Reasoning: The question is asking about price indices for housing specifically in NYC boroughs. In the story, it is asking for information that would be most directly related to borough-level real estate data, as opposed to city-wide or neighborhood-specific information. The focus is on housing prices, which are a key component of real estate indices.

- partitons: The data for NYCRealEstateIndices_2018_09 is partitioned into 2 tables
  table_names:
  - stg_priceIndex_condos_co_ops_homes_NYC_2018_09
  - stg_rentIndex_condos_co_ops_homes_NYC_2018_09
  table_desc: The table shows price and rent indices for NYC condos, co-ops, and homes.
    Each index uses a repeat-sales method of comparing the sales prices of the same
    properties. It includes monthly data starting from 1995. The price index partition
    has columns for date, overall NYC index, month-over-month change, and year-over-year
    change. The rent index likely has a similar structure. Both partitions focus on
    September 2018 data.

🧠 Explanation: The available data is sufficient to answer the business question "What are the price indices for housing in NYC boroughs?". The NYCHousingPriceIndices dataset contains price indices for various NYC neighborhoods and boroughs, which directly addresses the question. This dataset includes 15 partitions, each representing a different area of NYC, including parts of Manhattan, Brooklyn, and Queens. The data includes average sales prices, month-over-month changes, and year-over-year changes, which can provide a comprehensive view of housing price indices across NYC boroughs.
💡 Instruction to write SQL: 1. Select relevant tables from the NYCHousingPriceIndices dataset. Each table represents a different area of NYC. 2. For each table, select the date_, average_sales_price, month_over_month_change, and year_over_year_change columns. 3. Use UNION ALL to combine the results from all tables into a single result set. 4. Group the results by borough. This may require adding a CASE statement to map each area to its corresponding borough. 5. Calculate average price indices for each borough using AVG() function. 6. Order the results by borough for easy reading. 7. Optionally, filter for a specific time period if needed.

🤓 We've planned the join: To execute the SQL, no joins are needed between the tables. Instead, the approach uses UNION ALL to combine results from all tables vertically. A CASE statement may be needed to map each area to its corresponding borough for grouping. The 'date_' column can be used for any time-based filtering if needed.

🤔 Reasoning for column selection: Based on the SQL approach and join description provided, we need to select the same columns from all tables to create a unified result set using UNION ALL. The necessary columns are: 1. date_: Required for potential time-based filtering and grouping. 2. average_sales_price: Needed for calculating average price indices for each borough. 3. month_over_month_change: Part of the required output. 4. year_over_year_change: Part of the required output. We don't need any columns specifically for joins as the approach uses UNION ALL instead. However, we'll need to add a borough column in the query using a CASE statement based on the table name, which isn't an existing column in the tables.
