--Oracle 預設分割槽名 SYS_P 開頭

  1. select
  2.   table_name ,
  3.   partition_name ,
  4.   high_value
  5. from user_tab_partitions
  6. where table_name like 'FACT_STORAGE_SHEET_%' --and partition_name like 'SYS%'
  7. order by 1,2;

  9. TABLE_NAME              PARTITION_NAME        HIGH_VALUE
  10. ---------------------  --------------------- ---------------
  11. FACT_STORAGE_SHEET_2    P0                    19900101
  12. FACT_STORAGE_SHEET_2    SYS_P1000             20150602
  13. FACT_STORAGE_SHEET_2    SYS_P1001             20150603
  14. FACT_STORAGE_SHEET_2    SYS_P1002             20150604
  15. FACT_STORAGE_SHEET_2    SYS_P1003             20150605
  16. FACT_STORAGE_SHEET_2    SYS_P1004             20150606


  1. Oracle 自動建立分割槽，分割槽名字預設以 "SYS_P" 開頭，為方便日常查詢，每天中午12點自動重新命名分割槽。
  2. 儲存過程的執行指令碼：/yohodata/fjzcau/scripts/fact_storage_sheet_rename_partition.sh
