Hi,

I receive this error while running the following :

SQL> DECLARE

  2

  3  VARIABLE v_task  :='TÂCHE_338';

  4

  5  BEGIN

  6    DBMS_SQLPA.execute_analysis_task(

  7      task_name       => :v_task,

  8      execution_type  => 'test execute',

  9      execution_name  => 'after_change');

10  END;

11  /

SP2-0552: Bind variable "V_TASK" not declared.

How should I write that code ?

Thank you.
