed for agreement with generic. Not otherwise used.
vars	If known, the names of the variables in the tbl. This is relatively expensive to determine automatically, so is cached throughout dplyr. However, you should usually be able to leave this blank and it will be determined from the context.
