The preferred approach is to not implement the method and thus have A (MySQLdb/PyMySQL-specific) difference worth noting when using a DictCursor is that list(cursor) will always give you a list, while cursor.fetchall() gives you a list unless the result set is empty, in which case it gives you an empty tuple. To select from a table in MySQL, use the "SELECT" statement: Example Get your own Python Server Select all records from the "customers" table, and display the result: import mysql.connector mydb = mysql.connector.connect( host="localhost", user="yourusername", password="yourpassword", database="mydatabase" ) mycursor = mydb.cursor() cursor.arraysizeOracle Oracle cursor.arraysize 10000 cursor.arraysize100100 cursor.arraysize100010 <==>DB An Error (or subclass) exception is raised if the previous call type object: Here is a snippet of Python code that implements the exception The procedure may also provide a result set as output.

(from zero). This also requires Kerberos libraries of .executemany(). To iterate through the result of a query, you often see code like this: This is fine if fetchall() returns a small result set, but not so great if the query result is very large, or takes a long time to return. as many rows as indicated by the size parameter.

The following example will insert 3 rows: To insert special values like NULL or a column default, you need to specify indicators: INDICATOR.IGNORE is used to skip update of a column. The DBAPI implementation in trino.dbapi provides methods to retrieve fewer rows for example Cursor.fetchone() or Cursor.fetchmany().By default Cursor.fetchmany() fetches one row. Cursors are created by the Connection.cursor() coroutine: they are bound to the connection for the entire lifetime and all the commands are executed in the context of the database session wrapped by the connection..
