I have data in various tables with this structure:

I need to combine the tables into this structure:
Time_Stamp
ValueFromTable1
ValueFromTable2
ValueFromTable3
You could normalise the table a bit more so you end up with a structure
like this:
TableName
Time_Stamp
Value
Then you can run SQL like this (untested):
INSERT INTO MyLogTable;
FIELDS (Tablename, Time_Stamp, Value) ;
SELECT "Table1", Time_Stamp, Value ;
FROM Table1;
UNION ALL ;
SELECT "Table2", Time_Stamp, Value ;
FROM Table2;
UNION ALL ;
SELECT "Table3", Time_Stamp, Value ;
FROM Table3
otherwise, something along the lines of Peter's suggestion should work.
