Inner Join Query Not Working Fast In wordpress databse
Hello out there here i am having difficulty in fetching the Brands Per ctegory in the sidebar of my website
Here is the description ..
I am using the feeds and feed uploader to upload feeds and create brands and Product categories in wordpress
The Problem is there is No link Within the Product_category and product_brand and i want too show specific Brands in the
Side bar of a specific category noot the whole brands list which iis going to long down
so i tried out these heavy queries to fetch the brands as per category
but using the INNER JOIN made the databse too slow and the website keeploading without showing brands the query is working fiine the only thing i want to know is to speed up the queries for the Customers so they dont fade up
Hi There Thanx a lot for the reply
The real problem is i dont which indeing you are talking about
i have read several thread about this problem and all are talking about the same thing indexing xan u please explain that how can i use that in my queries please?
This would be something you'd address in the actual database table definition itself, probably most easily done through phpMyAdmin if your web host provides that for your database maintenance. Any table column which is tested in a WHERE, JOIN, or ORDER BY clause should be indexed, either as a simple INDEX, a UNIQUE index, or as the PRIMARY KEY. (And in some instances you may want to create a single index across multiple columns, but for now at least I would not worry about it.
If you bring up your wordpress DB in phpMyAdmin, check each table that is used in your query and check the index setting for each column you use in any of the above SQL sections. If it does not have any index activated, select the "index" option - you probably don't want to use "unique" or "primary" unless you know for sure that's what it should be. Save your changes, then see if that improves performance.
