Question

我使用H2来测试我的数据库代码。为此，我首先阅读一组SQL文件并使用RunScript.execute来执行SQL。

我真正的数据库是MySQL，我测试了SQL脚本以确保它们正常工作。问题显然是在H2内部。这是一组脚本：

CREATE TABLE stores (
  id integer AUTO_INCREMENT PRIMARY KEY,
  name varchar(255) NOT NULL,
  UNIQUE(name),
  created_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  updated_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  deleted_at timestamp
);

CREATE TABLE regions (
  id integer AUTO_INCREMENT PRIMARY KEY,
  name varchar(255) NOT NULL,
  UNIQUE(name),
  created_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  updated_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  deleted_at timestamp
);


CREATE TABLE products (
  id integer AUTO_INCREMENT PRIMARY KEY,
  store_id integer NOT NULL,
  name varchar(255) NOT NULL,
  region_id integer NOT NULL,
  created_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  updated_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  deleted_at timestamp,
  UNIQUE(store_id, name),
  FOREIGN KEY store_fk(store_id) REFERENCES stores(id),
  FOREIGN KEY region_fk(region_id) REFERENCES regions(id)
);

使用MySQL Workbench运行这3个脚本来创建表可以正常工作。通过以下代码从JUnit运行它们不会：

Reader storeTableSql = new InputStreamReader(
    DatabaseConnectorTests.class.getResourceAsStream(
        "/migrations/V1__create_stores_table.sql"));

Reader regionTableSql = new InputStreamReader(
    DatabaseConnectorTests.class.getResourceAsStream(
        "/migrations/V2__create_regions_table.sql"));

Reader productTableSql = new InputStreamReader(
    DatabaseConnectorTests.class.getResourceAsStream(
        "/migrations/V3__create_products_table.sql"));

this.dc = DatabaseConnector.getConnection();
RunScript.execute(dc, storeTableSql);
RunScript.execute(dc, regionTableSql);
RunScript.execute(dc, productTableSql);

我收到以下错误：

org.h2.jdbc.JdbcSQLException: Syntax error in SQL statement "CREATE TABLE PRODUCTS (
  ID INTEGER AUTO_INCREMENT PRIMARY KEY,
  STORE_ID INTEGER NOT NULL,
  NAME VARCHAR(255) NOT NULL,
  REGION_ID INTEGER NOT NULL,
  CREATED_AT TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
  UPDATED_AT TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
  DELETED_AT TIMESTAMP,
  UNIQUE(STORE_ID, NAME),
  FOREIGN KEY STORE_FK[*](STORE_ID) REFERENCES STORES(ID),
  FOREIGN KEY REGION_FK(REGION_ID) REFERENCES REGIONS(ID)
) "; expected "("; SQL statement:

  UNIQUE(store_id, name),
  FOREIGN KEY store_fk(store_id) REFERENCES stores(id),
  FOREIGN KEY region_fk(region_id) REFERENCES regions(id)
) [42001-196]

此代码适用于MySQL，我在MySQL兼容模式下通过以下连接字符串运行H2：jdbc:h2:file:~/database;MODE=MySQL。我不知道我还能在这做什么。这个错误对我来说似乎很奇怪，因为我不知道它为什么会认为我需要另一个(。

有谁知道如何解决这个问题？或者对如何种植我的测试数据库有更好的建议？由于对我运行的系统的限制，我无法使用hibernate执行此任务，因此我不得不手动执行大量操作。

谢谢！
