使用Grails数据库迁移插件创建和运行存储过程

Question

我正在尝试进行一个稍微麻烦的数据库迁移，并且正在使用存储过程来更新应用程序表之一中的某些行。 如果使用mysql命令行工具或在Sequel Pro中执行存储过程，则该存储过程可以正常运行，但是，如果尝试使用数据库迁移插件运行该存储过程，则该存储过程不会运行。

看起来liquibase支持存储过程，但是数据库迁移插件似乎崩溃了。 有人知道这是否应该工作吗？

错误（和完整的存储过程）如下所示：

Answer 1

定义存储过程时，请尝试使用splitStatements ，例如：

sqlFile path:'my_stored_procedure.sql', splitStatements: false

否则，数据库迁移插件将尝试变得更聪明，并拆分您的语句，这将破坏您的定义。

Answer 2

runOnChange ='true'配置强制插件检查更改集是否已更改，而不是仅检查更改集之前是否已运行过一次，因此可以跳过该更改集。

默认情况下，将文件中的sql语句拆分为;以避免这种splitStatements ='false'配置用于确保将完整的创建过程脚本读取为一个，而不是针对每个单独的sql语句将其拆分为;内。

例：

changeSet(author: "Rahul", id: "1435600003872-128", runOnChange: "true") {
    sql("DROP PROCEDURE IF EXISTS BestCustomers;")
    sqlFile(path: "../sql/BestCustomers.sql", splitStatements: false)
}

BestCustomers.sql的代码：

CREATE PROCEDURE `BestCustomers`(
     //Input params here
   )
BEGIN
    //Sql scripts here ;
END
