NAME

JsonSQL::Param::Conditions::NullCondition - JsonSQL::Param::Conditions::NullCondition object. Subclass for parsing null conditions.

VERSION

version 0.41

SYNOPSIS

This module constructs a Perl object representing the VALUES parameter of an SQL INSERT statement and has methods for generating the appropriate SQL string and bind values for use with the DBI module.

DESCRIPTION

Object properties:

_field => JsonSQL::Param::Field

Generated parameters:

$nullparameter => SQL::QueryMaker object.

METHODS

Constructor new($conditionhashref, $queryObj, $default_table_rules)

Instantiates and returns a new JsonSQL::Param::Conditions::NullCondition object.

$conditionhashref           => A hashref of the condition statement keyed by the operator.
$queryObj                   => A reference to the JsonSQL::Query object that will own this object.
$default_table_rules        => The default whitelist table rules to use to validate access when the table params 
                               are not provided to the field object. Usually, these are acquired from the table params
                               of another object (ex: the FROM clause of a SELECT statement).

Returns a JsonSQL::Error object on failure.

ObjectMethod get_sql_obj -> $nullparameter

Generates parameters represented by the object for the SQL statement. Returns:

$nullparameter            => The null condition to append to the WHERE clause. Constructed by calling the 
                             L<SQL::QueryMaker> function defined by the dispatcher with the $field parameter.
