PHP Location::QueryCount方法代码示例

 /**
  * Main utility method to aid with data binding.  It is used by the default BindAllRows() databinder but
  * could and should be used by any custom databind methods that would be used for instances of this
  * MetaDataGrid, by simply passing in a custom QQCondition and/or QQClause. 
  *
  * If a paginator is set on this DataBinder, it will use it.  If not, then no pagination will be used.
  * It will also perform any sorting (if applicable).
  *
  * @param QQCondition $objConditions override the default condition of QQ::All() to the query, itself
  * @param QQClause[] $objOptionalClauses additional optional QQClause object or array of QQClause objects for the query		 
  * @return void
