Question

大家好我有以下mysql查询，我需要输出到一个表，以便通过电子邮件发送给客户！我只需要将结果格式化为表格。

 select division_name,
     count(*) "Total Cases on CTS",
     sum(if(Date(Filing_Date) = DATE_SUB(curdate(), INTERVAL 1 DAY), 1,0)) "entered yesterday",
     sum(if(DATE(Filing_date) = curdate(), 1, 0)) 'entered today',
     sum(if(YEAR(filing_date) = YEAR(curdate()) AND Month(filing_date) = Month(curdate()), 1,0)) "entered this month",
     sum(if(YEAR(filing_date) = YEAR(DATE_SUB(curdate(), INTERVAL 1 MONTH)) AND Month(filing_date) = Month(DATE_SUB(curdate(), INTERVAL 1 MONTH)), 1,0)) as entered_last_month
     from cases2v
     where court_rank_name like 'High Court'
          OR court_rank_name like 'Magistrate Court'
     group by division_name";

我已经尝试将查询输出到csv文件，然后在linux（Centos 7）中使用ssconvert转换为excel并使用postfix发送电子邮件，输出文件看起来不太好......它缺少表格头。

我在考虑使用shell脚本将查询输出到数组然后遍历结果以创建表格会更好更快但我不知道怎么做！这是我试过的

dbquery=$(mysql -u user -ppass -e "use db_name; select division_name, count(*) "Total Cases on CTS", sum(if(Date(Filing_Date) = DATE_SUB(curdate(), INTERVAL 1 DAY), 1,0)) "entered yesterday", sum(if(DATE(Filing_date) = curdate(), 1, 0)) 'entered today', sum(if(YEAR(filing_date) = YEAR(curdate()) AND Month(filing_date) = Month(curdate()), 1,0))  "entered this month", sum(if(YEAR(filing_date) = YEAR(DATE_SUB(curdate(), INTERVAL 1 MONTH)) AND Month(filing_date) = Month(DATE_SUB(curdate(), INTERVAL 1 MONTH)), 1,0)) as entered_last_month from cases2v  where court_rank_name like 'High Court' OR court_rank_name like 'Magistrate Court' group by division_name;")

array=($(for i in $dbquery; do echo $i; done ))

您可以尝试使用union将列标题添加到结果中。另外，请注意你的报价。我对列和表使用反引号，对字符串使用单引号，只是为了清楚并避免混淆。你有几个地方在双引号中有双引号

SELECT 
    'division_name' AS `division_name`,
    'Total Cases on CTS' AS `Total Cases on CTS`,
    'entered yesterday' as `entered yesterday`,
    'entered today' AS `entered today`,
    'entered this month' AS `entered this month`,
    'entered_last_month' AS `entered_last_month`
UNION
SELECT 
    `division_name`,
    count(*) AS `Total Cases on CTS`,
    sum(if(Date(Filing_Date) = DATE_SUB(CURDATE(), INTERVAL 1 DAY), 1,0))  AS `entered yesterday`,
    sum(if(DATE(Filing_date) = CURDATE(), 1, 0)) AS `entered today`,
    sum(if(YEAR(filing_date) = YEAR(CURDATE()) AND Month(filing_date) = Month(CURDATE()), 1,0)) AS `entered this month`,
    sum(if(YEAR(filing_date) = YEAR(DATE_SUB(CURDATE(), INTERVAL 1 MONTH)) AND Month(filing_date) = Month(DATE_SUB(CURDATE(), INTERVAL 1 MONTH)), 1,0)) as `entered_last_month`
FROM cases2v
WHERE court_rank_name LIKE 'High Court'
    OR court_rank_name LIKE 'Magistrate Court'
GROUP BY division_name";

输出mysql查询到shell脚本
