MySQL Connector/Python Developer Guide  /  ...  /  MySQLConnection.cmd_query_iter() Method

10.2.14 MySQLConnection.cmd_query_iter() Method

Syntax:

cnx.cmd_query_iter(statement)

Similar to the cmd_query() method, but returns a generator object to iterate through results. Use cmd_query_iter() when sending multiple statements, and separate the statements with semicolons.

The following example shows how to iterate through the results after sending multiple statements:

statement = 'SELECT 1; INSERT INTO t1 VALUES (); SELECT 2'
for result in cnx.cmd_query_iter(statement):
  if 'columns' in result:
    columns = result['columns']
    rows = cnx.get_rows()
  else:
    # do something useful with INSERT result

Returns a generator object.
