Store BigInteger into Mysql

Question

Due to mathematica constraints I've to use the BigInteger class to represent values.

After some calculations I would like to store the result (given by 2x BigInteger instances) into Mysql...

What is the best datatype to store such object ?

I was thinking about using a Blob to store the binary format of those results (128 bits) ? But I would like to avoid unnecessary type conversions.

Answer 1

I would recommend using a Blob and then the BigInteger(byte[] val) constructor to go from byte array to BigInteger, and the BigInteger#toByteArray() method for the other way.
