title: Is it possible to evaluate expression in stored procedure?
body: <p>I have a two table like </p>
  
  <pre> 
  tbl1
  +-------+---------+ 
  | id    | number  | 
  +-------+---------+ 
  | a001  |  001    | 
  | a002  |  002    |
  | a003  |  003    |
  | a004  |  004    |
  | a005  |  002    |
  +-------+---------+
  
  tbl2
  +----+-----------------------------------+------------+ 
  | id | Extression                        | True/False | 
  +----+-----------------------------------+------------+
  | 01 | `a003=a001+ a002`                 |            |
  | 02 | `a004=a001+ a002`                 |            |
  | 03 | `a004 + a005 =a001 + a002 + a003` |            |
  +----+-----------------------------------+------------+
  </pre>
  
  <p>I want to update True/False column based on result of expression.In this case 01 is true,02 is false and 03 is true.
  I have done this in c# code. But due to limitation of runnig exe through job I want to do this by procedure in oracle.
  Is this possible ??</p>
