Basic Oracle Concepts and Programming Question:

If you log in with your Oracle account, and you want to get a list of all indexes in your schema, you can get it through the USER_INDEXES view with a SELECT statement, as shown in the following SQL script:

SELECT index_name, table_name, uniqueness
FROM USER_INDEXES WHERE table_name = 'EMPLOYEES';
<pre>INDEX_NAME TABLE_NAME UNIQUENES
----------------------- --------------------- ---------
EMP_EMAIL_UK EMPLOYEES UNIQUE
EMP_EMP_ID_PK EMPLOYEES UNIQUE
EMP_DEPARTMENT_IX EMPLOYEES NONUNIQUE
EMP_JOB_IX EMPLOYEES NONUNIQUE
EMP_MANAGER_IX EMPLOYEES NONUNIQUE
EMP_NAME_IX EMPLOYEES NONUNIQUE</pre>
As you can see, the pre-defined table EMPLOYEES has 6 indexes defined in the default sample database.
