Question

I have a table

id / product_id / var / active / price

the var column contains three variables separated by :

e.g. (37:48:80)

i want to change the price column to a set value if var contains the right options.

i.e.

33:38:57 through to 80 would = 450 
33:39:57 through to 80 would = 0 
33:40:57 through to 80 would = 0 
33:41:57 through to 80 would = 450 

i would like to pass the first variable an array of the second variable and if matched update price

my very bad sql would look like:

   UPDATE 'price' = 450 
   WHERE 'var' = 33:array(38,41 etc):array(57,58 etc)

i know thats really wrong but thought may help you understand what I’m trying to do.

Answer 1

I don’t quite get the through to 80 but I get the idea of your query (I guess…). I kinda hate regular expressions but they seem to be the right tool to solve this. Give this a try:

update t set price = 450
where var regexp '^33:(38|41):(57|58)$'
