Data fletching

Fri, 04 Sep 2015 08:17:13 GMT

Hi Community,

I have few tables and need to fletch some columns only,

Ex:

Tables:

COLLATERAL

CONTRACT_GUARANTEE

ENTITY

FACILITY

And columns are

ex:

From table: COLLATERAL - columns are: Dim1, Dim2, Dim3.

From table: CONTRACT_GUARANTEE- columns are: XDim1, XDim2, XDim3.

Like that.

Generally we can flethc the data then we can remove unwanted data.. but here I am looking for any simple methat or new one by using some functions.

I have multiple tables that is why I am asking.

This is what you need if I understand from you question correct:

Load

Dim1,

Dim2,

Dim3

from COLLATARAL ...... ;

Load

XDim1,

from CONTRACT_GUARANTEE .....;

etc.

I presume you mean fetch instead of fletch. You might want to look up what fletching actually is

The best idea is to specify the columns you do want to extract. That way you don't load unnecessary data in the first place. If you're lazy and don't care about extra network traffic and storage volumes you can load all the data and drop fields afterwards using the DROP FIELD instruction.

so why don't you load only the required columns?

Collateral:

Load Dim1,

Dim2,
Dim3

from Collateral...

Contract_Guarantee:

Load

XDim1,

XDim2,

XDim3

from Contract_Guarantee...

THat what you want?
