Invalid sql statements generated with '(single quotes) in field names.

What steps will reproduce the problem?
1. Create a table object
2. Specify the schema and table name using
    using_table_options(schema='myschema')
    using_options(tablename='mytable')
3. Query table object with all

What is the expected output? What do you see instead?
A select statement should be generated with the form myschema.mytable.field. 
Instead a select statement is created with the form myschema.mytable.'field' . 
This causes the statement to fail with the following error:
