Sql server 2008 快速升级Sql server 2008 R2

我正在尝试使用SP将记录插入到一个表中

CREATE TABLE [dbo].[SHARE_AD_GROUP](
    [SHARE_AD_GROUP_ID] [int] IDENTITY(1,1) NOT NULL,
    [SHARE_ID] [int] NOT NULL,
    [AD_GROUP] [varchar](200) NOT NULL,
    [SHARE_PERMISSIONS] [varchar](65) NULL,

以下哪种方式最好：

1-

二,-

3-Merge=>不知道怎么写

你认为最快的方式是什么？

我认为合并语句比你用两种方式演示的要快。如果您需要了解有关如何在sql server中将合并写入查询的更多信息，请访问以下链接

合并块如下所示，需要将其放入存储过程或任何其他位置

MERGE INTO SHARE_AD_GROUP A
USING (
    SELECT SHARE_AD_GROUP_ID,
        SHARE_ID,
        AD_GROUP,
        SHARE_PERMISSIONS
    FROM SHARE_AD_GROUP
    WHERE SHARE_ID = @shareID AND AD_GROUP = @ownerId
) B ON (A.SHARE_AD_GROUP_ID = B.SHARE_AD_GROUP_ID)
WHEN MATCHED THEN
    UPDATE SET A.SHARE_PERMISSIONS = B.SHARE_PERMISSIONS
WHEN NOT MATCHED THEN
    INSERT (SHARE_PERMISSIONS) VALUES(@sharePermissions);

我敢肯定你已经弄明白了。但有人可能会发现它很有用

ALTER PROCEDURE [dbo].[PROC_INSERT_SHARE_AD_GROUP]
    @shareID int,
    @ownerId varchar(200),
    @sharePermissions varchar(65)
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    MERGE [dbo].SHARE_AD_GROUP AS T
    USING
    (
        SELECT @shareID,@ownerId,@sharePermissions
    ) AS S
    (
        SELECT Share_ID,AD_Group,Share_Permissions
    )
    ON (T.SHARE_ID = S.Share_ID and T.AD_GROUP = S.AD_Group)

    WHEN MATCHED THEN
        UPDATE SET SHARE_PERMISSIONS = S.Share_Permissions

    WHEN NOT MATCHED THEN
        INSERT
            (SHARE_ID,AD_GROUP,SHARE_PERMISSIONS)
        VALUES
            (S.Share_ID,S.AD_Group,S.Share_Permissions)
    ;
END

所有示例都使用两个表target和source，但在我的示例中，我传递的是SP参数。我搜索了，但找不到类似的案例。我已更新了我的答案。您可以查看并根据您的要求进行适当更改吗。可能的副本

MERGE INTO SHARE_AD_GROUP A
USING (
    SELECT SHARE_AD_GROUP_ID,
        SHARE_ID,
        AD_GROUP,
        SHARE_PERMISSIONS
    FROM SHARE_AD_GROUP
    WHERE SHARE_ID = @shareID AND AD_GROUP = @ownerId
) B ON (A.SHARE_AD_GROUP_ID = B.SHARE_AD_GROUP_ID)
WHEN MATCHED THEN
    UPDATE SET A.SHARE_PERMISSIONS = B.SHARE_PERMISSIONS
WHEN NOT MATCHED THEN
    INSERT (SHARE_PERMISSIONS) VALUES(@sharePermissions);

ALTER PROCEDURE [dbo].[PROC_INSERT_SHARE_AD_GROUP]
    @shareID int,
    @ownerId varchar(200),
    @sharePermissions varchar(65)
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    MERGE [dbo].SHARE_AD_GROUP AS T
    USING
    (
        SELECT @shareID,@ownerId,@sharePermissions
    ) AS S
    (
        SELECT Share_ID,AD_Group,Share_Permissions
    )
    ON (T.SHARE_ID = S.Share_ID and T.AD_GROUP = S.AD_Group)

    WHEN MATCHED THEN
        UPDATE SET SHARE_PERMISSIONS = S.Share_Permissions

    WHEN NOT MATCHED THEN
        INSERT
            (SHARE_ID,AD_GROUP,SHARE_PERMISSIONS)
        VALUES
            (S.Share_ID,S.AD_Group,S.Share_Permissions)
    ;
