Function based index......but I am not sure how you would use it.

Subject: question about index

Ok i guess i'm having a brain fart, someone asked me about this and for the life of me i can't figure it out. The 2nd index, what exactly is it doing with single quotes around the column name??

SQL> create table z1(x1 number, x2 date);

Table created.

SQL> CREATE INDEX X1 ON Z1 (X1); Index created.

SQL> CREATE INDEX X2 ON Z1 ('X1'); Index created.

Thanks, Joe

You can have it: Fast, Right or Cheap, pick 2 of the 3. Fast + Right is Expensive
Fast + Cheap will be incorrect.
Right + Cheap will take a while.
