Hello,
I have a question,maybe you know the answer. I know if I create primary key(PK_TABLE1) of TABLE1, Oracle will create a unique index(PK_TABLE1) for the table. Alter table TABLE1 add constraint FK_TABLE1 foreign key (COL1) reference TABLE2 (COL1),
I couldn't see any index object for this foreign key. But if I create a index named FK_TABLE1 with COL1 of TABLE1, Will it be faster in searching the TABLE1 references TABLE2?? Could anyone give me some suggestion?
