How can I pass object to procedure from trigger? I am using mysql 5.6.
After insert or update, inside the trigger I am calling procedure, So how can i  pass NEW and OLD object from trigger to procedure ?
I found this: SOURCE


  There is great reason why you should never call stored procedures from
  within triggers.
  
  Triggers are, by nature, stored procedures. Their actions are virtually hard to roll back. Even if all underlying tables are InnoDB,
  you will experience a proportional volume of shared row locks and
  annoying intermittency from exclusive row locks. Such would be the
  case if triggers were manipulating tables with INSERTs and UPDATEs
  being stagnated to perform heavy duty MVCC inside each call to a
  trigger.
  
  Don't forget that Triggers require overhead. In fact, According to MySQL Stored Procedure Programming, page 256 under the head "Trigger
  Overhead" says the following:
  
  It is important to remember that, by necessity, triggers add overhead
  to the DML statement to which they apply. the actual amount of
  overhead will depend upon the nature of the trigger, but --- as all
  MySQL triggers execute FOR EACH ROW --- the overhead can rapidly
  accumulate for statements that process large numbers of rows. You
  should therefore avoid placing any expensive SQL statements or
  procedural code in triggers. An expanded explanation of trigger
  overhead is given on pages 529-531. The concluding point from that
  section states the following:
  
  The lesson here is this: since the trigger code will execute once for
  every row affected by a DML statement, the trigger can easily become
  the most significant factor in DML performance. Code inside the
  trigger body needs to be as lightweight as possible and -- in
  particular -- any SQL statements in the trigger should be supported by
  indexes whenever possible.
