I think our original problem with bind variables had something to do with inserts on very large (column wise) tables and overwhelming the SQL buffer... That's the area which is foremost in my mind when we address the effect of generally changing the use of Bind Variables. I am asking support for more information on that - and best ways to test and trap the issue.
Its interesting that there is a fair amount of comment in the MS SQL forum about the Rich text > Plain text translation issue with some exotic stored procedures. I can already tell you the current PB rich text format is different from the current one and Rich text doesn't export to excel very well - so we either need to come up with an "on-the-fly" database solution for reporting of rich text or simultaneously store plain text and rich text with the data.
I guess this should be its own forum topic.
