Database 查询grafana中有多个值，带有LIKE to Postgres

我使用Grafana变量系统在查询中创建过滤器，但是当我选择多个值时，查询不起作用，如何将LIKE与包含多个值的外部变量一起使用？示例：

“1”、“2”和“3”

生成变量值的查询：

输出查询：

• srv1.company.com.br
• srv2.company.com.br
• srv3.company.com.br

在面板上的查询：

已发送到数据库的查询：

输出为空

注意：如果删除条件中的过滤器

like

，我将获得值

select distinct (regexp_matches(hosts, 'name=(.*)', 'i'))[1] from metrics

SELECT
    timestamp AS time,
    avg(CAST(value AS int)) as Total
FROM
    metrics
WHERE
    AND hosts LIKE '%' || ($host) || '%'
GROUP BY timestamp

SELECT
    timestamp AS time,
    avg(CAST(value AS int)) as Total
FROM
    metrics
WHERE
    AND hosts LIKE '%' || ('srv1.company.com.br','srv2.company.com.br','srv3.company.com.br') || '%'
GROUP BY timestamp
