HSQL - 意外的令牌：语句中的 PROCEDURE

【中文标题】HSQL - 意外的令牌：语句中的 PROCEDURE

【英文标题】：HSQL - Unexpected token: PROCEDURE in statement

【问题描述】：

我正在尝试转换存储过程以在 HSQL DB 中使用以进行集成测试。这里的 SQL 已经足够基本了——我们只是返回一组虚拟数据

CREATE PROCEDURE policy_Attribution(p_valDate Date) 
    MODIFIES SQL DATA
    BEGIN ATOMIC
    CREATE TABLE #retvals ( 
        Policy_ID INT, 
        Attribution_Name CHAR(64), 
        Attribution_Type CHAR(20), 
        Risk CHAR(20), 
        Revenue FLOAT, 
        Claims FLOAT 
    )
    INSERT INTO #retvals VALUES (1, 'name', 'type', 'risk', 1.5, 1.6)
    INSERT INTO #retvals VALUES (2, 'name2', 'type2', 'risk2', 0.5, 0.6) 
    INSERT INTO #retvals VALUES (3, 'name3', 'type3', 'risk3', 2.5, 2.6)
    SELECT * FROM #retvals
END

当我运行我的测试时，它失败了，因为数据库是用这个错误初始化的

Caused by: org.springframework.jdbc.datasource.init.ScriptStatementFailedException: Failed to execute SQL script statement at line 19 of resource class path resource [hsql/attribution-hsqldb.sql]:  CREATE PROCEDURE policy_Attribution(p_valDate Date)   MODIFIES SQL DATA  BEGIN ATOMIC  CREATE TABLE #retvals (    Policy_ID INT,    Attribution_Name CHAR(64),    Attribution_Type CHAR(20),    Risk CHAR(20),    Revenue FLOAT,    Claims FLOAT   )  INSERT INTO #retvals VALUES (1, 'name', 'type', 'risk', 1.5, 1.6)  INSERT INTO #retvals VALUES (2, 'name2', 'type2', 'risk2', 0.5, 0.6)   INSERT INTO #retvals VALUES (3, 'name3', 'type3', 'risk3', 2.5, 2.6)  SELECT * FROM #retvals END

hsqldb 抱怨的意外令牌是什么？

【参考方案1】：

应使用 DECLARE 关键字创建表。还需要进行其他更改：

CREATE PROCEDURE policy_Attribution(p_valDate Date) 
    MODIFIES SQL DATA
    BEGIN ATOMIC
    DECLARE TABLE retvals ( 
        Policy_ID INT, 
        Attribution_Name CHAR(64), 
        Attribution_Type CHAR(20), 
        Risk CHAR(20), 
        Revenue FLOAT, 
        Claims FLOAT 
    );
    BEGIN

    INSERT INTO retvals VALUES (1, 'name', 'type', 'risk', 1.5, 1.6);
    INSERT INTO retvals VALUES (2, 'name2', 'type2', 'risk2', 0.5, 0.6); 
    INSERT INTO retvals VALUES (3, 'name3', 'type3', 'risk3', 2.5, 2.6);
    DECLARE result CURSOR FOR SELECT * FROM retvals;
    OPEN result;
    END;
END

【参考方案2】：

也许缺少分号是问题所在。尝试将它们添加到每个 SQL 语句的末尾。
