I read a while back that MySQL will only use one index per query. (If this
is not so, please tell me and point me to a doc that gives a good
explanation of MySQL's current index usage policy). I'm using MySQL 4.2.x.
Here's my dilemma.

Hiya
I have a DataTable containing thousands of records. Each record has a
primary key field called "ID" and another field called "PRODUCT" I want to
retrieve the rows that satisy the following criteria:
I have a list of about 100 numbers which correspond to the ID field and also
another 40 say numbers corresponding to the numbers in the PRODUCT field. I
want to show the rows that correspond to both these criteria.

What would be the fastest way to search 18,000 strings of an average size of
10Kb, I can have all the strings in memory, should I simply do a instr on
all of the strings? Or is there a faster way? I would like to have a kind of
search like google where you can enter several words to search for, guess
that calls for a regular expression "word1|word2|word3|...".
Is there any kind of indexing tools available for this kind of thing, I have

In my form I have a master table and a details table linked 1xM. I can
search through the whole parent table but I also like to be able to search
through the child table fields to find parent records. Should I design a new
form for this or can I somehow make this work in the same form.
Thanks in advance,

Hi
I have a binary file which contains records sorted by Identifiers
which are strings. The Identifiers are stored in ascending order. I
would have to write a routine to give the record given the Identifier.
The logical way would be to read the record once and put it in an STL
container such as vector and then use lower_bound to search for a
given identifier. But for some strange reason i'm asked to not use a
container but instead...

Greetings and salutations. I have developed an A2K3 MDB and have a
search form modeled after Allen Browne's search form (http://
allenbrowne.com/ser-62.html). It works well except for records which
have multiple related records in 1:many relationships and many:to:many
relationships. To view my results, I created a query called qryAllData
which contains all of the data from several tables for each record.
For example, say I have one...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
