通過liquibase創建表時MySQL錯誤

Question

我通過數據庫遷移插件0.2.1使用了Grails 1.3.7 + MySQL 5.5 + Liquibase。

當我在我的開發環境中時，我將Hibernate配置爲使用「創建 - 刪除」，但在我的QA環境中，我想使用liquibase創建我的表。這裏是我的環境配置：

environments { 
    development { 
     dataSource { 
      configClass = GrailsAnnotationConfiguration.class 
      pooled = false 
      driverClassName = "com.mysql.jdbc.Driver" 
      username = "root" 
      password = "" 
      dialect = "org.hibernate.dialect.MySQL5InnoDBDialect" 
      dbCreate = "create-drop" 
      url = "jdbc:mysql://localhost/dripita_dev"  
     } 
    } 
    localQa { 
     dataSource { 
      configClass=GrailsAnnotationConfiguration.class 
      pooled=false 
      driverClassName="com.mysql.jdbc.Driver" 
      username="root" 
      password="" 
      dialect="org.hibernate.dialect.MySQL5InnoDBDialect" 
      url="jdbc:mysql://localhost/dripita_localqa"   
     } 
    } 
... 
} 

當我把應用程序在開發模式下，數據庫表創建罰款。我做了以下內容來創建的changelog：

$ grails dbm-generate-gorm-changelog changelog.groovy 

，看起來像這樣：

changeSet(author: "javidjamae (generated)", id: "1309959832163-2") { 
    createTable(tableName: "payment") { 
     column(autoIncrement: "true", name: "id", type: "bigint") { 
      constraints(nullable: "false", primaryKey: "true", primaryKeyName: "paymentPK") 
     } 

     column(name: "version", type: "bigint") { 
      constraints(nullable: "false") 
     } 

     column(name: "buyer_id", type: "bigint") { 
      constraints(nullable: "false") 
     } 

     column(name: "buyer_information_id", type: "bigint") 

     column(name: "currency", type: "varchar(255)") { 
      constraints(nullable: "false") 
     } 

     column(name: "discount_cart_amount", type: "decimal(19,2)") { 
      constraints(nullable: "false") 
     } 

     column(name: "paypal_transaction_id", type: "varchar(255)") 

     column(name: "status", type: "varchar(9)") { 
      constraints(nullable: "false") 
     } 

     column(name: "tax", type: "double precision(19)") { 
      constraints(nullable: "false") 
     } 

     column(name: "transaction_id", type: "varchar(255)") 
    } 
} 

然後我嘗試創建從更新日誌表：

$ grails -Dgrails.env=localQa dbm-update 

但是，當我運行dbm-update，出現以下錯誤：

07/06 08:52:41 INFO [main]: liquibase - Successfully acquired change log lock

當我在MySQL中複製/粘貼create語句時，出現同樣的錯誤。我甚至將ENGINE = InnoDB關閉，看是否有所作爲，但事實並非如此。有任何想法嗎？

僅供參考：我在我的Mac上使用HomeBrew安裝了MySQL。

我的猜測是你的QA數據庫不知道數據類型double precision(19)是什麼。
嘗試將其更改爲只需double precision。

如果失敗了，可以考慮使用其它數據類型：該doc說，雙精度是一個「非標準變化」
