Darlington: It’s a bad idea to use the 5.6 version of mysqldump to dump a 5.0 server
Toms: I’m not, I’m using mysqldump on a 5.6 server, connecting to 5.0, then importing to 5.6
Vanmatre: Well, nothing wrong with the Niedzwiedzki you have shown there
Jokela: So you’re saying mysql hates me, I get it!
Seeds: But you still shouldn’t import a mysql.user from 5.0 into 5.6; the format has changed
Million: I’m writing a script to convert mysql.user from 5.6 to 5.6 for a client/blog post
Deason: Ashleyhindle: use pt-show-grants
Matzek: Thanks Deason I’ll look, never heard of that before
Deason: Ashleyhindle: your result will be DCL rather than DML, which is portable
Orta: I’ve never seen BN before
Rhoe: Thanks Deason/snoyes, I’ll gander!
Deason: Ashleyhindle: also, mysql_upgrade
Propst: If you want that bit to make something you can import, append this: sed “s/$/;/”
Petch: Would mysql_upgrade work from 5.0 to 5.6?
Adamsky: And I can’t upgrade 5.0 to 5.6, 5.6 is a separate server
Taschereau: You can import a 5.0 version of mysql.user into a 5.6 server, then run mysql_upgrade and it will fix the missing columns
Bernsen: But that supposed that you have the dump dropping and recreating the table in the old format, which yours doesn’t
Kibbler: So instead you’re likely to get something about wrong number of columns, unless you’re using complete inserts
Tunks: Yea, that’s what I tried to do, got wrong columns, found the 6 column difference then using sed to modify the dump to import
Elfenbein: But show grants for is so much better
Venezia: The grant/revoke system is one of the most hated things about mysql
Venezia: While it’ll work here for a one-off, if you’re writing a tool, make it smart about columns and use the tables + flush
Plotts: This is only a one off, but glad I learnt something new
Deason: Dave_s: i’m not sure.
Deason: Dave_s: http://pastie.org/private/atdvxvnoxofwfhe5ubwywa
Deason: Dave_s: key_len increased in explain but index_length in table status and values in INNODB_BUFFER_PAGE did not. i am pretty sure this is free
Deason: As i originally guessed, based on that link i sent
Hohl: How could I modify this query so that the ORDER BY happens before the GROUP BY? http://pastebin.com/XTMswLYb
Decoux: Daverich: ORDER BY is always done after GROUP BY.
Hewatt: So are two queries needed then?
Gubala: Is there some webpage that has a good beginner breakdown of the different index types?
Strathman: TheQuack45: https://www.youtube.com/watch?v=AVNjqgf7zNw
Hesterman: Gidwani: I’m trying to understand which I should be using for my current setup INDEX or PRIMARY and how they work in general but I’ll see if this video wroks
Huffmaster: I think its covered there.
Miramontes: Danblack: I’ll take a look, thanks
Strathman: As soon as I write queries in something that’s not MySQL I forgot how awesome GROUP_CONCAT is
Deason: Strathman: and then you use GROUP_CONCAT and forget about max len
Strathman: The SQL server solution to mimic group_concat is especially hilarious: http://stackoverflow.com/questions/17591490/how-to-make-a-query-with-group-concat-in-sql-server
Deason: Strathman: did you try STUFF some linked solution in a duplicate question
