hi there,

i test different databases, so far there are mysql, postgresql and mongoDB.
I wrote an insert method that I can use for all three databases.
But until now I didn't find any way to write a function that reads all existing data from a table/collection with all three databases.
so far I used hibernate search and that just worked for mongoDB.

does anybody know an example code or some hints to write that generic query?

Thanks in advance :)
