Evaluates to true if haystack begins with needle.
haystack and needle can be any of the following:
- A String constant, such as "GDN".
- A Search Ads 360 variable that is a String, such as
Engine_status, and so on.
- An expression or formula column that returns a String.
Text comparisons are case insensitive. That is,
starts_with("gdn", "GDN") evaluates to true.
If you include an expression or formula column in this function, the expression or formula column could evaluate to an empty string.
Be aware that all Strings start with an empty (zero-length) String. That is,
starts_with("GDN", "") evaluates to true.
starts_with("", "GDN") evaluates to false. That is, an empty String does not start with non-empty Strings.
[starts_with("hook", "fishhook")]is false.
If a keyword contains "hoopers", and is contained in a campaign that starts with "US", display "US brand":
[if(and(contains(keyword, "hoopers"), starts_with(campaign, "US")), "US brand", "non-brand")]
