python.library.sqlite3#sqlite3.Cursor.fetchall
fetchmany(size=cursor.arraysize) Fetches the next set of rows of a query result, returning a list. An empty list is returned when no more rows are available. The number of rows to fetch per call is specified by the size parameter. If it is not given, the cursor’s arraysize determines the number of rows to be fetched....
python.library.sqlite3#sqlite3.Cursor.fetchmany
fetchone() Fetches the next row of a query result set, returning a single sequence, or None when no more data is available.
python.library.sqlite3#sqlite3.Cursor.fetchone
lastrowid This read-only attribute provides the rowid of the last modified row. It is only set if you issued an INSERT or a REPLACE statement using the execute() method. For operations other than INSERT or REPLACE or when executemany() is called, lastrowid is set to None. If the INSERT or REPLACE statement failed to ...
python.library.sqlite3#sqlite3.Cursor.lastrowid
rowcount Although the Cursor class of the sqlite3 module implements this attribute, the database engine’s own support for the determination of “rows affected”/”rows selected” is quirky. For executemany() statements, the number of modifications are summed up into rowcount. As required by the Python DB API Spec, the ro...
python.library.sqlite3#sqlite3.Cursor.rowcount
exception sqlite3.DatabaseError Exception raised for errors that are related to the database.
python.library.sqlite3#sqlite3.DatabaseError
