Grafana-如何为Mysql数据源创建sql查询部分变量/宏

我在Grafana中有以下查询，它由MySql数据源支持

SELECT
  $__timeGroupAlias(ts,$__interval),
  sum(total) AS "total"
FROM hp
WHERE
  $__timeFilter(ts) 
  AND customer_type IN ($CustomerType) AND age IN ($age) AND gender IN ($gender)
GROUP BY 1
ORDER BY $__timeGroup(ts,$__interval)

仪表板中有多个singleStat/panel/Graph，它们使用不同的select参数，但所有这些参数中的WHERE条件保持不变

我希望将条件作为单独的常量变量保留，以便在每个查询中只添加该变量

我试图这样构建我的查询

SELECT
  $__timeGroupAlias(ts,$__interval),
  sum(total) AS "total"
FROM hp
$where_condition
GROUP BY 1
ORDER BY $__timeGroup(ts,$__interval)

SELECT
  UNIX_TIMESTAMP(ts) DIV 900 * 900 AS "time",
  sum(total) AS "total"
FROM hp
ts BETWEEN FROM_UNIXTIME(1548311714) AND FROM_UNIXTIME(1548398114) 
AND customer_type IN ($CustomerType) AND age IN ($age) AND gender IN ($gender)
GROUP BY 1
ORDER BY UNIX_TIMESTAMP(ts) DIV 900 * 900

并声明

where_condition

为

where$\u时间过滤器（ts）和客户输入（$CustomerType）和年龄输入（$age）和性别输入（$gender）

但查询失败，因为内部变量（$CustomerType、$age、$gender）没有由查询生成器解析，生成的查询如下所示

SELECT
  $__timeGroupAlias(ts,$__interval),
  sum(total) AS "total"
FROM hp
$where_condition
GROUP BY 1
ORDER BY $__timeGroup(ts,$__interval)

SELECT
  UNIX_TIMESTAMP(ts) DIV 900 * 900 AS "time",
  sum(total) AS "total"
FROM hp
ts BETWEEN FROM_UNIXTIME(1548311714) AND FROM_UNIXTIME(1548398114) 
AND customer_type IN ($CustomerType) AND age IN ($age) AND gender IN ($gender)
GROUP BY 1
ORDER BY UNIX_TIMESTAMP(ts) DIV 900 * 900

是否有办法解决包含在其他变量中的变量。或者是否有其他方法可以将包含变量的查询部分外部化？

常量

变量类型只生成静态字符串。它没有替代任何变量。切换到

query

类型并使用MySQL返回字符串，它将为您的

where\u条件变量提供精确的字符串值。查询：

SELECT 'WHERE $__timeFilter(ts) AND customer_type IN ($CustomerType) AND age IN ($age) AND gender IN ($gender)'

IMHO：变量替换也适用于
常量
类型。您可以为此打开功能请求。
我的报价也有问题，以下是我的解决方案，它支持“全部”和多个选定项：

SELECT '
task_run_table.is_system = false 
AND 
(
    ''__all__'' = ''${user:raw}''
    OR 
    task_run_table.user  = any ( string_to_array(''${user:raw}'', '','')::text[])
)
AND 
(
    ''__all__'' = ''${job:raw}''
    OR 
    task_run_table.job_name  = any ( string_to_array(''${job:raw}'', '','')::text[])
)
' 

All
值已被重写为
\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu。
它是这样使用的：

SELECT 
  $__timeGroup(task_run_table.start_time, '$interval', NULL),
  task_run_table.name AS metric,
  COUNT(*) AS value
FROM
  task_run_table
WHERE 
  $__timeFilter(task_run_table.start_time) 
  AND 
  ${default_filter:raw}
  AND 
  task_run_table.state = $state
GROUP BY time, task_run_table.name
ORDER BY time, value DESC


您对
where_condition
使用了哪种变量类型？您的Grafana版本是什么？Grafana版本=v5.4.3，我对
where_condition
使用了常量类型。它有效。像这样使用这个变量时，我必须禁用引号
${where\u condition:csv}
。我将提出同样的功能要求。
