刪除表空間時，遇到了ORA-14404錯誤

 

Oracle中刪除表空間時，遇到了ORA-14404錯誤。

 

錯誤信息以下：

SQL> DROP TABLESPACE PART1 INCLUDING CONTENTS AND DATAFILES;
DROP TABLESPACE PART1 INCLUDING CONTENTS AND DATAFILES
ORA-14404: partitioned table contains partitions in a different tablespace

 

一樣查看官方文檔的說明：

Oracle Error: ORA-14404 Error Description: Partitioned table contains partitions in a different tablespace Error Cause: An attempt was made to drop a tablespace which contains tables whose partitions are not completely contained in this tablespace. Action: Find tables with partitions which span the tablespace being dropped and some other tablespace(s). Drop these tables or move partitions to a different tablespace.

 

問題分析：

ORA-14404錯誤說明有某個表不單單隻在當前表空間，在其餘表空間也存有數據。解決方法，Oracle的建議也比較清晰，要麼刪除這個表，要麼把移動partitions到一個單獨的表空間中。對於我來講，我刪除此表便可。

 

首先須要找到究竟是哪張表跨越了不一樣表空間：

SQL> SELECT x.table_name,x.partition_name,x.tablespace_name 表空間1, y.tablespace_name 表空間2
  2  FROM dba_tab_partitions x, dba_tab_partitions y
  3  WHERE x.tablespace_name ='PART1' AND y.tablespace_name <> 'PART1' AND x.table_name=y.table_name;
TABLE_NAME                     PARTITION_NAME                 表空間1                        表空間2
------------------------------ ------------------------------ ------------------------------ ------------------------------
RANGE_PART                     YR0                            PART1                          PART2
RANGE_PART                     YR0                            PART1                          PART3
RANGE_PART                     YR0                            PART1                          PART4

即找到名稱爲RANGE_PART的分區表的數據在表空間PART1、PART2和PART3上，接下來刪除此表便可。

SQL> drop table RANGE_PART;Table dropped
