Review comment:
@Liangda-w “(PCTFREE NUMBER_ | PCTUSED NUMBER_ | INITRANS NUMBER_ |
storage clause)* ” is more suitable, but if we change physicalAttributesClause
like this, it will happen as bellow:
"rule oidIndexClause contains a closure with at least one alternative that
can match an empty string".
@tristaZero how could we resolve this problem?
