问题
I get the following error from my forward engineered database:
Error Code: 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 ' CONSTRAINT fk_Employees_EmployeeTitle1 FOREIGN KEY (`EmployeeTitle_EmpT' at line 9
The code looks good to me and I have no idea where to go from here to make it work. The code is as follows:

回答1:
The error is caused because of incompatibility between MySQL and MariaDB.
This script is apparently for MySQL, but it's run on MariaDB. Even though MariaDB was originally 100% compatible with MySQL both databases have now diverged. Many people consider MariaDB more advanced now, but that fact is they now have small/big differences here and there.
In this case, when creating an index, the keyword VISIBLE is not supported by MariaDB. Instead of using:
CREATE TABLE IF NOT EXISTS `A2Lewis`.`Employees` (
`empID` INT NOT NULL,
`empFirst` VARCHAR(45) NULL,
`empLast` VARCHAR(45) NULL,
`empWage` DECIMAL(4,2) NULL,
`empPhone` CHAR(10) NULL,
`EmployeeTitle_EmpTitleID` INT NOT NULL,
PRIMARY KEY (`empID`),
INDEX `fk_Employees_EmployeeTitle1_idx` (`EmployeeTitle_EmpTitleID` ASC) VISIBLE,
CONSTRAINT `fk_Employees_EmployeeTitle1`
FOREIGN KEY (`EmployeeTitle_EmpTitleID`)
REFERENCES `A2Lewis`.`EmployeeTitle` (`EmpTitleID`)
ON DELETE NO ACTION
ON UPDATE NO ACTION)
ENGINE = InnoDB;
Use:
CREATE TABLE IF NOT EXISTS `A2Lewis`.`Employees` (
`empID` INT NOT NULL,
`empFirst` VARCHAR(45) NULL,
`empLast` VARCHAR(45) NULL,
`empWage` DECIMAL(4,2) NULL,
`empPhone` CHAR(10) NULL,
`EmployeeTitle_EmpTitleID` INT NOT NULL,
PRIMARY KEY (`empID`),
INDEX `fk_Employees_EmployeeTitle1_idx` (`EmployeeTitle_EmpTitleID` ASC),
CONSTRAINT `fk_Employees_EmployeeTitle1`
FOREIGN KEY (`EmployeeTitle_EmpTitleID`)
REFERENCES `A2Lewis`.`EmployeeTitle` (`EmpTitleID`)
ON DELETE NO ACTION
ON UPDATE NO ACTION)
ENGINE = InnoDB;
The second query (for MariaDB) does not require VISIBLE since indexes are visible by default in MariaDB.
