示例1: compileFrom

 /**
  * Compile the "from" portion of the query
  * which in cypher represents the nodes we're MATCHing
  *
  * @param  \Vinelab\NeoEloquent\Query\Builder  $query
  * @param  string  $labels
  * @return string
  */
 public function compileFrom(Builder $query, $labels)
 {
     // Only compile when no relational matches are specified,
     // mostly used for simple queries.
     if (!empty($query->matches)) {
         return '';
     }
     // first we will check whether we need
     // to reformat the labels from an array
     if (is_array($labels)) {
         $labels = $this->prepareLabels($labels);
     }
     // every label must begin with a ':' so we need to check
     // and reformat if need be.
     $labels = ':' . preg_replace('/^:/', '', $labels);
     // now we add the default placeholder for this node
     $labels = $query->modelAsNode() . $labels;
     return sprintf("MATCH (%s)", $labels);

示例2: compileUpdateLabels

 /**
  * Compile an statement to add or drop node labels
  *
  * @param  \Vinelab\NeoEloquent\Query\Builder  $query
  * @param  array $labels labels as string like :label1:label2 etc
  * @param  array $operation type of operation 'add' or 'drop'
  * @return string
  */
 public function compileUpdateLabels(Builder $query, $labels, $operation = 'add')
 {
     if (trim(strtolower($operation)) == 'add') {
         $updateType = 'SET';
     } else {
         $updateType = 'REMOVE';
     }
     // Each one of the columns in the update statements needs to be wrapped in the
     // keyword identifiers, also a place-holder needs to be created for each of
     // the values in the list of bindings so we can make the sets statements.
     $labels = $query->modelAsNode() . $this->prepareLabels($labels);
     // Of course, update queries may also be constrained by where clauses so we'll
     // need to compile the where clauses and attach it to the query so only the
     // intended records are updated by the Cypher statements we generate to run.
     $where = $this->compileWheres($query);
     // We always need the MATCH clause in our Cypher which
     // is the responsibility of compiling the From component.
     $match = $this->compileComponents($query, array('from'));
     $match = $match['from'];
     return "{$match} {$where} {$updateType} {$labels} ";
 }
