Sorting tables

We will now introduce the Order By statement, which is added to a Load statement and is used to sort an input table based on certain fields. There is one major condition for the Order By statement to work: it must be applied to a Load statement getting data from a Resident table, not from a table file or any other source.

Some databases can receive Order By instructions in the Select query, but in this section we will only deal with Order By statements on the QlikView side.

The Order By statement must receive at least one field name over which the ordering will be performed and, optionally, the sort order (either ascending or descending). If the sort order is not specified along with the field name, the default sort order will be applied, which is ascending.

An example script of an Order By statement at play is:

Load
 Region,
 Date,
 Amount
Resident SalesTable
Order By Date asc;

In this script, we are loading three fields (Region, Date, and Amount) from a previously loaded table...
