Question

我想获取表格列中两个字符串之间的字符串。如何选择列？我写过两边的字符串。任何人都可以帮我如何在这里包含字符串的列名吗？

DECLARE @Text NVARCHAR(MAX)

SELECT 
    SUBSTRING(@Text, CHARINDEX('Manufacturer Name : ', @Text), 
                     CHARINDEX('Manufacturer Part',@text) - CHARINDEX('Manufacturer Name : ', @Text) + LEN('Manufacturer Part')) 
FROM 
    tbIMPACArchiveNew 
WHERE 
    (Description LIKE '%Manufacturer Name: %' 
     OR Description LIKE '%Manufacturer Name : %') 
    AND Description LIKE '%Manufacturer Part%'

预期结果：

Column A                                                       Expected result
Manufacturer Name : ABC Manufacturer Part Number : XVB-C2B4         ABC
Manufacturer Name : DEF Manufacturer Part Number : 3RH1924-1GP11    DEF
Manufacturer Name : ABJ Manufacturer Part Number : FLDP-IOM248-0001 ABJ
Manufacturer Name : HIJ Manufacturer Part Number : L12/5MLLD0035    HIJ
Manufacturer Name : abhkdk Manufacturer Part Number : PEH1083510    abhkdk
Manufacturer Name : 1245 PUMP Manufacturer Part Number : 02-1010-55 1245

Answer 1

对于以下的样本数据

declare @table table (id int identity(1,1), data varchar(1000), descr varchar(1000))

insert into @table values ('Manufacturer Name : Manufacturer 1 Manufacturer Part : asjdfj','First Manufacturer')
insert into @table values ('Manufacturer Name : Manufacturer 2 Manufacturer Part : asjsadfasdfdfj','Second Manufacturer')
insert into @table values ('Manufacturer Name : Manufacturer 3 Manufacturer Part : er6ty','Third Manufacturer')

你可以使用

select substring(data, 
                 charindex('Manufacturer Name : ', data) + len('Manufacturer Name : '),
                 charindex('Manufacturer Part : ',data) - len('Manufacturer Part :') - 2) as Manufacturer_Name
       , descr
from @table

如果您注意到我在子字符串末尾删除了2个字符以消除＆＃39; M＆＃39;来自Manufacturer Part和实际文本之前的空格。您可以使用RTRIM，但我选择了这种方式。

Answer 2

这是一种在两个固定字符串之间提取文本的方法。不完全确定你使用@Text变量做了什么，所以我在下面用它作为例子。

DECLARE @Text NVARCHAR(MAX) = 'blah blah Manufacturer Name : MY NAME Manufacturer Part blah blah'
SELECT SUBSTRING(@Text, CHARINDEX('Manufacturer Name : ', @Text) + LEN('Manufacturer Name : ') + 1, CHARINDEX('Manufacturer Part',@Text) - (CHARINDEX('Manufacturer Name : ', @Text) + 2 + LEN('Manufacturer Name : ')) )

SELECT SUBSTRING(Description, CHARINDEX('Manufacturer Name : ', Description) + LEN('Manufacturer Name : ') + 1, CHARINDEX('Manufacturer Part',Description) - (CHARINDEX('Manufacturer Name : ', Description) + 2 + LEN('Manufacturer Name : ')) )
FROM tbIMPACArchiveNew 
WHERE Description LIKE '%Manufacturer Name : %Manufacturer Part'

Answer 3

我认为这就是你想要的

SELECT SUBSTRING ( Description , 20 , CHARINDEX("Manufacturer Part") - 20)
FROM  tbIMPACArchiveNew;

其中20是＆＃34;制造商名称的长度：＆＃34;

Answer 4

您可以获得第4个空格的索引并删除前20个。

SELECT SUBSTRING ( Description , 20 , instr(Description,' ',1,4 ) - 20)
FROM  tbIMPACArchiveNew;
