Question

我有两个MySQL查询，可以提供我正在寻找的结果。我最终想要将这两个查询结合起来制作一张桌子并且我被卡住了。

QUERY 1：

SELECT scoc.isr, outcome_concept_id, concept_name as outcome_name
FROM standard_case_outcome AS sco INNER JOIN concept AS c
ON sco.outcome_concept_id = c.concept_id
INNER JOIN standard_case_outcome_category AS scoc
ON scoc.isr = sco.isr
WHERE scoc.outc_code = 'CA'

结果1：

QUERY 2：

SELECT scoc.isr, drug_seq, concept_id, concept_name as drug_name
FROM standard_case_drug AS scd INNER JOIN concept AS c
ON scd.standard_concept_id = c.concept_id
INNER JOIN standard_case_outcome_category AS scoc
ON scoc.isr = scd.isr
WHERE scoc.outc_code = 'CA'

结果2：

期望的结果：

我很确定我可以弄清楚如何使用Python / pandas来做这件事，但我想知道是否有（a）方法来做这个MySQL（b）使用MySQL做任何好处。

**如果你有点好奇，this is the entire dataset。

这里是相关表格的数据库结构：

Answer 1

这可以让你得到理想的结果。

SELECT
    `scoc`.`isr`                AS `isr`,
    `sco` .`outcome_concept_id` AS `outcome_concept_id`,
    `c1`  .`concept_name`       AS `outcome_name`,
    `scd` .`drug_seq`           AS `drug_seq`,
    `scd` .`concept_id`         AS `concept_id`,
    `c2`  .`concept_name`       AS `drug_name`
FROM
    `standard_case_outcome` AS `sco`
INNER JOIN
    `concept` AS `c1`
    ON
        `sco`.`outcome_concept_id` = `c1`.`concept_id`
LEFT JOIN
    `standard_case_drug` AS `scd`
    ON
        `sco`.`isr` = `scd`.`isr`
INNER JOIN
    `concept` AS `c2`
    ON
        `scd`.`outcome_concept_id` = `c2`.`concept_id`
INNER JOIN
    `standard_case_outcome_category` AS `scoc`
    ON
        `scoc`.`isr` = `sco`.`isr`
WHERE
    `scoc`.`outc_code` = 'CA'

修改

请注意，我遗漏了concept表，因为您没有从中选择任何内容，或者使用它过滤结果。

第二次编辑

已更新，以包含concept表格。更新后的问题表明，实际上需要SELECT。

第三次编辑

需要分别为concept和name选择sco。scd。

多个MySQL JOIN和重复的单元格
