ALTER_TEXT_SEARCH_DICTIONARY - change the definition of a text search dictionary

There is no ALTERTEXTSEARCHDICTIONARY statement in the SQL standard.

ALTERTEXTSEARCHDICTIONARY changes the definition of a text search dictionary. You can change the dictionary's template-specific options, or change the dictionary's name or owner. You must be the owner of the dictionary to use ALTERTEXTSEARCHDICTIONARY.

The following example command changes the stopword list for a Snowball-based dictionary. Other parameters remain unchanged. ALTER TEXT SEARCH DICTIONARY my_dict ( StopWords = newrussian ); The following example command changes the language option to dutch, and removes the stopword option entirely. ALTER TEXT SEARCH DICTIONARY my_dict ( language = dutch, StopWords ); The following example command “updates” the dictionary's definition without actually changing anything. ALTER TEXT SEARCH DICTIONARY my_dict ( dummy ); (The reason this works is that the option removal code doesn't complain if there is no such option.) This trick is useful when changing configuration files for the dictionary: the ALTER will force existing database sessions to re-read the configuration files, which otherwise they would never do if they had read them earlier.
