1查询所有@  替换成:

2 SqlDatabase-->OracleDatabase

3 top

4 STUFF--->wm_concat

5 dbo.  去除

6 as 去除

7 case when

8 with  xxx as

9 cast

10 isnull---》nvl

11 GETDATE()  ---》  sysdate

12 NEWID()-----SYS_GUID()

13 null和’’(空字符串)是一个意思     https://www.cnblogs.com/memory4young/p/use-null-empty-space-in-oracle.html

14 oracle 没有 [字段]  这种表达方式 去掉 中括号
