BASH MySQL查询到逗号分隔文件 [英] BASH MySQL Query to Comma Separated File

问题描述

我有以下bash脚本：

I have the following bash script:

#!/bin/sh

MYSQLHOST="mysql.remote-host.com"
MYSQLDB="mysqldb"
MYSQLTABLE="table"
MYSQLUSER="user"
MYSQLPASS="pass"
MYSQLDUMP="Report/report.csv"
LOG="Report/report.log"

MYSQLOPTS="--user=${MYSQLUSER} --password=${MYSQLPASS} --host=${MYSQLHOST} ${MYSQLDB}"


echo "Report Begin: $(date)"
 echo "MySQL Dump Begin: $(date)" >> ${LOG}
  echo "SELECT ${MYSQLTABLE}.created_at, ${MYSQLTABLE}.product_options FROM ${MYSQLTABLE} WHERE ${MYSQLTABLE}.product_id=1 ORDER BY ${MYSQLTABLE}.created_at" | mysql ${MYSQLOPTS} > ${MYSQLDUMP}
 echo "MySQL Dump End: $(date)" >> ${LOG}
echo "Report Successful: $(date)"

将MySQL查询转换成 TAB 分隔文件 report.csv 。但是，我需要将其输出到 COMMA 分隔的文件。我意识到我可以创建另一个脚本来将这个文件从TAB转换为COMMA，但是，如果可以，我宁愿保存步骤。所以我怎么能有MySQL转储文件以逗号分隔的格式？

This ouputs my MySQL Query into a "TAB" separated file report.csv. However, I need to have it output to a "COMMA" separated file. I realize I could create another script to convert this file from TAB to COMMA separated, however, I'd rather save the step if I can. So how can I have MySQL dump the file in comma separated format?

编辑：
我发现这个解决方案：如何输出MySQL查询结果以csv格式（到屏幕，而不是文件）？

但我似乎无法使其工作：

However I can't seem to get it to work:

echo "SELECT CONCAT_WS(',', ${MYSQLTABLE}.created_at, ${MYSQLTABLE}.product_options) FROM ${MYSQLTABLE} WHERE ${MYSQLTABLE}.product_id=1 ORDER BY ${MYSQLTABLE}.created_at" | mysql ${MYSQLOPTS} > ${MYSQLDUMP}

无效：

推荐答案

找到一个简单的perl 1-liner似乎做的诀窍：

Found a simple perl 1-liner that seems to do the trick:

perl -F"\t" -lane 'print join ",", map {s/"/""/g; /^[\d.]+$/ ? $_ : qq("$_")} @F '

- Perl脚本

因此，我的脚本中的行如下所示： / p>

So the line in my script looks like this:

        echo "SELECT ${MYSQLTABLE}.created_at, ${MYSQLTABLE}.product_options FROM ${MYSQLTABLE} WHERE ${MYSQLTABLE}.product_id=1 ORDER BY ${MYSQLTABLE}.created_at" | mysql ${MYSQLOPTS} | perl -F"\t" -lane 'print join ",", map {s/"/""/g; /^[\d.]+$/ ? $_ : qq("$_")} @F ' > ${MYSQLDUMP}
