-~~Title: Loop a List~~ 
  
-Here's a simple loop example: 
- 
-{{:​workflow:​example:​loop_a_list.png?​nolink|}} 
- 
-The first step (Delete Statement) deletes all records of a heroes database table. The next step (REST Get) loads a list of heroes from an example [[https://​admin:​admin@cloud.sibvisions.com/​heroes/​services/​rest/​Heroes/​HeroesWorkScreen/​data/​heroes|REST service]]. The service returns a JSON array of heroes with ID and NAME as attributes, e.g.: 
- 
-<file json> 
-[ 
- ​{"​ID":​1,"​NAME":"​Superman"​},​ 
- ​{"​ID":​2,"​NAME":"​Batman"​},​ 
- ​{"​ID":​4,"​NAME":"​Rambo (John)"​},​ 
- ​{"​ID":​5,"​NAME":"​Captain America"​},​ 
- ​{"​ID":​6,"​NAME":"​Wolverine (X-Men)"​} 
-] 
-</​file>​ 
- 
-and stores the list in a variable with the name **Heroes**. The loop list step iterates all **heroes** and continues as long as there are entries. If all entries were processed, the final step (Client Call) will be executed to reload the client application.
