When using function TRIMV('T', SUPC_CDLOK, 6, ' ', 1, 'A6V'), I get a correct translation/aggregation to SQL

When using function TRIMV('L', SUPC_CDLOK, 6, ' ', 1, 'A6V'), I get an error FOC2576 - COMBINATION OF PARAMETERS OF TRIMV CANNOT BE CONVERTED TO SQL
(same thing for option 'B')

Considering I'm connecting to Oracle where the same TRIM function is present, I'm failing to understand why the function isn't getting translated...

Am I missing something?

Try using the native SQL function instead:

SQL.TRIM(...)

I'm not sure where this is documented but it seems like a great new feature.

From the Summary of New Features, v7.7.03:
quote:
SQL.Function Syntax for Direct DBMS Function Calls

The SQL adapters support SQL scalar functions in a request. The function must be row based and have a parameter list that consists of a comma-delimited list of columns, constants, or expressions. In order to reference the function in a request, prefix the function name with SQL.
Though there's no mention of which functions are allowed...

Hi Francis,

I did start using SQL functions in response to a suggestion from JAlbarrán to a previous post of mine.

However, there seem to be some drawbacks when combining several functions in a single define...

That being said, the part I don't understand is why I need to resort to using SQL-functions when the WebFocus functions seem 100% compatible?

(Similarly, I am using SQL.TO_NUMBER instead of EDIT because EDIT refuses to translate to SQL...)

Peter,

Yes, the Oracle TRIM function does the same type of trimming, leading | trailing | both, so WebFOCUS should be able to translate the TRIMV.

In the past, I know that using AV fields has been tricky - the V functions are fairly recent.

This is when I'd open a case...
