【问题描述】：

很抱歉发布这么低质量的问题，但我真的很茫然。我无法创建这个存储过程，因为工作台一直告诉我我有语法错误......这两个错误被 *** 包围并且在第 6 行。

当我尝试保存存储过程时，名称在workbench中自动解析为_SYNTAX_ERROR，sql失败。

        LEFT JOIN requests ON requests.glid = gls.id AND requests.costCenter = costCenter AND requests.status = 'approved' AND (SELECT YEAR(ap.start_date) FROM ap WHERE ap.id = requests.ap) = year
        LEFT JOIN budgets ON budgets.gl = gls.id AND budgets.costCenter = costCenter

    GROUP BY gls.id;
END

编辑

这也失败了....

CREATE PROCEDURE fetchBudgetInfo(IN year YEAR, IN costCenter INT(11))
BEGIN
    SELECT gls.id, gls.gl, gls.name AS gl_name, budgets.total as totalBudgeted

    GROUP BY gls.id;
END

【问题讨论】：

你能在 SP 之外作为独立的 sql 运行吗？
当我得到神秘错误（我得到它们）时我会做什么.. 删除选择部分的前半部分.. 看看它是否在 SP 之外编译和运行。然后我继续加一半……直到找到让我死去的那一行。
如果我删除了有问题的行，我会在下一个 3 块中的下一行得到相同的错误。
我试图复制到工作台，但我没有有问题的表。 IFNULL(ROUND(SUM(CASE WHEN requests.ap = (SELECT id FROM ap WHERE ap.ap = 1 AND YEAR(ap.start_date) = year) THEN totalCost ELSE 0 END) / ((SELECT total FROM budgets WHERE costCenter = costCenter AND gl = gls.id AND YEAR(budgets.year) = year)***此处错误（缺少右括号）*** / 12) * 100, 2), 0 此处错误（缺少分号)) AS ap1Ap，在你的代码帖子中......你确实有这个措辞......
我应该指出，这个确切的查询适用于 Windows 机器，而不是 Linux 机器

【解决方案1】：

两个查询都不正确。第一个使用第二个BEGIN（没有结束END），第二个缺少from 子句。

【讨论】：

【解决方案2】：

好的..我在这里所做的是删除所有子选择并替换为常量-因为此时我们不关心答案..我们关心的是运行和返回数据。 () 但保留所有括号等。并将其归结为基本框架。我可以让它回到工作台中。然后我会一次添加一个子选择，以“查看”它是否在子选择上中断或它仍然运行..

Select 

IFNULL(ROUND(SUM(CASE WHEN 1 = (1) THEN 10 ELSE 0 END), 2), 0) AS ap2,
IFNULL(ROUND(SUM(CASE WHEN 1 = (0) THEN 20 ELSE 0 END) / ((1) / 12) * 100, 2), 0) AS ap2Ap

from test.maketable
group by make

这可能会揭示真正的罪魁祸首是什么。
