# sys.partition_parameters (Transact-SQL)
[!INCLUDE[tsql-appliesto-ss2008-asdb-asdw-pdw-_md](../../includes/tsql-appliesto-ss2008-asdb-asdw-pdw-md.md)]

  Contains a row for each parameter of a partition function.  
  
|Column name|Data type|Description|  
|-----------------|---------------|-----------------|  
|**function_id**|**int**|ID of the partition function to which this parameter belongs.|  
|**parameter_id**|**int**|ID of the parameter. Is unique within the partition function, beginning with 1.|  
|**system_type_id**|**tinyint**|ID of the system type of the parameter. Corresponds to the **system_type_id** column of the **sys.types** catalog view.|  
|**max_length**|**smallint**|Maximum length of the parameter in bytes.|  
|**precision**|**tinyint**|Precision of the parameter if numeric-based; otherwise, 0.|  
|**scale**|**tinyint**|Scale of the parameter if numeric-based; otherwise, 0.|  
|**collation_name**|**sysname**|Name of the collation of the parameter if character-based; otherwise, NULL.|  
|**user_type_id**|**int**|ID of the type. Is unique within the database. For system data types, **user_type_id** = **system_type_id**.|
