pwtools.sql.SQLiteDB.attach_column

SQLiteDB.attach_column(col, values, sqltype=None, table=None, **kwds)[source]

Attach (add) a new column named col of sqltype and fill it with values. With overwrite=True, allow writing into existing columns, i.e. behave like fill_column().

This is a short-cut method which essentially does add_column(...); fill_column(...)

Parameters:

  • col (str) – Column name.

  • values (sequence) – Values to be inserted.

  • sqltype (str, optional) – sqlite type of values in values, obtained from values[0] if None

  • table (str, optional)

  • **kwds – additional keywords passed to fill_column(), default: start=1, extend=True, overwrite=False
