java - Retriving records from database using hibernate -

i have class trade , subclass operation. mapped in database. when do:

trades = session.createquery("from trade").list()

i arraylist of trade records , can access operations trade through trade instance.

however, when do:

trades = session.createquery(" trade trade inner bring together trade.operations operation to_char(operation.datetime, 'yyyymmdd') = to_char(sysdate, 'yyyymmdd') order operation.datetime" ).list();

i array of objects each element contains operation , trade instance.

how retrieve records array of trades (same first option) conditions (same sec option)?

i tried: select trade trade trade inner bring together trade.operations operation to_char(operation.datetime, 'yyyymmdd') = to_char(sysdate, 'yyyymmdd') order operation.datetime

it worked, javatestcase. however, when loop trade.operations, trades contain operations today, operations trade, if it's operation day. doesn't satisfy condition.

any clue?

thanks in advance!!

trade.operations contain operations trade. hibernate won't give trades partial initialized kid collection because breaks alter tracking , leads many confusions downwards road. best hibernate can give pairs of trades , matching operations. create class containing properties need trade , matching operation , utilize aliastobeantransformer.

java hibernate

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
