    写Plugin，在PreCreate中判断当前插入的实体的记录数量。

    If your question is in CRM developing, then you can develop a plugin to catch Create message on prestage to determine the total records count. If the number is greater than the limit, throw exception.

     

    or if your question is in sql script query, just a write a trigger on the table

    Hi, Can you please help me to understand why are you having this requirement?  Are you trying to limit that number of records that a user allow to create?  CRM doesn't have that out of the box.  Modifying the SQL table is not a support approach. 

    If they need to do it through the application, there are other ways to accomplish this requirement.
