mysql - 在 Plotalot 中使用 BETWEEN 子句

Question

尝试创建排行榜并使用 Plotalot 图表进行显示。我正在使用 BETWEEN 子句，但我似乎没有得到我期望的结果，即......没有结果!将不胜感激对此的支持。

代码是

SELECT FieldName, COUNT(FieldValue) AS "Total" 
FROM jos_rsform_submission_values 
WHERE FieldName LIKE'Goals' AND "Total" BETWEEN 1 AND 20 ORDER BY Total DESC

Answer 1

我希望您已经知道使用 WHERE 语法应该有结果。

尝试不使用“”

SELECT FieldName, COUNT(FieldValue) `Total`
FROM jos_rsform_submission_values 
WHERE FieldName LIKE 'Goals' AND Total BETWEEN 1 AND 20 ORDER BY Total DESC

也可以使用子查询来完成

SELECT * FROM
(    
SELECT FieldName, COUNT(FieldValue)  `Total`
FROM jos_rsform_submission_values 
WHERE FieldName LIKE 'Goals' 
) Sub WHERE Sub.Total BETWEEN 1 AND 20 
ORDER BY Sub.Total DESC

尝试此查询以确保匹配项总数在 1 到 20 之间

    SELECT FieldName, COUNT(FieldValue)  `Total`
    FROM jos_rsform_submission_values 
    GROUP BY FieldName
