如何使用Liquibase将存储过程导入MySQL？

Question

我正在使用Gradle 2.7,MySQL 5.5.46和Liquibase-Gradle 1.1.1插件.我有一个文件,其存储过程看起来像......

DELIMITER //

DROP PROCEDURE IF EXISTS MyProc;

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

BEGIN
…
END //

我可以在MySQL命令行上很好地导入这个文件.但是,当我创建这个Liquibase变更集时......

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

运行它,我得到错误

我需要做些什么才能纠正此错误？

编辑:我根据答案删除了"DELIMITER"行,使我的文件看起来像......

DROP PROCEDURE IF EXISTS MyProd;

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

BEGIN
…
END //

但是,在运行变更集时,我收到此错误...

Answer 1

线

DROP PROCEDURE IF EXISTS MyProc;

使用您编辑的文件生成错误，因为它以默认分隔符 ( ; )结尾，而分隔符已更改为//。您可以使用更改后的分隔符//将此语句保留在 sqlFile 中，即：

DROP PROCEDURE IF EXISTS MyProc //

Answer 2

您必须在更改中指定它,而不是在文件中指定分隔符.为此,删除包含DELIMITERsql文件的行,然后更改变更集,使其如下所示:

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