impdp system/[email protected]:1521/lcfa schemas=system directory=dir_dp dumpfile=expdpcas317.dmp logfile=impdp.log content=metadata_only

exp Import / export the specified table :
take aaa Export a table under the user , And in ccc Import under user
exp aaa/[email protected] tables=name_userinfo FILE=name_userinfo.dmp log=20220423.log;

imp ccc/[email protected] tables=name_userinfo FILE=/data/wgdata/name_userinfo.dmp log=0423.log;

Export all tables by user and exclude tables with large amount of data ：
export test Users can delete all tables and exclude several unnecessary tables
EXCLUDE Pick up IN Exactly match — Pick up LIKE Fuzzy matching
EXCLUDE Parameters can be connected at the same time IN or LIKE

Export the specified table structure
INCLUDE Parameters cannot be connected at the same time IN or LIKE, Separate operation required

impdp “/ as sysdba” SCHEMAS=test INCLUDE=TABLE:“IN (‘B_DET09_28’,‘B_DET12_31’)” CONTENT=METADATA_ONLY DIRECTORY=DIR_DP DUMPFILE=danbiao.dmp

Export the specified table structure （ Fuzzy search ）
B_DET02_ All tables at the beginning are exported
expdp “/ as sysdba” SCHEMAS=test INCLUDE=TABLE:“LIKE (‘B_DET02_%’)” CONTENT=METADATA_ONLY DIRECTORY=DATA_PUMP_DIR DUMPFILE=danbiao1.dmp LOGFILE=expdp_hntest1.log
