Chip: "The issue was one or more damaged indexes. After a repair everything seems to be working as it should." Glad you tracked it down quickly.
"Thanks for the insight into QbF, I'll look into it." It's handy. A couple of years ago, just for G&G, I used QbF to support typeahead searching in a system whose primary function is creating proposals, line items, and option items. For each table, the code would QbF over a handful of "high value" fields but it would also find proposals based on values in the line items/option items. The trick was to Seq query destination into local sets and then do set operations as the code iterated. Turned out quite nicely - instantaneous results in a system with 30k ± proposals and about 1MM line items/option items. -- Douglas von Roeder 949-336-2902 On Wed, Oct 3, 2018 at 9:44 AM Chip Scheide <4d_o...@pghrepository.org> wrote: > Thanks Doug, and Arnaud > > The issue was one or more damaged indexes.
