In Oracle, CONTAINS is a function used for full-text searching to check whether a text column contains specified keywords or phrases. The CONTAINS function is typically used in queries involving full-text search indexes.

The basic syntax of the CONTAINS function is as follows:

CONTAINS(column_name, 'search_text', 1) > 0
  1. column_name: Specify the name of the text column to search.
  2. ‘search_text’: specifies the keyword or phrase to be searched.
  3. Specifying search criteria, usually indicated by 1 for conducting a full-text search.

When the result returned by the CONTAINS function is greater than 0, it means that the column_name column contains the search_text keyword or phrase. Further filtering and processing can be done according to the actual situation.
