Detailed QCD interval statistics represent an internal structure that is subject to change from one release to the next in terms of content, structure, number of intervals, or format (see Teradata Vantage™ SQL Request and Transaction Processing, B035-1142 for more information). Because of this, you should avoid including such SHOW STATISTICS requests in applications that cannot easily be modified.

The same is true for detailed Optimizer interval statistics, which are used internally by the Optimizer. Optimizer statistics represent an internal structure that is subject to change from one release to the next in terms of content, structure, number of intervals, or format (see Teradata Vantage™ SQL Request and Transaction Processing, B035-1142 for more information). Avoid including SHOW STATISTICS requests for detailed Optimizer statistics in applications that you cannot modify easily.
