Now we have Query class with methods: order, desc, limit, offset.
See PR: #135
Examples:

metasql/test/sql.js

Lines 46 to 69 in a4960d3

    
           metatests.test('Query.limit/offset', async (test) => {

             test.strictEqual(res1.length, 3); 
        
             test.strictEqual(res1[0].name, 'Beijing');
