Re: [RCU] [Q] mysql.update.sql Can't DROP 'idx'; check that column/key exist

A bit confusing, because, unless I have misinterpreted the results below, there are indices on the columns so the /drop index/ should work:-

The rest of the upgrade script probably didn't run, to be honest I have no idea how it works as I have not done one for a long time. Perhaps you are able to run it again, if so either remove that 'DROP INDEX' from the query that gets run or create the index so it is able to drop it.

Hi,

As long as line 7 is actually a 'DROP INDEX' you should be fine, it just means the index it was doing to remove wasn't there.

With mySQL, when you run 'describe messages' it will only show the columns from the table, not any indexes. If you want to show indexes, use 'show index in messages'.

Hi,

After a RC upgrade (.5.4 -> 0.6), can one blindly run the

mysql.update.sql, or should I adjust it accordingly to the release I am upgrading from? I ask as I tried and it complained:-

root@peon /www/roundcube/SQL # mysql*-p roundcubemail < mysql.update.sql * Enter password: ERROR 1091 (42000) at line 7: Can't DROP 'idx'; check that column/key exist

Entry in the mysql.update.sql reads:

ALTER TABLE `messages`
  DROP INDEX `idx`,
  DROP INDEX `uid`;

Does this mean that it ran successfully or, it bombed out when it tried to drop an inexistent index? If the later, then I can comment out this portion and run again.

Although, there is now an index, so I think this ran ;)

The words column is not there. I think the update script failed, because its in it: ALTER TABLE contacts ADD words TEXT NULL AFTER vcard;

roundcube: MDB2 Error: no such field (-19): _doQuery: [Error message: Could not execute statement]#012[Last executed query: INSERT INTO contacts (user_id, changed, del, vcard, name, email, firstname, surname, words) VALUES (5, now(), 0, 'BEGIN:VCARD\r\nVERSION:3.0\r\nN:test;test;;;\r\nFN:test test\r\nEMAIL;type=INTERNET;type=HOME:sas@mailcatch.com\r\nEND:VCARD', 'test test', 'sas@mailcatch.com', 'test', 'test', ' test sas@mailcatch.com')]#012[Native code: 1054]#012[Native message: Unknown column 'words' in 'field list'
