You also get a text describing "Incorrect syntax near ....". Line 16 contains "HPD_HELP_DESK.Closure_Manufacturer" - does this field exists in table?
What strikes me the most is, that you don't join the tables by telling the compiler how the tables are "connected".
Also in the from sections, you "select * from ....". It had been enough to "just" mention the tablename (and alias).
