一、創建存儲過程

ps：將需要導出數據的sql語句替換下面的sql語句和下面的字段

 1 CREATE OR REPLACE PROCEDURE Export_GRID_SERV_MON_02(in_cycle_id in number) is
 2 
 3    -- 變量說明
 4       v_file_path    constant varchar2(30):=‘DIR1‘;
 5       v_file_name    varchar2(50);
 6       v_File_Handle  UTL_FILE.FILE_TYPE;
 7       v_line         varchar2
 
(2000);
 8       d_file_name    varchar2(50);
 9 
10 
11       icnt            number(10);
12       v_start_date    varchar(12);
13       v_end_date    varchar(12);
14 
15    -- 日誌變量
16       v_begin_date   date := sysdate;
17       v_step         varchar2(200) := null;
18       con_run        constant number
 
(4) := 9999;
19       v_procedure_id constant number := 37;
20 
21 
22  cursor c_cust_msg  is
23  select
24        BAZ001,
25        BAZ002,
26        BAB221,
27        AAC001,
28        AAB001,
29        AAE002,
30        AAE003,
31        AAE140,
32        BAE060,
33        AAA157,
34        AAA115,
 
35        AAC084,
36        BAE151,
37        AAE180,
38        AAE020,
39        BAE152,
40        to_char(AAB191,‘yyyymmddhh24mi‘) as AAB191,
41        BAE162,
42        BAB222,
43        BAE205,
44        AAE202,
45        BAE181,
46        BAZ003,
47        BAZ004,
48        AAE011,
49        to_char(AAE036,‘yyyymmddhh24mi‘) as AAE036,
50        AAB034,
51        AAA027,
52        BAE513,
53        BAE519
54   from
55       ncsi.ac43 where aae140=‘11‘ and aae002=201802 ;
56 
57   begin
58         v_step:=‘v_step_1‘;
59 
60          d_file_name :=‘ncsi_ac43.dat‘;
61          DBMS_OUTPUT.enable;
62          DBMS_OUTPUT.put(v_file_path);
63          v_step:=‘v_step_1_2‘;
64          v_File_Handle:=UTL_FILE.FOPEN(v_file_path,d_file_name,‘w‘);
65          v_step:=‘v_step_1_3‘;
66 
67          select to_char(sysdate,‘yyyymmddhh24mi‘) into v_start_date from dual;
68         v_step:=‘v_step_2‘;
69 
70          for rec in c_cust_msg loop
71              v_line:=rec.BAZ001||‘,‘||rec.BAZ002||‘,‘||rec.BAB221||‘,‘||rec.AAC001||‘,‘||rec.AAB001||‘,‘||rec.AAE002||‘,‘||rec.AAE003||‘,‘||rec.AAE140||‘,‘||rec.BAE060||‘,‘||rec.AAA157||‘,‘||rec.AAA115||‘,‘||rec.AAC084||‘,‘||rec.BAE151||‘,‘||rec.AAE180||‘,‘||rec.AAE020||‘,‘||rec.BAE152||‘,‘||rec.AAB191||‘,‘||rec.BAE162||‘,‘||rec.BAB222||‘,‘||rec.BAE205||‘,‘||rec.AAE202||‘,‘||rec.BAE181||‘,‘||rec.BAZ003||‘,‘||rec.BAZ004||‘,‘||rec.AAE011||‘,‘||rec.AAE036||‘,‘||rec.AAB034||‘,‘||rec.AAA027||‘,‘||rec.BAE513||‘,‘||rec.BAE519;
72 
73 
74              UTL_FILE.PUT_LINE(v_file_handle,v_line);
75           end loop;
76 
77          UTL_FILE.FCLOSE(v_file_handle);
78 
79 
80 
81   exception when others then
82       rollback;
83   end;

二、創建DIR1目錄

1 create directory DIR1 as ‘/home/oracle/csv‘

三、執行調用存儲過程

1 EXEC Export_GRID_SERV_MON_02(20180102);

ps: 大數據導出時間長，建議創建腳本後臺執行

 1 #!/bin/sh
 2 export PATH
 3 export ORACLE_BASE=/u01/app/oracle
 4 export ORACLE_HOME=$ORACLE_BASE/product/11.2/dbhome_1
 5 export ORACLE_SID=auditdb
 6 LD_LIBRARY_PATH=$ORACLE_HOME/lib
 7 PATH=$PATH:$ORACLE_HOME/bin:$HOME/bin
 8 export ORACLE_BASE ORACLE_HOME ORACLE_SID LD_LIBRARY_PATH
 9 sqlplus "/ as sysdba"<<EOF
10 @pl_ac43.sql
11 EOF
12 
13 [oracle@exchangedb ~]$ more pl_ac43.sql
14 EXEC Export_GRID_SERV_MON_02(20180102);
15 exit
16 
17 nohup ./pl_ac43.sql >> ac43.log &     #執行shell腳本後臺運行
