向表中插入数据时出现 ORA-00001 和 ORA-01438 错误

Question

我在尝试运行此脚本时遇到问题：

ORA-00001：违反了唯一约束（constraint_name）

所以，问题是不能在表中插入日期，其他错误是：

ORA-01438: 该列允许的值大于指定的精度

CREATE TABLE TEST

    COMPONENTS     VARCHAR2(30) NOT NULL,
    MATTER        VARCHAR2(2) NOT NULL,
    LIC            NUMBER(9, 2),
    MIC            NUMBER(9, 2),
    UIP            NUMBER(9, 2),
    CONSTRAINT TEST_pk PRIMARY KEY (TEST_ID));

Answer 1

您可以将序列缓存大小增加到200，默认为20。

alter sequence SEQ_TEST_ID cache 200;

试试agian。

Answer 2

如果你在oracle中创建表，那么AUTO_INCREMENT是不支持的。

使用MSW_ID 作为数字创建表，并创建一个序列以在表中使用它的值。

CREATE TABLE MSW

( MSW_ID number, 
 COMPONENTS VARCHAR2(15) NOT NULL, 
 MATTER VARCHAR2(2) NOT NULL, 
 LIC NUMBER(4, 2), 
 MIC NUMBER(4, 2), 
 UIP NUMBER(4, 2), 
 CONSTRAINT NSW_pk PRIMARY KEY (MSW_ID));

您可以了解更多关于序列的信息here；

CREATE SEQUENCE SEQ_MSW_ID
 START WITH     1
 INCREMENT BY   1
 MINVALUE 1
 MAXVALUE 99999999999;

然后你插入查询就变成了

INSERT  INTO MSW ( MSW_ID, COMPONENTS, MATTER, LIC, MIC, UIP) VALUES
                (SEQ_MSW_ID.NEXTVAL, 'Food waste'   ,'OG','50.50','39.00','13.00'); --> semicolon
INSERT  INTO MSW ( MSW_ID, COMPONENTS, MATTER, LIC, MIC, UIP) VALUES
                 (SEQ_MSW_ID.NEXTVAL, 'Paper'        ,'OG','05.50','19.00','32.50');  --> semicolon
.
.
.
INSERT  INTO MSW ( MSW_ID, COMPONENTS, MATTER, LIC, MIC, UIP) VALUES
                 (SEQ_MSW_ID.NEXTVAL, 'Drit,ash,etc' ,'IG','20.50','15.50','05.00');  --> semicolon

或者使用 insert all 作为单个语句作为

INSERT ALL 
     INTO MSW ( MSW_ID, COMPONENTS, MATTER, LIC, MIC, UIP) VALUES
                (SEQ_MSW_ID.NEXTVAL, 'Food waste'   ,'OG','50.50','39.00','13.00')
     INTO MSW ( MSW_ID, COMPONENTS, MATTER, LIC, MIC, UIP) VALUES
                (SEQ_MSW_ID.NEXTVAL, 'Paper'        ,'OG','05.50','19.00','32.50')
     .
     .
     .
     INTO MSW ( MSW_ID, COMPONENTS, MATTER, LIC, MIC, UIP) VALUES
                (SEQ_MSW_ID.NEXTVAL, 'Drit,ash,etc' ,'IG','20.50','15.50','05.00')
SELECT * FROM DUAL;  --> semicolon

Answer 3

错误消息是由于int() 中的额外括号造成的。

SQL> create table foo(f int());
create table foo(f int())
                      *
ERROR at line 1:
ORA-00907: missing right parenthesis


SQL> create table foo(f int);

Table created.

SQL> 

顺便说一句。这个问题与 PL/SQL 无关，这是一个普通的 Oracle SQL 问题。
