Sql Can'；t使用架构名称更新表值

我无法执行最后一个查询。 警告说应该是“加入”而不是“.”，但我不知道如何修复它。

---

由于表名包含架构，无法更新表值。是否有任何方法更新该值？

table

不是

update

语法的一部分。我建议你试试：

CREATE TABLE DBD_D_155150401111052.STUDENT(
    STUDENT_ID VARCHAR(20) NOT NULL,
    PRIMARY KEY (STUDENT_ID),
    STATE_ID CHAR(3),
    CONSTRAINT STATE_ID FOREIGN KEY (STATE_ID) REFERENCES DBD_D_155150401111052.PROPINSI (STATE_ID),
    CITY_ID CHAR(3),
    CONSTRAINT CITY_ID FOREIGN KEY (CITY_ID) REFERENCES DBD_D_155150401111052.KOTA (CITY_ID),
    NAME VARCHAR(45),
    BIRTH_DATE DATE,
    COURSE VARCHAR(10)
    );

INSERT INTO DBD_D_155150401111052.STUDENT (STUDENT_ID, NAME, BIRTH_DATE, CITY_ID, STATE_ID, COURSE)

尝试

Update[DBD_1551504011111052.STUDENT]

看起来像是有人建议您

updatetablename SET..

但应该是

updatetablename SET..

您使用的是哪种数据库管理系统？尝试

Update[DBD_1554011111052.STUDENT]

看起来像是有人建议您

更新表TABLENAME SET..

但它应该是

更新TABLENAME SET..

您使用的是哪种DBMS？
