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:<\/p>\n

    \n
  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.<\/li>\n
  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.<\/li>\n
  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.<\/li>\n
  4. Make sure you have sufficient permissions to use the CONTAINS function. You may need administrative authority or specific permissions to use this function.<\/li>\n<\/ol>\n

    If you are still experiencing issues, it is recommended to refer to Oracle’s official documentation or seek help from Oracle technical support.<\/p>\n","protected":false},"excerpt":{"rendered":"
