-- 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,

-- 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

-- 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
);
