why "describe" command not working in netbeans for oracle 12c

Question

I am using net-beans 8.1 and oracle 12c as database in windows 8. When i am trying the command "describe" in net-beans, it is showing the error given given below..

describe T; 

Error code 900, SQL state 42000: ORA-00900: invalid SQL statement
Line 1, column 1
Execution finished after 0 s, 1 error(s) occurred.

But the same command is working in command line.

SQL> describe T;
 Name                                      Null?    Type
 ----------------------------------------- -------- ----------------------------
 NAME                                               VARCHAR2(20)
 ID                                                 VARCHAR2(20)

SQL>

Please any one clear it to me.

Answer 1

describe is a SQL*Plus command not a SQL or PL/SQL command. It can only be used in SQL*Plus or some other client tool that happens to implement a subset of the available SQL*Plus commands. I know that SQL Developer implements describe. I'm sure other tools do as well.

You can get the same information by querying all_tab_columns

select owner, table_name, column_name, data_type, data_length, data_precision
  from all_tab_columns
 where table_name = 'T'
