My favorite physical activity is table tennis, which also happens to be the
world's best brain sport. It is highly aerobic and gets both the upper and
lower body moving in every which way — twisting, bending down low, reaching
up high, and shuffling from side to side. Plus, it gives your brain one
heckuva workout.
Also known as "ping-pong," the game is great for hand-eye coordination and
reflexes (cerebellum and parietal lobes). You have to focus (prefrontal

是什么关系。通过看每个table的constraints和dependecy，可以看到一个table的所有
FK都是reference哪个table的。我目前知道的在Oracle Sql Developer或Sq Server
management studio里都可以这样看到，但是只能一个table一个table的看。我想肯定
有一个tool，可以把这很多个table的关系自动生成一个ERD表，比如Table A的PK跟
Table B的FK自动连起来。请问Sql developer或sql server里都可以做吗？多谢了！ |

上中下三策。
上中已经被你排除了。
now, you need some serious codings and configurations to do.
idea 1) use temp table.
basically, you wanna create a view, including the report table and at least
a temp table.
when people do insert, always insert to the empty temp table first.
then you will get the row count, if the row count is small,
then insert/update it to the report table, if big, danamically create a new
temp table,
and include the 3 table into the view, so the table list in the view grows,

ALTER TABLE的话，那你这个SP就很外行了，原则是不让你改TABLE，你弄个TEMP TABLE
，RANK完一个放进去，TABLENAME也做成个COLUMN,然后RANK第二个再放进去，最后一次

会出错，这种做法也很不专业。 |
