创建表空间&PL/SQL语法

-- 首先在数据目录创建finance_dev文件夹
-- 创建表空间
CREATE SMALLFILE TABLESPACE finance_dev 
DATAFILE 'D:DatabaseOracleoradatafinance_devfinance_dev.ora' SIZE 10M
EXTENT MANAGEMENT LOCAL AUTOALLOCATE;
-- 创建用户及登录密码
CREATE USER finance_dev IDENTIFIED BY finance_dev123;
-- 授权表空间
GRANT CONNECT TO finance_dev;
GRANT RESOURCE TO finance_dev;
GRANT DBA TO finance_dev;

使用Sqlplus登录

CREATE TABLE f_order (
    id         INTEGER NOT NULL PRIMARY KEY,
    f_order    VARCHAR2(30 CHAR) NOT NULL,
    hy_code    VARCHAR2(30 CHAR) NOT NULL,
    hy_name    VARCHAR2(50 CHAR) NOT NULL,
    status     VARCHAR2(30 CHAR) NOT NULL,
    add_time   TIMESTAMP(6)
);

DECLARE
    hyname       VARCHAR2(10) := 'world';
    fordercode   VARCHAR2(10) := 'f03';
BEGIN
    UPDATE f_order
        SET
            hy_name = hyname
    WHERE
        f_order_code = fordercode;

    IF
        SQL%notfound
    THEN
        INSERT INTO f_order VALUES (
            f_order_seq.NEXTVAL,
            'f03',
            '180231777',
            'hhh',
            '3',
            SYSDATE
        );

    END IF;

END;
