Product not exists - add manual values zero

I have table

table1:

LOAD * INLINE [

month,rep,sales,product

Jan ,101,3000,p1

Jan,102,2340,p1

Jan,103,2450,p2

Jan,103,1200,p1

Jan,101,1211,p2

Jan,103,1111,p2

feb,102,5000,p1

feb,103,4000,p2

feb,102,2000,p3

feb,103,6543,p1

March,101,2310,p1

March,103,1200,p2

];

Rep 101 does not sell anything on month of Feb.

I have a list of products

p1,p2,p3,p4,p5

I want to add the product p1,p2,p3,p4,p5 value 0 for feb for Rep 101 and

March rep 101 already has sold product p1 -but I want to add p2,p3,p4,p5 for sales 0 for March.

I have millions of records. Looping will kill my performance  for comparing the products.

Please advice is there any better way to handle this situations.

Re: Product not exists - add manual values zero

We should verify  the performance:

tab:

LOAD * INLINE [

month,rep,sales,product

Jan ,101,3000,p1

Jan,102,2340,p1

Jan,103,2450,p2

Jan,103,1200,p1

Jan,101,1211,p2

Jan,103,1111,p2

feb,102,5000,p1

feb,103,4000,p2

feb,102,2000,p3

feb,103,6543,p1

March,101,2310,p1

March,103,1200,p2

];

// a table with all months, all products, all reps

t:

     load Distinct month Resident tab;

join load Distinct rep   Resident tab;

join load Distinct product Resident tab;

Concatenate(tab)

load *, 0 as sales Resident t;

drop Table t;

Re: Product not exists - add manual values zero

Are you sure you need all these 0's?  See how a pivot table may look like just with your sample data, zeroes are there:

Re: Product not exists - add manual values zero

This should work in a load script:

table1:

LOAD

   AutoNumber( month & '|' & product & '|' & rep ) AS %Key,

   *

INLINE [

month,rep,sales,product

Jan ,101,3000,p1

Jan,102,2340,p1

Jan,103,2450,p2

Jan,103,1200,p1

Jan,101,1211,p2

Jan,103,1111,p2

feb,102,5000,p1

feb,103,4000,p2

feb,102,2000,p3

feb,103,6543,p1

March,101,2310,p1

March,103,1200,p2

];

Products:

LOAD DISTINCT

  product

RESIDENT

  table1;

Months:

LOAD DISTINCT

  month

RESIDENT

  table1;

Reps:

LOAD DISTINCT

    rep

RESIDENT

    table1;

   

nProds = NoOfRows('Products');

nMonths = NoOfRows('Months');

nReps = NoOfRows('Reps');

LOAD

  *

WHERE Not( Exists( %Key ));

LOAD

  AutoNumber(month & '|' & product & '|' & Peek(rep,IterNo()-1,'Reps')) AS %Key,

  month,

  product,

  Peek(rep,IterNo()-1,'Reps') AS rep,

  0 AS sales

WHILE IterNo()<=$(nReps);

LOAD

  month,

  Peek(product,IterNo()-1,'Products') AS product

WHILE IterNo()<=$(nProds);   

LOAD

  Peek(month,RecNo()-1,'Months') AS month

AUTOGENERATE

  $(nMonths);

// IF NOT NEEDED DROP THE HELPER TABLES...

DROP TABLES Products, Months, Reps;

Re: Product not exists - add manual values zero

One more version, rather simple script additions, no loops, to make dimension selections mutually independent, so you can see more 0's

that's how it should be done
