RequestLive is a request that a SELECT query returns an updatable (or live)
or read-only result set from the database back-end.
//RequestLive属性是要求是从后台数据库返回的可更改的结果集还是只读的结果集。
A False value for RequestLive (the default) causes the result set to
always be read-only. No request is made to the database back-end to
return an updatable result set.
//RequestLive属性缺省值为false,结果集为只读。不能使用后台数据库返回可更改的结果集。
A True value for RequestLive is a request to database back-end to
return an updatable result set.
//RequestLive属性值为true,后台数据库返回可更改的结果集。
A True value for RequestLive is a request for an updatable result set.
It does not guarantee that the database back-end will return
an updatable result set.
//设置为TURE不能保证后台数据将返回的是可编辑的结果集。。
See the documentation for the specific database system used
for the criteria needed for a live query result set. If the
database cannot return an updatable result set, a read-only
result set is returned instead. This is done automatically
and usually without error. Some database systems may raise
an exception on requests for live result sets that cannot be
fulfilled. Check the success of the request by inspecting thr dataset
component CanModify property.
