How to copy value on Dataport Import

selece28

Hi All,
I have a question about Dataport,
How to copy value from one fields to another before import using Dataport
Ex: I have two fields, A and B
First both of the Fields is Empty
On Import using Dataport, i only insert into field A, but before insert, i want to copy the value from field A into field B (i want to use field B to keep previous value of field A)

I use code : A:= B; on before Import but the value is incorrect
How to solve this problem

Thanks in advance

The right place is OnAfterImportRecord

No if i put it OnAfterImportRecord, then field B value will be the same as the field A value

... and what are your dataport fields?

I have 3 fields to import from csv
lets say fields X,Y,A
when i import i want to copy field A value to field B, the insert the csv value into X,Y,A

i also insert a Date type field to keep the update date(workdate)

As I wote before, the right place to fill fields not filled by dataport fields is OnAfterImportRecord trigger. If your field is allready filled, there must be some code to do it (for example in OnValidate trigger in table).

re-read your post. You want to transfer A value to B but you say they both fields are originally blank

Ex: I have two fields, A and B
First both of the Fields is Empty
On Import using Dataport, i only insert into field A, but before insert, i want to copy the value from field A into field B (i want to use field B to keep previous value of field A)

so B should be blank

are you saying that on the second line import you want A to retain it's value from the import of the first line?

now if you can add more detail to your post it would be easier to help you.

Ok here's the example (X is the primary key)

First my table is like this
example:
Column X Y A B D(type = Date)
Value(Blank all)

Then i Import csv to fill falue X,Y,A
example:
Column X, Y, A, B, D(type = Date)
Value 1, 1, 1, (blank because copy from A), 27/02/07(workdate)

Then if i import the next csv to update/insert data
example:
Column X, Y, A, B, D(type = Date)
Value 1, 1, 2, 1(copy from previous value), 27/02/07
Value 2, 3, 3, (blank), 27/02/07
Value 3, 4, 4, (blank), 27/02/07

and so on
So when import, first i copy value A to B, then insert new imported value to A

It seems that you are importing the file with the same primary key. So, can you send me your object and your csv files, I will try to find the problem.

It seems to me that you should do the following

Set a global variable MyRecVar type record the same as the dataitem
you are importing

in the AfterImportRecord section
B := '';
IF MyRecVar.GET(X) THEN
B := MyRecVar.A;

Hope this helps

selece28

yes, all i want to do is copy the A value to B value before insert a new value into A

Could anyone helps ](*,)

In OnBeforeImportRecord trigger (first line):

SaveA := A;

In OnAfterImportRecord trigger:

B := SaveA;

SaveA is a global variable with same type as A and B.
