TSQL替换我的存储过程字符串参数

Question

我的问题：一旦我收到参数值，我想修改内容。

E.g.一个字符串参数值是：FullName,Address,Category

我想改变FullName到l.FullName和Category到c.Category并保持休息一样。

ALTER PROCEDURE [dbo].[TableA] @ColNames VARCHAR(1000) 
AS 
BEGIN 
    //I want to modify the contents of @ColNames here 

Answer 1

这个怎么样？

select @ColNames = replace(@ColNames, 'FullName', 'l.FullName'); 
select @ColNames = replace(@ColNames, 'Category', 'c.Category'); 

Answer 2

是的，你可以这样做 - @ColNames是一个变量 - 你可以操纵它的内容。

ALTER PROCEDURE [dbo].[TableA] @ColNames VARCHAR(1000) 
AS 
BEGIN 
    -- I want to modify the contents of @ColNames here 
SET @ColNames = REPLACE(@ColNames, "FullName", "l.FullName") 
SET @ColNames = REPLACE(@ColNames, "Category", "c.Category") 

Answer 3

ALTER PROCEDURE [dbo].[TableA] @ColNames VARCHAR(1000) 
AS 
BEGIN 
    SET 
     @ColNames = REPLACE(@ColNames, 'FullName', 'l.FullName') 
     ; 
    SET 
     @ColNames = REPLACE(@ColNames, 'Category', 'c.Category') 
     ; 

Answer 4

declare 
@ColNames varchar(50) 


select @ColNames = replace(@ColNames, 'FullName', 'l.FullName'); 
select @ColNames = replace(@ColNames, 'Category', 'c.Category');
