$select in table

Mon Mar 20 16:35:20 UTC 2023

hi Andy..

you are right….   and there is always a ‘yes but’…. :)

me, I replace all the punctuation like ‘, $,&, (), * “ ! etc., escape codes, and spaces in a search tag anyway with a ‘%’

that way searching for O’Brien or OBrien will find it, regardless of the quote. (the search is ‘%O%Brien%’) 

or searching for ‘Andy Hilton’ will find you regardless if you have a middle name. (the search is ‘%Andy%Hilton%’

searhcing for Bob! will find ‘bob’ since the ! is ignored.    

that way you can use partial words for any search and strip away stuff known to hide characters.

bind vars are less useful if you want that kind of searching since you have to replace text and add functions like unaccent()
