In addition to the summary information given in the table, you will get detailed execution statistics, including the minimum time, maximum time, average time, total time and the standard deviation. The standard deviation will enable you to determine whether a particular invocation of a query is outside the normal distribution of times for the given query.
Row statistics provide more detailed contents on the maximum, minimum, average, total, and standard deviation for the number of rows returned by the query, and the total size and maximum size of the data returned. The time period for the total and average figures is shown under the Summary Time Span.

To simplify the identification of a given query, you can create a query alias. The alias will be used in place of the normalized query text within the Query Analyzer table. To create an alias for a query, click the create alias link against the query. The maximum length for a query alias is 255 characters.
The Example Query tab:
The Example Details tab provides detailed information about the most expensive query executed, as determined by the execution time.
In addition to the full query, with data, that was executed, the tab shows the execution time, data, user, thread ID, client host and execution host for the given query.

The Example Explain tab enables you to view the output from
running the query with the
