从两个存储过程创建字符串模板

Question

我有两个 return 结果集的存储过程。

如何使用它们填充字符串并更新另一列？

exec getEmailSignatureDetails 'Jane', 'Doe'

exec getFeaturedAccount 'June'

我想将这两个 return 列映射到变量。

然后我想将变量放入一个字符串中。

然后用该字符串更新另一个 table 中的列。

来自getEmailSignatureDetails的输出：

addCity       | addLine     | addSt |  addZip | fName | lName
--------------+-------------+-------+---------+-------+------
San Francisco | 777 SV Lane | CA    |  94016  | Jane  | Doe

来自getFeaturedAccount的输出：

month | img      
------+----------
June  | base64...

我想把它变成像

这样的字符串

Your package has been delivered to 
@fName @lName
@addLine
@addCity @addSt, @addZip
@img

然后使用与名称匹配的字符串更新一列。

如果我理解你的问题，你希望通过宏替换动态填充模板

例子

-- Create some Sample Data
Declare @getEmailSignatureDetails Table ([addCity] varchar(50),[addLine] varchar(50),[addSt] varchar(50),[addZip] varchar(50),[fName] varchar(50),[lName] varchar(50))
Insert Into @getEmailSignatureDetails Values 
 ('San Francisco','777 SV Lane','CA',94016,'Jane','Doe')

Declare @getFeaturedAccount Table ([month] varchar(50),[img] varchar(50))
Insert Into @getFeaturedAccount Values 
 ('June','base64..')



-- Declare the Template
Declare @Template varchar(max) ='
Your package has been delivered to 
@fName @lName
@addLine
@addCity @addSt, @addZip
@img
'

-- Populate the Template
Select @Template = replace(@Template,'@'+Field,Value)
 From ( 
        Select C.*
         From (values (convert(XML,(Select * From  @getEmailSignatureDetails Join  @getFeaturedAccount on [month]='June' For XML Raw ) ) ) ) A(XMLData)
         Cross Apply (
                        Select Field = a.value('local-name(.)','varchar(100)')
                              ,Value = a.value('.','varchar(max)') 
                         From  A.XMLData.nodes('/row')  as C1(n)
                         Cross Apply C1.n.nodes('./@*') as C2(a)
                         Where a.value('local-name(.)','varchar(100)') not in ('Column1','Column2')
                     ) C
     ) A

已更新模板

Your package has been delivered to 
Jane Doe
777 SV Lane
San Francisco CA, 94016
base64..

如果它有助于可视化，子查询是一个 "dynamic" 逆轴并生成以下内容：

Field     Value
addCity   San Francisco
addLine   777 SV Lane
addSt     CA
addZip    94016
fName     Jane
lName     Doe
month     June
img       base64..   -- (presumably would be the image)
