Hi, I have a lot of databases that have the exact same tables and each table has the exact same column structure. I'm looking at merging two of these databases together into a single database (Company A bought Company B and wants the data from A combined into B now). I've been tossing around the idea of looking in database B at each table that would need to be "merged" and simply adding the last ID number to every ID number in database A's tables. For example, in table1 in B's data, the last ID number is 2000, could we simply add 2000 to every ID number in table1 in A's data? Could we then export (SELECT INTO OUTFILE) from A's data and import (LOAD DATA) into B's data? Has anyone done something like this before? Did you have problems? -- ----------------------------- Johnny Withers 601.209.4985 joh...@pixelated.net --- Why not create a view and just concatenate on an identifier? This way the data can be kept in the same forms. Or, if you do want to have it as one table, you can use a select insert statement to move from one to another. Build the select query first to get the data looking like you want it, then convert it when you think you are ready. Of course, backups are your friend in any case. :) Cheers, Craig This e-mail, including any attachments, may be confidential, privileged or otherwise legally protected.
