As am I preparing my master degree thesis on zabbix, I downloaded zabbix 1.9.4 alpha release of 2.0 for installation and started to do some tests. At the installation I found a bug in the script that is used to create the database for zabbix.
I am working on Solaris Sparc 10 (SunOS AMM-SUN6-2-1 5.10 Generic_137137-09 sun4u sparc SUNW,SPARC-Enterprise), and use mysql 5.0.67 (mysql Ver 14.12 Distrib 5.0.67, for sun-solaris2.10 (sparc) using EditLine wrapper ). The bug is found in the database schema file : create/schema/mysql.sql around the line to create the TABLE NAME expression. Mysql server gives error in the line to create the column. I thought that it may be that the name you used for the colum is a key word for mysql itself then it needs to be escaped properly to be accepted as a column name.

create/schema/mysql.sql

The bug for solaris in bold
CREATE TABLE expressions (
expressionid bigint unsigned NOT NULL,
regexpid bigint unsigned NOT NULL,
expression varchar(255) DEFAULT '' NOT NULL,
expression_type integer DEFAULT '0' NOT NULL,
exp_delimiter varchar(1) DEFAULT '' NOT NULL, --this is the bug
case_sensitive integer DEFAULT '0' NOT NULL,
PRIMARY KEY (expressionid) ) ENGINE=InnoDB;

Here is the fix to that bug for Solaris SPARC 10:

CREATE TABLE expressions (
expressionid bigint unsigned NOT NULL,
regexpid bigint unsigned NOT NULL,
expression varchar(255) DEFAULT '' NOT NULL ,
expression_type integer DEFAULT '0' NOT NULL,
`exp_delimiter` VARCHAR(1) DEFAULT '' NOT NULL, --this is the fix by escaping the column with quotes `exp_delimiter`
case_sensitive integer DEFAULT '0' NOT NULL,
PRIMARY KEY (expressionid) ) ENGINE=InnoDB;
