Data Conversion

sapdbapi implements the recommended functions to convert Python values into the SAP DB internal format.
  • Date (year, month, day)
  • Time (hour, minute, second)
  • Timestamp (year, month, day, hour, minute, second, micros = 0)
  • DateFromTicks (ticks)
  • TimeFromTicks (ticks)
  • TimestampFromTicks (ticks)


Furthermore, sapdbapi exports callable objects to translate SAP DB internal values to Python values:
  • dateTuple: Returns the tuple (year, month, day)
  • timeTuple: Returns the tuple (hour, minute, second)
  • timestampTuple: Returns a tuple in the same format as time.localtime ()
  • dateVal: Returns the no. of seconds since epoch
  • timeVal: Returns the no. of seconds since epoch
  • timestampVal: Returns the no. of seconds since epoch
  • DateFormat (formatString): Returns date formatted by using time.strftime
  • TimeFormat (formatString): Returns time formatted by time.strftime
  • TimestampFormat (formatString): Returns timestamp formatted by time.strftime

The following callable objects can be registered with a Cursor object or with a Connection object. Please note that only newly created objects will use this translation.

  • Registering with a Cursor by position:
    cursor.setTranslation ([
            None,
            sapdbapi.dateTuple,
            sapdbapi.DateFormat('%Y-%m-%d')])
  • Registering with a Cursor by type:
    cursor.setTypeTranslation ({
            'Date': sapdbapi.dateTuple,
            'Time': sapdbapi.timeTuple,
            'Fixed': str})
  • Registering with a Connection by type:
    connection.setTypeTranslation ({
            'Date': sapdbapi.dateTuple,
            'Time': sapdbapi.timeTuple,
            'Fixed': str})

LONG Handling

Output: LONG columns are returned as instances of SapDB_LongReader. This class implements the read () method similar to a file stream.

Input: LONG parameters can be written by using a string or by using a callable object similar to file.read.
