If-else statement in LOAD

Tue, 17 Nov 2009 18:21:50 GMT

Hi,

i'm trying to to create if-else in LOAD in script level.

LOAD
ID,
(A+B+C) as F1;
SQL SELECT *
FROM TABLE

the if-else would be placed at the calculation,

column F1 = if (a+b+c) > 20 then set F1 as DIGIT 1 else 0 so that i can use it to count.

Column F2 = if (a+b+c) < 20 then set F2 as DIGIT 1 else 0....

so in the end, i'd have 3 column, ID, F1, F2

Try the following


LOAD
ID,
IF(A+B+C > 20 , 1 , 0) AS F1,
IF(A+B+C < 20 , 1, 0) AS F2;
SQL SELECT * FROM TABLE;

Thanks for the solution, it works for me.

But it wont work if i'm using the new name after the AS

Load
Field1 as Fieldtext
if (Fieldtext = abc, .........

i had to use...Field1 instead of Fieldtext. any idea why?

Load
Field1 as Fieldtext
if (Field1 = abc, .........

the reason is that Field1 could be a very long formula or IF ELSE statment, so it'd be good if i can just use Fieldtext as a substitute..

If FieldName is a long field or a formula you can replace it by a variable such as

LET MyFieldName='LongFieldNameBlablabla';

Thenin your Load

LOAD

IF("$(MyFieldName)" = abc, ....) then it should work.

You can stack LOAD statements like this:

tablename:
LOAD Field3;
LOAD if(Field2 = 'def', ...) as Field3;
LOAD if(Field1 = 'abc', ...) as Field2 FROM....;
