Hi! For my thesis (diploma) i have to implement an extension of derby. I would like to implement a further CREATE-statement for the production of data samples. Thus for example the instruction "CREATE SAMPLE ON TABLE x" should create a sample of the data from table x. Furthermore I would like to create a new Catalog-Table like SYSSAMPLES. I added the new Tokens i need to the existing parser, which creates the associate querytree. My problem is, where and how this querytree is to be executed. I tried to follow the way of execution of a normal create-table-statement, but i couldn´t understand it. There are so many functions/classes etc., that i don´tknow where to look. Could someone give me a hint or explain the structure of derby´s execution part? I would be grateful also for an overview of the general structure of derby. Thanx a lot! Bye, Anja
