MySQL工作臺正向工程錯誤1064個

Question

逗人，

我創建了一個數據庫模型，並hopeping腳本它MySQL的順利使用工作臺。

下面

是由WB生成的代碼：

遺憾的是執行一次我得到以下錯誤信息：

任何線索？

Answer 1

來自MY SQL手冊...我想你需要一個表達式。

生成列定義具有以下語法：

col_name data_type [GENERATED ALWAYS] AS (expression) 
    [VIRTUAL | STORED] [UNIQUE [KEY]] [COMMENT comment] 
    [[NOT] NULL] [[PRIMARY] KEY] 

AS（表達式）表示所產生的柱，並限定用於計算列值的表達。 AS之前可能會生成GENERATED ALWAYS，以使列的生成特性更加明確。表達式中允許或禁止的構造將在後面討論。

Answer 2

你的意思AUTO_INCREMENT

CREATE TABLE IF NOT EXISTS `resume_db`.`job_history` (
     `id` INT AUTO_INCREMENT, 
      `employerName` MEDIUMTEXT NOT NULL, 
      `employement_duration` VARCHAR(100) NULL, 
      `job_title` VARCHAR(256) NOT NULL, 
      `duties` VARCHAR(200) NULL, 
      `applications_id` INT NOT NULL, 
      PRIMARY KEY (`id`, `applications_id`)) 
     ENGINE = InnoDB 

否則，爲什麼生成一個虛擬的ID列？
