In my experience it is is best to use a two-step approach: Prior to the partition exchange you should build the same local indexes on the temporary table. Method 1. The Global & Local indexes are mainly related to Oracle table partitions. How to resolve ORA 14287 cannot REBUILD a partition? Rebuild index using alter index rebuild partition. Index partitioning is transparent to all the SQLs. For existing partition indexes, you could do something like this: select 'alter index ' || INDEX_OWNER || '. Each command creates the partial marked indexes on the partition: alter table mytab modify partition P100 indexing ON; alter table mytab modify partition P101 indexing ON; alter table.
