# getByte Method (java.lang.String) (SQLServerResultSet)
[!INCLUDE[Driver_JDBC_Download](../../../includes/driver_jdbc_download.md)]

  Retrieves the value of the designated column name in the current row of this [SQLServerResultSet](../../../connect/jdbc/reference/sqlserverresultset-class.md) object as a **byte** in the Java programming language.  
  
## Syntax  
  
```  
  
public byte getByte(java.lang.String columnName)  
```  
  
#### Parameters  
 *columnName*  
  
 A **String** that contains the column name.  
  
## Return Value  
 A **byte** value.  
  
## Exceptions  
 [SQLServerException](../../../connect/jdbc/reference/sqlserverexception-class.md)  
  
## Remarks  
 This getByte method is specified by the getByte method in the java.sql.ResultSet interface.  
  
 This method is supported only on [!INCLUDE[ssNoVersion](../../../includes/ssnoversion-md.md)] data types that can safely return a byte value, such as tinyint and bit. All other data types will cause an exception to be thrown.
