How do I use the impdp to import a table's data from one table to another table? I am using a network link parameter.
Remote table: WRR_CASE_PAYMTH_SMRY
Table to be imported to: WRR_CASE_PAYMTH_SMRYTMP
This does not work:
impdp myAcct@dbQAT/********** schemas=WRRAPP include=table('WRR_CASE_PAYMTH_SMRY') content=DATA_ONLY network_link=dbPseudo NOLOGFILE=YES 1> impdp_04122024.log 2>&1
Please advise. Thank you.

Hi Barbara,
Thanks for the reply. I have been using the impdp with a simple import of all schema objects using a network link with success.
Example:
impdp myAcct@dbQAT/********** schemas=WRRAPP content=METADATA_ONLY network_link=dbPseudo NOLOGFILE=YES 1> impdp_04122024.log 2>&1
But haven't yet with a scenario to import for data only from one table to another table. Normally I could do something like this with the database link:
insert into WRR_CASE_PAYMTH_SMRYTMP
select * from WRR_CASE_PAYMTH_SMRY@dbPseudo;
However, not at this time because the table is complicated by partitions and subpartitions and rows is at close to half-billion rows.
