    Cursor Objects — PyMySQL 0.7.2 documentation https://pymysql.readthedocs.io/en/latest/modules/cursors.html#pymysql.cursors.Cursor.executemany

    executemany(queryargs)

    Run several data against one query

    Parameters:
    • query – query to execute on server
    • args – Sequence of sequences or mappings. It is used as parameter.
    Returns:

    Number of rows affected, if any.

    This method improves performance on multiple-row INSERT and REPLACE. Otherwise it is equivalent to looping over args with execute().


    sql_a_executemany = 'INSERT INTO answer ({}) VALUES (%s,%s,%s)'.format(field_a_insert)

    l = []
    for k in d['a']:
    qid, content, created = dbid, d['a'][k], tm
    l.append((qid, content, created))
    sql_executemany = {}
    sql_executemany['sql'], sql_executemany['args'] = sql_a_executemany, l
    mysql_write(sql_executemany, executemany=True)


    if executemany:
    cursor.executemany(sql['sql'], sql['args'])
    else:
    cursor.execute(sql)
