繼續之前的讀書筆記，廢話少說，直奔主題。

四.連接數據庫的方式

libname形式：

Oracle?鏈接：Libname??IBMSHCU oracle user=bi password=bi schema=educ;

DB2鏈接：libname hsdb db2 user=xxx password="xxx"??datasrc=datadb;

?

passthrough方式(通過connect語句簡歷sas與外界數據庫之間的?通信)：

Proc sql ;

??connect to teradata(user=xxx??password=xxx??database=access_views??tdpid="xxx"?mode=teradata);

???create table sas_tb as select * from connection teradata

????(select * from test.tb1);

??disconnect from teradata;

Quit;
?

import方式（適用于txt、csv、excel、access等文件的導入）

libname IBMSHCU oracle user=bi password=test123 path=ibmshcu;

?

%let filepath=C:\Documents and Settings\Administrator\My Documents\01 work\01 project\cun;

%let filemonth=201202;

?

?

proc import datafile="&filepath.\副本存費贈費清單2月.xls"

??????out= newcharge_calllist_&filemonth.

??DBMS=EXCEL REPLACE;

?????SHEET="SQL Results$";

?????GETNAMES=yes;

?????MIXED=NO;

?????SCANTEXT=YES;

?????USEDATE=NO;

?????SCANTIME=YES;

run;

data??gcl_newcharge_calllist_&filemonth.;????????????????????????

set newcharge_calllist_&filemonth.;

rename?????_col0=device_number

???????????_col1=sellresult

???????_col2=sell_time

???_col3=seller_id

???;

run;

?

data??ibmshcu.gcl_newcharge_calllist_&filemonth.;

set gcl_newcharge_calllist_&filemonth.;

run;

?

除了以上代碼之外，還可以通過菜單的方式操作，通過file菜單下面有個import的菜單進行；

?

input方式（最復雜最不常用的方式）

?

另一種導入方式，不需要改列名：

libname IBMSHCU oracle user=bi password=test123 path=ibmshcu;

%let filepath=C:\Documents and Settings\Administrator\My Documents\01 work\01 project\cun;

%let filemonth=201112;

data??chongzhishiwu_&filemonth.;

length???order??8

?????????ACTIVITY_ID???$10.

?????????ACCT_MONTH????$6.

?????????ACCT_DATE?????$8.

?????????AREA_NO???????$6.

?????????AREA_NO_DESC??$20.

?????????INACTIVE_TIME $10.

?????????SUBS_OBJECT_UID $10.

?????????IS_3G_USER????$4.

?????????PAY_MODE??????$10.

?????????OPERATOR_NAME $10.

?????????CHANNEL_NAME??$50.

??????????????;

infile "&filepath.\充值送實物2011-12.TXT" dsd dlm='|' missover end=last firstobs=2;

do until(last);

input????order?

?????????ACTIVITY_ID???$

?????????ACCT_MONTH????$

?????????ACCT_DATE?????$

?????????AREA_NO???????$

?????????AREA_NO_DESC??$

?????????INACTIVE_TIME $

?????????SUBS_OBJECT_UID $

?????????IS_3G_USER????$

?????????PAY_MODE??????$

?????????OPERATOR_NAME $

?????????CHANNEL_NAME??$

???????;

output;

end;

drop order;

run;
