[Anstis, Michael (M.)]

Hi Jean-Baptiste,
 
Here is a good (complete) example you can try following:

	On the contrary of what you said I read the documentation. And there is this sentence :
	"The next example shows how we can reason over the results of a hibernate query. The Restaurant pattern will reason over and bind with each result in turn:"
	but after there is no example !!!!
	I already tried to use the from keyword but I didn't succeed in writting a good syntax. So, that's why I ask the question.
	The only thing I succeed in is to write a function which uses my dao to do SQL query.Then I call this function with "eval" in the LHS.
	But how to use the "from" keyword ???

	I suspect you may not have read the documentation.
	 
	Take a look at the "from" keyword.

		Hello, 

		I have a DRL file in which I have a global variable representing a DAO. 
		So, I succeed in writting a rule which uses this DAO to run a SQL query 
		on the database from the RHS part. 
		But now, I would like to use my DAO in the LHS, I mean I want to fire my 
		rule only if a condition is ok on the result of my SQL query. 
		Is it possible to call a method of my DAO in the LHS part ? 
		I have not found an example. 

		Thanks. 

		Regards, 

		Jean-Baptiste
