Displays the collection execution history for a specified completed run, commands list, user object names, or time period.
Definition
REPLACE PROCEDURE TDSTATS.SelectStatsExecutionHistory (IN RunID BIGINT, IN CmdListID BIGINT, IN CmdListName VARCHAR(128) CHARACTER SET UNICODE, IN DataBaseName VARCHAR(128) CHARACTER SET UNICODE, IN TableName VARCHAR(128) CHARACTER SET UNICODE, IN ObjectListName VARCHAR(128) CHARACTER SET UNICODE, IN StartTime TIMESTAMP(6) WITH TIME ZONE, IN EndTime TIMESTAMP(6) WITH TIME ZONE) . . . ;
Input Parameters
| Parameter | Description |
|---|---|
| RunID | System assigned ID for the results from a given execution of RunCollect or RecollectTable. To show the results from a specific execution run, you must specify a value for this input parameter. RunID is an output parameter for RunCollect and ReCollectTable. If you specify NULL, the results from all run operations in the TDSTATS.CommandsHistoryTbl table will be displayed.
|
| CmdListID | System assigned commands list ID. |
| CmdListName | User assigned commands list name. |
| DataBaseName | Name of the database. DataBaseName limits the results to completed collections on the database you specify. |
| TableName | Name of the table. TableName limits the results to completed collections on the table you specify. |
| ObjectListName | Name of the object list. ObjectListName limits the results to completed collections on the object list (that is, one or more database names or fully qualified table names where each name entry may optionally contain wildcard characters) you specify. For more information about this input parameter, see “Usage Notes” or CreateObjectList. |
| StartTime | Start time. StartTime limits the results to those collections submitted on or after the time you specify. |
| EndTime | End time. EndTime limits the results to those collections completed on or before the time you specify. |
Usage Notes
The SelectStatsExecutionHistory external stored procedure displays the historical results from already completed calls to RunCollect or RecollectTable.
You can call RunCollectReport to monitor the results for an in-progress RunCollect.
Returning Result Set
The output of this external stored procedure is in the form of a stored procedure dynamic result. That is, the external stored procedure can return result sets to the client application or to the caller of the external stored procedure (in addition to consuming the result sets itself) upon completion of the external stored procedure.
For more information about stored procedure dynamic result sets, see Teradata Vantage™ SQL External Routine Programming , B035-1147 .
Displaying Execution Results
| To display ... | You must specify a value for ... |
|---|---|
| results for a particular execution | RunID. |
| past execution results for a particular command list | CmdListID or CmdListName. |
| past execution results from collections on a particular user object | both DatabaseName or TableName |
| past execution results from collections on a particular named object list |
ObjectListName that was previously created by the CreateObjectList and AddObjectListEntry external stored procedures. ObjectListName usage is mutually exclusive with DatabaseName and TableName . When you specify a value other than NULL for ObjectListName , DatabaseName and TableName must be NULL. |
| execution results for a particular date range | both StartTime and EndTime. |
Output Parameters
| Parameter | Description |
|---|---|
| RunID | System assigned ID of the RunCollect results being reported. |
| CmdListID | Commands list ID from the collection executed. |
| CmdListName | Commands list name, if assigned, from which the collection was executed from. |
| StartTime | Time when the collection was submitted for execution. |
| EndTime | Time when the collection completed execution. |
| DatabaseName | Database on which the collection was performed. |
| TableName | Table on which the collection was performed. |
| Status | Possible values:
|
| Skipped | Possible values:
|
| CollectText | SQL text of the COLLECT STATISTICS statement. |
| ErrorText | Error message if the Status output parameter returns an E. For details, see the Status output parameter. |
Example: Using SelectStatsExecutionHistory
The following example shows how to display the past execution results for the commands list named MyCmdslist.
CALL TDSTATS.SelectStatsExecutionHistory(NULL,NULL,'mycmds',NULL,NULL,NULL,NULL,NULL);
*** Procedure has been executed.
*** Warning: 3212 The stored procedure returned one or more result sets.
*** Total elapsed time was 1 second.
*** ResultSet# 1 : 6 rows returned by "TDSTATS.SELECTSTATSEXECUTIONHISTORY".
