renaming a specific value when loading the data

Tue, 12 Oct 2010 10:19:56 GMT

Hello all,

I have the problem below:

I am loading two different tables where the same value is written differently

( eg on the first table is called Client_A and on the 2nd is called ClientA)

is there any way to write on the loading script that wheneever meets value ClientA to rename it to Client_A?

Regards,

Savvas

Hello Savvas,

To rename one field in the loading process do the following

LOAD Client_A, Field2;SQL SELECT Client_A Field2FROM Database.Table; LOAD ClientA AS Client_A, Field3;SQL SELECT ClientA, Field3FROM Database.Table2;

Hope that helps

You need to write the following mapping statement just before the first load statement in your script:

MAPPING:

MAPPING LOAD * inline [

Old ,New

ClientA, Client_A];

map [FieldName] using MAPPING;

Just replace [FieldName] with the actual FieldName in your script. Remember to write the above script before your normal load statement.

This way you can replace not only one but more records.

hmm I think I was not clear enough. I dont want to rename a field but I want to rename a certain value within the field.

for example I have a field in both tables called Customer. In this field on the 1st table I have the values Client_A, Client_B etc..

on the 2nd table I have tha values ClientA, ClientB etc... and when I join them in Qlikview this creates a problem since Qlikview cannot understand that Client_A=ClientA.

so what I was thinking is if I could rename the values ( not the name of the fields) while loading them in the system. if you want I can post two excel files with samples of my two tables.

thanks again!

Mapping load will rename the values and not field names. I have suggested this assuming that you have a particular field say X and values are Client_A and Client(A).
