To execute the SQLite3 statements, you should establish a connection at first and then create an object of the cursor using the connection object as follows: These examples are extracted from open source projects. It is also used when a cursor is used as an iterator. See Cursor in the specification. Search cursors can be iterated using a for loop. Search cursors also support with statements to reset iteration and aid in removal of locks. These examples are extracted from open source projects. An empty list is returned when no rows are available. This is a read only property which returns the list containing the description of columns in a result-set. You can create Cursor object using the cursor() method of the Connection object/class. To execute SQLite statements in Python, you need a cursor object. First, establish a connection to the Oracle Database using the cx_Oracle.connect () method. Cursor.execute. This returns the number of rows returned/updated in case of SELECT and UPDATE operations. The SQL statement may be parameterized (i.e., placeholders instead of SQL literals). Um das Modul verwenden zu können, müssen Sie zuerst ein Connection-Objekt erstellen, das die Datenbank darstellt. This method is similar to the fetchone() but, it retrieves the next set of rows in the result set of a query, instead of a single row. Using the methods of it you can execute SQL statements, fetch data from the result sets, call procedures. Cursor.fetchmany ... was designed for use with PL/SQL in/out variables where the length or type cannot be determined automatically from the Python object passed in or for use in input and output type handlers defined on cursors or connections.
