Retrieve fields with similar values from 2 tables?

[no.mail.pls]

Hiya,

How do i retreive fields with similar values from 2 tables?

I tried to use
(1) "SELECT * FROM $table1 as o , $table2 as p WHERE o.name like
'%p.name%'";
but it retrieves nothing at all.

(2) "SELECT * FROM $table1 as o , $table2 as p WHERE o.name like p.name";
will retrieve exact matches only, but this is not what i want.

(3) SELECT * FROM $table1 as o , $table2 as p WHERE o.name LIKE CONCAT('%',
p.name, '%');
will retrieve exact matches only.

Any advice will be appreciated.

PostScript: i posted the above in mysql groups, but problem remains, so am
trying my luck here.

TIA

[Erwin Moller]

Hi,

I never saw LIKE used in that way ever before, and am unsure if that is
possible.
I only used/saw LIKE with a literal string, not a dynamic construct, like
yours, joined on another table.
I would advise you to dive into the documentation for your version of mysql,
to first check if it is allowed anyway.

If it is not allowed: solve the problem programmaticall y. Get the table into
your scriptingenviro nment and solve the join in there.

But once again: I could be completely wrong, and maybe it IS possible in
mysql.

You've also asked this in (at least) comp.databases. mysql and
alt.comp.databa ses.mysql (where is is much more appropriate).

And please learn how to cross-post.

I would probably do something like in PHP:

select name from table2;

in a while loop

I would probably do something like in PHP:

psuedo-code:


select name from table2;
while values
select * from table1 where name like '%$table2name%'
do more stuff... with second result set...

Unless you have a name that contains the string 'p.name', literally,
you won't.

I don't see why not.

Granted, it may not be done that way very often, but it's possible.

I have used:
... WHERE '$email' like whitelist.patte rn;

on occasion in email filtering applications. pattern might contain
something like '%@mycustomer.c om' or '%@%.mycompany. com'. It's not
real efficient (MySQL probably has to do a patternmatch on every
row, especially if the leading character in the pattern is a %, as
it often is. But it works. And it may be much easier to use
patterns than to use lots more fixed strings and separate tables
for host, user@host, user, etc.

Also possible is:

... WHERE normalize('$ema il') like normalize(white list.pattern);

where the normalize() function converts to lower case, removes leading
and trailing spaces, removes comments, etc. This one is also likely
difficult to optimize. normalize() would either be implemented with
stored procs or be expanded inline with calls to a bunch of other
SQL functions.

Hiya,

Thanks for all replies.

The following solution posted by Jake works like a charm.

"Jake Krohn" <krohnk@ece.cmu .edu> wrote in message
news:dvehtp$5se $1@nntp.ece.cmu .edu...[color=blue]

> Jake Krohn[/color]

The doc from mysql.com has this to say:
INSTR(str,subst r)

Returns the position of the first occurrence of substring substr in string
str. This is the same as the two-argument form of LOCATE(), except that the
order of the arguments is reversed.

mysql> SELECT INSTR('foobarba r', 'bar');
-> 4
mysql> SELECT INSTR('xbar', 'foobar');
-> 0
This function is multi-byte safe. In MySQL 3.23, this function is case
sensitive. For 4.0 on, it is case sensitive only if either argument is a
binary string.

cheers.

Pethaps to x-post or not is a choice between the devil and the deep blue
sea, even though not all of us believe in devils, and some of us love the
deep blue sea.

Tiptoeing gently among the mines in Usenet can be a tricky bizness.

And people who want answers should follow usenet conventions - which
includes cross-posting instead of multi-posting.

Perhaps it is more accurate to say that it includes, as well as excludes,
x-posting. Sell not the devil short.

Only in your book does it include multi-posting to multiple newsgroups.

If you want the help, follow the conventions. Otherwise soon you won't
be able to get any responses to any of your questions.

Remember - we're all volunteers here. None of us are being paid to help
you. And we don't have to.

Appreciate if you can show me the convention that multi-posting is not
allowed, bearing in mind that i first asked in one newsgroup, and failing to
get a solution, i asked in another.

If what you claimed as convention is true, then i should never ask the same
question again in another newsgroup, even though there is no solution from
the first group i posted in.

And if x-posting is allowed, then i should post a question in all relevant
newsgroups simultaneously.

Is the above true?

cheers

Hi,

Allow me to drop in here.
Jerry was only warning you that multiposting can work against you.
If I see the same question in more newsgroups I follow, I almost never
answer because I don't know where to answer, and am unsure if the poster is
checking them all. Even if I perfectly well know how to help.

So you can ask for conventions and such, but that won't help. You can find
1000 opinionson how to behave on usenet.

Bottomline is that many do not appreciate multipost, and in the end it will
work against you.

(Just ment as a kind word of advise)

You should pick and choose the most likely group(s) where your question could be
asked. Then cross-post to those groups. Typically you should post to at most
three or four groups; if you need to post to more generally your question is too
broad (you haven't identified the problem yet) or you're posting to
inappropriate groups.

Once you have posted - wait at least 24 to 48 hours for a response. If you
haven't gotten a response by that time, chances are your question was not clear
or was not appropriate to those newsgroups. Seldom have I ever seen a message
go longer than that (at least in busy newsgroups) not be responded to in that time.
