Sql插入错误 - “子查询返回超过1个值”

在下面的代码中，我将多个值用逗号分隔到@i_CustomerGroupID和一个值到@ i_LocationID。其中我面临的问题是“子查询返回的值超过1 。当子查询遵循=，！=，<，< =，>，> =或当子查询用作表达式时，这是不允许的。声明已被终止。“。请帮我解决问题。Sql插入错误 - “子查询返回超过1个值”

ALTER PROCEDURE [dbo].[spInsertCustomerGroupLocationMap] 
    -- Add the parameters for the stored procedure here 
    @i_LocationID int, 
    @i_CustomerGroupID varchar(100) 

    --WITH ENCRYPTION 
AS 
BEGIN 
    -- SET NOCOUNT ON added to prevent extra result sets from 
    -- interfering with SELECT statements. 
    SET NOCOUNT ON; 

    -- Insert statements for procedure here 
    IF NOT EXISTS (SELECT 1 FROM CustomerGroupLocationMap WHERE LocationID = @i_LocationID AND CustomerGroupID = @i_CustomerGroupID) 
    BEGIN 

     INSERT INTO CustomerGroupLocationMap (LocationID, CustomerGroupID) VALUES (@i_LocationID, (SELECT * FROM dbo.CSVToTable(@i_CustomerGroupID))); 

    END 
END

你想用insert . . . select：

INSERT INTO CustomerGroupLocationMap(LocationID, CustomerGroupID) 
     SELECT @i_LocationID, t.* 
     FROM dbo.CSVToTable(@i_CustomerGroupID) t;

你的函数返回dbo.CSVToTable()比一个值（我假设只有一个列）。正确的语法是insert . . . select。

作为一个说明，insert . . . values真的不需要。即使只有常数，也可以使用insert . . . select。

IF NOT EXISTS (SELECT TOP 1 FROM CustomerGroupLocationMap WHERE LocationID = @i_LocationID AND CustomerGroupID = @i_CustomerGroupID) 
BEGIN 

    INSERT INTO CustomerGroupLocationMap (LocationID, CustomerGroupID) VALUES (@i_LocationID, (SELECT * FROM dbo.CSVToTable(@i_CustomerGroupID))); 

END

你需要重写你的都存在查询和查询 - 插入

IF NOT EXISTS (SELECT 1 FROM CustomerGroupLocationMap WHERE LocationID = @i_LocationID AND CustomerGroupID IN (SELECT * 
    FROM dbo.CSVToTable(@i_CustomerGroupID))) 
BEGIN 

    INSERT INTO CustomerGroupLocationMap (LocationID, CustomerGroupID) 
    SELECT @i_LocationID, i.* FROM dbo.CSVToTable(@i_CustomerGroupID) i; 

END
