DBIx::Class::Storage::DBI::NoBindVars - Sometime DBDs have poor to no support for bind variables
This class allows queries to work when the DBD or underlying library does not support the usual ? placeholders, or at least doesn't support them very well, as is the case with DBD::Sybase
We can't cache very effectively without bind variables, so force the disable_sth_caching setting to be turned on when the connect info is set.
Manually subs in the values for the usual ? placeholders.
This method is called by "_prep_for_execute" for every column in order to determine if its value should be quoted or not. The arguments are the current column data type and the actual bind value. The return value is interpreted as: true - do not quote, false - do quote. You should override this in you Storage::DBI::<database> subclass, if your RDBMS does not like quotes around certain datatypes (e.g. Sybase and integer columns). The default method returns false, except for integer datatypes paired with values containing nothing but digits.
Always validate that the bind-value is valid for the current datatype.
Otherwise you may very well open the door to SQL injection attacks.
Given a datatype and the value to be inserted directly into a SQL query, returns the necessary string to represent that value (by e.g. adding a '$' sign)
