I have found the answer in another thread, and it works nicely.
@Select(class\object) IN @Prompt(‘Select blah’,‘A’,class\object’,multi,free) or (’*’ IN @Prompt(‘Select blah’,‘A’,‘class\object’,multi,free))
However, is there a way to actually include the ‘*’ in the LOV dropdown? Webi has a funny prompt in that the values remain static unless you move to another field. I know this sounds silly, but the users can be so lazy that they can’t be bothered to tab to the next field… they’ve actually been discussing this in a meeting!
Another alternative is to create a separate object with a constant ‘ALL’ (associated with the DUAL table), and use that object in a union query in the LOV. You can also reference that same object via @Select in the pre-defined conditions. Same exact result, but I generally dislike overriding SQL. Plus, if you ever need to change ‘ALL’ to say ‘*’ you only have to change it in one place.
Omkar, the question was not how to use “all”, but how to include that (the “all”) in the list of values to be selected. Your solution is similar to the Designer FAQ but does not provide for the ALL or * to show up in the list to be selected.
