I have a student database based on student ID. I would like to search the db and delete duplicates. Trying to think this out. Not very experienced. How about this.

Go to field StudentID

Insert !

Find

Now I have all the duplicates

Can I have the script delete every second record?

Thanks for your help in Advance

Hi,

This thread explains the process :

Calcing a field to purge duplicates

Now, as this comes up about 10 times a month, and he surely was getting lazy, Andy uploaded a sample on his Web Site.

Andy Gaunt technique .

Also, the FM 5.0 and 5.5 manual uses this problem as its sample script example. I don't know if it is also in the 6.0 manual.

I am working with andy's FindDuplicates solution. Thanks andy. I have it all set up but am getting all 1s in the Count in last Record field. I can see the duplicates in the other field. Any idea why this is so? I have been working with it for awhile. When I do get 0s can I just delete them?

Thanks in Advance

norm

you need a couple of extra fields

Global_Mark

Flag_to_Delete

Script

Goto Record(first)

Set Field (Global_mark,StudentID)

Loop

Goto Record Next(exit after last)

if(studentid=Global_Mark)

set field (flag to delete,"x")

else

Set field (global_mark,StudentID)

end if

end loop

Make sure you sort your db by studentID before running script. Then just delete all the records that have an x in the flag to delete field
