saving greetings to everyone!
i m receiving a dump data at day 1, inserting all that data into a database. this database has about 30 above tables, each and every table has about 100 above rows. every table has a column name cell id.
on 2nd day i again receive the dump which also has to be inserted into the same database... into their respective tables..
now in any particular table, i have to compare the row of cell id=1 of dump day 1 with the row of cell id=1 of dump day 2.. since the cell ids of any dump could not change, but other fields might be change. so i have to detect this change in other fields of the respective cell id.
can anyone tell me the query of this in SQL please....
