Cursorfetch：在INTO列表中声明的变量数量必须与选定列的变量数量相匹配

我有以下存储过程，并且如果我们在SQL分析器上执行此操作，它将返回记录没有任何问题。但是，如果我通过ASP.NET执行此操作（我正在使用EntitySpace对象）来将此查询生成到数据表中并且它说：“Cursorfetch：在INTO列表中声明的变量数必须与所选列的变量数相匹配。”Cursorfetch：在INTO列表中声明的变量数量必须与选定列的变量数量相匹配

我已经与EntitySpace团队讨论过这个问题，他们说这是查询问题？！？！任何想法家伙？我们坚持这个问题，任何指导或提示都会很好。

我们使用的环境： .NET 4 EntitySpace 2010 SQL Server 2005数据库

这看起来像是你可能使用`UNPIVOT`的。它仍然需要动态SQL，但我认为代码会更简单。 – 2011-01-23 23:02:05

你的问题是与光标SURVEY_RESULT_CURSOR与列的变量数定义的事实

'DECLARE SURVEY_RESULT_CURSOR CURSOR FOR 
SELECT tid, FirstName, LastName, Email, ' + @ColumnNameRow + '

而FETCH .. INTO子句具有要插入的列的固定列表

FETCH NEXT FROM SURVEY_RESULT_CURSOR 
INTO @tid, @FirstName, @LastName, @Email, 
    @Q010101, @Q010102, @Q010103, @Q010201, @Q010202, @Q010203, @Q010301, @Q010302, @Q010303, @Q010401, @Q010402, @Q010403, 
    @Q010501, @Q010502, @Q010503, @Q010601, @Q010602, @Q010603, @Q010701, @Q010702, @Q010703, @Q010801, @Q010802, @Q010803, 
    @Q010901, @Q010902, @Q010903, @Q011001, @Q011002, @Q011003, @Q011101, @Q011102, @Q011103, @Q011201, @Q011202, @Q011203, 
    @Q011301, @Q011303

当这两个计数不匹配时，您将得到该错误。

想想是否应该是一个静态计数（甚至不需要QuestionCursor）或重新考虑你的做法（也许动态SQL）

编辑：你仍然可以保持读取到变量列表从SURVEY_RESULT_CURSOR固定，两个条件

的变量的列表是等于或大于将产生被填充到全列计数时每次使用
可变@ColumnNameRow的最大列数多。

对于2，不难计数有多少个逗号（假设列名没有逗号），然后根据需要追加尽可能多的cast(NULL as varchar(5)) dummcol1, ..。将varchar（5）转换为varvar（1000）的@var将工作得很好。

要计算逗号：

set @commacount = len(@ColumnNameRow) - len(replace(@ColumnNameRow,',',''))

挑战在于我们正在处理表格，根据数据，潜在的字段名称不同。这就是为什么我们必须这样做。我们知道这将是相同数量的领域。但我想我可以使用通用字段名填充数据，然后将其用于光标后面。无论如何，我会尝试这种方法，并感谢您指出我。 – dcpartners 2011-01-24 00:01:19
