Clob with Base64

I have a clob column in oracle db where i am storing the value in base64 format (which is encoder, which translates image to string format for storing), I want to store the images using liquibase with spring boot

I tried as given below


even though liquibase inserted the value, it is not storing as base64.

FYI : I don’t want to use BLOB, I am using CLOB to store the data in base64
