How many customers are based in London in the CUSTOMER table?
{
    "explanation": "I finalized the SQL query by analyzing the schema and context provided. The question asks for the number of customers based in London in the CUSTOMER table. I used the CUSTOMER table and filtered the results based on the WORKING_AREA column, which is the country column in this case. I used the LOWER function with the LIKE operator to match the country names with 'london'.",
    "query" : "SELECT COUNT(c.CUST_CODE) AS COUNT_OF_CUSTOMERS FROM CUSTOMER c WHERE LOWER(c.WORKING_AREA) LIKE '%london%'",
    "operation_kind" : "aggregation",
    "schema": "CUSTOMER",
    "confidence" : "100",
    "general_message": "Here is the count of customers based in London",
    "main_entity" : "customer"
