  Fix for bug #19736 VIEW: column names not quoted properly when view is replicated
  
  When we write 'query=...' string to a frm file for views on a slave, 
  indentifiers are not properly quoted due to missing OPTION_QUOTE_SHOW_CREATE 
  flag in the thd->options.
  
  Fix: properly set thd->options for the slave thread.

    Fix for bug #19736 VIEW: column names not quoted properly when view is replicated
      - result adjusted.

  sql/slave.cc@stripped, 2006-11-03 15:27:33+04:00, ramil@stripped +15 -13
    Fix for bug #19736 VIEW: column names not quoted properly when view is replicated
      - properly set thd->options only in one place (in the set_slave_thread_options()),
        using thd_startup_options. As a side effect we have OPTION_BIG_SELECTS flag set
        after the set_slave_thread_options() call from the 
        log_enevt.cc:Rotate_log_event::exec_event().

# This is a BitKeeper patch.  What follows are the unified diffs for the

# that BitKeeper cares about, is below these diffs.
