Question

我得到了，“ Msg 102，Level 15，State 1，Procedure duckbilledPlatypi，Line 21'SUM'附近的语法不正确。”当我尝试在此处执行它时使用此MS SQL Server存储过程Visual Studio（在服务器资源管理器中创建后）：

CREATE PROCEDURE [dbo].[duckbilledPlatypi]
    @Unit varchar(25),
    @BegDate datetime,
    @EndDate datetime
AS

DECLARE 
@Week1End datetime,
@Week2begin datetime

    Select  Description,
    @BegDate  BegDate,
    @Week1End Week1End,
    @Week1End Week2Begin,
    @EndDate EndDate,
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Usage ELSE 0 END) Week1Usage,
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @Week2Begin AND @EndDate THEN Ind.Usage ELSE 0 END) Week2Usage,
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Price ELSE 0 END) Week1Price,
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @Week2Begin AND @EndDate THEN Ind.Price ELSE 0 END) -
   SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Usage ELSE 0 END) UsageVariance
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @Week2Begin AND @EndDate THEN Ind.Usage ELSE 0 END)  -
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Price ELSE 0 END) PriceVariance,
    (SUM(CASE WHEN Ind.InvoiceDate BETWEEN @Week2Begin AND @EndDate THEN Ind.Usage ELSE 0 END)  -
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Price ELSE 0 END) )
    / SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Price ELSE 0 END) PercentageOfPriceVariance
    From    InvoiceDetail Ind
    Where   Ind.Unit = @Unit
    AND @Ind.InvoiceDate BETWEEN @BegDate AND @EndDate

问题在于：

SUM(CASE WHEN Ind.InvoiceDate BETWEEN @Week2Begin AND @EndDate THEN Ind.Usage ELSE 0 END)  -

在上下文中，整个陈述部分是：

SUM(CASE WHEN Ind.InvoiceDate BETWEEN @Week2Begin AND @EndDate THEN Ind.Usage ELSE 0 END)  -
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Price ELSE 0 END) PriceVariance,

我想也许我需要把声明包含在另一对parens中，如下：

*(SUM(CASE WHEN Ind.InvoiceDate BETWEEN @Week2Begin AND @EndDate THEN Ind.Usage ELSE 0 END)  - 
 SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Price ELSE 0 END)) PriceVariance,*

...但我仍然得到与之相同的错误信息。

有了这个（HoneyBadger的回答）：

CREATE PROCEDURE [dbo].[variancePriceByProductWithPriceChangePercentage]
    @Unit varchar(25),
    @BegDate datetime,
    @EndDate datetime
AS

DECLARE 
@Week1End datetime,
@Week2begin datetime

    Select  Description,
    @BegDate  BegDate,
    @Week1End Week1End,
    @Week1End Week2Begin,
    @EndDate EndDate,
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Usage ELSE 0 END) 
Week1Usage,
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @Week2Begin AND @EndDate THEN Ind.Usage ELSE 0 END) 
Week2Usage,
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Price ELSE 0 END) 
Week1Price,
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @Week2Begin AND @EndDate THEN Ind.Price ELSE 0 END) -
   SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Usage ELSE 0 END) 
UsageVariance,
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @Week2Begin AND @EndDate THEN Ind.Usage ELSE 0 END)  -
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Price ELSE 0 END) 
PriceVariance,
    (SUM(CASE WHEN Ind.InvoiceDate BETWEEN @Week2Begin AND @EndDate THEN Ind.Usage ELSE 0 END)  -
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Price ELSE 0 END) )
    / SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Price ELSE 0 END) 
PercentageOfPriceVariance
    From    InvoiceDetail Ind
    Where   Ind.Unit = @Unit
    AND Ind.InvoiceDate BETWEEN @BegDate AND @EndDate
    Group By Description,
    @BegDate,
    @Week1End,
    @Week1End,
    @EndDate

我得到以下手指：

Msg 164，Level 15，State 1，Procedure variancePriceByProductWithPriceChangePercentage，Line 30 每个GROUP BY表达式必须至少包含一个不是外部引用的列。消息207，级别16，状态1，过程variancePriceByProductWithPriceChangePercentage，第16行列名称“用法”无效。消息207，级别16，状态1，过程variancePriceByProductWithPriceChangePercentage，第17行列名称“用法”无效。 Msg 207，Level 16，State 1，Procedure variancePriceByProductWithPriceChangePercentage，Line 20 列名称“用法”无效。 Msg 207，Level 16，State 1，Procedure variancePriceByProductWithPriceChangePercentage，Line 21 列名称“用法”无效。消息207，级别16，状态1，过程variancePriceByProductWithPriceChangePercentage，第23行列名称“使用”无效。

Answer 1

错字：

(function () {
var app = angular.module('segnalazioni', ['filters', 'smart-table', 'smart-table-server']);

app.controller('nuovaSegnalazioneCtrl', [ '$scope', 'DB', function($scope, service) {
    var self = this;
    this.activatedTab = "tab_animale";
    this.chipNumber = null;
    this.indirizzo = 'ind';


    this.setIndirizzo = function() {
        self.indirizzo = "VIA ROMA";
        console.log("AGGIORNAMENTO INDIRIZZO");

    }

这就是为什么你在下一行的SUM(CASE [..snip...][ END) UsageVariance ^--missing comma上得到语法错误的原因。你基本上SUM是无效的。

Answer 2

就像我在评论中所说，你应该添加一个group by。其他人指出你的逗号丢失，我也补充说：

    Select  Description,
    @BegDate  BegDate,
    @Week1End Week1End,
    @Week1End Week2Begin,
    @EndDate EndDate,
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Usage ELSE 0 END) Week1Usage,
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @Week2Begin AND @EndDate THEN Ind.Usage ELSE 0 END) Week2Usage,
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Price ELSE 0 END) Week1Price,
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @Week2Begin AND @EndDate THEN Ind.Price ELSE 0 END) -
   SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Usage ELSE 0 END) UsageVariance,
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @Week2Begin AND @EndDate THEN Ind.Usage ELSE 0 END)  -
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Price ELSE 0 END) PriceVariance,
    (SUM(CASE WHEN Ind.InvoiceDate BETWEEN @Week2Begin AND @EndDate THEN Ind.Usage ELSE 0 END)  -
    SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Price ELSE 0 END) )
    / SUM(CASE WHEN Ind.InvoiceDate BETWEEN @BegDate AND @Week1End THEN Ind.Price ELSE 0 END) PercentageOfPriceVariance
    From    InvoiceDetail Ind
    Where   Ind.Unit = @Unit
    AND Ind.InvoiceDate BETWEEN @BegDate AND @EndDate
    Group By Description

编辑：group by中的变量显然是错误的

此SP中'SUM''附近的'语法不正确'在哪里？
