DATA_DICTIONARY.SESSIONS.QUERY is truncated to 100 characters

[Piotr Przybylski]

There are two places containing user's current query:
* DD.PROCESSLIST.INFO - truncated to 100 characters - ok, matches MySQL SHOW PROCESSLIST
* DD.SESSIONS.QUERY - truncated to 100 characters - should return full query

To test you can run:
select query, 1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1 AS test from data_dictionary.sessions;
Output will be cut after "from dat".
