-- Migration: Add dedicated columns for business info
-- Purpose: Move business data from metadata JSONB to queryable/indexable columns
-- Date: 2026-01-31

-- Add business info columns
ALTER TABLE jobs ADD COLUMN IF NOT EXISTS business_name VARCHAR(500);
ALTER TABLE jobs ADD COLUMN IF NOT EXISTS business_category VARCHAR(255);
ALTER TABLE jobs ADD COLUMN IF NOT EXISTS business_address TEXT;
ALTER TABLE jobs ADD COLUMN IF NOT EXISTS business_rating NUMERIC(3,2);

-- Add indexes for common queries
CREATE INDEX IF NOT EXISTS idx_jobs_business_name ON jobs(business_name);
CREATE INDEX IF NOT EXISTS idx_jobs_business_category ON jobs(business_category);
CREATE INDEX IF NOT EXISTS idx_jobs_business_rating ON jobs(business_rating);

-- Migrate existing data from metadata JSONB to new columns
UPDATE jobs SET
    business_name = metadata->>'business_name',
    business_address = metadata->>'business_address',
    business_rating = CASE
        WHEN metadata->>'rating_snapshot' IS NOT NULL
        THEN (metadata->>'rating_snapshot')::NUMERIC(3,2)
        ELSE NULL
    END
WHERE metadata IS NOT NULL
  AND (business_name IS NULL OR business_address IS NULL OR business_rating IS NULL);

-- Clean up metadata: remove migrated fields (optional - keeps metadata for performance metrics only)
-- Note: We keep the data in metadata for backward compatibility, but new code should use columns
