</div>Hi Jayesh,<br>
Thanks for the analysis.<br>
<br>
As I found no C/C++ API for HSQL, JDBC is needed to connect [1].<br>
Then, there's information_schema support in HSQL [2].<br>
<br>
Then, part of the research is to connect the code that reads the db<br>
with C/C++, without intermediate files, and ideally without extra<br>
processes.<br>
