hi list,
this is one of these faq-questions (for sql queries) nowhere found. normally
two tables are
joined by two singular keys, for instance "id" which is (1) in both tables.
But how do I join them over a id-field like this:(1,2,4)? I know, there is
the WHERE id IN(...) function, but if I do a:
But now I think it's the only way.

Hi list,
A nut to crack:
I have a medium-sized database(about 1000 rows). The keys contain
zip-address-information. Now I want to get the surrounding persons, e.g.
someone has zip 12345 I would get(now for 4 entries):
+---+--+
| 12340 | personA |
| 12345 | personB | <-- I searched
nary-sorted-Trees or Tries. Do you
have any short description of this for me?
Thanks a lot,
Jan Peuker

Good evening List,
I have a problem on my fulltext-search. If I create the sample table from
MySQL-Doc it runs perfect.
If I create my own - it doesn't. I can't say more: Here is my dump:
CREATE TABLE tcl (id int(10) primary key not null, description varchar(254),
date timestamp, value int(11),
Uhm, 3?
Didn't you wrote 5?
If you want just 3 do this: SELECT name,date FROM dates ORDER BY date LIMIT
0,3
regars,
Jan

Hi Sabine (again ;-) )
I suppose you already tried this:
http://www.mysql.com/doc/N/T/NT_start.html
This could be problems w/ your path or your my.ini (overwritten my
mysqladmin).
If it won't start anyway, put mysqladmin.exe to your autostart.
regards, (Grüße)

Here is another question;-)
Is there any ability to put tables dynamic in a query?
I have to do a select * for many tables and it would be cool if I just do
something like this
select * from (select t from mytables).
Thanks a lot,
Jan

Hi Alec,
thanks for this answer.
a) My column is not involved by query
b) But it is necessary to hold it in the database (and I don't want to set
file_priv)
c) And it's as long as a whole document, this means 5-10K
I think, a Primary Key is as good as an Index. I will use one table for
every type
That's the point: Users are added about 10 times less than "objects". But
your objection about new columns is right, also about system performance. I
would have said the main problem is on a query like "show all users with
their last object" for an overview, this would be a very hard job (I think
My first two questions could not be answered, so, maybe I'll be luck w/
third.
A performance question: If I have user numbers and "objects" belonging to
them(e.g.bills), is it better to have one table "bills" with many rows or to
have one table for every user? This means, is it better to do a sql
You have to update your seession-path in your php.ini (usually located in
%%systemroot%% eg windows) to a valid windows-path like c:\windows\temp

Short question: Is there a way to update SET-options without alter table?
e.g. if one user is registered in table1 he is allowed(means registered in
set-row options) to write his id into table2 ?
Thanks,
Jan
P.S.: For the filter: I want to do a sql query which does something.

I never saw the function "date()", to insert current date use:
CURRENT_DATE();

Subject: SELECT the first lette
Hi List,
I am using MySQL MAX 3.23 on a SuSE Linux System. But my problem is about
SQL:
Is there a "in the near of my result" statement that returns the surrounding
rows, e.g. SELECT name FROM names WHERE name="foo" NEAR(-2,2) which results:
ann marie foo bar john?
I know, if my keys would be inc
A timestamp-datatype automatically updates itself with the current date if
the row has changed, so, in this case timestamp is not the preferred
datatype. As far as i know, in MySQL Procedures are just for output,
Triggers are not implemented...Only method would be to insert this field
using insert
