Syntax

 IN  DatabaseName        VARCHAR(128) CHARACTER SET UNICODE,
 IN  TableName           VARCHAR(128) CHARACTER SET UNICODE,
 IN  ObjectListName      VARCHAR(128) CHARACTER SET UNICODE,
 IN  AnalysisID          INTEGER,
 IN  ExcludeTempTables   CHAR(1) CHARACTER SET LATIN,
 IN  MarkApproved        CHAR(1) CHARACTER SET LATIN,
 OUT AutomateId          BIGINT,
 OUT NumCopied           INTEGER

Syntax Elements

DatabaseName

Name of the database. DatabaseName limits the operation to statistics defined on the database you specify.

This input parameter may contain wildcard characters (%, _). For more information about wildcard characters, see the usage notes.

TableName

Name of the table. TableName limits the operation to statistics defined on the table you specify.

This input parameter may contain wildcard characters (%, _). For more information about wildcard characters, see the usage notes.

ObjectListName

Name of the object list. ObjectListName allows you to specify a previously defined list of objects (that is, one or more database names or fully qualified table names where each name entry may optionally contain wildcard characters) whose statistics should be automated.

For more information about this input parameter, see the usage notes or CreateObjectList.

AnalysisID

Result ID from a prior call to AnalyzeStatsUsage. For more information, see AnalyzeStatsUsage.

This input parameter cannot be NULL.

ExcludeTempTables

Possible values:

• Y or NULL. If you specify Y or NULL, the statistics defined on global temporary tables of the specified databases are excluded from automation. The default value is Y.
• N. If you specify N, the statistics defined on global temporary tables of the specified databases are automated.

MarkApproved

Possible values:

• Y or NULL. If you specify Y or NULL, the statistics defined on global temporary tables of the specified databases are excluded from automation. The default value is Y.
• N. If you specify N, the copied statistic is marked unapproved. To approve the statistic, you can call ApproveStat.

AutomateId

System supplied ID for the history results from this operation.

NumCopied

Number of statistics copied to the TDSTATS database.

Usage Notes

The AutomateUsedStats external stored procedure identifies actively used statistics that must be automated and copies them.

The summarized results from this operation are written to the AutomateHistoryTbl table. To display these results, you can call AutomateReport.

Unless you specify a value of N in the ExcludeTempTables input parameter, any statistics defined on global temporary tables are automatically excluded under the assumption that their management must be highly customized within the user application that populates them.

Wildcard Characters

For more information on how to use these wildcard characters, see the SQL LIKE clause in Teradata Vantage™ - SQL Functions, Expressions, and Predicates, B035-1145.
