使用MySQL从3张不同表提取列表项并生成报表

Hey there! Let's work through generating your business reports using the BillableDatas table you provided. I notice you mentioned 3 tables total, but only shared this one—feel free to drop the other table structures if you need a more comprehensive report that joins all three!

First, let's recap the structure of your BillableDatas table for clarity:

Below are some common business report queries tailored to this table, which you can adapt or expand once you share the other tables:

1. Daily Billing Summary (Split by Charge Status) #

This report breaks down daily total quantity and total amount, separated by whether the entries are charged or not. Great for tracking daily revenue and outstanding charges.

SELECT
    BIL_Date,
    BIL_Status,
    SUM(BIL_Quantity) AS Total_Quantity,
    SUM(BIL_Rate * BIL_Quantity) AS Total_Amount
FROM BillableDatas
GROUP BY BIL_Date, BIL_Status
ORDER BY BIL_Date ASC;

2. Overall Status Summary #

Get a high-level view of how much has been charged vs. is still outstanding, including total counts and amounts.

SELECT
    BIL_Status,
    COUNT(BIL_Id) AS Total_Entries,
    SUM(BIL_Quantity) AS Total_Quantity,
    SUM(BIL_Rate * BIL_Quantity) AS Total_Amount
FROM BillableDatas
GROUP BY BIL_Status;

3. Rate-Based Billing Breakdown #

If you want to analyze performance across different rates, this query groups data by your BIL_Rate and includes status splits.

SELECT
    BIL_Rate,
    BIL_Status,
    SUM(BIL_Quantity) AS Total_Quantity,
    SUM(BIL_Rate * BIL_Quantity) AS Total_Amount
FROM BillableDatas
GROUP BY BIL_Rate, BIL_Status
ORDER BY BIL_Rate DESC;

Once you share the other two tables (like maybe a client table, service table, etc.), we can adjust these queries to join them and add more context—like linking billable entries to specific clients or services.
