MYSQL :: Many To Many Matching Query

Matching SQL And Database Query
If I open up phpMyAdmin, click on a database named Gypsy, then click on the SQL tab and paste in the following:

GRANT ALL PRIVILEGES ON Gypsy.* TO 'James_Bond'@'localhost' IDENTIFIED BY î‘'

FLUSH PRIVILEGES;
I know it's at least partially working because I see James_Bond listed among the users when I click on "Privileges" - and I don't see James_Bond listed for any other database.

But when I try the following database connection...

PHP

$link = mysql_connect ("localhost" , "James_Bond", "007") or die(mysql_error());
mysql_select_db ("Gypsy", $link) or die(mysql_error());

I get this error message:

Quote:

Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'James_Bond'@'localhost' (using password: YES) in /Users/MyName/Sites/Geobop/index.php on line 194

Need Help With Matching A Range Of Character In A Query
The following query (modified from original to make it easier for you to
read) select all of the clients whose fisrt initial of their last name
equals a specified character ($lastInitial). It works fine for characters
A-Z but I need to know what to set $lastInitial to for it to select clients
last names that start with a different character than A-Z such as a number
or some kind of punctuation.

select * from Clients
where left(lastName,1) = $lastInitial

Creating A Query That Will Only Return Records With Matching Counterparts
I'm using the table below as an example.

I want to create a MySQL query that will return only records that have matching counter-parts where 'col1' = 'ABC'.

Notice the 'ABC / GHI' record does not have a counter-matching 'GHI / ABC' record. This record should not be returned because there is no matching counter-part. With this table, the 'ABC / GHI' record should be the only one returned in the query.

How can I create a query that will do this?

id | col1 | col2
--------------------
1 | ABC | DEF
2 | DEF | ABC
3 | ABC | GHI
4 | DEF | GHI
5 | GHI | DEF

Matching Results
Suppose you have two tables: A and B. Both tables have the same columns: col1, col2, col3, etc.
So my records are distributed in two different tables that have the same format. I know, this is not good normalization design, but that is the way they are setup right now.
The question is: how do I query both in a single sql statement, combine the results of the query get all the records from both, and list the result in alphabetical order?
I can do:

select * from A ORDER BY status;

and I can also run:

select * from B ORDER BY status;

But how do I run both at the same time and get a single output from them?

Matching Profiles
I am working on a dating website and have to match profiles that are stored in multiple tables. What I am trying to do is to sort results in a descending order starting from best match to the worst, so what I thought of is to use the Levenshtein or similar_text functions on the different values stored in the profile, but later I realized that such an idea would be very time consuming when dealing with thousands records.
Here is an example that shows the structure of my tables:

member[id, login]
look[id_mmeber, weight, hair_color, eyes_color, have_galsses]
pref[id_member, smoke, drink, like_clubbing, like_cafes]
In reality , the profile have more than 3 tables, but 3 will be enough to explain it
So the big question is, is there a way to acheive this by using SQL only ?

Matching Id Numbers
I have a problem with a user management system.
Simply i have 3 tables.

Table 1 - ID1, Name, Pass

Table 2 - ID2, Name, ItemID

Table 3 - ID3, ItemID, ItemName

Let user login using info from table 1, once logged in query table 2 to get all the ItemID's for the logged in user.Once this is done I need to finally query table 3 looking for matches to the itemid's from table 2 in order to show how many orders for each item but only when the itemid is associated with the user from tables 1 and 2.

Matching Strings
I have a lot of records in a table named in this pattern "this text is the same.r01 someText (001/100)", "this text is the same.r01 someText (002/100)", "this text is the same.r02 someText (003/100)" etc.

The idea is that i want to automate the process of recognizing the files belonging to the same file(.r02 in this case), and then set a value which shows that is belongs to a certain fileID in another table.
The problem is that i have no idea what would be the best way to do this. My initial guess is that i would have to use a trigger and a LIKE clause comparing the "this text is the same.r02" part of the string, to see if it already exists in the database. If it does, i have to mark it as belonging to the same file.
I guess using a LIKE clause would be very slow, and the amount of records will grow quite big(millions of rows).

Bitwise Matching
I am using an unsigned INT to store a list of categories for a particular product. Some products can be listed in multiple categories. For example, categories might be 1-Stationery, 2-Furniture, 3-Hardware, etc.

When an item is in multiple categories, i just set the appropriate bit, for example an item that might be listed in stationery and hardware would have bits 1 and 3 set to 1, givng the category a value of 5.

A search then uses a bitwise & to return values based on a user search, for example if a user searches for "stationary and hardware"

Item 1 = 101 (binary)
Search = 101 (binary)
Result = 101 (item1 binary).

What I would like to know is if it's possible to order the results in order of the number of matching bits?

For example 2 items, first with bits 101 set, second with bits 100 set, I would like to return both items, but obviously rank the one with most bits matching the search higher. Is this possible?

Matching Two Tables
I am trying to pull information from two different tables to be displayed in a php file. Both of these tables share the same field of product_id. I need to pull the product name from one table and the location of the image from another table and display them. This is for a store system and I'm randomly trying to show three products on my homepage.

I am just unsure as to how to pull the information. I have code that connects to the DB already and randomly grabs a product name. My next step I am guess is to match the product_id of the name pulled to the other table and get the filename of the image stored in the other table. This is the code I already have.

<?php

$link = mysql_connect("localhost", "tristate_store", "pword") or die (mysql_error ());

mysql_select_db ('tristate_store', $link) or die (mysql_error ());

$desc = mysql_query ("SELECT * FROM `storeproducts_description` ORDER BY RAND() LIMIT 0,1") or die (mysql_error ());

$res = mysql_fetch_assoc ($desc);

echo ''. $res['products_name'] . ' Click here ' . $res['products_id'];

?>

Pattern Matching?
I have some data I want to pull out of one field and put into another. The tricky part is that the field the data is in is a text field, and the data could be anywhere in there. So I need to do some sort of pattern matching to find it.

