| 2. | To add a global query to a dataset
向数据集添加全局查询 |
| 3. | Global queries are sql queries that return either a single scalar value or no value
“全局查询”是返回单个（标量）值或不返回任何值的sql查询。 |
| 4. | You add global queries by running the tableadapter query configuration wizard from within the
可以通过从“数据集设计器”运行“ tableadapter查询配置向导”添加全局查询。 |
| 5. | Therefore , through the self - defined globe - sql , broker manipulate sql so as to control every table in database
再通过自定义的全局查询语言，代理完成sql操作，以达到操作数据库中各表的目的。 |
| 6. | Dragging a query onto a table adds the query to that table , whereas dragging a query onto an empty area of the
将查询拖动到表上可将该查询添加到该表，而将查询拖动到“数据集设计器”的空白区域上会创建全局查询。 |
| 7. | The ability to aggregate arbitrary numbers of such wsdl rdf descriptions into a database , and do global queries is one immediate benefit of this rdf mapping for developers
对于开发者来说，这一rdf映射的直接好处在于能够把任意数目的这类wsdl / rdf描述聚集到数据库并进行全局查询。 |
| 8. | This paper improves on the existent methods of schema integration by analysis and comparing them and combining xml with them . moreover , the global schema and mapping rules according to xml standard are generated
本文在分析比较已有模式集成方法的基础上，结合xml作为数据模型描述语言的优势，将xml技术应用于模式集成，改进了已有模式集成方法，生成符合xml标准的全局模式和模式映射规则，为全局查询处理奠定了基础。 |
| 9. | The paper also puts forth concrete solving methods about the following key problems in the realization of system : ( 1 ) middle operation logic layer is separated from the system . designing the three - architecture for the integrated system . ( 2 ) designing the uniform general data - describing mode
提出的主要解决方案有： ( 1 )从系统中分离出中间业务逻辑层，形成三层体系结构； ( 2 )设计了统一的公共数据描述模式； ( 3 )设计了基于sql的全局查询语言； ( 4 )实现了集成系统的动态生成。 |
