regex - Retrieving Certain Strings within a String using Oracle SQL -

hoping can assist next string search using oracle sql 11g r2:

data is:

| cn=axyzapple-au,ou=managed,ou=groups,dc=core,dc=dir,dc=abc,dc=com | cn=31107427,ou=distribution lists,ou=shared mailboxes,dc=core,dc=dir,dc=abc,dc=com | cn=ea90045052,ou=groups,ou=eprofile,dc=core,dc=dir,dc=abc,dc=com | cn=s0901448,ou=distribution lists,ou=shared mailboxes,dc=core,dc=dir,dc=abc,dc=com | cn=00900887,ou=distribution lists,ou=shared mailboxes,dc=core,dc=dir,dc=abc,dc=com | cn=nsmmmm,ou=lrp,ou=groups,dc=core,dc=dir,dc=abc,dc=com | cn=axyzapple-readonly,ou=managed,ou=groups,dc=core,dc=dir,dc=abc,dc=com | cn=wwsww-au,ou=lrp,ou=groups,dc=core,dc=dir,dc=abc,dc=com | cn=alogical_rw,ou=managed,ou=groups,dc=core,dc=dir,dc=abc,dc=com | cn=axyzapple-write,ou=managed,ou=groups,dc=core,dc=dir,dc=abc,dc=com |

from above data, need obtain strings hold string "axyzapple" "ou=managed" sec part of string match.

so based on above, next results after , displayed only:

axyzapple-au axyzapple-readonly axyzapple-write

am using oracle regexp_like/regexp_replace.

you utilize regexp_substr split input info lines , relevant strings, example:

sql> select regexp_substr(line, 'axyzapple[^,]*') subtxt 2 (select regexp_substr(:x, '[^|]*\|', 1, rownum + 1) line 3 dual 4 connect level <= length(:x) - length(replace(:x, '|', ''))) 5 regexp_substr(line || ',', '[^,]*,', 1, 2) = 'ou=managed,' 6 , line '%axyzapple%'; subtxt -------------------------------------------------------------------------------- axyzapple-au axyzapple-readonly axyzapple-write

here's little explanation. have go through query step step.

the inner part of query loop through info (for each |):

sql> select regexp_substr(:x, '[^|]*\|', 1, rownum + 1) line 2 dual 3 connect level <= length(:x) - length(replace(:x, '|', '')); line -------------------------------------------------------------------------------- cn=axyzapple-au,ou=managed,ou=groups,dc=core,dc=dir,dc=abc,dc=com | cn=31107427,ou=distribution lists,ou=shared mailboxes,dc=core,dc=dir,dc=abc,dc= cn=ea90045052,ou=groups,ou=eprofile,dc=core,dc=dir,dc=abc,dc=com | cn=s0901448,ou=distribution lists,ou=shared mailboxes,dc=core,dc=dir,dc=abc,dc= cn=00900887,ou=distribution lists,ou=shared mailboxes,dc=core,dc=dir,dc=abc,dc= cn=nsmmmm,ou=lrp,ou=groups,dc=core,dc=dir,dc=abc,dc=com | cn=axyzapple-readonly,ou=managed,ou=groups,dc=core,dc=dir,dc=abc,dc=com | cn=wwsww-au,ou=lrp,ou=groups,dc=core,dc=dir,dc=abc,dc=com | cn=alogical_rw,ou=managed,ou=groups,dc=core,dc=dir,dc=abc,dc=com | cn=axyzapple-write,ou=managed,ou=groups,dc=core,dc=dir,dc=abc,dc=com |

you loop ou=managed string in sec position:

sql> select regexp_substr(line || ',', '[^,]*,', 1, 2) second_part 2 (select regexp_substr(:x, '[^|]*\|', 1, rownum + 1) line 3 dual 4 connect level <= length(:x) - length(replace(:x, '|', ''))); second_part -------------------------------------------------------------------------------- ou=managed, ou=distribution lists, ou=groups, ou=distribution lists, ou=distribution lists, ou=lrp, ou=managed, ou=lrp, ou=managed, ou=managed,

finally, select relevant part lastly regexp_substr.

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...
