Currently i got a requirement on finding anomalies b/w two tables in two databases. Both tables represent the same type of data (Product) but there are few feilds in tables which are not common.

1.I want to write a .fex to fine the data in table A and not in table B and vice versa.

There are two common feilds "description" and "Age" in the tables which are not sortable which has to be same, so i need to compare those details too.

The solution in my mind is to merge "Table A" and "Table B" then use a where clause to compare.

if you have come across this situation please advice on a solution.

Regards
G9

Please update your signature first as per link on main page.

Next research MATCH logic using OLD-NOT-NEW etc.

I agree with Tony on using MATCH, but I think you should look into OLD-NOR-NEW. OLD-NOT-NEW will give you the items from the first file that are not in the second, OLD-NOR-NEW will give you the items from either file that don't match.

Pat,

That's why I included the "etc." to imply that there was more to it than just OLD-NOT-NEW, thus encouraging Robing9 to go and look and determine the best method for him / her.

Yep the MATCH condition will tell me whether there is any row mismatch (ie absence of row in any source).

But i also want to match the contents in the row too (ie colomn value in row are same).

First i tried to keep the columns in the sort feild (using "BY") it didn't work since sorting is not possible in text files.

Now i will try to merge those to a single HOLD file the do a where clause 'equal to' between the common fields.


Hope that works.

Robin,

I use a similar process to compare old and new systems to ensure the logic written into the new system is comaprable. This requires comparison at field level so I MATCH the files together OLD-OR-NEW and then define or compute flag fields to identify which fields are not comparable. I exclude those data rows which compare in every field and then by changing the colour of the comparable fields to white and output to EXL2K I can see what the differences are quickly, but still see the underlying data values by selecting all cells as necessary.
