1 query.inc public MergeQuery::useDefaults(array $fields)

Specifies fields for which the database-defaults should be used.

If you want to force a given field to use the database-defined default, not NULL or undefined, use this method to instruct the database to use default values explicitly. In most cases this will not be necessary unless you are inserting a row that is all default values, as you cannot specify no values in an INSERT query.

Specifying a field both in fields() and in useDefaults() is an error and will not execute.

Parameters

$fields: An array of values for which to use the default values specified in the table definition.

Return value

MergeQuery: The called object.
