[rules-users] Use of a DAO in LHS

[BINET JEAN-BAPTISTE]

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
