| 19:04.58 | akm1 | Hi, Is there a way to alias table columns in storm ? |
| 19:57.38 | *** join/#storm shaunm (n=shaunm@c-98-212-133-244.hsd1.il.comcast.net) |
| 23:23.30 | jkakar | akm1: Yes, you probably want ClassAlias. |
| 23:24.08 | jkakar | akm1: You can use it like so, from storm.locals import ClassAlias; alias = ClassAlias(SomeClass); store.find(SomeClass, alias.some_column == 10) |
| 23:24.56 | jkakar | akm1: It's described in the tutorial, which is a good start-up document if you haven't already found it: https://storm.canonical.com/Tutorial#Aliases |
| 23:26.04 | akm1 | jkakar, i think ClassAlias is used for tables, i want to create an alias for table attribute.. |
| 23:26.58 | jkakar | akm1: Right, I understand. You can use ClassAlias to wrap a table, and then access the table attribute you want as an attribute of the alias. |
| 23:27.05 | jkakar | akm1: Or am I missing something? |
| 23:28.02 | jkakar | akm1: Maybe what you want is storm.expr.Alias (though, if you use multiple tables, you could have problems with name collisions). |
| 23:29.55 | akm1 | jkakar, thanks..this is what i need .. |
| 23:30.31 | jkakar | akm1: My pleasure. :) |
