How to implement this program for importing into a table without using the INSERT INTO SELECT Statement?

Question

Currently the import/insert process is working perfectly. But I don\'t want to write a single query for both inserting and selecting but rather write a separate query for select

Answer 1

You can (and should) include the concept-id-selecting query within an IN clause:

INSERT INTO snomedinfo_data (refid, id, effectivetime, active, moduleid, conceptid, 
                             languagecode, typeid, term, caseSignificanceid) 
    SELECT refid, id, effectivetime, active, moduleid, conceptid, 
                    languagecode, typeid, term, caseSignificanceid 
           FROM snomed_descriptiondata 
           WHERE active = 1 AND conceptid IN 
               (SELECT cd.id FROM snomed_conceptdata cd WHERE cd.active = 1)

This way you should be able to do everything in one statement which will be orders of magnitude faster than processing the same data row-by-row (a.k.a slow-by-slow) by the JDBC driver.
