I have PHP/PostgreSQL application were i got a search page with some items
to search, am building the search query on server side.
I need to display a paginated search and for this i need to get the total
count of lines matching the search before OFFSET/LIMITing my page, am i
obliged to repeat the query twice ??? first to get the total count, second
to get my page.
it's very heavy
Any one's suggesting better doing ?
