Question

我正在使用MySql工作台备份Magento数据库中的数据。这是我正在使用的查询：

Select FName.value AS 'FirstName' ,
LName.value AS 'LastName' ,
e.email,
Address1.value AS Address1, 
City.value AS City ,
Province.value as Province ,
Country.value AS 'CountryCode' ,
Zip.value AS Zip ,
Phone.value AS Phone
FROM customer_entity e 
JOIN customer_address_entity ae ON ae.parent_id = e.entity_id 
JOIN customer_entity_int cei ON e.entity_id = cei.entity_id and cei.attribute_id=13 and cei.value=ae.entity_id 
left JOIN customer_address_entity_varchar FName ON ae.entity_id = FName.entity_id        and FName.attribute_id = (select attribute_id from eav_attribute where entity_type_id=2 and attribute_code='firstname')
left JOIN customer_address_entity_varchar LName ON ae.entity_id = LName.entity_id         and LName.attribute_id= (select attribute_id from eav_attribute where entity_type_id=2 and attribute_code='lastname')
left JOIN customer_address_entity_varchar Zip ON ae.entity_id = Zip.entity_id                         and Zip.attribute_id = (select attribute_id from eav_attribute where entity_type_id=2 and attribute_code='postcode')
left JOIN customer_address_entity_varchar City ON ae.entity_id = City.entity_id                      and City.attribute_id= (select attribute_id from eav_attribute where entity_type_id=2 and attribute_code='city')
left JOIN customer_address_entity_varchar Phone ON ae.entity_id = Phone.entity_id           and Phone.attribute_id = (select attribute_id from eav_attribute where entity_type_id=2 and attribute_code='telephone') 
left JOIN customer_address_entity_varchar Province ON ae.entity_id = Province.entity_id and Province.attribute_id = (select attribute_id from eav_attribute where entity_type_id=2 and attribute_code='region')
left JOIN customer_address_entity_varchar Country ON ae.entity_id = Country.entity_id    and Country.attribute_id = (select attribute_id from eav_attribute where entity_type_id=2 and attribute_code='country_id')
left JOIN customer_address_entity_text Address1 ON ae.entity_id = Address1.entity_id     and Address1.attribute_id = (select attribute_id from eav_attribute where entity_type_id=2 and attribute_code='street')

我真正需要做的就是从Address1字段中删除新行，因为它打破了我使用的CSV解析器。我试过了：

TRIM(\n FROM Address1.value) as Address1

在查询的第四行，但这是不成功的。我对MySql的了解显然是有限的，任何帮助都会节省我几个小时删除新行。

Answer 1

你可以删除所有＆＃34; \ n＆＃34;从Address1.value字段运行

UPDATE customer_address_entity_text SET value=REPLACE(value,'\n','')

然后运行您的查询。

另一种解决方案是在REPLACE()声明中使用SELECT：

REPLACE(Address1.value, '\n', '') as Address1

导致

Select FName.value AS 'FirstName' ,
LName.value AS 'LastName' ,
e.email,
REPLACE(Address1.value, '\n', '') AS Address1, 
City.value AS City ,
Province.value as Province ,
Country.value AS 'CountryCode' ,
Zip.value AS Zip ,
Phone.value AS Phone
FROM customer_entity e 
JOIN customer_address_entity ae ON ae.parent_id = e.entity_id 
JOIN customer_entity_int cei ON e.entity_id = cei.entity_id and cei.attribute_id=13 and cei.value=ae.entity_id 
left JOIN customer_address_entity_varchar FName ON ae.entity_id = FName.entity_id        and FName.attribute_id = (select attribute_id from eav_attribute where entity_type_id=2 and attribute_code='firstname')
left JOIN customer_address_entity_varchar LName ON ae.entity_id = LName.entity_id         and LName.attribute_id= (select attribute_id from eav_attribute where entity_type_id=2 and attribute_code='lastname')
left JOIN customer_address_entity_varchar Zip ON ae.entity_id = Zip.entity_id                         and Zip.attribute_id = (select attribute_id from eav_attribute where entity_type_id=2 and attribute_code='postcode')
left JOIN customer_address_entity_varchar City ON ae.entity_id = City.entity_id                      and City.attribute_id= (select attribute_id from eav_attribute where entity_type_id=2 and attribute_code='city')
left JOIN customer_address_entity_varchar Phone ON ae.entity_id = Phone.entity_id           and Phone.attribute_id = (select attribute_id from eav_attribute where entity_type_id=2 and attribute_code='telephone') 
left JOIN customer_address_entity_varchar Province ON ae.entity_id = Province.entity_id and Province.attribute_id = (select attribute_id from eav_attribute where entity_type_id=2 and attribute_code='region')
left JOIN customer_address_entity_varchar Country ON ae.entity_id = Country.entity_id    and Country.attribute_id = (select attribute_id from eav_attribute where entity_type_id=2 and attribute_code='country_id')
left JOIN customer_address_entity_text Address1 ON ae.entity_id = Address1.entity_id     and Address1.attribute_id = (select attribute_id from eav_attribute where entity_type_id=2 and attribute_code='street')

以不同的路线前进。

摆脱修剪和东西

TRIM(\n FROM Address1.value) as Address1

将是

table.address1 as Address1

然后在所有连接之后添加一个WHERE子句并将其设置为您认为是新的日期。

会是这样的：

WHERE date =< 2016-04-28

这应该使它只显示日期列比今天更早的行。

哦，如果你真的不想使用日期专栏，但是你知道新行开始的ID＃，你也可以随时使用它。它应该是相同的语法，但具有不同的列

希望有所帮助。如果您需要更多帮助，请知道

另外需要注意的是，建议将表和列名称设置为小写。所以我也会对这些进行一些编辑，并确保一切都是小写的，因为SQL识别出大写

需要从MySql结果修剪新行
