I'm a little fuzzy on how to create an autocomplete parameter. If I'm understanding the documentation correctly I'd put the following code into my autocomplete parameter (obviously using my table/column info and accounting for mysql/mssql differences):
create procedure sp_Autoc_DBR_Titles( inTitle varchar(255) )
where Title like concat( inTitle, '%');
But that doesn't work. Maybe adding a screenshot or two to the documentation (similar to the screenshots explaining the other parameter types) may help clear things up for me.
