Tarantool Sql 更新加入支持

Tarantool Sql Update Join Support

tarantool 是否支持更新连接?我正在检查 tarantool sql 参考资料,但找不到任何样本。 当我尝试使用类似于下面的查询时,出现错误。

UPDATE
    COMMISSIONS
SET
    COMMISSIONS.COMMISSION = 
        COMMISSIONS.BASE_AMOUNT * TARGETS.PERCENTAGE
FROM 
    COMMISSIONS
    INNER JOIN TARGETS
        ON COMMISSIONS.TARGET_ID = TARGETS.TARGET_ID;

这是架构定义:

CREATE TABLE COMMISSIONS
(
    STAFF_ID    INTEGER PRIMARY KEY, 
    TARGET_ID   INTEGER, 
    BASE_AMOUNT INTEGER, 
    COMMISSION  INTEGER
);

CREATE TABLE TARGETS
(
    TARGET_ID  INTEGER  PRIMARY KEY, 
    PERCENTAGE INTEGER
);


INSERT INTO 
    TARGETS(TARGET_ID, PERCENTAGE)
VALUES
    (1,20),
    (2,30),
    (3,50),
    (4,60),
    (5,80);
    
   
INSERT INTO 
    COMMISSIONS(STAFF_ID, BASE_AMOUNT, TARGET_ID)
VALUES
    (1,100000,2),
    (2,120000,1),
    (3,80000,3),
    (4,900000,4),
    (5,950000,5);

这是我在 运行 更新命令时得到的错误:

Caused by: org.tarantool.TarantoolException: Syntax error at line 1 near '.'
    at org.tarantool.TarantoolBase.serverError(TarantoolBase.java:31)
    at org.tarantool.TarantoolClientImpl.complete(TarantoolClientImpl.java:571)

    at java.base/java.lang.Thread.run(Unknown Source)

PS:我正在使用 dbeaver + tarantool jdbc 驱动程序来 运行 查询是否有任何区别。

您可以使用子查询,如下所示:

UPDATE COMMISSIONS SET COMMISSION = 
(
    SELECT COMMISSIONS.BASE_AMOUNT * TARGETS.PERCENTAGE 
    FROM TARGETS 
    WHERE COMMISSIONS.TARGET_ID = TARGETS.TARGET_ID
);

我们的SQL方言来源于SQLite,所以你也可以查看这个相关答案:Update with Join in SQLite
