Import of SQL Dump - bash

Question

From the below extract of data I am trying to view out only the items in bold, is there a way to do this? The specific section of the file of this is important which is why the 'into .db. values' is important - also assume I do NOT know the actual value of these
grep "INTO .db. VALUES" ./anikokiss_mysql4.sql
INSERT INTO db VALUES ('localhost','blog','yscr_bbYcqN','Y','Y','Y','Y','Y','N','N','N','N','N'),('localhost','blog1','yscr_bbS4kf','Y','Y','Y','Y','Y','N','N','N','N','N'),('localhost','blog','yscr_bbhrSZ','Y','Y','Y','Y','Y','N','N','N','N','N'),('localhost','blog','yscr_bbBl0C','Y','Y','Y','Y','Y','N','N','N','N','N'),('localhost','blog','yscr_bbrsKX','Y','Y','Y','Y','Y','N','N','N','N','N');
Result of
cut -d',' -f2 <(awk '/.*INTO .?db.? VALUES.*/,/.*;/{if (NR > 2) nr[NR]}; NR in nr' ./anikokiss_mysql4.sql)
Is
'blog'
As such it appears to only pick the first batch of command seperated values and ignore those after
Similarly with grep command
grep "INTO .db. VALUES" ./anikokiss_mysql4.sql | cut -d "'" -f4
We get the result
blog
When I was updating DB names
find . -name '*.sql' -exec sed -i "s/\\(CREATE DATABASE [^\`]*\`\\)/\\1${cpuser}_/" {} +
Current output
[root#uk01 public_html]# grep -Pzo '(?s)INTO .?db.? VALUES[^(]\K[^;]*' aniko.sql | grep -Pao '\(([^,]*,){2}\K[^,]*' | sed -e 's/^/test_/'
test_'yscr_bbYcqN'
test_'yscr_bbS4kf'
test_'yscr_bbhrSZ'
test_'yscr_bbBl0C'
test_'yscr_bbrsKX'

This uses grep to achieve what you want:
grep -Pzo '(?s)INTO .?db.? VALUES[^(]\K[^;]*' ./anikokiss_mysql4.sql | grep -Pao '\([^,]*,\K[^,]*'
First I use grep to get everything after INTO db VALUES. Then, pass the output of that to another instance of grep which cuts it after the first ,.
To change what column to get you can just keep repeating the look behind in the last grep {N}:
# This gets first column
grep -Pzo '(?s)INTO .?db.? VALUES[^(]\K[^;]*' file | grep -Pao '\(([^,]*,){0}\K[^,]*'
# This gets fourth column
grep -Pzo '(?s)INTO .?db.? VALUES[^(]\K[^;]*' file | grep -Pao '\(([^,]*,){3}\K[^,]*'
Will get the fourth column,
