列名不匹配 table 使用 SELECT 变量作为 INSERT 值

Question

我创建了一个存储过程，它会在必要时 INSERT/UPDATE。我正在使用这种方法来评估是否必须插入：

INSERT INTO X
SELECT @A, @B, @C -- Exactly as the table, all nullables
WHERE NOT EXISTS (SELECT * from ... WHERE condition)

但是我收到了

Msg 213, Level 16, State 1, Procedure ArtigoEAN_Remover, Line 48 [Batch Start Line 7] Column name or number of supplied values does not match table definition.

这是我的完整代码（我标记了 第 48 行）：

@ArtigoID AS varchar(14),
@TipoArtigo AS varchar(3),
@CodBarras AS varchar(24)

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

    IF (@ArtigoID IS NOT NULL AND @TipoArtigo IS NULL) OR (@ArtigoID IS NULL AND @TipoArtigo IS NOT NULL)
    BEGIN
        PRINT 'Tem que escolher ArtigoID & TipoArtigo para remover código EAN da referência.'
        RETURN
    END
    --
    IF (@CodBarras IS NOT NULL) AND (@ArtigoID IS NOT NULL OR @TipoArtigo IS NOT NULL)
    BEGIN
        PRINT 'Escolher Código EAN apenas (Para remover esse código de barras de todas as referências) OU ArtigoID + TipoArtigo (remover todos os códigos EAN associados a essa referência)'
        RETURN
    END
    --
    IF @ArtigoID IS NOT NULL AND @TipoArtigo IS NOT NULL 
    BEGIN 

    UPDATE [s].[dbo].[FArtigo]
    SET CodBarras = ''
    WHERE ArtigoID = @ArtigoID AND TipoArtigo = @TipoArtigo AND CodBarras = @CodBarras
    -- LINE 48
    INSERT INTO [s].[dbo].[Infolog_ArtigoEAN] 
    SELECT @ArtigoID,@TipoArtigo,@CodBarras
    WHERE NOT EXISTS (SELECT * FROM [s].[dbo].[Infolog_ArtigoEAN] WHERE ArtigoID = @ArtigoID AND TipoArtigo = @TipoArtigo AND CodBarras = @CodBarras)
    -- Inserts above if nox exist, update below in any case.
    UPDATE [s].[dbo].[Infolog_ArtigoEAN] SET CodBarras = '' WHERE ArtigoID = @ArtigoID AND TipoArtigo = @TipoArtigo AND CodBarras = @CodBarras

    INSERT INTO [s].[dbo].[ArtigoEAN]
    SELECT @ArtigoID,@TipoArtigo,@CodBarras
    WHERE NOT EXISTS (SELECT * FROM [s].[dbo].[Infolog_ArtigoEAN] WHERE ArtigoID = @ArtigoID AND TipoArtigo = @TipoArtigo AND CodBarras = @CodBarras)
    UPDATE [s].[dbo].[ArtigoEAN] SET CodBarras = '' WHERE ArtigoID = @ArtigoID AND TipoArtigo = @TipoArtigo AND CodBarras = @CodBarras

    END
    --
    IF @CodBarras IS NOT NULL AND (@ArtigoID IS NULL AND @TipoArtigo IS NULL) 
    BEGIN

    UPDATE [s].[dbo].[FArtigo] SET CodBarras = '' WHERE CodBarras = @CodBarras
    UPDATE [s].[dbo].[Infolog_ArtigoEAN] SET CodBarras = '' WHERE CodBarras = @CodBarras
    UPDATE [s].[dbo].[ArtigoEAN] SET CodBarras = '' WHERE CodBarras = @CodBarras

    END
END

所以我的问题是，为什么它在第 48 行之后尝试执行插入，而我只是在更改（保存）程序，我什至运行它没有参数。

请记住，我想使用 SELECT 作为条件进行插入 (INSERT INTO dbo.Example SELECT (to,insert,if,true) WHERE NOT EXISTS (SELECT * 来自 dbo.Example WHERE myCondition = notExist)

您收到此错误是因为 table 中的列数与您在插入语句中指定的值的数量不匹配。

在您的查询中，您提供了 3 个值，因此您的 table 中可能有超过 3 列或少于 3 列。

为避免将来出现此类错误，请不要指定

INSERT INTO TableName
VALUES(1,2,3)

指定您要插入值的列名称。像这样

INSERT INTO TableName(Col1,Col2,Col3)
VALUES(1,2,3)

或

INSERT INTO X(Col1,Col2,Col3)
SELECT @A, @B, @C

您不需要运行脚本/程序来获取错误，SQL 服务器将 return 编译时的错误，即；当您尝试创建或更改程序时

列名不匹配 table 使用 SELECT 变量作为 INSERT 值

Column names don't match table using SELECT variables as INSERT values

tsql

sql-server

select

if-statement

where-clause
