Top Walmart Global Tech SQL Interview Problems & Solutions

Here are realistic SQL problems reflecting the exact domain shapes tested in Walmart Global Tech technical rounds:

Problem 1: Store Inventory Stockout Detection

Business Scenario:
Identify store-item pairs where inventory levels dropped below safety stock for 3 or more consecutive days.

Table Schema:

daily_inventory(store_id, item_id, inventory_date, stock_on_hand, safety_stock_threshold)

Optimal SQL Solution (PostgreSQL):

WITH stockout_days AS (
    SELECT 
        store_id,
        item_id,
        inventory_date,
        stock_on_hand,
        safety_stock_threshold,
        CASE WHEN stock_on_hand < safety_stock_threshold THEN 1 ELSE 0 END AS is_stockout
    FROM daily_inventory
    WHERE inventory_date >= CURRENT_DATE - INTERVAL '30 days'
),
consecutive_counts AS (
    SELECT 
        store_id,
        item_id,
        inventory_date,
        is_stockout,
        SUM(is_stockout) OVER (
            PARTITION BY store_id, item_id 
            ORDER BY inventory_date 
            ROWS BETWEEN 2 PRECEDING AND CURRENT ROW
        ) AS rolling_3day_stockout_count
    FROM stockout_days
)
SELECT DISTINCT 
    store_id,
    item_id
FROM consecutive_counts
WHERE rolling_3day_stockout_count = 3;

Step-by-Step Logic Breakdown:
Uses ROWS BETWEEN 2 PRECEDING AND CURRENT ROW inside a window function to count rolling consecutive stockout flags.
