【Foreign keys】

Sales Orders._StoreID=Store Locations.StoreID
Sales Orders._CustomerID=Customers.CustomerID
Sales Orders._SalesTeamID=Sales Team.SalesTeamID
Store Locations.StateCode=Regions.StateCode

    【Question】
    In the West, how many stores are there in the city whose land area is below 20,000,000? "West" is the Region; land area is below 20,000,000 refers to Land Area < 20,000,000

    【Evidence】
    "West" is the Region; land area is below 20,000,000 refers to Land Area < 20,000,000

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT SUM(CASE WHEN T1.Region = 'West' AND T2.`Land Area` < 20000000 THEN 1 ELSE 0 END) FROM Regions AS T1 INNER JOIN `Store Locations` AS T2 ON T2.StateCode = T1.StateCode
