Bug #21080: ALTER VIEW makes user restate SQL SECURITY mode, and ALGORITHM

Browse Source 
When executing ALTER TABLE all the attributes of the view were overwritten.
  This is contrary to the user's expectations.
  So some of the view attributes are preserved now : namely security and 
  algorithm. This means that if they are not specified in ALTER VIEW
  their values are preserved from CREATE VIEW instead of being defaulted.
