# SQLGetDescRec
  This topic discusses SQLGetDescRec functionality that is specific to [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] Native Client.  
  
## SQLGetDescRec and Table-Valued Parameters  
 SQLGetDescRec can be used to get values for attributes of table-valued parameters and table-valued parameter columns. The *RecNumber* parameter of SQLGetDescRec corresponds to the *ParameterNumber* parameter of SQLBindParameter.  
  
 Table-valued parameter columns are only available when the descriptor header field SQL_SOPT_SS_PARAM_FOCUS is set to the ordinal of a record that has SQL_DESC_TYPE set to SQL_SS_TABLE. For more information about SQL_SOPT_SS_PARAM_FOCUS about, see [SQLSetStmtAttr](sqlsetstmtattr.md).  
  
 SQLGetDescRec returns the following data:  
  
|Parameter|Table-valued parameter|Table-valued parameter columns and other parameters|  
|---------------|-----------------------------|----------------------------------------------------------|  
|*Name*|The formal parameter name for a stored procedure call; otherwise, a 0 length string.|The table-valued parameter column name.|  
|*TypePtr*|SQL_DESC_TYPE. For table-vaued parameters, this is SQL_SS_TABLE.|SQL_DESC_TYPE|  
|*SubTypePtr*|Undefined|SQL_DESC_DATETIME_INTERVAL_CODE (For records of type SQL_DATETIME or SQL_INTERVAL.)|  
|*LengthPtr*|0|SQL_DESC_OCTET_LENGTH|  
|*PrecisionPtr*|0|SQL_DESC_PRECISION|  
|*ScalePtr*|0|SQL_DESC_SCALE|  
|*NullablePtr*|1|SQL_DESC_NULLABLE|  
  
 For more information about table-valued parameters, see [Table-Valued Parameters (ODBC)](../native-client-odbc-table-valued-parameters/table-valued-parameters-odbc.md).  
  
## SQLGetDescRec Support for Enhanced Date and Time Features  
 The values returned for date/time types are as follows:  
  
||*TypePtr*|*SubTypePtr*|*LengthPtr*|*PrecisionPtr*|*ScalePtr*|  
|-|---------------|------------------|-----------------|--------------------|----------------|  
|datetime|SQL_DATETIME|SQL_CODE_TIMESTAMP|4|3|3|  
|smalldatetime|SQL_DATETIME|SQL_CODE_TIMESTAMP|8|0|0|  
|date|SQL_DATETIME|SQL_CODE_DATE|6|0|0|  
|time|SQL_SS_TIME2|0|10|0..7|0..7|  
|datetime2|SQL_DATETIME|SQL_CODE_TIMESTAMP|16|0..7|0..7|  
|datetimeoffset|SQL_SS_TIMESTAMPOFFSET|0|20|0..7|0..7|  
  
 For more information, see [Date and Time Improvements (ODBC)](../native-client-odbc-date-time/date-and-time-improvements-odbc.md).  
  
## SQLGetDescRec Support for Large CLR UDTs  
 `SQLGetDescRec` supports large CLR user-defined types (UDTs). For more information, see [Large CLR User-Defined Types (ODBC)](../native-client/odbc/large-clr-user-defined-types-odbc.md).
