Class

UpdateQuery

General class for an abstracted UPDATE operation.

Code

public function execute() {
 // Expressions take priority over literal fields, so we process those first
 // and remove any literal fields that conflict.
 $fields = $this->fields ;
 $update_values = array();
 foreach ($this->expressionFields  as $field => $data) {
 if (!empty($data['arguments'])) {
 $update_values += $data['arguments'];
 }
 unset($fields[$field]);
 }
 // Because we filter $fields the same way here and in __toString(), the
 // placeholders will all match up properly.
 $max_placeholder = 0;
 foreach ($fields as $field => $value) {
 $update_values[':db_update_placeholder_' . $max_placeholder++] = $value;
 }
 if (count ($this->condition )) {
 $this->condition 
 ->compile ($this->connection , $this);
 $update_values = array_merge ($update_values, $this->condition 
 ->arguments ());
 }
 return $this->connection 
 ->query ((string) $this, $update_values, $this->queryOptions );
