Re: Question on Data Structures

The answer to the question as asked is yes. But if you create the array as Dim(*Auto: .... ) you don't need to set it.

Here's an example:

Dcl-Ds results ExtName('ANIMALS') qualified Dim( *Auto : 1000 ); End-Ds;

Dcl-Ds animal likeDs(results);

Dcl-s type like(results.type);

Exec SQL
Declare animalsCursor cursor for
Select * from ANIMALS where type = :type;

Exec SQL
Open animalsCursor;

Exec SQL
Fetch from animalsCursor for 1000 rows into :results;

Dsply ( 'Found ' + %Char( %Elem( results ) ) + ' matching animals' );

For-Each animal in results;
Dsply ( 'Id: ' + %Char(animal.Id) + ' - Name: ' + animal.name );
EndFor;

Exec SQL
Close animalsCursor;

In fact you don't even need to reset the element count before the next select - the SQL preprocessor seems to do that for you.

Is it possible to dynamically set the number of OCCURRENCES "DIM(##)" on a
dynamically created Data Structure?

dcl-ds EmpFile_ds extname('EMPPF')
qualified dim(10) ;

What I am wanting to do is load the contents of a SQL CURSOR which could be
1 to N something. Taking the number of rows in the CURSOR to dynamically
create the Data Structure.
