Im trying to model the EBNF expression
("declare" "namespace" ";")* ("declare" "variable" ";")*
I have built up the yacc (Im using MPPG) grammar, which seems to represent this, but it fails to match my test expression.
The test case i'm trying to match...

It seems that you need a 2-token lookahead in this situation .
It's been a long time since I've used anything yacc-like, but here are a couple of suggestions that may or may not help .

Derby doesn't support this syntax:

Have you tried:
UPDATE x SET (col1)= ( SELECT a FROM y where y.fkfield = x.pkidfield), (col21)= ( SELECT b FROM y where y.fkfield = x.pkidfield), ).

I was looking for a way to do a BITOR() with an Oracle database and came across a suggestion to just use BITAND() instead, replacing BITOR(a,b) with a + b - BITAND(a,b).
I tested it by hand a few times and verified it seems to work for all binary numbers...

This applet let you play with polynomial y=f(x)=a*x 3 +b*x 2 +c*x+d
You can drag two points x1,x2 along the function.
It will calculate the integral between x1 and x2, the slope at those two points will be shown if you enable the checkbox.

Alright, let's say I have these two tables:

If I understood your problem correctly, ....
SELECT stuff FROM Items as i INNER JOIN item_properties as ip ON i.id = ip.item_id WHERE ip.prop_id IN (123, 456) AND ip.prop_id NOT IN (789, 101)
It's NOT TESTED, but that the kind of thing I tend to do a lot .

ご回答大変有難うございます。
はい。
:
片方がφになればfは単射という事になります。
片方ともφにならないなら,∀a∈Aに対してb∈Bが唯一つ決めれた事になるのでこの時のfも単射となります。
はい。
AもBも可算の場合はAもBもN(:自然数全体)に対等だから
∃f:A→N:全単射, ∃g:N→B:全単射だから
gf:A→B:単射が採れお仕舞い。
Aが非可算でBが可算の場合は#A=アレフ1,#B=アレフ0で
AはR(:実数全体)に対等だから∃f:R→A:全単射,
BはN(:自然数全体...

A×B の部分集合 C....
A の部分集合 A' と B の部分集合 B' との間の
全単射は, 積集合 A×B のある部分集合 C のことだと
考えられます.
そうですが,
これは意味不明.
そんでは役に立ちません.
A が実数全体との間に全単射がある集合で,
B が自然数全体との間に全単射がある集合であれば,
確かに正しいですが, そんな遣り方で, 任意の集合
同士の場合を証明するには日が暮れます.
