Only replace string in sql when not adjacent to other characters -

i'm using mssql 2008 replace values in columns. current query is:

update table set name = replace(name, 'old', 'new')

i know if possible replace 'old' 'new' when 'old' not adjacent other characters. is: when occurs 'old' ensure e.g. 'bold' not become 'bnew'

currently i'm retrieving results via jdbc, splitting string @ delimiter (,) , checking if string equals'old'. if want replace 'new'. takes long time retrieve results , send them back, if possible sending sql-statement containg 'old' & 'new' great!

records should replaced:

'old , blabla blabla, bla' 'blabla, old, blabla' 'blabla, bla old, blabla' 'blabla, blabla, old' 'blabla, bla old bla'

records shouldn't replaced:

'blaold, blabla' 'blabla, oldbla'

use spaces in clauses.

update [yourtable] set name = replace(name, ' old ', 'new') name = ' old '

sql replace

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...
