带有多级子查询的Sql查询

Question

I have an SQL query to get info from a kindergarten presence form inside a joomla website and do some maths to know how much the kids parent should pay each week then sum it to know how much for the tax receipt.

When I use just one kid I get the correct amount, but as soon as I add the second the numbers don't add up with both kids.

Here is the request:

SELECT
    SUM(t1.test1) AS t1,
    SUM(t2.test2) AS t2
FROM
(
    SELECT
        (COUNT(josnh_facileforms_records.id) * sal1.salaire1) AS test1,
        josnh_facileforms_subrecords.record
    FROM josnh_facileforms_records,
         josnh_facileforms_subrecords
    LEFT JOIN
    (
        SELECT
            LEFT(josnh_facileforms_subrecords.value, 5) AS salaire1,
            josnh_facileforms_subrecords.record AS records1
        FROM josnh_facileforms_records,
             josnh_facileforms_subrecords
        WHERE josnh_facileforms_records.user_id = [id]
              AND josnh_facileforms_records.form = 24
              AND josnh_facileforms_records.id = josnh_facileforms_subrecords.record
              AND josnh_facileforms_subrecords.name LIKE 'enfant1'
        GROUP BY
            josnh_facileforms_subrecords.record
    ) AS sal1 ON sal1.records1 = josnh_facileforms_subrecords.record
    WHERE josnh_facileforms_records.user_id = [id]
          AND josnh_facileforms_records.form = 24
          AND josnh_facileforms_records.id = josnh_facileforms_subrecords.record
          AND josnh_facileforms_subrecords.name LIKE '%di1'
          AND josnh_facileforms_subrecords.value = 'RG'
    GROUP BY
        josnh_facileforms_subrecords.record
) AS t1,
(
    SELECT
        (COUNT(josnh_facileforms_records.id) * sal2.salaire2) AS test2,
        josnh_facileforms_subrecords.record
    FROM josnh_facileforms_records,
         josnh_facileforms_subrecords
    LEFT JOIN
    (
        SELECT
            LEFT(josnh_facileforms_subrecords.value, 5) AS salaire2,
            josnh_facileforms_subrecords.record AS records2
        FROM josnh_facileforms_records,
             josnh_facileforms_subrecords
        WHERE josnh_facileforms_records.user_id = [id]
              AND josnh_facileforms_records.form = 24
              AND josnh_facileforms_records.id = josnh_facileforms_subrecords.record
              AND josnh_facileforms_subrecords.name LIKE 'enfant2'
        GROUP BY
            josnh_facileforms_subrecords.record
    ) AS sal2 ON sal2.records2 = josnh_facileforms_subrecords.record
    WHERE josnh_facileforms_records.user_id = [id]
          AND josnh_facileforms_records.form = 24
          AND josnh_facileforms_records.id = josnh_facileforms_subrecords.record
          AND josnh_facileforms_subrecords.name LIKE '%di2'
          AND josnh_facileforms_subrecords.value = 'RG'
    GROUP BY
        josnh_facileforms_subrecords.record
) AS t2;

Can I get a second look at this?

好吧，这是一个新手问题，我太专注于子查询，以至于忘记将 FROM 标签中的子查询与左标签链接起来。
