Sql 无法将用户定义的记录插入表中

场景

我已经创建了一个存储过程，其中我将用户定义的表作为参数，然后首先检查

角色ID

和

表单ID

是否存在，然后更新现有表。否则，我将插入到现有表中

问题

在我的存储过程中写入insert查询后，我在更改存储过程时遇到以下错误

Msg 137，16级，状态1，程序SP\u设置\u角色\u权限\u保存\u和更新，第17行 必须声明标量变量“@Temp”。 Msg 137，16级，状态1，程序SP\u设置\u角色\u权限\u保存\u和更新，第17行 必须声明标量变量“@Temp”

下面是我的SP代码：

CREATE TYPE _ROLERIGHTSSCHEMA as Table (
    _Role_ID int,
    _Form_ID int,
    _Form_Name varchar(100),
    _Can_View bit,
    _Can_Edit bit,
    _Can_Prepare_By bit,
    _Can_Change_Status_By bit,
    _Prepared_By_ID int,
    _Prepared_Date datetime
)

ALTER PROCEDURE SP_SETUP_ROLES_RIGHTS_SAVE_AND_UPDATE
(@Temp _ROLERIGHTSSCHEMA ReadOnly)
AS
BEGIN
    IF EXISTS(SELECT * FROM ROLE_RIGHTS WHERE Role_ID = @Temp.Role_ID AND Form_ID = @Temp.Form_ID)
    BEGIN
        Update Role_Rights
        set Can_View = t._Can_View,
            Can_Edit = t._Can_Edit,
            Can_Prepare_By = t._Can_Prepare_By,
            Can_Change_Status_By = _Can_Change_Status_By,
            Modified_By_ID = 0,
            Modified_Date = GETDATE()
            From @Temp t
            WHERE Role_Rights.Role_ID = t._Role_ID and Role_Rights.Form_ID = t._Form_ID
        END
    ELSE
    BEGIN
        INSERT INTO Role_Rights (
            Role_ID,
            Form_ID,
            Can_View,
            Can_Edit,
            Can_Prepare_By,
            Can_Change_Status_By,
            Prepared_By_ID,
            Prepared_Date
        ) SELECT _Role_ID, _Form_ID, _Can_View, _Can_Edit, _Can_Prepare_By, _Can_Change_Status_By, 0, GETDATE() FROM @Temp
    END
END

要一次更新/插入多条记录，请使用：

编辑：

CREATE TYPE _ROLERIGHTSSCHEMA as Table (
    _Role_ID int,
    _Form_ID int,
    _Form_Name varchar(100),
    _Can_View bit,
    _Can_Edit bit,
    _Can_Prepare_By bit,
    _Can_Change_Status_By bit,
    _Prepared_By_ID int,
    _Prepared_Date datetime
)

ALTER PROCEDURE SP_SETUP_ROLES_RIGHTS_SAVE_AND_UPDATE
(@Temp _ROLERIGHTSSCHEMA ReadOnly)
AS
BEGIN
    IF EXISTS(SELECT * FROM ROLE_RIGHTS WHERE Role_ID = @Temp.Role_ID AND Form_ID = @Temp.Form_ID)
    BEGIN
        Update Role_Rights
        set Can_View = t._Can_View,
            Can_Edit = t._Can_Edit,
            Can_Prepare_By = t._Can_Prepare_By,
            Can_Change_Status_By = _Can_Change_Status_By,
            Modified_By_ID = 0,
            Modified_Date = GETDATE()
            From @Temp t
            WHERE Role_Rights.Role_ID = t._Role_ID and Role_Rights.Form_ID = t._Form_ID
        END
    ELSE
    BEGIN
        INSERT INTO Role_Rights (
            Role_ID,
            Form_ID,
            Can_View,
            Can_Edit,
            Can_Prepare_By,
            Can_Change_Status_By,
            Prepared_By_ID,
            Prepared_Date
        ) SELECT _Role_ID, _Form_ID, _Can_View, _Can_Edit, _Can_Prepare_By, _Can_Change_Status_By, 0, GETDATE() FROM @Temp
    END
END

超过

如果存在/更新/插入基于集的

：

Single insert   -- no difference
Single update   -- no difference
Multiple insert -- no difference
Multiple update -- no difference
Multiple insert/update:  MERGE     -- will handle it correctly 
                         IF EXISTS -- you will lose records to insert

