The Live table presents the current value of the specified tag(s).
Note: In certain situations, data can bypass the Live table. These situations include:
- Receiving non-streamed original data (store/forward or CSV);
- Receiving revision data for a Latest value;
- Receiving no new streamed values after Historian was shut down and disabled, or
after the computer was rebooted.
The format of the Live table is as follows. The DateTime column will indicate the time the value was received.

Note: The AnalogLive, DiscreteLive, and StringLive tables are provided for backward compatibility and can only accept tagnames in the SELECT statement that are of the same type; that is, you can't mix the tag types in the query. The Live table, however, can accommodate a mixture of tag types and should be used instead of the AnalogLive, DiscreteLive, or StringLive tables.
