I usually create all my queries at design time but the text is set
dynamically at run time.
Having the query component on my form at design time will help me to
organize my work and of course code completion as was mentionned before.
All my database tables are defined in my units with constants as their
field names and sizes, therefore when I set the text of my queries at run
time, I use those constants. In case someday I change the name of the field
I only change the value of the constant and won't be obliged to change
anything else in the application.
The only places where query components are created at run time are in
the units where I need a local query in a procedure that will not be called
more often. But on those forms that I need to display data the query is
created at design time but the text is set and run at initialization time of
the form

Thats not a bad way to learn- I did that but I find having all the code in
the main form, eg Tform1.procedure xxx
gets clunky once the app gets a few hundred lines long. I did a large
prototype that way and it used 8 tables. I shared the same ttable component
between all tables and it got messy trying to make sure what did what when.
Once I had access to a framework of classes with queries, it became a lot
easier to maintain.
