我将以下代码转换为视图。但是我无法在视图中声明varchar。
任何人都可以建议绕道而行吗?
Sql代码 -
DECLARE @PROJECTNUMBER VarChar
SELECT SUM(PAFeeAmount) FeeAmount
FROM PA02101
WHERE PAPROJNUMBER = @PROJECTNUMBER
谢谢,

如果您需要变量,请使用表值函数:

如果您尝试将参数传递给VIEW
,则无法执行此操作。在视图中选择时,只需使用分组依据进行以下视图,然后进行过滤。
CREATE VIEW myView
AS
SELECT PAPROJNUMBER, SUM(PAFeeAmount) FeeAmount
FROM PA02101
GROUP BY PAPROJNUMBER
--Select like below. (may be passing it to a stored procedure)
declare @projectNumber varchar(50) --remember to give a length
select * from myView
where projectNumber = @projectNumber

尝试创建inline table-valued
功能。例如:
CREATE FUNCTION dbo.fxSample(@PROJECTNUMBER VARCHAR(20))
RETURNS TABLE
AS
RETURN
(
SELECT SUM(PAFeeAmount) FeeAmount
FROM PA02101
WHERE PAPROJNUMBER = @PROJECTNUMBER
)
-- Then call like this, just as if it's a table/view just with a parameter
SELECT * FROM dbo.fxSample('hello')
