Which issue this PR fixes
251ab85fixes:#71: session ls fails with "Error 1390: Prepared statement contains too many placeholders"#72and#62(1695d4f) as they are mandatory to test.What this PR does / why we need it
If the mySQL database held too many records, the
session lscommand failed with an error message. The hard limit of records by query in mySQL is 65,535.It now queries by batch of 60000 to solve the problem.
I also added an option to only list active session (--active, -a) to compensate for the increased time taken by the query on bigger databases.
