Figure 8.7: Data Filter Example 3
Example 3: Combining Logical AND Conditions and Logical
OR Conditions
This example combines a logical AND condition and a logical OR
Condition. Assume the Data Filter Format is defined as shown in
Figure 8.7.
Where:
A Is the field that lists the time the call was received or placed.
B Is the field that lists the extension number.
Given the Data Filter Format shown in Figure 8.7, define a Data Filter that
will store records for calls received or placed between 7:00 am (07:00) and
6:30 PM (18:30). In addition, the Data Filter must also store records for
calls received or placed by extension 013. The Data Filter Alarm Action
would be set at "Store", and Match Parameters would be defined as follows:
(A>07:00&A<18:30)+B=013
Where:
A>07:00 Stores records for calls received or placed after 07:00.
& Logical AND
A<18:30 Stores records for calls received or placed before 18:30.
+ Logical OR
B=013 Stores records for calls received or placed at extension 013.
Note: Parentheses are used to group the parts of the logical
AND condition.
