DBIx::Class::Storage::DBI::NoBindVars(3)r Contributed Perl Documentation::Class::Storage::DBI::NoBindVars(3)



NAME
       DBIx::Class::Storage::DBI::NoBindVars - Sometime DBDs have poor to no support for bind variables

DESCRIPTION
       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

METHODS
   connect_info
       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.

   _prep_for_execute
       Manually subs in the values for the usual "?" placeholders.

   interpolate_unquoted
       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       The return value is interpreted as: true - do not quote, false - do quote.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.

        WARNING!!!

        Always validate that the bind-value is valid for the current datatype.
        Otherwise you may very well open the door to SQL injection attacks.

   _prep_interpolated_value
       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)
