SFSQLDriver objects are created by SFSQL() and used to select the correct
method in dbConnect().
They are a superclass of the DBIDriver class, and used purely for dispatch.
# S4 method for SFSQLDriver,ANY dbDataType(dbObj, obj, ...) # S4 method for SFSQLDriver dbIsValid(dbObj, ...) # S4 method for SFSQLDriver dbUnloadDriver(drv, ...) # S4 method for SFSQLDriver dbGetInfo(dbObj, ...)
The "Usage" section lists the class methods overridden by lazysf.
The dbUnloadDriver() method is a null-op.
