    How to compare two InfoTable or DataTable Values and find missing value?

    Hello Everyone ;


    In our project there are two DataTable. Both have services which output as InfoTable. We can call them testData and raspiData. Normally this two table must be have equal data. But when it doesnt i want to know which row is missing.


    testData                                                                                                                                                                                                       raspiData

    result data



    My service wont work properly. I dont know where i wrong. It should be list only Barcode "1005" because it isnt in the other table.


    var testData = Things["testDT"].Select();
    var raspiData = Things["RaspiData"].Select();
    var params = {
    infoTableName : "InfoTable",
    dataShapeName : "testDS"
    var result = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape(params);
    var tableLength = testData.rows.length;
    for (var x = 0; x < tableLength; x++) {
    var row = testData.rows[x];
            var tableLength2 = raspiData.rows.length;
                for (var y = 0; y < tableLength2; y++) {
                    var row2 = raspiData.rows[y];
       if(row.Barcode != row2.Barcode){             
    var newEntry = new Object();
                    newEntry.Barcode   = row.Barcode;
                    newEntry.ProdID    = row.ProdID;
                    newEntry.StationID = row.StationID;


    Any help will be appreciated.


    Thank you.
