Note

If one or more tables with the same (case-sensitive) names as the specified tables already exist in the context of the database, the command returns success without changing the existing tables, even in the following scenarios:

The folder or docstring parameters are specified with values different from the ones set in the existing tables

Any specified tables that don't exist are created.

Example

.create tables 
  MyLogs (Level:string, Timestamp:datetime, UserId:string, TraceId:string, Message:string, ProcessId:int32),
  MyUsers (UserId:string, Name:string)
