SQL parameter for multisource tree

Hi,

We need to have the selection parameters like following to get a multisourcetree with multiple selections (check boxes in trees structure).

  

WHERE ( COUNTRY EQ &country_sel.(OR(FIND COUNTRY IN CAR)).COUNTRY:. );
WHERE ( CAR EQ &car_sel.(OR(FIND CAR IN CAR)).CAR:. );
WHERE ( MODEL EQ &model_sel.(OR(FIND MODEL IN CAR)).CAR:. );


Any idea how these will be in an SQL query? When I have IN() in SQL, WebFOCUS is not recoconizing it has a multiple OR/AND and I am unable to get checkboxes in the tree control. It is appearing as radio buttons in tree with single select. I am using App Studio.

Thanks for any help.

Regards,
Cyril Joy.

Hi Cyril,

It seems you want multi-select, but from SQL PASSTHRU.

The syntax for using the IN keyword is as follows:
 
SELECT column_name 
FROM derived_table 
WHERE column_name [NOT] IN ('value1', 'value2', ... ,'value_n')

This SQL statement will return the records where column1 is value1, value2..., or value_n. The number of values in the parenthesis can be one or more, and they can be numerical or characters.

So, using multi-select, you would probably want a delimiter of ',' (comma), rather than 'OR'.

A comma is allowed as a delimiter, but it doesn’t quote the values.

So, you'll need to use OR, and use STRREP to replace ' OR ' with ',' 
(<space>OR<space> with comma)
in the result.

Cheers!

Kathryn

No, When we use 'IN' in SQL query, WebFOCUS will not create a tree with a checkbox for the GUI selection.

WF is not identifying 'IN' inside SQL Query as a parameter to create a multisource tree with checkbox for GUI selection.
