Retrieve Citadel Data via ODBC SQL produces a crash in the nilxtcor.dll file if the query is executed several times (appx 1000). The amount of data requested varies the crash point. Wondering if anyone has seen this behavior. We saw this problem in 2011 and NI produced a fix. Also the query test runs 5-10x faster in 2012DSC vs 2013DSC.
Our test:
We tried extracting 1 to 10 numeric variables over a 5 min span with a 10sec interval.
OS: Tried Windows 7 32 and 64bit
Applications: Standalone VB.Net exe, Labview Development mode or Labview standalone exe produces same result
Example of Query:
SELECT IntData.LocalTime,
IntData."GRF-WKS225/OsmoseHist/tank1Volume"
FROM IntData IntData
WHERE IntData.IntInterval = ' 00:10'
AND IntData.LocalTime > ' 2014-05-14 13:30:00'
AND IntData.LocalTime <= ' 2014-05-14 13:35:00'"
