获取sql存储过程表类型中的错误

我有这个过程，我想在表中插入值列表，我想检查重复值并返回它，但我得到了这个错误

错误：

子查询返回了多个值。当子查询在=、！=、=或者当子查询用作表达式时

ALTER PROCEDURE [dbo].[insertData]
    @Value insertTbl READONLY,
    @Result INT OUTPUT
AS
BEGIN
    BEGIN TRY
        IF (SELECT   COUNT(Id)
            FROM     @Values
            WHERE    Id IN (SELECT   Id
                            FROM     [dbo].[username])) = 0
        BEGIN
            INSERT INTO dbo.username ( Id, NAME )
            SELECT   Id,
                     NAME
            FROM     @Values
            WHERE    Id NOT IN (SELECT   Id
                                FROM     [dbo].[username])

            SELECT   @Result = 101
        END
        ELSE
            SELECT   @Result = (
                         SELECT  Id
                         FROM    @Values
                         WHERE   Id IN (SELECT   Id
                                        FROM     [dbo].[username])
                     )
    END TRY

    BEGIN CATCH
        SELECT   ERROR_MESSAGE()
    END CATCH
END

可能是这条线

SELECT @Result=(SELECT Id FROM  @Values  WHERE Id IN (SELECT Id FROM [dbo].[username]))

返回多行。您应该将查询更改为仅返回一个值，如下所示

SELECT @Result=(SELECT top 1 Id FROM  @Values  WHERE Id IN (SELECT Id FROM [dbo].[username]))

或者你应该改变你的逻辑。另一种方法是使用临时表返回ID的列表。请尝试下面的解决方案

-- create temporary table before (!) creating procedure
create table #Resulttab
(
  Result int
)
go
ALTER PROCEDURE [dbo].[insertData]
    @Value insertTbl READONLY,
    @Result INT OUTPUT -- in this solution I think you don't need this parameter
AS
BEGIN
    BEGIN TRY
        IF (SELECT   COUNT(Id)
            FROM     @Values
            WHERE    Id IN (SELECT   Id
                            FROM     [dbo].[username])) = 0
        BEGIN
            INSERT INTO dbo.username ( Id, NAME )
            SELECT   Id,
                     NAME
            FROM     @Values
            WHERE    Id NOT IN (SELECT   Id
                                FROM     [dbo].[username])

            SELECT   @Result = 101
        END
        ELSE
            insert into #Resulttab
            SELECT  Id
            FROM    @Values
            WHERE   Id IN (SELECT   Id
                           FROM     [dbo].[username])            
    END TRY

请试试这个

我已将返回类型更改为VARCHAR。将返回CSV（例如1,3,9…）

另一个选项是返回结果集。对于此替换，请选择@Result=以

插入@Result…
