I need reg_date
column value to be generated automatically as current system date.
This statement:
CREATE TABLE medina_student (
sno NUMBER(7) NOT NULL,
sname VARCHAR2(20) NOT NULL,
dept VARCHAR2(5) NOT NULL,
reg_date DATE DEFAULT 'sysdate' NOT NULL,
CONSTRAINT sno_pk PRIMARY KEY (sno),
CONSTRAINT sna_u UNIQUE (sname)
);
produces an error
reg_date date default 'sysdate' not null ,
*
ERROR at line 5:
ORA-01858: a non-numeric character was found where a numeric was expected
How to fix it?
错误确实在第5行中,删除'
:
reg_date date default sysdate not null
