Question

While setting up Sphinx on my production server, this strange error came up when trying to index

ERROR: index 'benefit_core': sql_range_query: You have an error in your SQL 
syntax; check the manual that corresponds to your MySQL server version for the 
right syntax to use near '' at line 1

This doesn’t happen on my local machine. And yes, that is an empty string.

Does anyone seen this type of issue before?

benefit.rb

define_index do 
  # Fields
  indexes category
  indexes title
  indexes tags
  indexes description
  indexes brief_description
  indexes brand
  indexes short_description
  indexes long_description
  indexes benefit_description
  indexes address.city
  indexes address.state
  indexes address.street_1
  where sanitize_sql(["active = true and expiration > ?", Time.now]) 
  set_property :field_weights => {
    :title => 15,
    :tags => 10,
    :brand => 10,
    :description => 3
  }
end

Thinking-Sphinx – 1.4.4

Sphinx – 0.9.9

Thank you!

Answer 1

The problem ended up being with the sanitize_sql method. I replaced that line with:

where "active = true AND expiration > \"#{Time.now.to_formatted_s(:db)}\""

Thanks for the help!
