Hi,
I use Informix in my application. I need to make search case-insensitive (if I look for A I have to find a,Á,Ä,...)
I have two solution:
- I could do a procedure what replace À to A, a to A,... and also create indexes.
- I could have an additional column in the tables with all letters in uppercase and use that columns in the queries
what solution do you think that is the correct?, could the solution 1 have impact in the performance?
Thank in advance
