我创建了以下存储过程：

   LOOP
   --FETCH costcenter_WFDB INTO varCost_Center;

在上面的存储过程中，TPI_Deata是在过程中填充的全局临时表。在sql server中我们曾经做过＆＃34; select * from temp_table＆＃34;在存储过程内部查看执行存储过程时的结果但是在这里我应该如何处理全局临时表，这样当我执行存储过程时，我得到表中的记录集？

Answer 1

使用Oracle时，您应该忘记MSSQL。他们的方法完全不同。如果您希望从存储过程返回一些表格数据，通常应使用out REF CURSOR参数。如果您只想调试数据，那么在调用SP后执行SELECT。

坏消息是，在12c中，Oracle实现了MSSQL-like facility来减轻ms开发人员的痛苦。

Answer 2

完成此过程后，您可以查询表格。如果您看到零行，那可能是因为临时表是使用ON COMMIT DELETE ROWS（默认值）而不是ON COMMIT PRESERVE ROWS声明的。

http://docs.oracle.com/cd/E11882_01/server.112/e41084/statements_7002.htm#i2189569

如果您尝试从UI查看结果，则应返回引用游标或使用常规表，以便数据保持不变。在全局临时表中，一旦会话关闭，数据就会消失。

在oracle中从存储过程内部查看临时表
