SQL Database to Word Document

I have a need to populate some forms that were created in MS Word with some data from our SQL database, however it involves multiple tables. Is there a way I can somehow "mail merge" in Word using SQL database with my custom sql queries as my data source? Then I could just distribute the word document to my users who need to print the info. If someone knows how to do this I would appreciate the info. If not, any other ways to do this would be helpful too. Thank you.
