列名不正确createDate [英] Incorrect column name createDate

问题描述

我有以下存储过程。当我运行它并插入我的参数时，它会提示我错误作为上面的标题。以下是我的代码：

Hi, i have the following stored procedure. When i run it and i insert my parameters, it would prompt me the error as title above. Below are my codes:

DECLARE @SQL NVARCHAR(MAX)
DECLARE @params NVARCHAR(MAX)

SELECT @SQL = 'SELECT CustomerName,[0] as Pending, [1] as Save_As_Draft, [2] as Spec_Confirmed, [3] as Request_Revision, [4] as Withdraw, [5] as Pending_RND, [6] as Pending_QC, [7] as Manday_Confirmed, [0]+[1]+[2]+[3]+[4]+[5]+[6]+[7] as Total
FROM
(
    SELECT P.DocStatus,C.CustomerName,P.CustomerID, YEAR(CreateDate) as createYear
    FROM dbo.CRF_Project P
    INNER JOIN dbo.CustomerList C
    ON P.CustomerID = C.CustomerID
) p

PIVOT
(
    COUNT (createYear) FOR DocStatus IN ([0], [1], [2], [3], [4], [5], [6], [7])

) AS pvt '

SELECT @params = '@CUSTNAME VARCHAR(MAX),
                  @YEAR VARCHAR(MAX)'

IF(@CUSTNAME != '' AND @YEAR = '')
    SELECT @SQL = @SQL + ' WHERE CustomerName IN (' + @CUSTNAME + ')'
ELSE IF(@CUSTNAME = '' AND @YEAR != '')
    SELECT @SQL = @SQL + ' WHERE createYear = ' + @YEAR +''
ELSE IF(@CUSTNAME != '' AND @YEAR != '')
    SELECT @SQL = @SQL + ' WHERE CustomerName IN (' + @CUSTNAME + ') AND createYear = ' + @YEAR +''
ELSE
    SELECT @SQL = @SQL

EXEC sp_executesql @SQL, @params, @CUSTNAME, @YEAR
END

我的输入是@CUSTNAME'Osm'和@YEAR'2014'

my input are @CUSTNAME 'Osm' and @YEAR '2014'

推荐答案

< b>的确，它属于dbo.CRF_Project

告诉SQL：

"indeed, it is belongs to dbo.CRF_Project"
So tell SQL that:

SELECT P.DocStatus,C.CustomerName,P.CustomerID, YEAR(P.CreateDate) as createYear

您不能将现有字段名称用作别名：

You can't use an existing field name as an alias:

SELECT P.DocStatus,C.CustomerName,P.CustomerID, YEAR(CreateDate) as createYear

需要

needs to be

SELECT P.DocStatus,C.CustomerName,P.CustomerID, YEAR(CreateDate) as Create_Year 

或类似的东西。此外，看起来您使用的是不区分大小写的SQL版本（这不是批评，只是信息:)）

or something similar. Also, it looks like you are using a case-insensitive version of SQL (that isn't a criticism, just information :) )