---

更新/插入不带IF部件：

Update Role_Rights
        set Can_View = t._Can_View,
            Can_Edit = t._Can_Edit,
            Can_Prepare_By = t._Can_Prepare_By,
            Can_Change_Status_By = _Can_Change_Status_By,
            Modified_By_ID = 0,
            Modified_Date = GETDATE()
            From @Temp t
WHERE Role_Rights.Role_ID = t._Role_ID and Role_Rights.Form_ID = t._Form_ID;

INSERT INTO Role_Rights (
        Role_ID,
        Form_ID,
        Can_View,
        Can_Edit,
        Can_Prepare_By,
        Can_Change_Status_By,
        Prepared_By_ID,
        Prepared_Date
    ) 
 SELECT _Role_ID, _Form_ID, _Can_View, _Can_Edit,
        _Can_Prepare_By, _Can_Change_Status_By, 0, GETDATE() 
 FROM @Temp t
 WHERE NOT EXISTS (SELECT 1
                   FROM Role_Rights rr
                   WHERE rr.Role_ID = t._Role_ID 
                     and rr.Form_ID = t._Form_ID);

---

exists子句中的语句格式不正确-这会引发错误。你有：

IF EXISTS(SELECT * FROM ROLE_RIGHTS WHERE Role_ID = @Temp.Role_ID AND Form_ID = @Temp.Form_ID)

但它应该是：

if exists (select * from ROLE_RIGHTS as rr inner join @Temp as tp on rr.Role_ID = tp._Role_ID and rr.Form_ID = tp._Form_ID)

---

正如@lad2025已经提到的那样，这种修正是毫无意义的

在ELSE之后的语句中尝试使用多个IF子句，检查这是否有效

CREATE TYPE _ROLERIGHTSSCHEMA as Table (
        _Role_ID int,
        _Form_ID int,
        _Form_Name varchar(100),
        _Can_View bit,
        _Can_Edit bit,
        _Can_Prepare_By bit,
        _Can_Change_Status_By bit,
        _Prepared_By_ID int,
        _Prepared_Date datetime
    )


    ALTER PROCEDURE SP_SETUP_ROLES_RIGHTS_SAVE_AND_UPDATE
    (@Temp _ROLERIGHTSSCHEMA ReadOnly)
    AS
    BEGIN
        IF EXISTS(SELECT * FROM ROLE_RIGHTS WHERE Role_ID = @Temp.Role_ID AND Form_ID = @Temp.Form_ID)
        BEGIN
            Update Role_Rights
            set Can_View = t._Can_View,
                Can_Edit = t._Can_Edit,
                Can_Prepare_By = t._Can_Prepare_By,
                Can_Change_Status_By = _Can_Change_Status_By,
                Modified_By_ID = 0,
                Modified_Date = GETDATE()
                From @Temp t
                WHERE Role_Rights.Role_ID = t._Role_ID and Role_Rights.Form_ID = t._Form_ID
            END
        ELSE
        BEGIN
        IF NOT EXISTS(SELECT * FROM ROLE_RIGHTS WHERE Role_ID = @Temp.Role_ID AND Form_ID = @Temp.Form_ID)
        BEGIN 
            INSERT INTO Role_Rights (
                Role_ID,
                Form_ID,
                Can_View,
                Can_Edit,
                Can_Prepare_By,
                Can_Change_Status_By,
                Prepared_By_ID,
                Prepared_Date
            ) SELECT _Role_ID, _Form_ID, _Can_View, _Can_Edit, _Can_Prepare_By, _Can_Change_Status_By, 0, GETDATE() FROM @Temp
        END
        END 
    END

你应该考虑不要使用SPY前缀。它可能会导致性能问题和其他一些有趣的挑战。选择不同的前缀，或者甚至更好，完全不选择前缀。之前，我写了上面的if条件更新查询工作正常。我更新了一条记录，但在写入

IF

条件后，我的插入代码不起作用。@Ahmeralahsan使用IF/update/insert对多条记录不起作用。首先，我检查了你的答案，结果很好。但是在@smor-answer之后，我只是编辑了我的

IF

条件，它的效果非常好。你的答案和@smor-answer之间的主要区别是什么，因为我发现这两个答案都很有用，但我不清楚我选择了哪一个作为我的代码。使用这种方法有很大的缺点（当@Temp table有两条记录要更新/插入时——根本就没有插入部分）。当然，OP可以使用游标并分别处理每一行，但这比基于集合的方法慢得多。
