 Description   

Trying to install Zabbix 3.2.6, using MySQL 8.0.2 I got this message (among many similar ones):

   ...
    26:20170801:200803.540 completed 86% of database upgrade
    26:20170801:200804.646 completed 87% of database upgrade
    26:20170801:200805.131 completed 88% of database upgrade
    26:20170801:200805.935 [Z3005] query failed: [1064] You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'groups

    26:20170801:200805.936 database upgrade failed

I checked, and as per the official MySQL documentation ( https://dev.mysql.com/doc/refman/8.0/en/keywords.html ), "groups" is added as a reserved word since version 8.0.2.

Also, as the schema.sql is properly backticked - there is a chance this requires a considerable refactoring effort to fix...

  • Also affects 3.2.7
  • Verified that the problem does not appear when using MySQL 5.7.19

MySQL 8.0.2 not released yet. Proposed to postpone the issue until MySQL 8 official release.

Comment by Mikhail Grigorev [ 2018 Apr 23 ]

Hi

MySQL 8.0.11 is released in 19.04.2018

When will Zabbix developers be able to add support for MySQL 8.0?

Can I expect this in the next release?

Comment by Mikhail Grigorev [ 2018 Apr 23 ]

table groups to grp ?

or

table groups to groups_users ?

Comment by Tomasz Kłoczko [ 2018 May 02 ]

Can someone with MariaDB devel env test patch attached in ZBX-14311? Just tested my patch on MySQL 5.7.22 and does not causes compile issues. Only after about two days of using zabbix 3.4.8 binaries which have been using MySQL 8.0.11 client ABI I've decided to upgrade MySQL server as well and of course I the same issues with group and function keywords.  So this would be about zabbix and MySQL 8.0.x client API compliance. With ZBX-14311 patch zabbix will be MySQL 8.0.11 client API compliant

Second thing: if current zabbix is not ready to be used with MySQL 8.0.x server maybe it would be good to add a check during db connection initialization and if 8.0.x server found just print error message and exit with error message?

Hello kloczek if you are interested you can have a look at development branch:
svn://svn.zabbix.com/branches/dev/ZBX-12451

my_bool is used as per MySQL documentation:
https://dev.mysql.com/doc/refman/5.7/en/c-api-auto-reconnect.html

If we are to use _Bool then following warnings appears

main.c: In function ‘main’:
main.c:3:2: warning: ISO C90 does not support boolean types [-Wpedantic]

Implemented in:

(1) Looks like these changes have not made it into https://www.zabbix.com/documentation/4.0/manual/installation/upgrade_notes_400 .

martins-v RESOLVED in the upgrade notes for 4.0.

sasha In this section, changes in the database should be mentioned. The 'groups' table has been renamed to 'hstgrp', the 'function' field in the 'functions' table - to 'name'

REOPENED

martins-v Thanks, updated the upgrade note entry. RESOLVED

sasha It seems we use double quotes instead of single quotes. Or am I wrong?

martins-v There isn't really a convention about it, because it is not that often we have to document database changes in public documentation. I try to use single quotes as much as possible in dokuwiki, because they are not smartly converted by dokuwiki and I don't have to escape the smart conversion. To me single quotes also seem more "technical" than double quotes.

sasha Thanks for explanation! CLOSED
