I have objects Opportunity, OpportunityLineItem,  

CustomObject1( OpptyID , OwnerType, UserID)

Custom Object2(OwnerType, OptyLineItemType)

I wanted to have a query to get data from Opportunity and OpportunityLineitem based on ( Opportunity.Id=CustomObject1.OpptyId) and CustomObject1.OwnerType=CustomObject2.OwnerType and OpportunityLineItem.LineItemType=Custom Object2.OptyLineItemType)

 also aggregate the lines by  UserID of CustomObject1.

Please let me know if there is a workaround or I can use a single query. 

thanks in advance.

I am using URL parameters and then read the parameter like following.

String strval=Apexpages.CurrentPage.getParameters().get('str');

sobj.property=strval;

Then passing the value to the query or sobject to update.

I am not sure how to make it safe from XSS /soql injection vulnerability.

Please send me a code snippet if you have thanks in advance
