      .status(parameter) → Hash)  
      .status(parameter, reset_flag = false) → Hash)  
    

  



  

    

Queries the SQLite3 library for run-time status information. Passing a truthy reset_flag will reset the highwater mark to the current value.


Parameters



  • 

    parameter (Integer, ::SQLite3::Constants::Status): The status parameter to query.
    

  • 

    reset_flag (Boolean): Whether to reset the highwater mark. (default is false)
    



Returns



A Hash containing :current and :highwater keys for integer values.
