如何使用Liquibase将存储过程导入到MySQL中？

我正在使用Gradle 2.7，MySQL 5.5.46和Liquibase-Gradle 1.1.1插件。我有一个存储过程看起来像...如何使用Liquibase将存储过程导入到MySQL中？

DELIMITER // 

DROP PROCEDURE IF EXISTS MyProc; 

CREATE PROCEDURE MyProc(
IN param1 VARCHAR(25), 
IN param2 VARCHAR(5), 
OUT outParam VARCHAR(2500)) 

BEGIN 
… 
END //

我能够导入这个文件很好的MySQL命令行。然而，当我创建这个Liquibase变更...

<changeSet id="create_my_stored_proc" author="davea"> 
    <sqlFile path="src/main/resources/scripts/my_stored_proc.sql" stripComments="true"/> 
</changeSet>

，并运行它，我得到的错误

什么我需要做的，纠正这一错误？

编辑：我删除每个答案的“分隔符”行让我的文件看起来像......

DROP PROCEDURE IF EXISTS MyProd; 

CREATE PROCEDURE MyProc(
IN param1 VARCHAR(25), 
IN param2 VARCHAR(5), 
OUT outParam VARCHAR(2500)) 

BEGIN 
… 
END //

然而，在运行变更我得到这个错误...

相反与在文件中指定分隔符相比，您必须在更改中指定它。要做到这一点，请从SQL文件，其中包含DELIMITER行，然后改变变更，所以它看起来是这样的：

<changeSet id="create_my_stored_proc" author="davea"> 
    <sqlFile endDelimiter="//" path="src/main/resources/scripts/my_stored_proc.sql" stripComments="true" /> 
</changeSet>

感谢您的答复保持在SQLFILE这一说法。我删除了DELIMTER行，根据您的建议并更新了适当的更改集，但仍然收到错误（包含在我的问题中）。请注意，使用DELIMITER参数，我可以通过MySQL命令行导入文件。 – Dave

K，删除“DROP PROCEDURE”行也允许正常运行。 – Dave

MySQL命令行允许的命令与通过JDBC驱动程序发送命令时允许的命令不同，并且并不总是清楚在哪里允许哪些命令。其他数据库也是如此。使用Oracle sqlplus命令行可以执行的操作与通过驱动程序运行普通SQL时允许执行的操作不同。 – SteveDonie

对于LiquiBase创建过程需要使用XML创建过程中，它会解决你的问题。也编译它并检查是否没有错误。

<changeSet id="create_my_stored_proc" author="davea"> 
<createProcedure path="src/main/resources/scripts/my_stored_proc.sql"/> 
<sql>alter procedure MyProc compile;</sql> 
<sql>call MyProc();</sql> 
<changeSet id="create_my_stored_proc" author="davea">

线

DROP PROCEDURE IF EXISTS MyProc;

与您的编辑过的文件生成的错误，因为它具有默认定界符（;）结束，而分隔符已被更改为//。你可以使用变更后的分隔符//，即：

DROP PROCEDURE IF EXISTS MyProc //
