To join tables, create a link between an object in each of the tables.
In the Query Builder window, open at least two tables.
In the first table, select the field that you want 
                        	 to link and drag it to the corresponding field of the other object.
                        	
                        	
                        	 
                     
After you finish dragging, a line connecting the linked 
                        	 fields appears.
                        	
                        	
                        	
                        	The default join type is INNER JOIN; only matching records of both 
                        	 tables will be included in the resulting dataset.
                        	 
                     
To define other types of joins, right click the link 
                        	 and select Edit... or double-click 
                        	 the link.
                              	
                              	
                              	
                              	
                              	 
The Link Properties 
                        	 dialog box appears.
                        	
                        	
                        	
                        	Using Link Properties, you 
                        	 can define join type and other link properties.
                              	 
To remove a link between objects, right-click the link line and select Remove.
