FIELD_VALUE
- The search value - a string, a date, a number.
- Examples:
- String: 'Paper 123'
- Date: '06/06/2007'
- Numeric Value: 9383
- Empty Field: '' or BLANK
- Follow these guidelines when specifying values:
- The value can be partial text or whole words
- Enclose strings and date/time values in 'single quotes'
- To specify date values, use the Date Format as specified in Company Information
- To search for a blank (empty) string, use two single quotes, with nothing between them ('').
- To search for a blank (empty) field of other kinds, use a field value of BLANK
- To search for multiple field values, separate each value using vertical pipe (|)
- For example: company_name='Acme|Ajax'
- (The criteria is satisfied when the company name is either Acme or Ajax)
- To search for a field value that happens to contain a vertical pipe (|), you need to "escape" the pipe so it is recognized as a literal character in the field. To do that, you put a backslash in front of it: \|. For example, company_name contains '\|'
- That works in REST APIs and in the GUI.
- In Java strings, the backslash is already an escape character. (It combines with the one that follows it to create a single character.)
- So in Java code, you need two backslashes: \\|
- (The first two (\\) combine to become a single backslash (\), so the filter expression handler sees "\|", as desired.)
- Finally, note that "equals" does not work for this particular search. The required operator is "contains".
- To include a single quote in the value that you are searching for, specify an additional quote for every single quote ('').
- For example in business rules, in the execution criteria use the single quote as listed in the following images:
- When specified conditions are true:
- When specified expression is true:
