I have some suggestions:

Under "Can we do better?", the example SQL uses non-standard SQL syntax 
(using a \' to escape quotes, instead of '' as defined in ISO/IEC 
9075-2:2016, section 5.3 <literal>). I suggest replacing this with 
standard syntax.

The example under "Safely composing and executing database queries" can 
be simplified by using ps.setObject(index++, value), removing the need 
for the switch (this does assume only types specified in JDBC are used, 
but on the other hand, the blanket use of String.valueOf(value) in the 
default case can cause a different set of problems).
