flyway mysqldump遷移

Question

我越瞭解flyway對數據庫遷移的影響，我越喜歡它。

我試圖讓遷飛閱讀從mysqldump的-d產生的遷移和我偶然發現了一些奇怪的行爲。

在主頁上，它說

DDL通過mysqldump的出口可以在遷飛路線遷移不變地使用。

我的經驗是有點不同。 你如何使用mysqldump與flyway生成的文件？

我是想：

我嘗試用

mysqldump -h host --user=user -p -d --hex-blob databasename > V1__Basic.sql 

這並不工作，並給了我一個文件，它看起來像這樣得到的DDL（是的，它是一個來自Activiti的數據庫方案:)）：

-- MySQL dump 10.13 Distrib 5.5.28, for osx10.6 (i386)

-- 

DROP TABLE IF EXISTS `ACT_GE_BYTEARRAY`; 
/*!40101 SET @saved_cs_client  = @@character_set_client */; 
/*!40101 SET character_set_client = utf8 */; 
CREATE TABLE `ACT_GE_BYTEARRAY` (
    `ID_` varchar(64) COLLATE utf8_bin NOT NULL DEFAULT '', 
    `REV_` int(11) DEFAULT NULL, 
    `NAME_` varchar(255) COLLATE utf8_bin DEFAULT NULL, 
    `DEPLOYMENT_ID_` varchar(64) COLLATE utf8_bin DEFAULT NULL, 
    `BYTES_` longblob, 
    `GENERATED_` tinyint(4) DEFAULT NULL, 
    PRIMARY KEY (`ID_`), 
    KEY `ACT_FK_BYTEARR_DEPL` (`DEPLOYMENT_ID_`), 
    CONSTRAINT `ACT_FK_BYTEARR_DEPL` FOREIGN KEY (`DEPLOYMENT_ID_`) REFERENCES  `ACT_RE_DEPLOYMENT` (`ID_`) 
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin; 
/*!40101 SET character_set_client = @saved_cs_client */; 

-- 
-- Table structure for table `ACT_GE_PROPERTY` 
-- 

DROP TABLE IF EXISTS `ACT_GE_PROPERTY`; 
/*!40101 SET @saved_cs_client  = @@character_set_client */; 
/*!40101 SET character_set_client = utf8 */; 

依此類推。

我有遷徙路線設置（簡單的彈簧集成），並且拿起文件。 然而，它沒有做任何事情（不執行SQL）：

INFO @ 14 Mar 2013 22:34:41,646 @ com.googlecode.flyway.core.command.DbMigrate - Current version of schema "PUBLIC": << Empty Schema >> 
INFO @ 14 Mar 2013 22:34:41,647 @ com.googlecode.flyway.core.command.DbMigrate - Migrating schema "PUBLIC" to version 1

但是，如果我第一個SQL語句之前刪除所有行（DROP TABLE）遷徙路線只執行刪除表，之後停止。

DEBUG @ 14 Mar 2013 22:34:41,698 @ com.googlecode.flyway.core.dbsupport.SqlScript - Found statement at line 1: DROP TABLE IF EXISTS `ACT_GE_BYTEARRAY`

如果我刪除了一切的CREATE TABLE遷徙路線不喜歡的語法

ERROR @ 14 Mar 2013 22:45:01,270 @ com.googlecode.flyway.core.command.DbMigrate - Caused by org.h2.jdbc.JdbcSQLException: Syntax error in SQL statement "CREATE TABLE ""ACT_GE_BYTEARRAY"" (
    ""ID_"" VARCHAR(64) COLLATE[*] UTF8_BIN NOT NULL DEFAULT '', 

我怎樣才能得到mysqldump的東西飛路的輸出會喜歡？ 非常感謝你們！

Flyway的解析器是特定於DB的。由於您試圖導入到H2中，因此它會嘗試解析H2語法而不是解析mysql語法。導入到MySQL數據庫，你應該很好去。
