Get SQL Computed Column Inserted Value

问题

My Table Structure as follow,

CREATE TABLE tbl_Info
(
    [SSEID]         BIGINT              NOT NULL    IDENTITY(1,1),
    [ShortenKey]    AS ConvertToBase([SSEID]),
    [Title]         VARCHAR(500)        NULL,       
)

ConvertToBase Function as Follow,

CREATE FUNCTION ConvertToBase(@Number BIGINT)
RETURNS VARCHAR(15)
AS 
BEGIN
      // implementation
END

I need to get the generated [ShortenKey] value after INSERT query in sp. how to do this ?

回答1:

Use the OUTPUT clause?

INSERT tbl_Info (Title)
OUTPUT INSERTED.ShortenKey
VALUES ('new title')

Note: may not work with computed columns says MSDN, if I read it correctly.

回答2:

Use SCOPE_IDENTITY to get the new identity value. Then query the newly inserted row.

SELECT ShortenKey
FROM dbo.tbl_Info
WHERE SSEID = SCOPE_IDENTITY()

回答3:

SELECT ShortenKey
FROM dbo.tbl_Info
WHERE SSEID = SCOPE_IDENTITY()
