Row - level and column - level tracking determines how data is transferred and how conflicts are detected during synchronization 行级和列级跟踪确定数据如何传输以及在同步过程中如何检测冲突。
At run time , row - level errors may occur when data flow components convert data , perform a lookup , or evaluate expressions 在运行时，行级错误可能在数据流组件转换数据、执行查找或计算表达式时发生。
That is , you cannot specify a very close match at the component level unless the matches at the row or join level are equally close 即，您不能在组件级指定非常接近的匹配项，除非行级或联接级的匹配项同样接近。
Additional virtual - mode events let you enable specific functionality like user edits , row addition and deletion , and row - level transactions 使用其他的虚拟模式事件可以启用特定的功能，如用户编辑、行的添加和删除以及行级事务。
Many data flow components support error outputs , which let you control how the component handles row - level errors in both incoming and outgoing data 许多数据流组件支持错误输出，这使得您可以控制组件处理传入和传出数据中行级错误的方式。
Locking at a smaller granularity , such as the row level , increases concurrency but has more overhead because more locks must be held if many rows are locked 在较小粒度（如行级）上锁定会提高并发性，但开销更多，因为如果锁定许多行，则必须持有更多的锁。
Also commits any changes to the current row if the control is bound to a data source that supports editing or virtual mode has been implemented with row - level commit scope 如果将控件绑定到支持编辑的数据源，或虚拟模式已经以行级提交范围实现，则还要提交对当前行的所有更改。
Property to " commandnotification " , which instructs asp . net to create row - level dependencies for all sql commands issued within the context of the current asp . net page 属性设置为“ commandnotification ” ，该属性值指示asp . net为当前asp . net页的上下文中发出的所有sql命令创建行级依赖项。
Property to " commandnotification " , which instructs asp . net to create row level dependencies for all sql commands issued within the context of the current asp . net page 属性设置为“ commandnotification ” ，该属性值指示asp . net为当前asp . net页的上下文中发出的所有sql命令创建行级依赖项。
Each index record contains a five - byte header that may be preceded by a variable - length header . the header is used to link together consecutive records , and also in row - level locking 每个索引记录包含一个五字节的头，在它之前还有一个变长的头。这个头是用来连接连续的记录，也用于行级锁。
