pwtools.sql.SQLiteDB.fill_column

SQLiteDB.fill_column(col, values, start=1, extend=True, overwrite=False, table=None)[source]

Fill existing column col with values from values, starting from rowid start. “rowid” is a special sqlite column which is always present and which numbers all rows.

The column must already exist. To add a new column and fill it, see attach_column().

Parameters:

  • col (str) – Column name.

  • values (sequence) – Values to be inserted.

  • start (int) – sqlite rowid value to start at (first row: start=1)

  • extend (bool) – If extend=True and len(values) extends the last row, then continue to add values. All other column entries will be NULL. If False, then we silently stop inserting at the last row.

  • overwrite (bool) – Whether to overwrite entries which are not NULL (None in Python).

  • table (str, optional) –
