Is it possible to compare 2 encrypted values? If yes, is there any oracle functions are there? or we can compare directly .. For example
col1 and col2 are having encrypted values - can i compare like col1 != col2?

Not just the same algorithm, but algorithm must not use other thing that the data itself and a fixed key to encrypt.
If the encryption of the same data does not lead to the same result each time than you can do nothing.
