Parameters

sortName

A string that contains the name of the sort to use.

order An integer value that indicates the sort order for the sort; the value must be

DataSetIterator.Ascending or DataSetIterator.Descending.

Returns

Nothing.

Description

Method; switches the sort for the current iterator to the one specified by sortName, if it exists. If

the specified sort does not exist, a

DataSetError exception is thrown.

To create a sort, use

DataSet.applyUpdates().

Example

This code uses DataSet.hasSort() to determine if a sort named "customer" exists. If it does,

the code calls

DataSet.useSort() to make "customer" the current sort. Otherwise, the code

creates a sort by that name using

DataSet.addSort().

if(myDataSet.hasSort("customer")) {

myDataSet.useSort("customer");

} else {

myDataSet.addSort("customer", ["customer"], DataSetIterator.Descending);

}
