NI Datafinder Toolkit

[GaneshkumarN]

I need to develop a small application to evaluate TDMS file system. I can write data in to TDMS file format. But i am getting problem when i try to read from TDMS file. All basic read query woks fine for TDMS file using NI datafinder Toolkit. I need to implement "SQL WHERE clause" equivalent in LabVIEW for TDMS file using NI dataFinder. Please let me know how to implement SQL equivalent query using NI Datafinder Toolkit.

Please have a look at the DataFinder_ExecuteQuery.vi and DataFinder_Pass_Fail_Analysis.vi example (e.g. by using Example Finder: Toolkits and Modules - DataFinder).

This is like "SQL on the wire". Please feel free to ask in case of additional questions.

Hi,

TDMS Write VI not updating Minimum and Maximum values automatically

Thanks

For performance reason LabVIEW does not calculate Minimum/Maximum when storing TDMS files
