我正在使用SQL Server Management Studio来构建报告问题的查询。
单独使用这些查询可以正常工作，但是一旦通过使用联合添加它们，我就会收到以下错误消息：
第245层状态1的状态1行
将varchar值'OFC'转换为数据类型smallint时转换失败
我尝试在Cast和Convert列上使用w.wpage和p.ppage。我尝试将它们直接用于两个子查询的case语句，这些子查询的结果各不相同，但始终是：
转换时转换失败...
错误。
任何帮助或建议，将不胜感激。

答案 0 :(得分：1)
由于您的问题开始于添加联合运算符，因此看来您列中的数据类型不匹配。字符串“ OFC”不能转换为整数，因此将始终失败。在查看列的说明时，我很可能会猜测PackNum是整数，Article是字符串。
要查找有问题的列，可以做的是在FROM部分之前使用“ INTO #temp”语句独立运行查询。然后检查您创建的两个临时表的数据类型。我敢打赌，您会在一个中找到一个int，在另一个中找到一个字符串。
然后根据您的要求扩展查询或将整数列转换为varchar。
