Case Statement

[#1]

Hi,

Can anyone help re write my case statement please so it works?

proc sql;

create table adjusted_movement as

select *,

case when ltd_allocations gt runnning_sum then 'current' else if ltd_Allocations + weekly_movement gt dealt_amount

then running_sum - ltd_allocations else weekly_movement end as adjusted_movement

from

Allocate_rates_LTD_Allocations;

quit;

Hi,

proc sql;

  create table adjusted_movement as

  select   *,

                case   when ltd_allocations gt runnning_sum then 'current'

                            when ltd_Allocations + weekly_movement gt dealt_amount then running_sum - ltd_allocations

                            else weekly_movement end as adjusted_movement

  from      Allocate_rates_LTD_Allocations;

quit;

I now get this error message?

540  proc sql;

541  create table adjusted_movement as

542  select*,

543  case

544  when ltd_allocations gt running_sum then 'current'

545  when ltd_allocations + weekly_movement gt dealt_amount_ then running_sum - ltd_allocations

546  else weekly_movement end as adjusted_movement

547  from

548  Allocate_rates_LTD_Allocations;

ERROR: Result of WHEN clause 2 is not the same data type as the preceding results.

Yes, thats because the logic of the second when results in a numeric value, the first 'current'.  You need to decide what you want the outcome to be, for instance, if the column is to be text then:

proc sql;

  create table adjusted_movement as

  select   *,

                case   when ltd_allocations gt runnning_sum then 'current'

                            when ltd_Allocations + weekly_movement gt dealt_amount then put(running_sum - ltd_allocations,best.)

                            else put(weekly_movement,best.) end as adjusted_movement

  from      Allocate_rates_LTD_Allocations;

quit;

If its to be numeric then you can't have current, maybe:

proc sql;

  create table adjusted_movement as

  select   *,

                case   when ltd_allocations gt runnning_sum then 99999

                            when ltd_Allocations + weekly_movement gt dealt_amount then running_sum - ltd_allocations

                            else weekly_movement end as adjusted_movement

  from      Allocate_rates_LTD_Allocations;

quit;

Try:

proc sql;

create table adjusted_movement as

select *,

case when ltd_allocations gt runnning_sum then 'current' when ltd_Allocations + weekly_movement gt dealt_amount

then running_sum - ltd_allocations else weekly_movement end as adjusted_movement

from

Allocate_rates_LTD_Allocations;

quit;
