In contrast with the graphical query designer , this query design tool does not validate query syntax during query design 与图形查询设计器相比，此查询设计工具无法在查询设计过程中验证查询语法。
The graphical query designer is a query design tool used in several microsoft products and in other sql server components 图形查询设计器是在多种microsoft产品及其他sql server组件中使用的查询设计工具。
To use the graphical query designer , you must toggle the generic query designer button on the report designer toolbar : for more information , see 若要使用图形查询设计器，必须切换报表设计器工具栏上的通用查询设计器按钮：
Graphical query execution plans enable developers to easily see query execution plans and so better understand potential query performance issues 使用图形查询执行计划，开发人员可以轻松地查看查询执行计划，因此，可以更好地了解潜在的查询性能问题。
The toolbar provides options for switching to the graphical query designer , running the query , refreshing the pane , and managing the dataset : for more information , see 工具栏提供了用于切换到图形查询设计器、运行查询、刷新窗格以及管理数据集的选项：
Calculated fields have expression - based values evaluated when the query runs . you can also create filters to limit the data at the source before it is sent to a report 如果您要改用较为熟悉的图形查询设计器，请在“数据”视图工具栏上切换“通用查询设计器”按钮。
Use the graphical query designer to browse the metadata on the data source to interactively design a query or to view a list of stored procedures or tables on the data source 与图形查询设计器不同的是，通用查询设计器不检查查询语法或调整查询的结构。有关详细信息，请参阅
The data view in report designer is a query designer used for building datasets that retrieve metadata about a data source , which you use to design your report layout 对于图形查询设计器不支持的数据源、您不希望由图形查询设计器自动更正的查询以及表达式，可以使用通用查询设计器。
At present , more and more users are unsatisfied with the simple functions , such as graph query , plotting , so powerful spatial analysis is demanded for gis in more projects in order to provide exact and timely decision for manager 目前,越来越多的用户已不甘于完成简单的图形查询、绘图等功能,更多的项目要求gis具有强大分析功能,以使开发的系统为管理者提供准确及时的辅助决策和支持。
The system stores spatial data and characteristic data into central database , and provides services to users in server / client mode . as the research emphases of this thesis , several key sub - systems are designed and realized . the digital map input and maintenance subsystem performs format conversion , editing and updating of spatial data ; the rail - track video playing subsystem uses video recording as reference data , then plays , inquires and traces the corresponding frames in synchronous to the scaled mileage , realizing the query of the active picture frames ; the digital map query subsystem fulfills the map query , preview and spelling of digital map orthograph 其中，地形图输入与维护实现了数字地图的格式转换、编辑处理以及空间数据的更新操作，解决了不同格式空间数据的互相转换问题；线路录象播放将线路录像数据作为系统的一种索引数据，活动影像的画面与里程相对应，实现了基于线路录像的播放、查询和检索的功能，实现了基于活动画面的查询检索功能；数字地图子系统完成了图形查询、数字地图与线路正射图像浏览、图幅拼接等功能。
