The phase of sql query execution is as follows.
1)Syntax Checking: Query will be checked if it is syntactically correct.
2)Semantic Checking:Query will be checked for user has rights on tables etc.
3)Cursor sharing:query will be checked against cursor sharing if soft parse can be done or hard parse required.
4)The creation of cost based decision tree for possible plans.
5)The execution of lowest cost execution plan.
6)Binding the execution plan.
7) Executing the query and fetching the rows.
