I have 2 MySQL dump files. I want to find the table data difference between 2 tables.
run mysqldump with “–skip-opt” to get the 2 dumps files i.e:
mysqldump --skip-opt -u $MY_USER -p$MY_PASS mydb1 > /tmp/dump1.sql mysqldump --skip-opt -u $MY_USER -p$MY_PASS mydb2 > /tmp/dump2.sql
compare using these diff options:
diff -y --suppress-common-lines /tmp/dump1 /tmp/dump2
Maybe you can give a tool called mysqldiff a go, I haven’t tried it myself yet but it’s been on my list for a while.
In order to compare 2 mysql diffs they need to be done in a certain manner, so that the order is in a defined way and non relevant data is omitted.
This was at one point not totally possible with
mysqldump, I am not sure if this has changed in the meantime.
If you want to compare to an old dump, like in the question, you could first create a temporary database from the dump and then start there.
