Yes! All the time, but with some variation. Let me explain by rewriting your query:

    select t1.col1,
           t2.col2,
           t3.col3
      from table1 t1
     inner join table2 t2 on t1.col2 = t2.col1
     inner join table3 t3 on t1.col3 = t3.col1 and t3.col2 = something_else
     where 1 = 1
       and t1.col1 > 0 
       and t2.col2 <> t1.col4
     order by col2
     limit 100

My logic is that I: 1 - There should be a clean vertical line between the select/from/inner/where/etc keyboards to the right hand side for clean alignment. 2 - I always use the where 1 = 1 syntax so that I can easily comment out the following conditions while testing.

And thanks for not capitalising the keywords :-)
