BY.EXP.DSND, BY-EXP-DSND
BY.EXP.DSND, BY-EXP-DSND |
|
|
The BY.EXP.DSND sort clause keyword applied to a multivalued field causes the query processor to explode the multivalued items to form separate single valued records and to sort these into descending order prior to display or when building a select list.
Format
BY.EXP.DSND {NO.CASE} field {explosion.limiter}
where
The BY.EXP.DSND keyword causes records to be sorted into descending order of the values stored in the specified field. The comparison is performed before conversion of the data to its display format. If the display format is left justified, a left justified sort is performed. Conversely, if the display format is right justified, a right justified sort is performed.
The optional NO.CASE keyword causes the sort to be performed in a case insensitive manner. Effectively, all comparisons are done using an uppercase version of the data being compared. Use of the QUERY.SORT.NO.CASE setting of the OPTION command implies the NO.CASE qualifier.
If more than one sort clause is present, sort criteria are applied in the order in which they are specified. If more than one exploded sort clause is present, they must all be on the same association.
Example
The command
LIST ORDERS PART.NO QTY LINE.TOTAL
might produce a display such as that below.
LIST ORDERS PART.NO QTY PRICE LINE.TOTAL ORDER PART QTY PRICE TOTAL. 24842 648 7 10.00 70.00 216 3 8.00 24.00 24851 107 2 12.50 25.00 24856 319 6 4.50 27.00 372 1 18.75 18.75 3 records listed.
The command
LIST ORDERS PART.NO QTY LINE.TOTAL BY.EXP.DSND PART.NO
applied to the same data would produce the display below.
LIST ORDERS PART.NO QTY PRICE LINE.TOTAL ORDER PART QTY PRICE TOTAL. 24842 648 7 10.00 70.00 24856 372 1 18.75 18.75 24856 319 6 4.50 27.00 24842 216 3 8.00 24.00 24851 107 2 12.50 25.00 3 records, 5 values listed.
Adding an explosion limiter to this query to show only part numbers greater than 300: LIST ORDERS PART.NO QTY LINE.TOTAL BY.EXP.DSND PART.NO > 300 would produce he report below.
LIST ORDERS PART.NO QTY PRICE LINE.TOTAL ORDER PART QTY PRICE TOTAL. 24842 648 7 10.00 70.00 24856 372 1 18.75 18.75 24856 319 6 4.50 27.00 2 records, 3 values listed.
