RANDOM_RECORDS Function

Syntax

Arguments

Filter_Expression

An expression that selects records from a table.

count

An integer number greater than 0. The count of records to return.

filter

Optional. Default = ".T." (All records). A character filter expression that evaluates to a logical value and selects records from the table.

Description

Return 'count' random records.

Discussion

RANDOM_RECORDS() is a special function used only in queries to return a random number of records from the current table. If the optional Filter is supplied, the random records are selected from the records selected by the filter.

See Top, Bottom, Nth Record and Random Record Queries for more information. The following query returns 10 randomly selected orders placed after May 1, 2000.

dim tbl as P
dim inx as P
tbl = table.current()
query.filter = "random_records(10, \"orderdate > {5/1/2000}\")"
query.order = "order_total"
inx = tbl.query_create()
topparent.resynch()
