I was running a rake db:migrate for my rails which failed with the following error:

==  AddColumnsToSavedSearch: migrating ========================================
-- add_column(:saved_searches, :search_param1, :string, {:limit=>1000})
   -> 0.0574s
-- add_column(:saved_searches, :search_param2, :string, {:limit=>1000})
rake aborted!
An error has occurred, all later migrations canceled:

Mysql2::Error: Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. You have to change some columns to TEXT or BLOBs: ALTER TABLE `saved_searches` ADD `search_param2` varchar(1000)

This migration runs fine on my other system which has the same configuration (same OS and DB).

My MySQL DB version is Server version: 5.5.24-0ubuntu0.12.04.1 (Ubuntu).

Any help is appreciated.

Please do let me know if you need any information.

Thanks

    This may not be the issue, but generally the string datatype is used for smaller quantities of text. I believe it uses the VARCHAR(255) type for MySQL. Try changing the datatype to text. There may be some conflict in attempting to limit the columns to a size larger than string can support.
