推荐答案

您可以这样做.

--Create a dummy TABLE to generate a SEQUENCE. No actual records will be stored.
CREATE TABLE SequenceTABLE
(
    ID BIGINT IDENTITY
);
GO

--This procedure is for convenience in retrieving a sequence.
CREATE PROCEDURE dbo.GetSEQUENCE ( @value BIGINT OUTPUT)
AS
    --Act like we are INSERTing a row to increment the IDENTITY
    BEGIN TRANSACTION;
    INSERT SequenceTABLE WITH (TABLOCKX) DEFAULT VALUES;
    ROLLBACK TRANSACTION;
    --Return the latest IDENTITY value.
    SELECT @value = SCOPE_IDENTITY();
GO

--Example execution
DECLARE @value BIGINT;
EXECUTE dbo.GetSEQUENCE @value OUTPUT;
SELECT @value AS [@value];
GO
