Question

每当我尝试在数据库的旧副本上运行它时，它就会完美运行。

DECLARE @CompanyName AS VARCHAR(50) 
DECLARE @SQLCommand AS VARCHAR(MAX) = '' 
DECLARE companycursor CURSOR FOR SELECT      
                                    REPLACE([Name],'.','_') as[Name]  
                         FROM        
                                    Company; 

OPEN companycursor 

FETCH companycursor INTO @CompanyName 

WHILE @@FETCH_STATUS = 0 

BEGIN 

    IF @SQLCommand <> '' SET @SQLCommand += 'UNION ALL' 

    SET @SQLCommand += 
    '
    SELECT [Company Name] = ''' + @CompanyName + ''', *
    FROM [' + @CompanyName + '$Sales Line]
    INNER JOIN [' + @CompanyName + '$Sales Header]
    ON [' + @CompanyName + '$Sales Line].[Document No_] = [' + @CompanyName + '$Sales Header].[No_]
    WHERE (YEAR([' + @CompanyName + '$Sales Header].[Posting Date])> CAST(2016 AS int)-1 
    OR YEAR([' + @CompanyName + '$Sales Header].[Posting Date])= CAST(2016 AS int)-1 AND MONTH([' + @CompanyName + '$Sales Header].[Posting Date])> 12-CAST(3 AS int)
    OR YEAR([' + @CompanyName + '$Sales Header].[Posting Date])= CAST(1753 AS int) AND YEAR([' + @CompanyName + '$Sales Header].[Order Date])> CAST(2016 AS int)-1
    OR YEAR([' + @CompanyName + '$Sales Header].[Posting Date])= CAST(1753 AS int) AND YEAR([' + @CompanyName + '$Sales Header].[Order Date])= CAST(2016 AS int)-1 AND MONTH([' + @CompanyName + '$Sales Header].[Order Date])> 12-CAST(3 AS int)) 
    AND YEAR([' + @CompanyName + '$Sales Header].[Posting Date]) < CAST(2017 AS int)+1
'

    FETCH companycursor INTO @CompanyName 
END; 

EXEC(@SQLCommand)

--PRINT @SQLCommand 

CLOSE companycursor 

DEALLOCATE companycursor

但是，当我尝试在实时数据库上运行它时会出错。

Msg 8114，Level 16，State 5，Server VES-SQL01，Line 2 将数据类型nvarchar转换为数字时出错。

Answer 1

通过用SELECT替换EXEC，然后在查询窗口中复制/粘贴输出并执行，这些调试非常好。您可以多次双击红色SQL Server错误，光标将直接跳到问题。

不是解决方案，而是我认为非常雄辩地找到解决方案的方法。
