-- Database Diagnostics and Cleanup Script
-- Run this on your testing server to identify and fix seeding issues

-- ===================================================
-- STEP 1: Check for corrupted/malformed SKUs
-- ===================================================
PRINT 'Checking for corrupted inventory items...'
SELECT
    Id,
    SKU,
    Name,
    CompanyId,
    IsDeleted,
    CreatedAt
FROM InventoryItems
WHERE SKU LIKE '(-PWD-%' OR SKU LIKE '%-PWD-%' AND SKU NOT LIKE '[A-Z]%'
ORDER BY CreatedAt DESC

-- ===================================================
-- STEP 2: Check for duplicate SKUs
-- ===================================================
PRINT 'Checking for duplicate SKUs...'
SELECT
    SKU,
    COUNT(*) as DuplicateCount,
    STRING_AGG(CAST(Id AS VARCHAR), ', ') as IDs
FROM InventoryItems
WHERE IsDeleted = 0
GROUP BY SKU
HAVING COUNT(*) > 1

-- ===================================================
-- STEP 3: Check companies and their codes
-- ===================================================
PRINT 'Checking company data...'
SELECT
    Id,
    CompanyName,
    CompanyCode,
    IsActive,
    IsDeleted,
    SubscriptionPlan
FROM Companies
WHERE IsDeleted = 0
ORDER BY Id

-- ===================================================
-- STEP 4: Check inventory count per company
-- ===================================================
PRINT 'Inventory items per company...'
SELECT
    c.Id as CompanyId,
    c.CompanyName,
    c.CompanyCode,
    COUNT(i.Id) as InventoryItemCount
FROM Companies c
LEFT JOIN InventoryItems i ON c.Id = i.CompanyId AND i.IsDeleted = 0
WHERE c.IsDeleted = 0
GROUP BY c.Id, c.CompanyName, c.CompanyCode
ORDER BY c.Id
