get value from rows

below snippet will help you out. first get the datatableentry by key

iterate that to get value

now create infotable structure according to other datatable

set values to infotable entry and use adddatatableentry

**********************************************************************************

// result: INFOTABLE dataShape: ""
var result1 = me.GetDataTableEntryByKey({
key: "GMP" /* STRING */
});
var params = {
infoTableName : "InfoTable",
dataShapeName : "newOtherDS"
};

// CreateInfoTableFromDataShape(infoTableName:STRING("InfoTable"), dataShapeName:STRING):INFOTABLE(newOtherDS)
var result2 = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape(params);

var tableLength = result1.rows.length;
for (var x=0; x < tableLength; x++) {
var row = result1.rows[x];

var value = row.value; // NUMBER

// newOtherDS entry object
var newEntry = new Object();
newEntry.name = "new entry"; // STRING
newEntry.value = value; // NUMBER [Primary Key]
result2.AddRow(newEntry);
// id: STRING
var id = Things["otherDataTable"].AddDataTableEntry({
sourceType: undefined /* STRING */,
values: result2 /* INFOTABLE */,
location: undefined /* LOCATION */,
source: undefined /* STRING */,
tags: undefined /* TAGS */
});

}

// communityDS entry object
