Methods

__construct

ezcPersistentFindWithRelationsQuery __construct( $query , string $className , $relations )

Creates a new persistent find query.

Creates a new persistent find query from the query object $q and the given $className. $relations defines, which related objects should be fetched by this query.

Parameters:

Name	Type	Description
`$query`	ezcQuerySelect
`$className`	string
`$relations`	array(string=>ezcPersistentRelationFindDefinition)

Redefinition of:

Method	Description
`ezcPersistentFindQuery::__construct()`	Creates a new persistent find query.

where

ezcQuerySelect where( string|array(string) $... )

Adds a where clause with logical expressions to the query.

where() accepts an arbitrary number of parameters. Each parameter must contain a logical expression or an array with logical expressions. If you specify multiple logical expression they are connected using a logical and.

Multiple calls to where() will join the expressions using a logical and.

Example:

$q->select( '*' )->from( 'table' )->where( $q->expr->eq( 'id', 1 ) );

Note, if you add a WHERE clause to this query, the fetched related objects will not be fetched into the ezcPersistentIdentityMap used as a typical related object set, but as a named set.

Parameters:

Name	Type	Description
`$...`	string\|array(string)	Either a string with a logical expression name or an array with logical expressions.

Exceptions:

Type	Description
`ezcQueryVariableParameterException`	if called with no parameters.

__call

mixed __call( string $methodName , array $arguments )

Delegate to inner $query object.

This query object does not allow any other calls than {where()} and {groupBy()}. Therefore, this method throws an exception, for any other call.

Parameters:

Name	Type	Description
`$methodName`	string
`$arguments`	array

Exceptions:

Type	Description
`RuntimeException`	For any call.

Redefinition of:

Method	Description
`ezcPersistentFindQuery::__call()`	Delegate to inner $query object.
