我想将具有特定列的表导出为CSV文件。 （我的数据库名称是：myDatabaseXYZ，用户名是：myUsername1，密码是：mypassword1234，数据库是localhost，表名是GDPR_Violation_Actions）
但是以下不起作用：
输入：
$ mysql -B -u myUsername1 -p mypassword1234 myDatabaseXYZ
-h localhost
-e "SELECT id,GDPR_PROOF,email,telephone FROM GDPR_Violation_Actions;" \
| sed "s/'/\'/;s/\t/\",\"/g;s/^/\"/;s/$/\"/;s/\n//g"
输出：

答案 0 :(得分：2)
假设你确实完全复制了这些命令，那么你输出的问题可能是你在行继续符space之后的另外两个"\"字符（应该是最后的事情就行了。）
删除那些spaces，它应该有效。
