如何提高MySQL存储过程运行20秒
How to improve MySQL stored procedure run for 20 seconds
我有一个存储过程将 运行 持续 20 秒并使 cpu 使用率很高，我在慢查询日志中找到它，此存储过程始终存在并将 运行 15 到 30 秒。我相信这个存储过程导致了 CPU 的高使用率。
所以我试图使用 explain 来获取存储过程的查询计划。而且我不太清楚如何改进这个存储过程。请分享一些关于如何改进存储过程的信息。

改变
WHEN ( SELECT COUNT(x) ... ) > 0
至
WHEN EXISTS( SELECT 1 ... )
此外，改变
CASE WHEN EXISTS (...)
THEN (SELECT ... LIMIT 1)
ELSE LocationName
END
简单
IFNULL( (SELECT ... LIMIT 1), LocationName)
我没看到 CREATE TABLE labels；它需要
INDEX(ObjectID, ObjectName, ColumnName, LanguageCode) -- in any order
我不确定 convert(u.Month, char(2)) 能否在 1 位数的月份内正常工作。
u.Q1 中可以有哪些值？我可能会对 ANDs of ORs.
的那一长串进行优化
这个：
and (
p_approvalStatus is null
or
( big select ) = p_approvalStatus
)
看起来是查询的很大一部分（参见 EXPLAIN）。建议通过拉出 NULL 测试来加快某些调用：
BEGIN
IF (p_approvalStatus IS NULL)
THEN
SELECT ...
FROM ...
WHERE ...
and ( (p_biMonthly1 ... )
-- (skipping the p_approvalStatus stuff)
ELSE
SELECT ...
FROM ...
WHERE ...
and ( (p_biMonthly1 ... )
AND ( big select ) = p_approvalStatus -- (no check for NULL)
END IF
END
可能还有一种方法可以进一步重写 ELSE 部分。
如果我在 PHP 中写这个，我会 "construct" PHP 中的查询，从而消除对 'null' 的所有检查，也许所有'ors' 然后发出更短更简单的查询。
请提供SHOW CREATE TABLE labels，我想了解'644'。
你的 "OR" 条件太疯狂了。即使有括号也一样。第 1-4 节的示例
(p_q1 is null or u.Q1 = p_q1)
or (p_q2 is null or u.Q2 = p_q2)
or (p_q3 is null or u.Q3 = p_q3)
or (p_q4 is null or u.Q4 = p_q4)
如果您为 Q4 提供 null 并包括 Q1、Q2、Q3 的 3 个特定值，您仍将浏览所有记录。因此，请确保您明白您的意思……例如，如果您执行上述操作，是否意味着您只需要第 1-3 季度的数据？如果是这样，您的意思可能是
在哪里
(
-- EVERY Quarter 为空
( p_q1 为空
AND p_q2 为空
AND p_q3 为空
AND p_q4 为空
)
要么
-- 或者，该季度必须与我们提供的特定季度相匹配。
-- 在这里你可以只提供 Q1 和 Q3 并且只提取那两个季度
( u.Q1 = p_q1
或者 u.Q2 = p_q2
或 u.Q3 = p_q3
或 u.Q4 = p_q4
)
)
我已将相同的上下文应用到 HalfYear 1-2、FourMonths 1-3、Quarters 1-4 和 BiMonthly 1-6 的标准中
您在 years/months、from/to 日期的其他热门区域标准也很可怕，可能需要重新考虑，或编辑您的 post 并重新澄清您想要获得的内容与解析 date/time 字段的年份和/或月份部分的所有日期。
至于您来自语言的位置和指示符 table，我已将它们更改为预查询以分别获取 ID 和给定的语言或指示符。因此，为每个语言获取一次语言并左连接它们。然后应用 COALESCE()，您要么获取特定语言（如果存在），要么默认来自指标或位置 table 的语言。
这是包含上述上下文的最终重写

我有一个存储过程将 运行 持续 20 秒并使 cpu 使用率很高，我在慢查询日志中找到它，此存储过程始终存在并将 运行 15 到 30 秒。我相信这个存储过程导致了 CPU 的高使用率。 所以我试图使用 explain 来获取存储过程的查询计划。而且我不太清楚如何改进这个存储过程。请分享一些关于如何改进存储过程的信息。

改变
WHEN ( SELECT COUNT(x) ... ) > 0
至
WHEN EXISTS( SELECT 1 ... )
此外，改变
CASE WHEN EXISTS (...)
THEN (SELECT ... LIMIT 1)
ELSE LocationName
END
简单
IFNULL( (SELECT ... LIMIT 1), LocationName)
我没看到 CREATE TABLE labels；它需要
INDEX(ObjectID, ObjectName, ColumnName, LanguageCode) -- in any order
我不确定 convert(u.Month, char(2)) 能否在 1 位数的月份内正常工作。
u.Q1 中可以有哪些值？我可能会对 ANDs of ORs.
这个：
and (
p_approvalStatus is null
or
( big select ) = p_approvalStatus
)
看起来是查询的很大一部分（参见 EXPLAIN）。建议通过拉出 NULL 测试来加快某些调用：
BEGIN
IF (p_approvalStatus IS NULL)
THEN
SELECT ...
FROM ...
WHERE ...
and ( (p_biMonthly1 ... )
-- (skipping the p_approvalStatus stuff)
ELSE
SELECT ...
FROM ...
WHERE ...
and ( (p_biMonthly1 ... )
AND ( big select ) = p_approvalStatus -- (no check for NULL)
END IF
END
可能还有一种方法可以进一步重写 ELSE 部分。
如果我在 PHP 中写这个，我会 "construct" PHP 中的查询，从而消除对 'null' 的所有检查，也许所有'ors' 然后发出更短更简单的查询。
请提供SHOW CREATE TABLE labels，我想了解'644'。
你的 "OR" 条件太疯狂了。即使有括号也一样。第 1-4 节的示例
(p_q1 is null or u.Q1 = p_q1)
or (p_q2 is null or u.Q2 = p_q2)
or (p_q3 is null or u.Q3 = p_q3)
or (p_q4 is null or u.Q4 = p_q4)
如果您为 Q4 提供 null 并包括 Q1、Q2、Q3 的 3 个特定值，您仍将浏览所有记录。因此，请确保您明白您的意思……例如，如果您执行上述操作，是否意味着您只需要第 1-3 季度的数据？如果是这样，您的意思可能是
在哪里 ( -- EVERY Quarter 为空 ( p_q1 为空 AND p_q2 为空 AND p_q3 为空 AND p_q4 为空 ) 要么 -- 或者，该季度必须与我们提供的特定季度相匹配。 -- 在这里你可以只提供 Q1 和 Q3 并且只提取那两个季度 ( u.Q1 = p_q1 或者 u.Q2 = p_q2 或 u.Q3 = p_q3 或 u.Q4 = p_q4 ) )
我已将相同的上下文应用到 HalfYear 1-2、FourMonths 1-3、Quarters 1-4 和 BiMonthly 1-6 的标准中
您在 years/months、from/to 日期的其他热门区域标准也很可怕，可能需要重新考虑，或编辑您的 post 并重新澄清您想要获得的内容与解析 date/time 字段的年份和/或月份部分的所有日期。
至于您来自语言的位置和指示符 table，我已将它们更改为预查询以分别获取 ID 和给定的语言或指示符。因此，为每个语言获取一次语言并左连接它们。然后应用 COALESCE()，您要么获取特定语言（如果存在），要么默认来自指标或位置 table 的语言。
这是包含上述上下文的最终重写
