Select 来自多个 table 并组合成单行临时 table

Question

我有三个使用相同结构的 table（FuelRates_Petrol、FuelRates_LPG 和 FuelRates_Diesel）：

| OrganisationID | Band1 | Band2 | Band3 | ModifiedDate        |
|----------------|-------|-------|-------|---------------------|
| 1              | 10    | 12    | 19    | 01/05/2016 19:23:21 |
| 2              | 11    | 12    | 20    | 02/05/2016 19:23:21 |

我需要创建一个存储过程，它将 select 每个 table 的记录与匹配的 OrganisationID。每个table.

中会有一条匹配记录

然后我需要将结果组合成具有以下结构的临时 table 和 return 它：

| OrganisationID | Petrol_Band1 | Petrol_Band2 | Petrol_Band3 | LPG_Band1 | LPG_Band2 | LPG_Band3 | Diesel_Band1 | Diesel_Band2 | Diesel_Band3 | ModifiedDate        |
|----------------|--------------|--------------|--------------|-----------|-----------|-----------|--------------|--------------|--------------|---------------------|
| 1              | 10           | 12           | 19           | 10        | 12        | 19        | 10           | 12           | 19           | 01/05/2016 19:23:21 |

FuelRates_Petrol table 中的 Band1 列应插入到 FuelRates 临时 table 的 Petrol_Band1 列中。其余列应遵循此约定以创建单行，如上所示。

SQL 不是我的包，但这是我的努力：

ALTER PROCEDURE [dbo].[FuelRates_RetrieveList] 
    @OrganisationID int
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    CREATE TABLE #FuelRates(
    OrganisationID int,
    Petrol_Band1 int, 
    Petrol_Band2 int,
    Petrol_Band3 int,
    LPG_Band1 int,
    LPG_Band2 int,
    LPG_Band3 int,
    Diesel_Band1 int,
    Diesel_Band2 int,
    Diesel_Band3 int,
    ModifiedDate DateTime)

    SELECT Band1 As Petrol_Band1, Band2 As Petrol_Band2, Band3 As Petrol_Band3, ModifiedDate, OrganisationID FROM [FuelRates_Petrol]
    WHERE OrganisationID = @OrganisationID
    INSERT INTO #FuelRates

    SELECT Band1 As LPG_Band1, Band2 As LPG_Band2, Band3 As LPG_Band3 FROM [FuelRates_LPG]
    WHERE OrganisationID = @OrganisationID
    INSERT INTO #FuelRates

    SELECT Band1 As Diesel_Band1, Band2 As Diesel_Band2, Band3 As Diesel_Band3 FROM [FuelRates_Diesel]
    WHERE OrganisationID = @OrganisationID
    INSERT INTO #FuelRates

    SELECT * FROM #FuelRates

    DROP TABLE #FuelRates
END

执行此操作时出现以下错误：

Msg 213, Level 16, State 1, Procedure FuelRates_RetrieveList, Line 33 Insert Error: Column name or number of supplied values does not match table definition.

第 33 行 Diesel_Band1 int, 在临时 table 创建块中。

我正在使用 SQL Server 2005。

是什么导致了这个错误，我是否以正确的方式解决了这个问题？

Answer 1

我知道它说错误在第 33 行，您已将其归因于 Diesel_Band1 但紧随其后的是消息：

Insert Error: Column name or number of supplied values does not match table definition.

SQL Server for defined tables 的INSERT 方法是先放置插入语句。

如果您没有按照定义的顺序插入准确的列数 table，那么您需要定义列和顺序。

INSERT INTO myTable (column1, column2, column3,...columnN)

将您的插入内容更改为以下内容：

INSERT INTO #FuelRates
    (Petrol_Band1, Petrol_Band2, Petrol_Band3, ModifiedDate, OrganisationID)
    SELECT Band1 As Petrol_Band1, Band2 As Petrol_Band2, Band3 As Petrol_Band3, ModifiedDate, OrganisationID 
    FROM [FuelRates_Petrol]
    WHERE OrganisationID = @OrganisationID

Answer 2

你可以试试这个...

ALTER PROCEDURE [dbo].[FuelRates_RetrieveList] 
    @OrganisationID int
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    CREATE TABLE #FuelRates(
    OrganisationID int,
    Petrol_Band1 int, 
    Petrol_Band2 int,
    Petrol_Band3 int,
    LPG_Band1 int,
    LPG_Band2 int,
    LPG_Band3 int,
    Diesel_Band1 int,
    Diesel_Band2 int,
    Diesel_Band3 int,
    ModifiedDate DateTime)

    INSERT INTO #FuelRates
    (OrganisationID, Petrol_Band1, Petrol_Band2, Petrol_Band3,LPG_Band1,LPG_Band2,LPG_Band3,
      Diesel_Band1, Diesel_Band2, Diesel_Band3, ModifiedDate)
    SELECT OrganisationID,
        p.Band1 As Petrol_Band1, p.Band2 As Petrol_Band2, p,Band3 As Petrol_Band3, 
        lp.Band1 As LPG_Band1, lp.Band2 As LPG_Band2, lp.Band3 As LPG_Band3,
        d.Band1 As Diesel_Band1, d.Band2 As Diesel_Band2, d.Band3 As Diesel_Band3,
        GetDate() as ModifiedDate
    FROM [FuelRates_Petrol] p
    LEFT JOIN FuelRates_LPG lp on lp.OrganisationID = p.OrganisationID
    LEFT JOIN FuelRates_Diesel d on d.OrganizationID = p.OrganisationID
    WHERE p.OrganisationID = @OrganisationID

    SELECT * FROM #FuelRates

    DROP TABLE #FuelRates
END
