You can write and run javascript commands (and scripts in ,js files) allowing you to code iteratation over a dataset (querydb), alter the data (in a csv for example) and automate region creation and various other commands.

The command is

>jint

to switch into javascript coding mode.

You can write a js file and execute using the file path parameter

> jint "pathtofile/file.js"

Here is a sample script that queries a "customers" table for any customers that have a flag set and then for each of those it creates a data island "region" and pushes up the customers "orders" to an island.

var result = di.connect("youraccount","yourpassword");

var table = di.querydb("select top 2 * from customers where hasregionflag='Y'");

for(var x=0;x<table.Rows.Count;x++)

{

   var fieldValue = table.Rows[x]['CustomerID'];

   di.addregion(fieldValue);

   var qorders=di.querydb("select * from Orders where customerid='"+fieldValue+"'");

   di.push("orders");

}

'''More Examples'''

a. Accessing Column names

var table = di.querydb("select top 2 * from customers where hasregionflag='Y'");

for(var x=0;x<table.Columns.Count;x++)

{

   var _colName= table.Columns[x].ColumnName;

di.display("colname="+_colName);

}

b. Altering data before pushing - you can add a column and alter existing

var table = di.querydb("select * from customers");

table.Column.Add("SomeCustomfield");

///adds a column to the dataset

for(var x=0;x<table.Rows.Count;x++) {

var fieldValueID = table.Rows[x]['CustomerID'];

var fieldValueCode = table.Rows[x]['CustomerCode'];

table.Rows[x]['SomeCustomfield']=fieldValueID+fieldValueCode; //composite field

}

///pass in the altered dataset

di.push("customers", table);

};
