I know that the % and _ wildcards can be used in conjunction with LIKE to perform powerful queries.
I would like to be able to look for these letters as part of my query though.
For example, If I look for the letter %, then the entry '5%' should be found.

Similarly for the letter _
if I look for _ then it should find the entry 'an underscore is _'

Can anyone tell me how I can escape these special wildcards in my search?
