sql - MySQL special INSERT/SELECT statement required for updating while copying rows in a table -

table a: column type, column type_id, column_owner, column_data1, column_data2, , on ----------- -------------- ------------ ------------ ------------ 'type a' 43 'owner sally' 'dfawerfd' 'yiyiyitit' 'type b' 51 'owner sally' 'hufvgdfd' 'weysdgjed' 'type c' 77 'owner sally' '3fdfsetr' '4tgfgert4' table b: column type, column type_id, column_owner ----------- -------------- ------------ 'type a' 43 'owner sally' 'type b' 51 'owner sally' 'type c' 77 'owner sally' 'type a' 100 'owner harry' 'type b' 111 'owner harry' 'type c' 150 'owner harry'

help needed develop 1 magic sql statement insert new rows in table copies of rows in table a.column_owner = 'owner sally'; , each new record inserted, column values should copied a.column_owner should set 'owner harry' , a.type_id should set b.type_id a.type == b.type , b.column_owner == 'owner harry'.

so, new table like:

table a: column type, column type_id, column_owner, column_data1, column_data2, , on ----------- -------------- ------------ ------------ ------------ 'type a' 43 'owner sally' 'dfawerfd' 'yiyiyitit' 'type b' 51 'owner sally' 'hufvgdfd' 'weysdgjed' 'type c' 77 'owner sally' '3fdfsetr' '4tgfgert4' 'type a' 100 'owner harry' 'dfawerfd' 'yiyiyitit' 'type b' 111 'owner harry' 'hufvgdfd' 'weysdgjed' 'type c' 150 'owner harry' '3fdfsetr' '4tgfgert4'

i have 13,000+ records in table copy/update, 1 sql command if possible job appreciated.

i forwards community's help here, give thanks you!

there no way upfront know if satisfies 13.000 records illustration you've given, next statement trick.

the gist of query to

join both tables on column_type selectthe appropriate fields each table insert records in tablea

sql statement

insert tablea select a.column_type , b.column_type_id , b.column_owner , a.column_data1 , a.column_data2 tablea inner bring together tableb b on b.column_type = a.column_type b.column_owner = 'owner harry'

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...
