hello my friend, yes you are right.. I saw now..
well, i understood that the main problem is that both databases has a column named "id" that is incremental, and when i merge them, the ID column has duplicates, and when i try to see them on our software, duplicates are ignored, so basically i see only the main table, like I didnt merged the second one..
is there any way to merge those tables and change the incremental "id" field for the new records? i mean, if table 1 has 1000 entries, and table 2 has 200 entries, i would like table 3 to have 1200 entries each one with a unique valeu in the id field, did you understand me???? thanks in advance as ALWAYS...
