コンマで区切られた複数のMySqlクエリの出力

Question

テーブルに対して複数のクエリを実行し、コンマ区切り形式で出力を取得する必要があります。ここに私が書いたスクリプトですが、各MySQLクエリの出力を1行ずつ表示します。

#!/bin/bash 
mysql -uuser -p7pas db -e "select number from hits_log where created_at between '2017-04-07 00:00:00' and '2017-04-08 00:00:00'| while read number; do 

mysql -uuser -ppas db -e "select number,count(1) as total_hits from hits_log where number='$number' and time between '2017-04-07 00:00:00' and '2017-04-08 00:00:00' ; select count(1) as xxx from hits_log where number_type='some_value' and old_number='$number' and time between '2017-04-07 00:00:00' and '2017-04-08 00:00:00';" 
done 

私が手出力が所望の出力は、あなたがループを必要としない

number total_hits xxxx 

12345 4 0 

Answer 1

ある

number total_hits 

12345 4 

xxxx 

0 

です。 2つのクエリを結合するだけです。

mysql -e " 
    SELECT l1.number, COUNT(*) AS total_hits, IFNULL(l2.xxx, 0) AS xxx 
    FROM hits_log AS l1 
    LEFT JOIN (
     SELECT old_number, COUNT(*) AS xxx 
     FROM hits_log 
     WHERE number_type='some_value' 
     AND time between '2017-04-07 00:00:00' and '2017-04-08 00:00:00' 
     GROUP BY old_number) AS l2 
    ON l1.number = l2.old_number 
    WHERE time between '2017-04-07 00:00:00' and '2017-04-08 00:00:00' 
    GROUP BY l1.number" 

あなたが本当にループ内の単一$numberのためのクエリを実行する必要がある場合でも、単一の行にそれらを得るために、これらの2つのクエリを結合することができます。

mysql -e " 
    select number,count(1) as total_hits, xxx 
    from hits_log 
    cross join (
     select count(1) as xxx 
     from hits_log 
     where number_type='some_value' 
     and old_number='$number' 
     and time between '2017-04-07 00:00:00' and '2017-04-08 00:00:00' 
    ) as x 
where number='$number' 
and time between '2017-04-07 00:00:00' and '2017-04-08 00:00:00' ;"
