Question

我正在尝试在内存Hsqldb数据库中设置存储过程以进行测试。我正在使用的存储过程是在MySql中开发的，所以我想用HSqlDb设置它以适应我的测试套件

我正在尝试创建一个简化版本的程序，但目前尚无欢乐。

程序

     CREATE PROCEDURE p_recordTaskExecution(IN userTaskId INT, IN isSuccess BOOLEAN, IN statusMessage VARCHAR(2000), IN operationsPerformed INT, INOUT procedureStatus BOOLEAN) 
  BEGIN ATOMIC
  IF userTaskId = 1 Then
        set procedureStatus = true;

  ELSE
    set procedureStatus = false;

  END IF;

  END;

运行测试时遇到的错误如下

Caused by: org.springframework.jdbc.datasource.init.ScriptStatementFailedException: Failed to execute SQL script statement at line 3 of resource class path resource [databaseTesting/inMemory/createInMemoryDatabase.sql]: CREATE PROCEDURE p_recordTaskExecution(IN userTaskId INT, IN isSuccess BOOLEAN, IN statusMessage VARCHAR(2000), IN operationsPerformed INT, INOUT procedureStatus BOOLEAN) BEGIN ATOMIC if userTaskId = 1 Then set procedureStatus = true; nested exception is java.sql.SQLSyntaxErrorException: unexpected end of statement:  required: ;

Answer 1

由于以下stackoverflow链接，我终于得到了答案 HSQL Create Procedure Syntax doesn't seem to match the documentation

为了完整性，这就是我做的事情

我将hsqldb sql代码分成2个文件。 1只创建表和数据语法，另一个用存储过程

在此文件中加载时，我可以指定要使用的分隔符

<jdbc:initialize-database data-source="mctDBDataSource" ignore-failures="DROPS" >
    <jdbc:script location="classpath:databaseTesting/inMemory/createInMemoryDatabase.sql" separator=";"/>
    <jdbc:script location="classpath:databaseTesting/inMemory/createInMemoryDatabaseProcedures.sql" separator="/;"/>
</jdbc:initialize-database>

。如前所述，Spring治疗半结肠;作为语句的结尾，所以我能够指定一个不同的分隔符用于我的存储过程文件

更新了我的存储过程以使用新的分隔符，现在一切都按预期工作

CREATE PROCEDURE p_recordTaskExecution(IN userTaskId BIGINT, IN isSuccess BOOLEAN, IN statusMessage VARCHAR(2000), IN operationsPerformed BIGINT, INOUT procedureStatus BOOLEAN) 
BEGIN ATOMIC
    IF userTaskId = 1 Then
        SET procedureStatus = true; 
    ELSE
        SET procedureStatus = false;
    END IF;
END;
/;

Answer 2

这个与指定的@Damo相同但是避免了XML配置。

java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to java.util.List

这是方法签名：

ScriptUtils.executeSqlScript(ds.getConnection(),  new EncodedResource(
                new InputStreamResource(getClass().getClassLoader().getSystemResourceAsStream("procs.sql"))
                ), false, false, "--", "/;", "--", "--");

Answer 3

在END IF和END之后，您不需要分号。错误消息有点误导。

修改的您可能还需要在CREATE PROCEDURE...文本中加倍分号，因为Spring本身也将分号视为语句分隔符。
