+-- Federated Queries Test Case
+-- =====================================================
+-- This test demonstrates the use of ODBCLoader for federated queries
+-- allowing Vertica to query external databases (e.g., MySQL) while
+-- leveraging predicate pushdown and column pruning to minimize data movement
+
+-- Create an External Table in Vertica that acts as a gateway to MySQL
+-- The External Table definition stores metadata about the external source
+-- but does not retrieve any data until queried
+CREATE EXTERNAL TABLE public.epeople (
+    id INTEGER,
+    name VARCHAR(20)
+) AS COPY WITH
+    SOURCE ODBCSource()
+    PARSER ODBCLoader(
+        connect='DSN=MySQL',
+        query='SELECT * FROM testdb.people'
+);
+
+-- Test 1: Query with predicate pushdown
+-- When executing a query with a WHERE clause, ODBCLoader rewrites the original
+-- external query to include the predicate, pushing the filter to the external database
+-- This minimizes the amount of data transferred from MySQL to Vertica
+-- Expected: Only people with id > 100 are retrieved from MySQL
+SELECT * FROM public.epeople WHERE id > 100;
+
+-- Test 2: Query with column pruning
+-- When only specific columns are selected, ODBCLoader optimizes the external query
+-- to fetch only the required columns. Columns not in the Vertica query are replaced
+-- with NULL values to match the External Table schema
+-- Expected: Only id column is fetched from MySQL (name is replaced with NULL)
+SELECT id FROM public.epeople WHERE id > 100;
+
+-- Test 3: Federated join query
+-- Demonstrates joining an external table (MySQL) with a Vertica-managed table
+-- This leverages both databases' query engines for optimal performance
+-- Create a temporary Vertica table for joining
+CREATE TABLE public.employee_status (
+    id INTEGER,
+    status VARCHAR(20)
+);
+
+INSERT INTO public.employee_status VALUES 
+    (1, 'active'),
+    (101, 'inactive'),
+    (102, 'active'),
+    (103, 'inactive');
+
+-- Perform a federated join combining data from MySQL (epeople) and Vertica (employee_status)
+-- The ODBCLoader will push down predicates to MySQL when possible
+SELECT epeople.id, epeople.name, employee_status.status
+FROM public.epeople 
+JOIN public.employee_status ON epeople.id = employee_status.id
+WHERE epeople.id > 100;
+
+-- Test 4: Complex predicate pushdown
+-- Multiple predicates are combined and pushed to the external database
+-- Expected: MySQL executes: SELECT * FROM testdb.people WHERE id > 50 AND id < 150
+SELECT id, name FROM public.epeople WHERE id > 50 AND id < 150;
+
+-- Clean up external and temporary tables
