Question

我在MS SQL中创建了一个视图。它工作得很好。当我将项目导出并导入Oracle环境时，视图不再起作用。据我所知，我使用了META SQL。

希望有人可以提供帮助！

SELECT OPRID 
 , DESCR1 
 , DESCR 
 , DESCR5 
 , DESCR6 
 , DESCR7 
 , YEAR 
 , WEEKOFYEAR 
 --When working more then 6 hours, subtract .5 hours break
 , CASE WHEN (CONVERT(DECIMAL(10,1) 
 , DATEDIFF(MINUTE 
 , DG_MONDAY_START 
 , DG_MONDAY_END))/60) >= 6 THEN (CONVERT(DECIMAL(10,1) 
 , DATEDIFF(MINUTE 
 , DG_MONDAY_START 
 , DG_MONDAY_END))/60 - 0.5) ELSE (CONVERT(DECIMAL(10,1)

   AND (DG_MONDAY_START != DG_MONDAY_END 
    OR DG_TUESDAY_START != DG_TUESDAY_END 
    OR DG_WEDNESDAY_START != DG_WEDNESDAY_END 
    OR DG_THURSDAY_START != DG_THURSDAY_END 
    OR DG_FRIDAY_START != DG_FRIDAY_END)

Answer 1

在您的查询中，您使用CONVERT命令，但在Oracle中，您必须使用CAST。

必须使用NUMBER类型更改DECIMAL类型，如下所示。

而不是：

CONVERT(DECIMAL(10,1), field)

使用：

CAST(field as NUMBER(10,1))

告诉我它是否正常

编辑评论后

在Oracle中，Sql Server函数DATEDIFF已替换为-符号，作为两个DATA字段之间的正常差异。

我建议你site在哪里可以找到Oracle 10g和Sql Server 2008R2之间的等效功能
