MySQL Bugs: #84346: Generated Columns not supported in MySQLWorkbench Community

Bug #84346	Generated Columns not supported in MySQLWorkbench Community
Submitted:	27 Dec 2016 11:35	Modified:	27 Dec 2016 23:53
Reporter:	Andre Rippstein	Email Updates:
Status:	Not a Bug	Impact on me:	None
Category:	MySQL Workbench: SQL Editor	Severity:	S1 (Critical)
Version:	6.3.8. build 1228 CE	OS:	Any
Assigned to:		CPU Architecture:	Any
Tags:	GENERATED_ALWAYS

Description:
MySQLWorkbench Community Edition does not allow to use 'GENERATED ALWAYS' syntax while creating a column in a table. The response is:

Error Code: 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 'GENERATED ALWAYS AS (concat(first_name,' ',last_name)),     email VARCHAR(100) N' at line 5	0.012 sec

I found a similar bug (closed) at http://bugs.mysql.com/bug.php?id=77837 
According this bug the problem has been fixed in version 6.3.6. Unfortunately the problem is not fixed in the current community edition build 6.3.8. build 1228 CE
Can you please check if this bug has been fixed for the community edition of the product also?

How to repeat:
CREATE TABLE contacts (
    id INT AUTO_INCREMENT PRIMARY KEY,
    first_name VARCHAR(50) NOT NULL,
    last_name VARCHAR(50) NOT NULL,
    fullname varchar(101) GENERATED ALWAYS AS (concat(first_name,' ',last_name)),
    email VARCHAR(100) NOT NULL
);

Server Version: 5.6.33 MySQL Community Server (GPL)
Compiled for: linux-glibc2.5   (x86_64)

Thank you for the bug report. Yes not supported for your server version:

https://dev.mysql.com/doc/refman/5.7/en/create-table-generated-columns.html

"As of MySQL 5.7.6, CREATE TABLE supports the specification of generated columns. Values of a generated column are computed from an expression included in the column definition. "
