存储过程中的排序规则冲突

如何解决存储过程中的排序规则冲突

在SQL查询中应用并集时，可能会要求并集查询中的每个字段必须具有相同的详细信息。例如字段数，各个字段的数据类型。

您的错误表示价值排序规则有所不同。您必须对两个查询中的列进行相同的排序规则。

下面的脚本更改可以解决您的问题。

IF @counter = @HeaderCount
  BEGIN
    SET @sql = @sql + ''''+@Qualifier+'''+ cast(min(case ordinal_position when '+cast(@counter as varchar)+' then column_name Collate latin1_General_CI_AI end) as varchar)   +'''+@Qualifier+''' as ['+@colname+'] '
  END
ELSE
  BEGIN
    SET @sql = @sql + ''''+@Qualifier+'''+cast(min(case ordinal_position  when '+cast(@counter as varchar)+' then column_name Collate latin1_General_CI_AI end) as varchar)  +'''+@Qualifier+''' as ['+@colname+'], '
  END

解决方法

我的存储过程在执行时抛出错误：

错误：无法创建分隔的文本文件（原因：无法进行从varchar值到varchar的隐式转换，因为在UNION ALL运算符中，由于“
Latin1_General_CI_AI”和“
Latin1_General_100_CI_AS_KS_SC”之间的排序规则冲突，导致无法解析该值的排序规则。）

我的存储过程基本上会创建一个带分隔符的文件，并将表或视图与文件名一起作为输入。

我知道这是排序规则问题，但是我尝试在查询中放置Collate Database_Default和Collate Catalog_Default，但是该错误无法解决。

有人能指导我做错什么吗？
