Question

我有以下用MySQL Workbench编写的SQL查询：

SELECT
    t1.sample_id, t1.v_id, t1.s_type as type, t1.s_fusion, t1.e_fusion, CONCAT(t1.cpt1, ":", t1.ppt1) as point1,
    CONCAT(t1.cpt2, ":", t1.ppt2) as point2, t1.s_gene, t1.e_gene, t1.pscore as score, t2.manual_notes
FROM
(
    s_samples
    WHERE sample_id = 'S0001'
) as t1
INNER JOIN
(
    SELECT c.v_id, c.sample_id,
    CONCAT(c.sample_id,"(",e.disease,"): ",c.notes) as manual_notes
    FROM all_samples e
    LEFT JOIN s_samples c
    ON e.sample_id=c.sample_id
    WHERE c.notes is not null AND c.v_id IN
    (SELECT v_id FROM s_samples)
    AND c.sample_id = 'S0001'
) as t2
ON t1.v_id = t2.v_id
ORDER BY t1.v_id;

但是，我收到以下错误：对于该服务器版本，“ SELECT”在此位置无效，期望：'（'，有错误。我对SQL相对较新，所以我不确定为什么得到这个错误以及解决方法。感谢您的见解。

这是无效的SQL：

FROM
(
    s_samples
    WHERE sample_id = 'S0001'
) as t1

也许你打算：

FROM (SELECT s.*
      FROM s_samples s
      WHERE s.sample_id = 'S0001'
     ) t1

当然，这是多余的。您可以只使用该表并将过滤条件放在外部WHERE子句中。

我认为您的错误仅是由于一些一般的混乱而引起的，因为编译器很混乱。

MySQL Workbench：“ SELECT”在此服务器版本的此位置无效，预期：'（'，WITH错误
