Oracle创建表、索引、主键、字段描述

-- 创建表
create table SX04_LBALANCE
(
  YEAR        VARCHAR2(10) not null,
  PROGRAMNO   VARCHAR2(40) not null,
  FDATE       VARCHAR2(10) not null,
  FACCTCODE   VARCHAR2(50) not null,
  FCURCODE    VARCHAR2(3) not null,
  FAACCCREDIT NUMBER(19,4) default 0 not null,
  FAENDBAL    NUMBER(19,4) default 0 not null,
  FISDETAIL   NUMBER(3) not null
)
--表所在表空间

-- 字段描述
comment on column SX04_LBALANCE.INPUT_DT
  is ‘数据日期‘;
-- 添加主键
alter table SX04_LBALANCE
  add primary key (YEAR, PROGRAMNO, FACCTCODE, FDATE)
  using index 
  tablespace ISTAUDIT
  pctfree 10
  initrans 2
  maxtrans 255
  storage
  (
    initial 93M
    minextents 1
    maxextents unlimited
  );
-- 创建索引  多个索引可连续创建  如下
create index CODE_INDEX on SX04_LBALANCE (FACCTCODE)
  tablespace ISTAUDIT
  pctfree 10
  initrans 2
  maxtrans 255
  storage
  (
    initial 64K
    minextents 1
    maxextents unlimited
  );
create index FDATE_INDEX on SX04_LBALANCE (FDATE)
  tablespace ISTAUDIT
  pctfree 10
  initrans 2
  maxtrans 255
  storage
  (
    initial 64K
    minextents 1
    maxextents unlimited
  );
