Case Insensitive Like Searches In MySQL
I needed to create a query that did a case insensitive search using the LIKE command in MySQL and I quickly realised that in order to do this I would need to alter both the parameter and the table data to be the same case. This can be done by using the MySQL UPPER() command on the table data and the strtoupper() PHP function on the input data.

Count Number Of Characters In A String With MySQL
Today I needed to grab some data from a table where there was more than one occurrence of a string within another string. Basically, I needed to find all URL's from a table that were more than 3 levels deep (i.e. with 3 slashes), but realised there wasn't a function to do this in MySQL.

Nice solution. Thanks!
Later on, I found an alternative solution using the bitwise XOR operator (^). I think I prefer that solution as it also works if the field is signed.
example: UPDATE table SET field = 1 ^ field