Here is an example of the query I want to run, but I don't know what to put for the question mark.

UPDATE Building SET architect = ? WHERE description LIKE '%Architect: %';

In the description field, architects are in this format:

Architect: name of architect
or
Architect: name of architect, http://example.com/

The name of the architect may contain commas.

So the pattern match needs to do this:

Find "Architect: "
then find ", http://" or "
" or end of field after that
take the text in between and put it in the architect field.

Matching Escaped Strings
I have the following info in my database

ID|Name
================
1|Author's

As you can see, the name value has been escaped. Now, the question is, how do you match on a value that has escaped charaters? I've tried the following

SELECT * FROM table WHERE Name = 'Author's'

SELECT * FROM table WHERE Name LIKE 'Author's'
SELECT * FROM table WHERE Name = '%Author's%'
SELECT * FROM table WHERE Name = 'Author''s'
SELECT * FROM table WHERE Name = "Author's"
SELECT * FROM table WHERE Name = "Author's"

And none of them work.

Mysql String Matching
I have string in a field like theses: rel-1-0, rel-2-0, rel-3-0,
rel-21-0.

If comparing them in this way:
select 'rel-3-0'>'rel-21-0';

Mysql will return "1" as true, this is false in our knowledge.
I wonder if there is a way to order such string inside mysql so that

rel-3-0 < rel-21-0?

String Matching Across 2 Tables
I have 2 tables.

Table 1 has 2 columns; address (varchar), ID (int)
Table 2 has 1 column; town_name (varchar)

table1.address is a string which contains a town_name. I want to produce a query result that has each address matched up to the correct town_name.
Ideally i would extract the town name directly from the address string but the position of the town name in the address string is impossible to specify.

Matching Multiple Rows
I've got the following tables with the following columns:

property: id, address, number_of_bedrooms
attribute: id, title (e.g. washing machine, central heating, furnished)
property_attribute: property, attribute (composite primary key on both id columns)

what i'm trying to do is select property ids that have all the attributes i'm looking for, for example, all those properties that have a washing machine and are furnished.

I've been trying things like the following which aren't working, probably because the attribute column won't be equal to two different values at once.

SELECT pa.property FROM property_attribute AS pa INNER JOIN attribute AS a ON pa.attribute=a.id WHERE a.title='washing machine' AND a.title='furnished'

this is returning an empty set because, i think, a.title can't have two values at once. what i want to say in pseudo-sql is:

SELECT pa.property FROM property_attribute AS pa INNER JOIN attribute AS a ON pa.attribute=a.id WHERE
(pa.property=X AND a.title='washing machine') AND (pa.property=X AND a.title='furnished')

so the only results that will be returned are where a property has both attributes.

i can't think of how to do this since there will be varying numbers of attributes i need to search on. perhaps i need to use a variable for pa.property - i tried that, setting it to SELECT DISTINCT property FROM property_attribute, but mysql didn't like it because this query returned multiple rows. i may need some kind of set variable or an array.

RE Table Name Matching Function
how one would go about specifying a table name in a select statement where the table name is also the name of a function. I know it's poor database design, but unfortunately it's the way it was made many years ago. The table name is "year" and of course, there is a function called "year".

I tried single and double quotes, but that doesn't seem to work I tried searching the documentation, but I haven't found anything.

Limit On Matching Results Only?
Is there a way to do a limit with a starting and ending value that works like a:

LIMIT 10, 20

only it pulls the 10 resulting rows that matched the where clause of the query vs. just showing the 10 rows regardless of the where clause?

Example:

select product_name from products where product_count > 0 limit $start, $end;

The desired result is that the query returns however many rows fall between the value of $start and $end, lets say 10 rows, but the 10 rows returned are the first 10 rows that matched the where clause of the query and not just the next 10 rows of the table.

Output Only Displays Matching Value
I have two tables, Table1 and Table2. When i submit a name from my form ( eg : jimmy ), 'jimmy' is inserted into both tables. Now this part is fine. In the output, it displays the data from both tables ( output: jimmy - jimmy )
The problem i am having lies in my sql statement i believe.
Basically, the way i have it now, it says, if 'jimmy' is in Table1 AND in Table2, output the results, otherwise forget it!
It does not output anything if 'jimmy' is in NOT in Table1 but IS in Table2, or vice versa.

My code :

$result = mysql_query("SELECT".
"`TABLE1`.username,".
"`TABLE2`.username ".
FROM".
"`TABLE1`,".
"`TABLE2`".
"WHERE".
"`TABLE1`.username = `TABLE2`.username ".
"") or die(mysql_error());

Matching Keyword Lists
I have a table with 2 fields: aid and keyword.

aid stands for an article and keyword is a keyword in that article. Each article has of course multiple keywords (+/- 200).

What I'm trying to do is find out which articles have the most keywords in common. I have found a way to do this, but am afraid this will explode once I have a substantial amount of articles:

Code:
SELECT aid, count(*) as r FROM `articleKeywords` WHERE keyword IN (SELECT keyword FROM articleKeywords WHERE aid = 1) AND aid != 1 GROUP BY aid ORDER BY r DESC
Is this the right way or are there better ways to do this?

the problem is that sometimes, because of user input, there will be no matching fields in the tables orders_styles or styles (no rows with matching orders_id exists in table orders_styles to table orders). I still want to show these rows however. Right now, as you can see it only displays rows that have matching rows in orders_styles and styles.

how do i make it so it will match each word as well as the entire string?
