VALUES - Advanced SQL Engine - Teradata Database

Displays the create text for the specified database object and the detailed statistics that have been collected on it using a COLLECT STATISTICS statement.

You must specify the VALUES keyword to report the detailed statistics for the specified database object.

SEQUENCED

Report a sequence number with detailed statistics output.

This option is not valid unless you also specify VALUES.

Because the spool file size for each group of statistics is limited to a maximum of 64KB, the database uses the sequence numbers within each set of statistics reported to order the spool file chunks within each set. See “SHOW STATISTICS” in Teradata Vantage™ - SQL Data Definition Language Detailed Topics , B035-1184 for more information about this.

The sequence numbers are required by the Archive/Recovery utility to identify the boundaries of Optimizer statistics that have been archived.

Example: SHOW STATISTICS with a VALUES Clause for a Table With Statistics Collected on a Geospatial Column

Consider the following COLLECT STATISTICS request.

     COLLECT STATISTICS
       COLUMN o_warehouseloc
     ON orders;

The following SHOW STATISTICS request reports COLLECT STATISTICS SQL text with a VALUES clause for column o_warehouseloc, a geospatial column that contains points that specify the longitude and latitude for the warehouse from which the order is to be shipped.

     SHOW STATISTICS VALUES COLUMN o_warehouseloc ON orders;
     COLLECT STATISTICS 
                COLUMN "o_warehouseloc" 
     ON "orders"
       VALUES
