Query By Form

Top  Previous  Next

Query by form is used to select records with a file. Before the buttons below are enabled the user must select a data bound form. In this example we will use the customer form. Other typical forms would be the debtors master file, Creditors Master file, Job master file, Inventory file`         etc.

This process is very useful to change customer data for customers with common data as per example below.

<>        Not Equal to

<        Less Than

>        Greater Than

>=        Greater Than and Equal To

 

Comparison Value:

This is usually a literal value such as text or a number.

If the drop down is pressed a popup of existing dictionaries can be used as a comparison value. THIS IS NOT A COMMON SELECTION CRITERIA.
