10.5.21 MySQLCursor.with_rows Property

Syntax:

Press CTRL+C to copy
 
boolean = cursor.with_rows

This read-only property returns True or False to indicate whether the most recently executed operation could have produced rows.

The with_rows property is useful when it is necessary to determine whether a statement produces a result set and you need to fetch rows. The following example retrieves the rows returned by the SELECT statements, but reports only the affected-rows value for the UPDATE statement:

Press CTRL+C to copy
 
import mysql.connector

cnx = mysql.connector.connect(user='scott', database='test')
cursor = cnx.cursor()
operation = 'SELECT 1; UPDATE t1 SET c1 = 2; SELECT 2'
for result in cursor.execute(operation):
  if result.with_rows:
    result.fetchall()
  else:
    print("Number of affected rows: {}".format(result.rowcount))
