I create my own clone http://statoverflow.com/sandbox (using free 10K controls for Telerik users ). I have evidence of the availability of a concept that I can use locally, but before I open it to others, I need to block it a bit more. I am currently running everything through a stored procedure that looks something like this:
CREATE PROCEDURE WebQuery @QueryText nvarchar(1000) AS BEGIN -- no writes, so no need to lock on select SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED -- throttles SET ROWCOUNT 500 SET QUERY_GOVERNOR_COST_LIMIT 500 exec (@QueryText) END
I need to do two more things:
QUERY_GOVERNOR_COST_LIMIT
SET
?
Ad-Hoc SQL? SET, . , , lexx/yacc flex/bison ( CLR) SET. SET @variable=value, SET...
SET @variable=value
