IF-statement within Load

[#1]

Hi All,

I would like to write an IF-statement within the Load.

If the variable (vDB) is set to the value 1, I want to Load the Field named “Field 1” as “New Field Name”. If vDB is ‘2’, I want to Load the Field named “Field 2” as “New Field Name”.

I tried this:

let vDB = 1;  //vDB = 2;

Table:
Load
if ($(vDB) = 1, "Field 1", "Field 2")as "New Field Name";
SQL Select *
From sourcetable;

…but it doesn’t work correctly.

If I set vDB =1 it works correct and QlikView loads “Field 1” as “New Field Name”.

If I set vDB = 2 QlikView causes an Error.

The Error message is: “Field not found “Field 1”…

Is it possible in QlikView at all?

Please help me out.

Thanks a lot.

Hi Daniel1990,

Try this

let vDB = 1;  //vDB = 2;

Table:
Load
  if ($(vDB) = 1, 'Field 1', 'Field 2')as "New Field Name";
SQL Select *
From sourcetable;

If you want to load a filed NAMED "Field 1", and not loading the value "Field 1", then:

let vDB = 1;  //vDB = 2;

Table:
Load
if ($(vDB) = 1, [Field 1], [Field 2]) as [New Field Name];
SQL Select *
From sourcetable;

Hi,

thanks for the fast answers.

Unfortunately it does not solve the problem.

Maybe i have to add a few supplementations:

With the variable vDB I will load data from two different databases. If it is set to 1 Load from database 1, if it is set to 2 load from database 2.

Now the problem is, that in the table in database 1 the field, i want to load, is named "Field 1" and in database 2 it is named "Field 2".  There is no "Field 1" in database 2 and no "Field 2" in Database 1.

If I try this:

let vDB = 2;  //load from database 2 where "Field 1" not exists

if ($(vDB) = 1, [Field 1], [Field 2]) as [New Field Name];  //now i want to load "Field 2" from the Else-statement

it is the same error. Field not exists. "Field 1"

I would think it is impossible in QlikView.

Thanks a lot for your help.

If the fields are in different databases, then you have to bring them first toghether inside QlikView. After that you can use your IF().

// bring the first field

ODBC Connect to Database1;

Temp_Table:

SELECT [key], [Field 1]

FROM Table1;

// bring the second field

ODBC Connect to Database2;

JOIN (Temp_Table)

SELECT [key], [Field 2]

FROM Table2;

let vDB = 2;  //load from database 2 where "Field 1" not exists

LOAD [key],

            if ($(vDB) = 1, [Field 1], [Field 2]) as [New Field Name]

RESIDENT Temp_Table;
