New Sample: Query_FillMissingValues

by AD Tejpal

This sample db demonstrates filling up of missing values in a sequential series. Three types of source data are covered:
(a) Number series.
(b) Alpha-numeric series.
(c) Date series.

Subform on left shows the start and end values for each missing range of sequential values per PersonID. Subform at right depicts all the missing sequential values duly filled in. Each record representing start of a new sequence is highlighted in color.

A single field table (T_Ref) populated with sequential numbers from 0 onwards is used as the driver for eliciting the missing values. The number of records in this table should be such as to cover the maximum likely range of missing values.

Version: Access 2000 file format.
