-- =============================================================================
-- Migration: Move Compliance Columns from machines to compliance Table
-- Date: 2025-11-14
-- Purpose: Consolidate compliance-related data into dedicated compliance table
-- =============================================================================

-- STEP 1: Add missing compliance columns to compliance table
-- Note: gecoreload already exists in compliance table (172 records populated)
-- MySQL 5.6 compatible (no IF NOT EXISTS support)

-- Add systemname column
ALTER TABLE compliance ADD COLUMN systemname TEXT NULL COMMENT 'System name for compliance tracking';

-- Add devicedescription column
ALTER TABLE compliance ADD COLUMN devicedescription VARCHAR(1000) NULL COMMENT 'Device description';

-- Add on_ge_network column
ALTER TABLE compliance ADD COLUMN on_ge_network ENUM('Yes','No','N/A') NULL COMMENT 'Whether device is on GE network';

-- Add asset_criticality column
ALTER TABLE compliance ADD COLUMN asset_criticality ENUM('High','Medium','Low','N/A') NULL COMMENT 'Asset criticality level';

-- Add jump_box column
ALTER TABLE compliance ADD COLUMN jump_box ENUM('Yes','No','N/A') NULL COMMENT 'Whether device is a jump box';

-- Add mft column
ALTER TABLE compliance ADD COLUMN mft ENUM('Yes','No','N/A') NULL COMMENT 'Managed File Transfer status';

-- STEP 2: Migrate any existing data from machines to compliance
-- (Current analysis shows 0 records with data in these columns, but script handles it anyway)

INSERT INTO compliance (machineid, systemname, devicedescription, on_ge_network, asset_criticality, jump_box, mft, gecoreload)
SELECT
    m.machineid,
    m.systemname,
    m.devicedescription,
    m.on_ge_network,
    m.asset_criticality,
    m.jump_box,
    m.mft,
    m.gecoreload
FROM machines m
WHERE (
    m.systemname IS NOT NULL OR
    m.devicedescription IS NOT NULL OR
    m.on_ge_network IS NOT NULL OR
    m.asset_criticality IS NOT NULL OR
    m.jump_box IS NOT NULL OR
    m.mft IS NOT NULL OR
    m.gecoreload IS NOT NULL
)
AND NOT EXISTS (
    SELECT 1 FROM compliance c WHERE c.machineid = m.machineid
)
ON DUPLICATE KEY UPDATE
    systemname = COALESCE(VALUES(systemname), compliance.systemname),
    devicedescription = COALESCE(VALUES(devicedescription), compliance.devicedescription),
    on_ge_network = COALESCE(VALUES(on_ge_network), compliance.on_ge_network),
    asset_criticality = COALESCE(VALUES(asset_criticality), compliance.asset_criticality),
    jump_box = COALESCE(VALUES(jump_box), compliance.jump_box),
    mft = COALESCE(VALUES(mft), compliance.mft),
    gecoreload = COALESCE(VALUES(gecoreload), compliance.gecoreload);

-- STEP 3: Drop compliance columns from machines table
-- These belong in the compliance table, not the machines table
-- MySQL 5.6 compatible (separate statements)

ALTER TABLE machines DROP COLUMN systemname;
ALTER TABLE machines DROP COLUMN devicedescription;
ALTER TABLE machines DROP COLUMN on_ge_network;
ALTER TABLE machines DROP COLUMN asset_criticality;
ALTER TABLE machines DROP COLUMN jump_box;
ALTER TABLE machines DROP COLUMN mft;
ALTER TABLE machines DROP COLUMN gecoreload;

-- =============================================================================
-- Verification Queries
-- =============================================================================

-- Check compliance table structure
-- SHOW COLUMNS FROM compliance;

-- Check machines table no longer has these columns
-- SHOW COLUMNS FROM machines WHERE Field IN ('systemname','devicedescription','on_ge_network','asset_criticality','jump_box','mft','gecoreload');

-- Check data migrated successfully
-- SELECT COUNT(*) as compliance_records FROM compliance WHERE systemname IS NOT NULL OR devicedescription IS NOT NULL;

-- Status: Ready to execute
-- Impact: Low - No ASP pages reference these columns, all data already in compliance table
-- Tested: No
