Filter Expression Format

Single-field expression:

<FieldName> <Comparison Operator> <Value>

Example of multiple-field expressions joined by logical operators:

<FieldName> <Comparison Operator> <Value> AND (<FieldName> <Comparison Operator> <Value>
  OR <FieldName> <Comparison Operator> <Value>) ...

Text field values are included within single quotes. Examples of a single-field expression filtering on a Text field:

Industry = 'Agriculture'
Industry LIKE 'A%'

Example of a single-field expression filtering on a Date field:

LastViewedDate > 2021-11-03T09:30:11-08:00

Example of a single-field expression filtering on a Time field (the UTC time zone designator Z is required):

OpenTime__c >= 14:30:00Z

Example of a single-field expression filtering on a ChangeEventHeader field:

ChangeEventHeader.changeType = 'UPDATE'

Examples of a multiple-field expression:

Industry = 'Agriculture' AND NumberOfEmployees > 1000

Example of a multiple-field expression using parentheses and the AND and OR logical operators:

NumberOfEmployees > 1000 AND (Industry = 'Agriculture' OR Industry = 'Banking')

Standard and custom compound fields are supported in filter expressions when you specify their component fields in the filter expression but not the compound field itself. This table contains compound fields and examples of component fields that you can use in a filter expression.

Name.FirstName = 'John' 
Name.LastName = 'Smith'

Name = 'John Smith'

BillingAddress.City = 'San Francisco'

My_Location__c.Latitude > 40

Supported Comparison Operators

These comparison operators are supported in filter expressions.

• =
• !=
• >
• <
• >=
• <=
• LIKE

Considerations for the LIKE Operator

The LIKE operator is supported for Text fields. The text string value must be enclosed in single quotes. The LIKE operator can match partial text string values when used with the % and _ wildcards. The % wildcard matches zero or more characters. The _ wildcard matches exactly one character.

For example, this expression matches messages with Industry values that start with 'A', such as 'Agriculture' and 'Apparel'. But it doesn’t match Industry values that don’t start with 'A', such as 'Education'.

Industry LIKE 'A%'

This expression matches messages with Industry values that start with 'Agricultur' and end with any single character. For example, 'Agriculture' is a match.

Industry LIKE 'Agricultur_'

Supported Logical Operators

These logical operators are supported in filter expressions.

• AND
• OR
• NOT

Considerations for the NOT Operator

Use the NOT operator to negate an expression. For example, this expression states that the industry isn’t Banking.

NOT Industry = 'Banking'

In this next expression, the NOT operator negates two conditions evaluated with the AND operator. The filter matches events that have the industry set to a value other than Banking or NumberOfEmployees is less than or equal to 1,000. If an event has both the industry set to Banking and the NumberOfEmployees is greater than 1,000, it doesn’t match the filter criteria and isn’t delivered.

NOT(Industry = 'Banking' AND NumberOfEmployees>1000)

If there’s more than one expression, including the expression with the NOT operator, parentheses around NOT and its expression are required. In this example, two field expressions are joined by the AND operator. NOT is used only for the first expression. It must be enclosed within parentheses because there are two expressions. The entire filter expression states that the industry is not Banking and NumberOfEmployees is greater than 1,000.

(NOT(Industry = 'Banking')) AND (NumberOfEmployees>1000)

This example also requires enclosing the NOT operator in parentheses. This filter expression matches events that have a last viewed date greater than 2021-10-21T09:30:11 in the Pacific time zone and the industry is not Banking or NumberOfEmployees is less than or equal to 1,000.

LastViewedDate>2021-10-21T09:30:11-08:00 AND (NOT(Industry = 'Banking' AND NumberOfEmployees>1000))
