UniDAC and Ping

I previously used to access to MySQL-server components ZEOSLib (http://zeos.firmos.at)
To test connection, there was a function Ping (TZConenction.Ping)
In TUniConnection no feature Ping. But Ping is in TMySqlSession.
As of TUniConnection allocate TMySqlSession to perform Ping?

The TMyConnection component of MyDAC has the Ping method, but TUniConnection doesn't have this method because it is server specific and doesn't make sense for other servers.

But how do Ping, when TUniConnection used to connect to MySQL?

UniDAC doesn't allow to execute this method. As a workaround you can execute any simple query, like SELECT 0, and check the result.

Maybe in future versions can be done something like that

Code: Select all

(UniConnection1.CurrentSession as TMySqlSession).Ping

Thank you for your inquiry. We will investigate the possibility of adding this functionality in the future.
