Lesson 5: Querying the Database to Recall or Delete Data
Suppose you wish to periodically delete all samples in the database that are more than two weeks old
and were measured using the RSIN standardization mode. This lesson will step you through creating a
query that you can use over and over to find and delete these samples.
1. Choose Delete Measurement From Database from the File menu. The following screen will be
shown.
2. You cannot select the dates you want to delete or the standardization mode you wish from this
screen, so click More for more options. The screen will expand to show the following:
3. First, click the radio button next to “Sample,” so that you will find samples only, not standards or
series.
4. Click (check) the box next to “Include date in the search.”
5. Click the date drop-down in the “From” area to obtain a calendar on which you may select the
starting date for the search. The calendar starts out with today’s date marked. Since we wish to
delete all samples that are more than two weeks old, the starting date can be somewhat arbitrary.
Choose January 1, 2004, which is a date before EasyMatch QC was released.
