讓oracle幫你理財

本案例以建設銀行為例

請將建行的交易明細表載下，並命名為ccb.txt

此時，你有兩種選擇：sqlldr or external table

㈠ sqlldr

因為網銀只有在win上才能用，所以如果你的os是linux/unix，那麼在ctl中必須指定字符集

讓utf-8可以顯示gb18030

① 建表

create table t_bank_invoice 
( account_number   number,
sub_number       number,
transac_date     date,
transac_address  varchar2(600),
transac_comment  varchar2(600),
currency         varchar2(100),
remit            varchar2(100),
in_amount        number(20,2),
out_amount       number(20,2),
balance          number(20,2),
opposite_number  number,
opposite_username varchar2(100),
all_comment       varchar2(2000));

② 用sqlldr

[oracle@localhost ~]$ sqlldr hr/hr control=ccb.ctl

ccb.ctl如下：

[oracle@localhost ~]$ sqlldr hr/hr control=ccb.ctl ccb.ctl如下： load data characterset zhs16gbk infile 'ccb.txt' discardfile 'ccb.dis' into table t_bank_invoice trailing nullcols ( account_number "11111111111", sub_number "00000", transac_date position(1:8) date(8) "yyyymmdd" terminated by ',', transac_address position(10) char terminated by ',', out_amount decimal external terminated by ',' nullif out_amount=blanks, in_amount decimal external terminated by ',' nullif in_amount=blanks , balance decimal external terminated by ',' nullif balance=blanks, opposite_number char terminated by ',', opposite_username char terminated by ',', currency char terminated by ',', transac_comment char terminated by whitespace

)

③ 查詢表

當然、你可以在all_comment列個性化設定你的具體消費開支，比如，交**費多少錢、買衣服多少錢等等

㈡ external table

① 建立directory物件

sys@orcl> create directory dir as '/home/oracle/';
directory created.
sys@orcl> grant read,write on directory dir to public;
grant succeeded.

② 把ccb.txt放在dir下

③ 用sqlldr生成外部表的建立語句，並編輯ccb.log

編輯如下：

create table t_bank_invoice
(  "account_number" varchar(255),
"sub_number" varchar(255),
"transac_date" date,
"transac_address" varchar2(600),
"out_amount" number(20,2),
"in_amount" number(20,2),
"balance" number(20,2),
"opposite_number" number,
"opposite_username" varchar2(100),
"currency" varchar2(100),
"transac_comment" varchar2(600)
)organization external
(  type oracle_loader
default directory dir
access parameters
(    records delimited by newline characterset zhs16gbk
badfile 'ccb1.bad'
discardfile 'ccb1.dis'
logfile 'ccb.log_xt'
readsize 1048576
fields ldrtrim
missing field values are null
reject rows with all null fields
("account_number" char(1),
"sub_number" char(1),
"transac_date" (1:8) char(8)
date_format date mask "yyyymmdd",
"transac_address" (10) char(255)
terminated by ",",
"out_amount" char(255)
terminated by ","
nullif ("out_amount" = blanks),
"in_amount" char(255)
terminated by ","
nullif ("in_amount" = blanks),
"balance" char(255)
terminated by ","
nullif ("balance" = blanks),
"opposite_number" char(255)
terminated by ",",
"opposite_username" char(255)
terminated by ",",
"currency" char(255)
terminated by ",",
"transac_comment" char(255)
terminated by whitespace
))  location
(    'ccb.txt'
))reject limit unlimited;

④

[oracle@localhost ~]$ cp ccb.log ccb.sql

⑤

hr@orcl> @ccb.sql
table created.

⑥ 查詢表

小結：如果您的存款驚人、或者經常訪問，明細比較大、外部表是個不錯的選擇

但不論是sqlldr還是external table

都是為了方便我們理財、讓我們的生活更厚重和精彩
