ORA-00906: 缺少左括号 - 谎言？

Question

我一直盯着这个直到我的眼球流血，我在哪里缺少括号？它也说

从第 1 行开始的错误命令-"。

错误报告的原因和操作部分为空白。

CREATE TABLE EVENTREQUEST(
    EVENTNO VARCHAR2(8) CONSTRAINT EVENTNO_NOTNULL NOT NULL,
    DATEHELD DATE CONSTRAINT DATEHELD_NOTNULL NOT NULL,
    DATEREQ DATE CONSTRAINT DATEREQ_NOTNULL NOT NULL,
    CUSTNO VARCHAR2(8) CONSTRAINT CUSTNO_NOTNULL2 NOT NULL,
    FACNO VARCHAR2(8) CONSTRAINT CUSTNO_NOTNULL2 NOT NULL,
    DATEAUTH DATE,
    STATUS VARCHAR2(15) CHECK (STATUS IN ('Pending', 'Denied', 'Approved')) CONSTRAINT STATUS_NOTNULL NOT NULL,
    ESTCOAST VARCHAR2(30) CONSTRAINT ESTCOAST_NOTNULL NOT NULL,
    ESTAUDIENCE VARCHAR2(30) CHECK(ESTAUDIENCE > 0) CONSTRAINT ESTAUDIENCE_NOTNULL NOT NULL,
    BUDNO VARCHAR2(8),
    CONSTRAINT PK_EVENTNO PRIMARY KEY,
    CONSTRAINT FK_CUSTONO FOREIGN KEY (CUSTNO) REFERENCES CUSTOMER(CUSTNO),
    CONSTRAINT FK_FACNO FOREIGN KEY (FACNO) REFERENCES FACILITY(FACNO)
);

这只是因为您在声明主键时错过了列名。还有一个问题：第四列和第五列的约束名称相同。我也改了。

并且没有必要声明CONSTRAINT EVENTNO_NOTNULL NOT NULL，因为您将其声明为主键。

CREATE TABLE EVENTREQUEST(
EVENTNO VARCHAR2(8) CONSTRAINT EVENTNO_NOTNULL NOT NULL,
DATEHELD DATE CONSTRAINT DATEHELD_NOTNULL NOT NULL,
DATEREQ DATE CONSTRAINT DATEREQ_NOTNULL NOT NULL,
CUSTNO VARCHAR2(8) CONSTRAINT CUSTNO_NOTNULL2 NOT NULL,
FACNO VARCHAR2(8) CONSTRAINT FACNO_NOTNULL2 NOT NULL,
DATEAUTH DATE,
STATUS VARCHAR2(15) CHECK (STATUS IN ('Pending', 'Denied', 'Approved')) CONSTRAINT STATUS_NOTNULL NOT NULL,
ESTCOAST VARCHAR2(30) CONSTRAINT ESTCOAST_NOTNULL NOT NULL,
ESTAUDIENCE VARCHAR2(30) CHECK(ESTAUDIENCE > 0) CONSTRAINT ESTAUDIENCE_NOTNULL NOT NULL,
BUDNO VARCHAR2(8),
CONSTRAINT PK_EVENTNO PRIMARY KEY (EVENTNO),
CONSTRAINT FK_CUSTONO FOREIGN KEY (CUSTNO) REFERENCES CUSTOMER(CUSTNO),
CONSTRAINT FK_FACNO FOREIGN KEY (FACNO) REFERENCES FACILITY(FACNO));
