Access数据库中的子数据表属性对性能的影响
问题描述：
我已经读过如果表中的子数据表属性是自动的，那么性能会降低。你能告诉我原因吗？
I have read that if a subdatasheet property in a table is Automatic,then the performance reduces. Would you please tell me the reason?
答
如果你启用了子数据表，数据库引擎应检查子表以获取相应的数据，对吗？否则，它必须检查任何内容。
if you have subdatasheet enabled, the database engine should check child table(s) to get this corresponding data, right? Otherwise, it has to check nothing.
