Sql 从多个表中选择并合并到临时表的单行中
我有三个表（Sql 从多个表中选择并合并到临时表的单行中,sql,sql-server,stored-procedures,temp-tables,Sql,Sql Server,Stored Procedures,Temp Tables,我有三个表（FuelRates\u汽油、FuelRates\u液化石油气和FuelRates\u柴油）使用相同的结构： | OrganisationID | Band1 | Band2 | Band3 | ModifiedDate | |----------------|-------|-------|-------|---------------------| | 1 | 10 | 12 | 19 | 01/05/2016 19:23:
FuelRates\u汽油FuelRates\u液化石油气FuelRates\u柴油| 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 |
组织ID的记录。每个表中将有一条匹配的记录
然后，我需要将结果合并到具有以下结构的临时表中，并返回它：
| 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 |
应将燃油费率
表中的Band1
列插入到燃油费率
临时表的汽油费率
列中。其余列应遵循此约定创建一行，如上所示
SQL并不是我的拿手好戏，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，会出现以下错误：
Msg 213，16级，状态1，程序FuelRates_RetrieveList，第33行
插入错误：提供的值的列名或数目不匹配
表定义
第33行是临时表创建块中的Diesel\U Band1 int
我正在使用SQLServer2005
是什么导致了这个错误？我是否以正确的方式处理了这个问题？我知道它说错误出现在第33行，您将其归因于Diesel_Band1
，但紧接着就是消息：
插入错误：提供的值的列名或数目与表定义不匹配
SQL Server用于定义表的INSERT
方法是首先放置INSERT语句
如果没有按照与定义的表完全相同的顺序插入确切数量的列，则需要定义列和顺序
INSERT INTO myTable (column1, column2, column3,...columnN)
将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]

你可以试试这个

SELECT OrganisationID,

谢谢谢奈斯。我的代码现在看起来是这样的：它生成了3行，而不是我要查找的那一行。我能不能把这些合并成一行？J Greene的回答就是我要说的。唯一需要注意的是，我会确保直接在FROM
后面的表有OrganizationID的记录，否则即使其他表有记录，也不会返回任何内容。谢谢Shaneis。我的代码现在看起来是这样的：它生成了3行，而不是我要查找的那一行。我能不能把这些合并成一行？J Greene的回答就是我要说的。唯一需要注意的是，我会确保直接在FROM
后面的表有OrganizationID的记录，否则即使其他表有记录，也不会返回任何内容。这就是为什么我喜欢这样！谢谢这是一种享受。虽然您在SELECT中有语法错误（p，Band3作为汽油机）\u Band3
-逗号而不是句号），这就是我喜欢的原因！谢谢这是一种享受。尽管您在SELECT中有语法错误（p，第3栏为汽油色\u第3栏
-逗号而不是句号）
