武澄清 释原论
夫练太极拳者须知阴阳，辨识虚实明，然后知进退，固是进中有退，退仍是进，退中隐有进机，此中须有转合，身法要有虚领顶劲，拔背含胸，气沉丹田，裹裆护肫，精神总要提起，则周身旋转自如，两手支撑八面，活似车轮，所向无敌，人劲方来，未能发出， 我既打去，此谓打闷劲，人劲已来，我早静待，着身即便打去，此谓打来劲，人已落空，欲将换劲，我随之打去，此谓打回劲，由此体验，留心揣摩，自然从心所欲阶及神明矣。
武汝清 结论
夫拳名太极者，阴阳，虚实也，阴阳明，然后知进退，进固是进，进中有退，退步仍是进，退中隐有进机，此中转关，在于身法，虚领顶劲，含胸拔背，则精神提得起，气沉丹田，而裹裆护臀，则周转便捷，肘宜曲，曲而能伸，伸则支撑得势；膝宜曲蓄，蓄而后发，则发劲有力，至与人交手，手先着力，只听人劲，务要由人，不要由己，务要知人，不要使人知己，知人由上下 前后 左右自能引进落空，则人背我顺，此中转关，在于松肩，主宰于腰，立根在脚，但听命于心，一动无有不动，一静无有不静，上下一气，既所谓立如枰准，活似车轮，支撑八面，所向无敌， 人劲将来，未能发出，我既打去，谓之打闷劲，人劲已动，我早静待，着身便打去，所谓打来劲， 人劲已落空，将欲换劲，我随打去，此谓打回劲。由此体验，留心揣摩，自能从心所欲，阶及神明焉。
武禹襄 打手要言
彼不动，己不动，彼微动，己先动，以己依人，务要知己，乃能随转随接，以己粘人，必须知人，乃能不后不先，精神能提得起，则无迟重之虞，粘依能跟得灵，方见落空之妙，往复须分阴阳，进退须有转合，机由己发，力从人借，发劲须上下相随，乃能一往无敌，立身须中正不偏，方能八面支撑。

郭厚福论三劲
打闷劲实质既打彼意动，这种手法，非听劲特别灵敏 静中寓动动犹静的准备十分充分是作不到的，打闷劲最为省力，或略加化劲，或直接击之，皆易成功。
打来劲的时机不得有分毫差迟，非对来劲称量的十分准确不可，此以静待动之法，不须引进，彼自送上门来，所难者认定准头也。
打回劲是太极拳引进落空合既出的典型技法，又叫顺势借力，切忌用硬力，也不宜用把抓捋，欲打彼回劲，既要把恰当的分寸无过无不及，要退中隐有进机，否则容易走空丢手，甚至反为人制。
此中奥秘，只在灵心。
且心一虚，则全体皆虚，惟虚则灵，灵足以应敌。
敌人图我之意时，先已了然于胸。察敌之所注，与吾身相触之灵觉，敌方意向，我无不知，我得而从之制也。
微风也能顺化，叶落亦能知警，登此门堂，许为初成。

installation of PHP

0. download the zip file and unzip it into c:php

1. add the PHP directory to PATH

2. Copy php.ini-recommended to php.ini

3. Added the following lines httpd.conf in Apache directory

# For PHP 5 do something like this:
LoadModule php5_module "c:/php/php5apache2.dll"
AddType application/x-httpd-php .php

# configure the path to php.ini
PHPIniDir "C:/php"

Done

reverse() reverses a single byte string but it does not work well with multi-byte characters

SQL> select reverse('abc') from dual;
REVERS
------
cba

SQL> exec :mystr := '国中cba';
1 SELECT max(replace(SYS_CONNECT_BY_PATH (c, '/'), '/')) keep (dense_rank last order by level)
2 FROM (SELECT LEVEL lvl, SUBSTR (:mystr, LEVEL, 1) c
3 FROM (SELECT LENGTH (:mystr) len
4 FROM DUAL) x
5 CONNECT BY LEVEL <= x.len
6 ORDER BY 1 DESC)
7* CONNECT BY PRIOR lvl = lvl + 1

MAX(REPLACE(SYS_CONNECT_BY_PATH(C,'/'),'/'))KEEP(DENSE_RANKLASTORDERBYLEVEL)

You do not need to have DBA priviledge to view all the database parameters

A simple script will do

set serveroutput on size 1000000

declare
x number;
y long;
d number;
begin
if ( dbms_utility.get_parameter_value( '&1', x, y ) = 1 )
then
dbms_output.put_line( y );
else
dbms_output.put_line( x );
end if;
end;

Unfortunately, the following parameters are not supported

shared_pool_size
sga_max_size
shared_pool_reserved_size
large_pool_size
java_pool_size
db_keep_cache_size
db_recycle_cache_size
db_2k_cache_size

SQL> select * from tst;

C1 C2 C3
---------- ---------- ----------
1 150
1 1 80
1 2 90
1 1 130
1 3 120

Make sum on C2 based on group (c1, c2), the special requirement is
within the group of (1, null), it should include 10% of the sum of
other groups which c2 is not null. To achive this, one row will go
to 2 groups. one for itself and one maps to (c1, null).

The query will be

select
C1,
(CASE WHEN TYPE = 1 THEN C2
WHEN TYPE = 2 THEN NULL
END) C2,
SUM(CASE WHEN TYPE = 1 THEN C3
WHEN TYPE = 2 AND C2 IS NOT NULL THEN C3*0.1
ELSE NULL
END) C3_SUM
from
(
select c1, c2, sum(c3) c3
from tst
group by c1, c2
), (select 1 type from dual union all select 2 type from dual
)
group by
C1,
(CASE WHEN TYPE = 1 THEN C2
WHEN TYPE = 2 THEN NULL
END)

and result is

C1 C2 C3_SUM
---------- ---------- ----------
1 192
1 1 210
1 2 90
1 3 120

In the load control file, you can specify a filler column so that it will be skipped.

SQL> desc dept
Name
-----------------
DEPTNO
DNAME
LOC

Control File

LOAD DATA
INFILE *
INTO TABLE dept
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
(x filler integer, dname, loc)
BEGINDATA
12,RESEARCH,"SARATOGA"
10,"ACCOUNTING",CLEVELAND

It will allow you only load value for column dname and loc. The first column ID will be skipped.

意拳的"肩撑肘横" = 太极拳的掤=孙存周说的“里撑外裹”

沉肩坠肘和肩撑肘横是阴阳互根

刚刚脱却冬装，一抬头却已是满街樱花的烂漫。
如雪 在风中飘落。

故乡的杏花想必也是春意满枝了吧
