John, I know the question comes up every once in awhile..and the common agreement is that yes, remedy will pass a 1=0 to the DB.the argument typically occurs around what happens when it hits the DB. Well, from personal experience, I have seen remedy pass a 1=1 to the DB and have that query BLOCK other queries to the table.so in the instance of SQL Server 2005, I guarantee you that it's passed to the DB, and the DB does a table scan.

Specifically - if the qualification on a filter translates to 1=0 -- does the database do a tablescan against the table to see if any records match 1=0 ? I would think that a cheap ARS optimization would be to grab "false" qualifications - and never go to the database at all. This comes up every once in awhile -- and I don't think that ARS would take a qualification where 1=0 and send it to the database for a result list and processing. And -- if ARS does pass 1=0 to the database -- why would that be? -John On Jul 15, 2010, at 6:33 PM, Mueller, Doug wrote: ** John, You cannot. You can have workflow that looks at what is entered in fields and what is entered in the advanced search bar. You cannot however get ahold of the SQL generated. The way the system is constructed is that the qualification comes across the wire as an AR System qualification. That is parsed and processed by the server. There is no workflow on searches at all, but even if there were, the server layers are Receive call and route to a queue Data validation/ access control checking Filters Translation to SQL and issuing command The only layer you would have access is the Filter layer and that occurs before any translation to SQL. There is no way to capture in advance the SQL. You can log SQL statements so you can look at it later, but that is after the fact. You cannot get ahold of the SQL statement in logic.

For example, if in a search form, the user enters search criteria in any fields or the advanced search bar, I would like to capture that query before clicking the search button. Can I use one of the Remedy API's that are already built ? Or are there any other ideas ?
