    PI SDK - IPISubBatches2 search function parameters

    jngai

      Hello,

      When mining PI Batch DB data in MATLAB, I can typically locate the information I need by drilling down to the appropriate UnitBatch/SubBatch level and looking for particular unique items (PIUnitBatches.Item('stringA').PISubBatches.Item('stringB').PISubBatches.Item('stringC').

      However, for those instances when multiple occurences of a particular SubBatch or phase are present, the Item function still only pulls the first occurrence in the list, and not an array of all occurrences.

           - Typically, when this is known, a for-loop is employed to search through the list.

       

      I know there is a IPISubBatches2 search function --> Search = handle Search(handle, string, Variant(Optional))

      Does anyone know what the search parameters are, and whether this would be applicable in terms of a more efficient data mining process?

       

      Thanks in advance,

      Jerry
