Mysql from 2 tables

Mysql from 2 tables

Hi,
I wonder if someone could assist. I am trying to bring the order of presentation from one table and present the information on the page using the order in another table where the common factor in both tables is the url.

I have tried the following (and could be miles off track) and am getting a syntax error

mysql_select_db($database_menuConn, $menuConn);
$query_rsCatsSubsProd = "SELECT Pageurl, Heading, ShortContentLeftPanel, ShortContent, Category, SubCategory FROM pages WHERE Category LIKE '%Adhesion%' AND SubCategory LIKE '%Pull Off Adhesion Tester%'
INNER JOIN productssubcategory ON productssubcategory.url = pages.Pageurl
ORDER BY productssubcategory.myorder ASC";

Any help would be greatly appreciated!!

i dont see an error in your syntax, do you get the syntax error when testing the recordset? or when viewing the page in the browser?

have tried running thee query directly in PHPMyAdmin or another MySQL GUI Tool? i find it helpful to use a GUI tool for getting the syntax correct before creating the recordset in DW.

see this page for details on the syntax for a join query:
sql_join_inner.asp

Hi Jason, I get it when I test the page

have you tried testing the recordset in the recordset window?

have you tried the query in the MySQL GUI Tool?

if you can test the recordset in the recordset window, then the syntax error is coming from something else on the page.

This is the error message:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'INNER JOIN productssubcategory ON productssubcategory.url = pages.Pageurl ORDER ' at line 2

ahh, right, i see. (Including the full error text is a definite plus)


the problem is that the inner join is after the where.

the inner join needs to come before the where clause, not after.

Jason, I tested it by running the query in navicat and it seems to run just fine. That was before your last post.

The query I ran was :

SELECT Pageurl, Heading, ShortContentLeftPanel, ShortContent, Category, SubCategory FROM pages WHERE Category LIKE '%Adhesion%' AND SubCategory LIKE '%Pull Off Adhesion Tester%';
INNER JOIN productssubcategory ON productssubcategory.url = pages.Pageurl ORDER BY productssubcategory.myorder ASC";

Not sure what to do re your last post. Would you be kind enough to give me an example based on the above so that the inner join comes before the where clause as you suggested???

many thanks Jason

well, in your SQL, you have:
FROM pages WHERE Category LIKE '%Adhesion%' AND SubCategory LIKE '%Pull Off Adhesion Tester%';
INNER JOIN productssubcategory ON productssubcategory.url = pages.Pageurl


First you have the From section:
FROM pages

followed by the where clause:
WHERE Category LIKE '%Adhesion%' AND SubCategory LIKE '%Pull Off Adhesion Tester%';


followed by the inner join clause:
INNER JOIN productssubcategory ON productssubcategory.url = pages.Pageurl


actually looking at the code for the where clause separately, there is a semi colon at the end that should not be there

instead of having the where clause code before the inner join, it should come after the Inner join



SELECT Pageurl, Heading, ShortContentLeftPanel, ShortContent, Category, SubCategory FROM pages
INNER JOIN productssubcategory ON productssubcategory.url = pages.Pageurl
WHERE Category LIKE '%Adhesion%' AND SubCategory LIKE '%Pull Off Adhesion Tester%'
ORDER BY productssubcategory.myorder ASC"

Hi Jason,
I am still getting a problem. if I test the following query in navicat :

SELECT * FROM pages
INNER JOIN productsubcategory ON productsubcategory.url = pages.Pageurl
WHERE Category LIKE '%Adhesion%' AND SubCategory LIKE '%Pull Off Adhesion Tester%'
ORDER BY productsubcategory.myorder ASC"

I get the following error message:

[SQL] SELECT * FROM pages
INNER JOIN productsubcategory ON productsubcategory.url = pages.Pageurl
WHERE Category LIKE '%Adhesion%' AND SubCategory LIKE '%Pull Off Adhesion Tester%'
ORDER BY productsubcategory.myorder ASC"

[Err] 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '"' at line 4
..

In addition, please see attached the DW Test.


If I run the page in a browser with the following query:

mysql_select_db($database_menuConn, $menuConn);
$query_rsCatsSubsProd = "SELECT * FROM pages INNER JOIN productsubcategory ON productsubcategory.url = pages.Pageurl WHERE Category LIKE '%Adhesion%' AND SubCategory LIKE '%Pull Off Adhesion Tester%' ORDER BY productsubcategory.myorder ASC";


I get this message in the browser:

Illegal mix of collations (latin1_general_ci,IMPLICIT) and (latin1_swedish_ci,IMPLICIT) for operation '='

So I am now lost at sea!!

Can you see what I am doing wrong?

Your assistance is MUCH appreciated

your query:
SELECT * FROM pages
INNER JOIN productsubcategory ON productsubcategory.url = pages.Pageurl
WHERE Category LIKE '%Adhesion%' AND SubCategory LIKE '%Pull Off Adhesion Tester%'
ORDER BY productsubcategory.myorder ASC"

shouldnt have the quotes at the end.


the error:
Illegal mix of collations (latin1_general_ci,IMPLICIT) and (latin1_swedish_ci,IMPLICIT) for operation '='

is saying that the collation for the productsubcategory.url column and the pages.Pageurl column do not match.
