Thanks for the quick reply. I got it using this:
def search_SQL_database(sku)
posts = @tbl.where(:"product code/sku" => sku)
dataset = posts.map(:"product code/sku")
var1 = dataset[0]
if var1 == sku
puts "The SKU #{sku} was found in the database"
else
puts "#{sku} was not found in the database"
end
end
