需要从MySql结果中修剪新行

Question

我正在使用MySql工作台备份来自Magento数据库的数据。下面是我使用的查询：

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') 

我真正需要做的是剥离新的线条勾勒出地址1场的，因为它打破了我使用CSV解析器。我试过了：

TRIM(\n FROM Address1.value) as Address1 

对查询的第四行，但那是不成功的。我对MySql的知识显然是有限的，任何帮助都会为我节省几个小时来删除新行。

Answer 1

用不同的路线前进。

摆脱装饰和东西

TRIM(\n FROM Address1.value) as Address1 

将被

table.address1 as Address1 

然后所有的联接添加一个WHERE子句，并设置到其中，你会考虑新的日期之后。

会是这样的：

WHERE date =< 2016-04-28 

这应该让这个它只会显示与日期列比今天的日期的行。

哦，还有，如果你实际上不想使用日期列，但你知道什么ID号的新行开始，你总是可以使用它。它应该是相同的语法，但具有不同的列

希望有所帮助。如果你需要更多的帮助，请让我知道

另一件需要注意的是它建议有小写的表和列名。所以我会做这些一些编辑，以及与确保一切是因为SQL承认资本

你可以从Address1.value场运行

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

，并删除所有“\ n”小写之后运行您的查询。

另一个解决方案是在你的SELECT语句中使用REPLACE()：

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
