Implements org.hibernate.stat.QueryStatistics.getExecutionCount.

queries executed to the DB
public long
getExecutionMaxTime()

Implements org.hibernate.stat.QueryStatistics.getExecutionMaxTime.

max time in ms taken by the execution of this query onto the DB

Implements org.hibernate.stat.QueryStatistics.getExecutionMinTime.

min time in ms taken by the execution of this query onto the DB
public long

Returns:

The number of rows cumulatively returned by the given query; iterate and scroll queries do not effect this total as their number of returned rows is not known at execution time.
getExecutionRowCount()

Implements org.hibernate.stat.QueryStatistics.getExecutionRowCount.

Number of lines returned by all the executions of this query (from DB) For now, org.hibernate.Query#iterate() and org.hibernate.Query#scroll()() do not fill this statistic
