Hi Chris, We'll in all honesty, I think it's best for me to provide a brief summary.
We need to remove our dependency upon and use of the healthmarketscience sqlbuilder libary. Used very little in SqlStore class [0]. The problem I ran into when looking into this was that unfortunately JOOQ doesn't support data definition language constructs which is exactly what we require. Although this is in the pipeline (for JOOQ), I have a feeling that it may be some way off. I did however run into a couple of examples of implementing similar functionality to what we require, unfortunately I got distracted and haven't had time to go back to it. I have included all of my resources on the offending issue on our Jira so anyone trying to pick it up would really be starting off from where I got to. This is the blocking issue here and unfortunately it doesn't look like something legal guys can help out with, it simply a case of understanding exactly what functionality we require then finding a replacement and someone that can code it in using a more suitably licensed library. If it is for the sake of pushing out with a Gora 0.2 release as per your requirement's E.g. archive gora-sql then I would probably back this for the time being... I am not using the gora-sql module, and in all honesty I don't think that many others are hence the level of interest to get this module up to scratch! I began a thread a week or so ago, and to be honest the gora-sql issue was the only blocked in my opinion. Thanks for chiming in on this one.
