I am practicing on Restful Apis. I can use Get and Post methods. However, I couldn’t use the Delete method. I added the If-Match parameter to the header. I tried “*” as the value, I tried with etag value. I couldn’t solve the problem. The error message is “ORA-20100: Error.ODATA_TO_PLSQL_PROTOCOL: ETag must have a valid value, was

  • ” How can I delete a record?

     

    Example

    Projection: main/ifsapplications/projection/v1/EmployeesHandling.svc

     

    I can Post gender.

    I can Get the gender.

    I can’t Delete the gender.

     

    • For the etag, make sure you remove the \ character in the actual string, as this is used to handle the “ in JSON.

     

    For example, take the following etag from a Get request.

    "@odata.etag": "W/\"Vy8iOTBDODc5RTQ4NzkxNDZCQkIyRkU5RTQ3M0U3RUU2NUI6MjAyMDA2MjUwOTA3MTQi\""

     

    The actual etag string to use in the If-Match header parameter.

    W/"Vy8iOTBDODc5RTQ4NzkxNDZCQkIyRkU5RTQ3M0U3RUU2NUI6MjAyMDA2MjUwOTA3MTQi"

    That is perfect. Very smartly. Thank you @Technical Outlaws . I wasn’t thinking of “\” as an escape character. Is it written in the technical documentation?
