如何在 SQL Server 列中的两个字符串之间选择一个字符串？

Question

我想获取表列中两个字符串之间的字符串。如何选择列？我已经写了两边的字符串。谁能帮助我如何在此处包含带有字符串的列名称？

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

这是一种提取两个固定字符串之间的文本的方法。不太确定您对 @Text 变量做了什么，所以我用它作为下面的示例。

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'
