Some of the else if lines exceeded 100 characters, so should have been
split; and some lines already were split. So each whole chain should
have had braces on its bodies. Instead make it a switch, as this makes
it more evident what's going on in any case. Furthermore, as each
branch did the same thing with dbType-specific strings, change to just
setting QLatin1String variables, so that the rest of the code needn't
be duplicated in each branch; it can simply be done once after the
switch, using the string's .arg() to embed fragments. In the process
break up the SQL query strings more gracefully, purge spaces just
inside C++ parentheses.
