Summary :
trigger type, sample custom triggers

Service manager provides triggers and it could be used effectively if well-tailored.

This dosoment shows various sample custom triggers and SM developer could use it as reference when building custom triggers.

 

Solution

1. trigger type
 . 1 - Before Add - When adding a new record to this file, launch the application prior to committing the addition.
 . 2 - After Add - When adding a new record to this file, launch the application after committing the addition.
 . 3 - Before Update - When modifying a record in this file, launch the application prior to committing the change.
 . 4 - After Update - When modifying a record in this file, launch the application after committing the change.
 . 5 - Before Delete - When deleting a record in this file, launch the application prior to performing the deletion.
 . 6 - After Delete - When deleting a record in this file, launch the application after performing the deletion

2. naming custom triggers
 - trigger runs by name order.
   It is better to have name starting by 'z_xxxx' if wish to run lastly.
   It is better to have name starting by 'A_xxxx' if wish to run firstly.
   This is because 'A' is first character and 'z' is last character in ASCII code.

3. file variables for each trigger type in Java Script
 - add, delete trigger : record
 - update trigger    : record, oldrecord
   . record     // updated information
   . oldrecord  // previous information before update

4. Basic Java Script
 - all columns' value of current record
  record
 - one of columns' value in current record
  record[brief_description]     // recommend, always working
  record.brief_description       // record.class makes issue in testing because class is real column but also reserved word in Java script
 - other variables
  vars.$lo_user_name
 
 
5. Sample triggers

A. monitor file's activity
 1) ex: monitor UPDATE in probsummary file
 2) add custom trigger in triggers file
  - Trigger Name: probsummary_before_update   // anyname
  - Table Name: probsummary
  - Trigger Type: 3 - Before Update
  - Application :
  - Script :
  print("### trigger execution: probusmmary_before_update (messagebox)");
  vars.$L_void=system.functions.rtecall("log",vars.$L_rc,
         "### trigger execution: probusmmary_before_update (sm.log)", "NULL");
  > click 'save' then click 'compile'
 3) search any IM ticket and then update it
  - in message box,
    ### trigger execution: probusmmary_before_update (messagebox)    
  - in sm.log
    3904(  3724) 10/01/2013 10:58:42  RAD I ### trigger execution: probusmmary_before_update (sm.log)
  --> this message is shown even though no debugging options in sm.ini
 
B. mointor file's value by trigger
  - add logics into trigger, probsummary_before_update
  print("### updated record:" + record );
  vars.$L_void=system.functions.rtecall("log",vars.$L_rc,
          "### updated record:" + record , "NULL");
  - in message box,
   ### updated record:[C++ object Datum] - probsummary={["IM10002", "incident", '09/02/07 01:51:00', "Jurr.Fleijs", "2", "3", '09/30/13 20:41:00', "Network", , , , "updat

C. monitor file's value by trigger ( before/after update )
   - add logics into trigger, probsummary_before_update
     print("### old record:" + oldrecord);
     vars.$L_void=system.functions.rtecall("log",vars.$L_rc,
           "### old record:" + oldrecord, "NULL");

     print("### new record:" + record);
     vars.$L_void=system.functions.rtecall("log",vars.$L_rc,
           "### new record:" + record, "NULL");

  - in message box,

     // below code is also valid in "4- After Update" trigger type
