ORA-02267: 列类型与引用的列类型不兼容

Question

这是我在 SQL 中的编码：

CREATE TABLE TICKET (
  TICKET_NO NUMBER,
  VENUE_NO VARCHAR(3),
  TICKET_DATE   DATE,
  TICKET_PRICE NUMBER(8,2),
  PRIMARY KEY (TICKET_NO), 
    CONSTRAINT TICKET_VENUE_NO_FK
  FOREIGN KEY (VENUE_NO) REFERENCES VENUE
);

这是错误说明：

Error starting at line 1 in command:
CREATE TABLE TICKET (
TICKET_NO   NUMBER,
VENUE_NO VARCHAR(3),
TICKET_DATE DATE,
TICKET_PRICE NUMBER(8,2),
PRIMARY KEY (TICKET_NO), 
 CONSTRAINT TICKET_VENUE_NO_FK
FOREIGN KEY (VENUE_NO) REFERENCES VENUE)
Error at Command Line:8 Column:13
Error report:
SQL Error: ORA-02267: column type incompatible with referenced column type
02267. 00000 -  "column type incompatible with referenced column type"
*Cause:    The datatype of the referencing column is incompatible with the

我的编码有什么问题？
