If the CONTAINS function is not working in Oracle, it may be because the Oracle Text component is not properly installed or there is not a suitable index. To resolve this issue, you can try the following methods:

  1. Make sure that the Oracle Text component is installed correctly. You can refer to the Oracle documentation for the steps to install and configure Oracle Text.
  2. Make sure that a full-text index has been created for the table that requires the use of the CONTAINS function. You can use the CREATE INDEX statement to create a full-text index.
  3. Check whether the columns in the table that contain the CONTAINS function are of text type. The CONTAINS function is commonly used for searching text data.
  4. Make sure you have sufficient permissions to use the CONTAINS function. You may need administrative authority or specific permissions to use this function.

If you are still experiencing issues, it is recommended to refer to Oracle’s official documentation or seek help from Oracle technical support.
