I want to export a table with specific columns as CSV file. 我想将具有特定列的表导出为CSV文件。 (Where my database name is: myDatabaseXYZ, username is: myUsername1, password is: mypassword1234, database is on localhost, table name is GDPR_Violation_Actions)
(其中我的数据库名称是:myDatabaseXYZ,用户名是:myUsername1,密码是:mypassword1234,数据库在localhost上,表名称是GDPR_Violation_Actions)
But following is not working: 但是以下操作无效:
Input: 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"
Output: 输出:

Assuming you did indeed copy the commands exactly, the problem you are having with the output is probably down to the 2 additional space
characters you have after the line continuation character "\\"
(which should be the very last thing on the line). 假设确实确实确实复制了命令,则输出的问题可能归结为在行连续字符
"\\"
之后的另外两个space
字符(这应该是该行的最后一句话)。
Remove those spaces
and it should work. 删除那些
spaces
,它应该可以工作。
EDIT: 编辑:
$ mysql -B -u myUsername1 -pmypassword1234 myDatabaseXYZ
-h localhost
-e "SELECT id FROM GDPR_Violation_Actions;" | sed "s/'/\'/;s/\t/\",\"/g;s/^/\"/;s/$/\"/;s/\n//g"
