简单的数据抽取PL/SQL

1、首先建立DIRECTORY 并赋予权限

2、注意PGA的大小 游标 PL/SQL要存放里面 要不要抛错

set serverout on
DECLARE
TYPE emp_table_type IS TABLE OF emp%ROWTYPE
INDEX BY BINARY_INTEGER;
emp_table emp_table_type;
handle UTL_FILE.FILE_TYPE;
start_time  NUMBER(10);
end_time  NUMBER(10);
BEGIN
 start_time:=dbms_utility.get_time;
 SELECT * BULK COLLECT INTO emp_table FROM test;
  FOR i IN 1..emp_table.COUNT LOOP   
   handle:=utl_file.fopen('DIR_DUMP','&OutFile_Name','a');
   utl_file.put_line(handle,'INSERT INTO TEST (ename,job,sal) VALUES ('||chr(39)||emp_table(i).ename||chr(39)||','||chr(39)||emp_table(i).job||chr(39)||','||chr(39)||emp_table(i).sal||chr(39)||')');
   utl_file.fclose(handle);
