Oracle insert into returning
提问by Wulpo
I'm trying return id after insert:
我正在尝试插入后返回 id：
CREATE SEQUENCE seq_osobne_udaje
INCREMENT BY 1 START WITH 1;
CREATE OR REPLACE TRIGGER trig_osobne_udaje_seq
BEFORE INSERT ON osobne_udaje
FOR EACH ROW
BEGIN
SELECT seq_osobne_udaje.nextval INTO :new.id FROM dual;
END;
/
and then:
进而：
var tmp number;
insert into osobne_udaje(name,sur,born,is_man)
values('Jacob','Wulp',to_date('28.07.1992','DD.MM.YYYY'),'Y')
returning id into tmp;
but it write exception in insert row: SQL Error: ORA-00905: missing keyword
但它在插入行中写入异常：SQL 错误：ORA-00905：缺少关键字

This script works in SQL Developer:
此脚本适用于 SQL Developer：
DROP TRIGGER trig_osobne_udaje_seq;
DROP SEQUENCE seq_osobne_udaje;
DROP table osobne_udaje;
create table osobne_udaje(
id NUMBER,
name VARCHAR2(20),
sur VARCHAR2(20),
born DATE,
is_man CHAR(1)
)
/
CREATE SEQUENCE seq_osobne_udaje
INCREMENT BY 1 START WITH 1;
/
CREATE OR REPLACE TRIGGER trig_osobne_udaje_seq
BEFORE INSERT ON osobne_udaje
FOR EACH ROW
BEGIN
:new.id := seq_osobne_udaje.nextval;
END;
/
var tmp number;
/
BEGIN
insert into osobne_udaje(name,sur,born,is_man)
values('Jacob','Wulp',to_date('28.07.1992','DD.MM.YYYY'),'Y')
returning id into :tmp;
END;
/
print tmp;
