==== TO_CHAR ====
<code sql>
       to_char(cnt_response / cnt_target * 100 ,'999,999,990.99')as rate_response
</code>
==== Alter Table ====
<code sql>
alter table supp_pfr add  grp_qty number(6,0);
comment ON COLUMN saled.reg_kind IS '세일등록구분';
</code>
==== Index ====
<code sql>
create UNIQUE INDEX AK_PEE_RATER_TARGET ON PEE_RATER_TARGET (APPR_ID, RATEE_EMP_NO)
</code>
==== ORA_ROWSCN ====
<code sql>
SELECT ORA_ROWSCN, last_name FROM employees WHERE employee_id = 188;

SELECT SCN_TO_TIMESTAMP(ORA_ROWSCN), last_name FROM employees
   WHERE employee_id = 188;
</code>
==== Error Log Table ====
Data Bulk Processing 시 유용한 방법인듯 싶으니 참고하세요..

<code sql>
-- Error Log Table 생성
declare 
  -- Local variables here
  i integer;
begin
  -- Test statements here
  DBMS_ERRLOG.CREATE_ERROR_LOG('ZZZ', 'ZZZ_ERRLOG');
end;



-- 적용 예
insert into zzz
  (nm)
SELECT '1' from dual
UNION ALL
SELECT '12345678901' from dual
LOG ERRORS INTO  zzz_errlog(select userenv('sessionid') from dual) REJECT LIMIT UNLIMITED;

</code>

==== RAISE_APPLICATION_ERROR ====
20000~20999까지의 에러 숫자는 비워져 있다. 이 에러 숫자에 사용자 정의 오류 메시지를 실행 시킬 수 있다. 

<code sql>
RAISE_APPLICATION_ERROR(-20001, 'asdf Error Message');
</code>
==== UTL_RAW ====
charset이 상이한 I/F에서 사용하여 한글 Encoding문제해결
**utl_row.cast_to_raw <=> utl_row.cast_to_varchar2**

<code sql>
UTL_RAW.CAST_FROM_BINARY_DOUBLE (n,endian) RETURN RAW;
UTL_RAW.CAST_FROM_BINARY_FLOAT (n, endian) RETURN RAW;
UTL_RAW.CAST_FROM_BINARY_INTEGER(n, endian) RETURN RAW;
UTL_RAW.CAST_FROM_NUMBER (n) RETURN RAW;
UTL_RAW.CAST_TO _BINARY_DOUBLE (n,endian) RETURN BINARY_DOUBLE;
UTL_RAW.CAST_TO _BINARY_FLOAT (n, endian) RETURN BINARY_FLOAT;
UTL_RAW.CAST_TO _BINARY_INTEGER(n, endian) RETURN BINARY_INTEGER;
UTL_RAW.CAST_TO _NUMBER (n) RETURN NUMBER;
UTL_RAW.CAST_TO_RAW (data) RETURN RAW;
UTL_RAW.CAST_TO_VARCHAR2 (r) RETURN VARCHAR;
</code>
==== Table Comments ====
<code sql>
SELECT A.TABLE_NAME, B.COMMENTS
  FROM ALL_TABLES A, ALL_TAB_COMMENTS B
 WHERE A.TABLE_NAME = B.TABLE_NAME
   AND A.TABLE_NAME LIKE 'LEM_COURSE%'
 ORDER BY A.TABLE_NAME;
