Question

如何在MySQL 5.5中设置多个转义字母。当我在MySQL 5.0.22中设置多个字母（'\“，\ r，\ 015 \ n，\ n，\ b'）时没关系，但是在MySQL 5.5.28中给出了错误代码' ERROR 1083 （42000）：字段分隔符参数不是预期的;请查看手册' 我的查询如下，

select ID,MSISDN,IFNULL(TITLE,''),IFNULL(SECONDARY_TITLE,''),IFNULL (NAME,''),IFNULL(ACTIVATION_DATE,''),IFNULL(CREDIT_EXPIRY_DATE,''),
IFNULL(FIRST_VOICE_CALL_DATE,''),IFNULL(FIRST_SMS_DATE,''),IFNULL(FIRST_MMS_DATE,''),
IFNULL(FIRST_WAP_DATE,''),IFNULL(FIRST_TOPUP_DATE,''),IFNULL(TOTAL_USAGE,''),
IFNULL(TOTAL_TOPUP_AMOUNT,''),IFNULL(TOTAL_TOPUP_COUNT,''),IFNULL(LAST_TOPUP_DATE,''),
IFNULL(ACCOUNT_BALANCE,''),IFNULL(TARIFF_PLAN,''),IFNULL(DATE_OF_BIRTH,''),IFNULL(ADDRESS,''),
IFNULL(COUNTRY,''),IFNULL(CITY,''),IFNULL(POSTCODE,''),IFNULL(IC_NUMBER,''),
GENDER,IFNULL(FIXED_LINE_PHONE,''),IFNULL(EMAIL,''),IFNULL(PROFESSION,''),
IFNULL(EMPLOYER_NAME,''),IFNULL(EMPLOYER_ADDRESS,''),IFNULL(EMPLOYER_PHONE_NUMBER,''),
IFNULL(EMPLOYER_FAX_NUMBER,''),IFNULL(SIM_STATE,''),
IFNULL(ADDITIONAL_INFORMATION,'')  INTO OUTFILE '/tmp/SUBSCRIBER_PROFILE.txt'  
FIELDS ESCAPED BY '\",\\r,\\015\n,\\n,\\b' TERMINATED BY '|' 
OPTIONALLY ENCLOSED BY '\"' LINES TERMINATED BY '\n'  FROM  SUBSCRIBER_PROFILE;

但是当我在'escape by'选项中只设置一个字母时，它可以正常工作

请帮我解决这个问题。谢谢， Dhanushka

你的情况下的转义字符应该只是“\”，因为你正在使用\来转义字符。它不是要求你要逃脱的序列列表，只是让它知道它被转义的字符，在这种情况下是\。

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 使用MySQL 5.0.21

mysql> select ID,MSISDN,IFNULL(TITLE,''),IFNULL(SECONDARY_TITLE,''),IFNULL(NAME,''),IFNULL(ACTIVATION_DATE,''),IFNULL(CREDIT_EXPIRY_DATE,''), 
    -> IFNULL(FIRST_VOICE_CALL_DATE,'') ,IFNULL(FIRST_SMS_DATE,''),IFNULL(FIRST_MMS_DATE,''),IFNULL(FIRST_WAP_DATE,''),
    -> IFNULL(FIRST_TOPUP_DATE,''),IFNULL(TOTAL_USAGE,''),IFNULL(TOTAL_TOPUP_AMOUNT,''),IFNULL(TOTAL_TOPUP_COUNT,''),
    -> IFNULL(LAST_TOPUP_DATE,''),IFNULL(ACCOUNT_BALANCE,''),IFNULL(TARIFF_PLAN,''), IFNULL(DATE_OF_BIRTH,''),IFNULL(ADDRESS,''),
    -> IFNULL(COUNTRY,''),IFNULL(CITY,''),IFNULL(POSTCODE,''),IFNULL(IC_NUMBER,''), GENDER,IFNULL(FIXED_LINE_PHONE,''),IFNULL(EMAIL,''),
    -> IFNULL(PROFESSION,''),IFNULL(EMPLOYER_NAME,''),IFNULL(EMPLOYER_ADDRESS,''), IFNULL(EMPLOYER_PHONE_NUMBER,''),
    -> IFNULL(EMPLOYER_FAX_NUMBER,''),IFNULL(SIM_STATE,''),IFNULL(ADDITIONAL_INFORMATION,'')  INTO OUTFILE '/tmp/SUBSCRIBER_PROFILE.txt' 
    ->  ***FIELDS ESCAPED BY '\",\\r,\\015\n,\\n,\\b'*** TERMINATED BY '|' OPTIONALLY ENCLOSED BY '\"' LINES TERMINATED BY '\n'  FROM  SUBSCRIBER_PROFILE;         
*Query OK, 345812 rows affected (7.77 sec*)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 不使用MySQL 5.5.28

mysql> select ID,MSISDN,IFNULL(TITLE,''),IFNULL(SECONDARY_TITLE,''),IFNULL(NAME,''),IFNULL(ACTIVATION_DATE,''),IFNULL(CREDIT_EXPIRY_DATE,''), 
    -> IFNULL(FIRST_VOICE_CALL_DATE,'') ,IFNULL(FIRST_SMS_DATE,''),IFNULL(FIRST_MMS_DATE,''),IFNULL(FIRST_WAP_DATE,''),
