MySQL error 1064 syntax but everything seems fine

Question

Im using xampp control panel and from there i start the process for apache and mysql. Then i go to mysql workbench and server status seems to be ok, here is some info

Host: Windows-PC
Socket: C:/xampp/mysql/mysql.sock
Port: 3306
Version 10.1.31-MariaDB mariadb.org binary distribution
Compiled For: Win32(32)
Configuratin File: unknown

Then everytime when i try to add the foreign key for my dummy schema like:

 ALTER TABLE `puppies`.`animals` 
 ADD INDEX `Breed_idx` (`BreedID` ASC) VISIBLE;
 ;
 ALTER TABLE `puppies`.`animals` 
 ADD CONSTRAINT `Breed`
 FOREIGN KEY (`BreedID`)
 REFERENCES `puppies`.`breeds` (`Breed`)
 ON DELETE NO ACTION
 ON UPDATE NO ACTION;

I get the following error

 ERROR 1064: You have an error in your SQL syntax; check the manual that 
 corresponds to your MariaDB server version for the right syntax to use near 
 '' at line 2
 SQL Statement:
 ALTER TABLE `puppies`.`animals` 
 ADD INDEX `Breed_idx` (`BreedID` ASC) VISIBLE

So what can i do so that xampp will start using mysql syntax over mariaDb?

Or if im wrong in my understanding of the problem, then what should i do so that i dont have to face this kind of issues again when using xampp?

Answer 1

Problem is the word VISIBLE, remove it and it will work. Index are visible by default.

Your question: "If i remove VISIBLE it works just fine, so why did mysql workbench decided to add visible?"

My answer: The option to mark index invisible is not yet implemented in MariaDB (afaik!).

Update:

The syntax for MariaDB is different, please see this reference: https://jira.mariadb.org/browse/MDEV-7317

Answer 2

Just to add to those who are using Maria DB with MySQL Workbench, you don't need to install mysql. You can just change 'Default Target MySQL Version' from Preferences to 5.7 or 5.6, and the VISIBLE keyword will be removed by workbench.

Answer 3

I am using MySQL Workbench and have same problem. Change in the Preferences but it did not work.

Solution: If you export forward-engineer the model you need to change the configuration on another place.

1. Go to Model > Model Options
2. Inside the Model Options, go to MySQL
3. Then change the "Target MySQL Version" to 5.6
