Sort Columns

One can sort a table using up to three columns as sorting keys. All the available columns are listed in the left list box.

Selecting keys

Click on the desired column name in the list box then click on any of the "Primary Column", "Second Column", or "Third column" buttons on the right. The column name will be placed in the entry box for that sort key. Only the primary column is required.

Ascending options

Any of the columns selected as a sorting key can be sorted in the ascending or decending order by (de)selecting the associated checkbox.

Logical type columns are treated as int arrays of 0/1, and the BIT type (X) columns are sorted by the first bit.

Delete option

If selected as "Yes", rows with identical sort key values will be deleted (i.e. only one row will be kept, the rest are removed from the file).
