# sys.dm_pdw_sql_requests (Transact-SQL)
[!INCLUDE[tsql-appliesto-xxxxxx-xxxx-asdw-pdw_md](../../includes/tsql-appliesto-xxxxxx-xxxx-asdw-pdw-md.md)]

  Holds information about all SQL Server query distributions as part of a SQL step in the query.  
  
|Column Name|Data Type|Description|Range|  
|-----------------|---------------|-----------------|-----------|  
|request_id|**nvarchar(32)**|Unique identifier of the query to which this SQL query distribution belongs.<br /><br /> request_id, step_index, and distribution_id form the key for this view.|See request_id in [sys.dm_pdw_exec_requests &#40;Transact-SQL&#41;](../../relational-databases/system-dynamic-management-views/sys-dm-pdw-exec-requests-transact-sql.md).|  
|step_index|**int**|Index of the query step this distribution is part of.<br /><br /> request_id, step_index, and distribution_id form the key for this view.|See step_index in [sys.dm_pdw_request_steps &#40;Transact-SQL&#41;](../../relational-databases/system-dynamic-management-views/sys-dm-pdw-request-steps-transact-sql.md).|  
|pdw_node_id|**int**|Unique identifier of the node on which this query distribution is run.|See node_id in [sys.dm_pdw_nodes &#40;Transact-SQL&#41;](../../relational-databases/system-dynamic-management-views/sys-dm-pdw-nodes-transact-sql.md).|  
|distribution_id|**int**|Unique identifier of the distribution on which this query distribution is run.<br /><br /> request_id, step_index, and distribution_id form the key for this view.|See distribution_id in [sys.pdw_distributions &#40;Transact-SQL&#41;](../../relational-databases/system-catalog-views/sys-pdw-distributions-transact-sql.md). Set to -1 for requests that run at the node scope, not the distribution scope.|  
|status|**nvarchar(32)**|Current status of the query distribution.|Pending, Running, Failed, Cancelled, Complete, Aborted, CancelSubmitted|  
|error_id|**nvarchar(36)**|Unique identifier of the error associated with this query distribution, if any.|See error_id in [sys.dm_pdw_errors &#40;Transact-SQL&#41;](../../relational-databases/system-dynamic-management-views/sys-dm-pdw-errors-transact-sql.md). Set to NULL if no error occurred.|  
|start_time|**datetime**|Time at which query distribution started execution.|Smaller or equal to current time and greater or equal to start_time of the query step this query distribution belongs to|  
|end_time|**datetime**|Time at which this query distribution completed execution, was cancelled, or failed.|Greater or equal to start time, or set to NULL if the query distribution is ongoing or queued.|  
|total_elapsed_time|**int**|Represents the time the query distribution has been running, in milliseconds.|Greater or equal to 0. Equal to the delta of start_time and end_time for completed, failed, or cancelled query distributions.<br /><br /> If total_elapsed_time exceeds the maximum value for an integer, total_elapsed_time will continue to be the maximum value. This condition will generate the warning “The maximum value has been exceeded.”<br /><br /> The maximum value in milliseconds is equivalent to 24.8 days.|  
|row_count|**bigint**|Number of rows changed or read by this query distribution.|-1 for operations that do not change or return data, such as CREATE TABLE and DROP TABLE.|  
|spid|**int**|Session id on the SQL Server instance running the query distribution.||  
|command|**nvarchar(4000)**|Full text of command for this query distribution.|Any valid query or request string.|  
  
 For information about the maximum rows retained by this view, see the Maximum System View Values section in the [Minimum and Maximum Values (SQL Server PDW)](http://msdn.microsoft.com/en-us/5243f018-2713-45e3-9b61-39b2a57401b9) topic.
