[20210722]sqlplus下show recycebin的小問題.txt
--//sqlplus下執行show recycebin遇到一些疑問,通過測驗慢慢展開問題的探究.
1.環境:
SCOTT@test01p> @ ver1
PORT_STRING VERSION BANNER CON_ID
------------------------------ -------------- -------------------------------------------------------------------------------- ----------
IBMPC/WIN_NT64-9.1.0 12.2.0.1.0 Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production 0
SCOTT@test01p> create table tx as select * from dept ;
Table created.
SCOTT@test01p> create table ty as select * from dept ;
Table created.
2.測驗:
SCOTT@test01p> show recyclebin
SCOTT@test01p> drop table tx ;
Table dropped.
SCOTT@test01p> drop table ty ;
Table dropped.
SCOTT@test01p> show recyclebin
ORIGINAL NAME RECYCLEBIN NAME OBJECT TYPE DROP TIME
---------------- ------------------------------ ------------ -------------------
TX BIN$T7f14az+TMuluJgGIOXiPA==$0 TABLE 2021-07-21:20:33:43
TY BIN$5quvB25qT7eMZtdPExTTZg==$0 TABLE 2021-07-21:20:33:45
--//OK正確.在結尾加入分號看看.
SCOTT@test01p> show recyclebin;
ORIGINAL NAME RECYCLEBIN NAME OBJECT TYPE DROP TIME
---------------- ------------------------------ ------------ -------------------
TX BIN$T7f14az+TMuluJgGIOXiPA==$0 TABLE 2021-07-21:20:33:43
TY BIN$5quvB25qT7eMZtdPExTTZg==$0 TABLE 2021-07-21:20:33:45
--//OK正確.在結尾加入空格(tab鍵)與分號看看.
SCOTT@test01p> show recyclebin ;
--//顯示為空,為什么?
3.使用toad自帶的SQL Tracker跟蹤:
SELECT ORIGINAL_NAME ORIGNAME_PLUS_SHOW_RECYC,
OBJECT_NAME OBJECTNAME_PLUS_SHOW_RECYC,TYPE OBJTYPE_PLUS_SHOW_RECYC,
DROPTIME DROPTIME_PLUS_SHOW_RECYC
FROM USER_RECYCLEBIN
WHERE CAN_UNDROP = 'YES'
AND ORIGINAL_NAME = UPPER(:NMBIND_SHOW_OBJ)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ORDER BY ORIGINAL_NAME,DROPTIME DESC,OBJECT_NAME;
--//為了美觀,我做了格式化處理.你可以發現下劃線帶入引數:NMBIND_SHOW_OBJ.很明顯我在分號前一個空格的情況下,
--//帶入的引數為空,這樣就沒有顯示.
SCOTT@test01p> show recyclebin tx
ORIGINAL NAME RECYCLEBIN NAME OBJECT TYPE DROP TIME
---------------- ------------------------------ ------------ -------------------
TX BIN$T7f14az+TMuluJgGIOXiPA==$0 TABLE 2021-07-21:20:33:43
SCOTT@test01p> show recyclebin tx ;
ORIGINAL NAME RECYCLEBIN NAME OBJECT TYPE DROP TIME
---------------- ------------------------------ ------------ -------------------
TX BIN$T7f14az+TMuluJgGIOXiPA==$0 TABLE 2021-07-21:20:33:43
--//你可以發現帶入引數的情況下顯示正確.如果你執行show recyclebin;執行的sqlplus如下:
SELECT ORIGINAL_NAME ORIGNAME_PLUS_SHOW_RECYC,
OBJECT_NAME OBJECTNAME_PLUS_SHOW_RECYC,TYPE OBJTYPE_PLUS_SHOW_RECYC,
DROPTIME DROPTIME_PLUS_SHOW_RECYC
FROM USER_RECYCLEBIN
WHERE CAN_UNDROP = 'YES'
ORDER BY ORIGINAL_NAME,DROPTIME DESC,OBJECT_NAME
--//沒有系結變數,說明我的判斷正確.
4.繼續,以上測驗在windows下進行,如果linux呢?
