Question

我的问题：一旦收到参数值，我想修改内容。

E.g。字符串参数值为：FullName,Address,Category

我想将FullName更改为l.FullName，将Category更改为c.Category，其余部分保持不变。

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');
