PHP & MySQL Search Engine

Do you hate sites that do not have a search feature? I do. I think it defeats the purpose of cramming information endlessly in cyberspace. So we want to give a search engine to our users. This sounds really simple, we could try: $search_term_esc = AddSlashes($search_term); $sql = "SELECT * FROM Content WHERE content_bo...

Developer's Checklist: Taking over a project

So I'm starting to get the impression that I no longer tender for brand new projects competing with time and cost in order to win the bids. Recently, more and more people have been asking if I can take over a project that has been abandoned by its developer. I've started writing this article because I find myself forge...

Alternate row background colour in Reporting Services

This is just a note for me as it took a while to find on the net and even then it was confusing as to why it works but it does. Not sure whether you call this an MDX Query or part of a Transact-SQL mashup. You need to go to "Fill" (of each text box in the row - unless there's a faster way) and instead of color, click o...

Merge the content of two similar tables in MySQL

In standard SQL we can combine the contents of two tables with a CROSS JOIN, (BTW these are not instructions to create some table I'll never use again unlike the rest of the solutions I found on the web). In MySQL, I only know how to do this with a UNION ALL clause. Scenario: I have a Joomla module which should take th...

Parameters not being used in report processing

Once again I've spent a whole morning going in the wrong direction with a convincing SQL script. This article is just a note on when using Business Intelligence Development Studio (BIDS) or Report Builder 2.0 and when previewing the report, the parameters are not accounted for (ie. the SQL query creating the dataset do...

Returned a data type that is not valid

Thought I'd put a note on this error. Bearing in mind that this is a general data type error and not just because I tried to convert a date in SQL format to a Month name. An error occurred during local report processing. An error has occurred during report processing. The Group expression used in grouping 'table1_month...
