Open the view.

Open the Dependencies panel.

There's my list of tables.

Or...that's right, you wanted COLUMNS as well.

Do a SELECT * FROM for your view in the SQL Worksheet. Mouse over the SELECT keyword.

<a href="https://i.stack.imgur.com/L8hwL.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/L8hwL.png" alt="enter image description here"></a>

This invokes the SQL Text Expansion feature in the database. Note that if your underlying SQL includes wildcards, generating the DDL won't help you with column names.

If I click on the text of the view source after the mouse-over, you'll get the actual SQL in your worksheet.

For example this is what I get for 'SELECT * FROM EMP_DETAILS_VIEW'

<pre><code>SELECT "A1"."EMPLOYEE_ID" "EMPLOYEE_ID",
 "A1"."JOB_ID" "JOB_ID",
 "A1"."MANAGER_ID" "MANAGER_ID",
 "A1"."DEPARTMENT_ID" "DEPARTMENT_ID",
 "A1"."LOCATION_ID" "LOCATION_ID",
 "A1"."COUNTRY_ID" "COUNTRY_ID",
 "A1"."FIRST_NAME" "FIRST_NAME",
 "A1"."LAST_NAME" "LAST_NAME",
 "A1"."SALARY" "SALARY",
 "A1"."COMMISSION_PCT" "COMMISSION_PCT",
 "A1"."DEPARTMENT_NAME" "DEPARTMENT_NAME",
 "A1"."JOB_TITLE" "JOB_TITLE",
 "A1"."CITY" "CITY",
 "A1"."STATE_PROVINCE" "STATE_PROVINCE",
 "A1"."COUNTRY_NAME" "COUNTRY_NAME",
 "A1"."REGION_NAME" "REGION_NAME"
 FROM (
 SELECT "A7"."EMPLOYEE_ID" "EMPLOYEE_ID",
 "A7"."JOB_ID" "JOB_ID",

<code>select * from all_dependencies where type = 'VIEW' and name = :your_view</code>

Is there any easy way to find the tables and columns used to create a view ? 

i opened all the views and tried to find the tables and column used in it, but I feel I might have missed something. Is there any commands that displays all the columns and tables used in a view ?

有什么简单的方法可以找到用来创建视图的表和列吗？我打开了所有的视图，并试图找到其中使用的表和列，但我觉得我可能遗漏了一些东西。有没有什么命令可以显示视图中使用的所有列和表？
