Use SQL wild card keywords when searching a table column that may have more than word entered

Hey guys, I am trying to create a search bar for my site, I have a products column that has the name of the products, my search query is working but I need to enter the full product name to find it, here is my query:

$query = "SELECT * FROM PRODUCTS WHERE CATALOGUEID = (SELECT CATALOGUEID FROM PRODUCT_CATALOGUE WHERE PRODUCT_NAME LIKE '%" . $term. "%') AND category1 = 1  ";

Open in new window


The variable $term is the keyword passed to the query, I will sanitise the query once I get it working. If I want to search for a product called Cyclone Jacket, I need to enter "Cyclone Jacket" into the search bar, is it possible to set up the wildcard keyword to search for simply "Jacket"?

It is highly unlikely someone will be searching for a product by its full name but rather words such as jacket, shirt, trousers etc...

If anyone could help me figure this out that would be great!

Many thanks!

The query which you had written was almost fine. However, I had changed it lil bit:

$query = "SELECT * FROM PRODUCTS WHERE CATALOGUEID in (SELECT CATALOGUEID FROM PRODUCT_CATALOGUE WHERE PRODUCT_NAME LIKE '%" . $term. "%') AND category1 = 1  ";

My article on Complex Text Filters covers this, but was written with Access in mind.  You would need to take a look at the function described there and convert it to a SQL Server UDF.

Have you looked into SQL Server Full Text Indexing?  This would give you the ability to use the FREETEXT command in SQL Server that will probably meet your needs.  

If you haven't done any research on Full Text Indexing, you'll have do do a little bit of reading, but it's worth it.  Results are incredibly faster and more reliable then using LIKE '%' statements in your WHERE clause.

IT Pros Agree: AI and Machine Learning Key

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

This might make a difference. Do not concatenate the statement, let the php server parse it itself. (ie no full stops around the variable)

$query = "SELECT * FROM PRODUCTS 
		  WHERE CATALOGUEID = 
		  	(SELECT CATALOGUEID 
		  	 FROM PRODUCT_CATALOGUE 
		  	 WHERE PRODUCT_NAME LIKE '%$term%') 
		  AND category1 = 1  ";

Thanks for all your input guys. I have read all your posts and am trying my best to make the most of your advice. Munterman I tried your suggestion but it returned an error when searching for the word vest, instead of the whole name which is Ultracool Aero Vest:

vestError in query preparation/execution.

Subquery error. Replace the = with IN

$query = "SELECT * FROM PRODUCTS 
		  WHERE CATALOGUEID IN
		  	(SELECT CATALOGUEID 
		  	 FROM PRODUCT_CATALOGUE 
		  	 WHERE PRODUCT_NAME LIKE '%$term%') 
		  AND category1 = 1  ";
