Question

I have two schemas S1 and S2 with identical table structure. I`ll start with example:

on S1.table1 I have:

    ID   DATA1       DATA2
   ---- ---------- ---------- 
    01   data1       test1
    02   data1       test1

on S2.table1 I have:

     ID   DATA1       DATA2
   ---- ---------- ---------- 
    01   data2       test2
    02   data2       test2

Is it possible to select one row (from S1.table1) update it (change value of ID column) and insert it into S2.table1? I want to write single SQL query which will be used as prepared statement (Java).

Final result on S2 should be:

     ID   DATA1       DATA2
   ---- ---------- ---------- 
    01   data2       test2
    02   data2       test2
    03   data1       test1

so i inserted first row from S1.table1, and changed only ID.

Thanks,
Jonas

How about

INSERT INTO S2
SELECT 03, DATA1, DATA2 FROM S1 WHERE ID=01

That is, you just select the data you want, but explicitly indicate any replacement data.
