Oracle 数据泵备份 带过滤条件的 数据表

需求： 备份一张表恢复至测试环境，但是得有过滤条件

思路：数据泵轻量级备份，query参数

expdp system@LEO directory=DATA_PUMP_DIR dumpfile=DJI_BLACKLIST_DETAIL.dmp logfile=DJI_BLACKLIST_DETAIL.log  tables=LEO.DJI_BLACKLIST_DETAIL query='LEO.DJI_BLACKLIST_DETAIL:" where upper(country_code) = 'CHINA' and trim(dji_name) is not null and trim(dji_id_no) is not null"' 

 Processing object type TABLE_EXPORT/TABLE/STATISTICS/TABLE_STATISTICS
ORA-31693: Table data object "LEO"."DJI_BLACKLIST_DETAIL" failed to load/unload and is being skipped due to error:
ORA-00904: "CHINA": invalid identifier
Master table "SYSTEM"."SYS_EXPORT_TABLE_01" successfully loaded/unloaded

很明显，不太对劲，china 这个条件匹配不到，进行

' CHINA'
"CHINA "
"' CHINA'"
'"CHINA "'

 都试了一遍，不好使。

决定用 parifle 来解决这种问题

vi leo.par

query='LEO.DJI_BLACKLIST_DETAIL:" where upper(country_code) = 'CHINA' and trim(dji_name) is not null and trim(dji_id_no) is not null"'

expdp system@LEO directory=DATA_PUMP_DIR dumpfile=DJI_BLACKLIST_DETAIL.dmp logfile=DJI_BLACKLIST_DETAIL.log  tables=LEO.DJI_BLACKLIST_DETAIL parfile=leo.par

 LRM-00111: no closing quote for value 'null"'
'
LRM-00113: error when processing file 'leo.par'

淦！！！

解决：

去掉了leo.par中的表的单引号。

前：

query='LEO.DJI_BLACKLIST_DETAIL:" where upper(country_code) = 'CHINA' and trim(dji_name) is not null and trim(dji_id_no) is not null"'

后：

query=LEO.DJI_BLACKLIST_DETAIL:" where upper(country_code) = 'CHINA' and trim(dji_name) is not null and trim(dji_id_no) is not null"
