Reference a Field with Special Characters
The Sumo Logic query language allows alphanumeric characters and underscores for field names, with the exception of starting a field name with a number. In cases where a field name contains special characters, you need to escape the field name by using the following syntax when calling the field in the query:
%"<field_name>"
For example:
| keyvalue regex " ([A-Z_-]+?)='([^']+?)'" keys "TYPE", "CHANNEL", "DOCUMENT-URI"
| count by %"document-uri"
tip
You can create a field with the as operator.
Limitations
You do not need to escape field names that:
- have characters matching
a-zA-Z0-9_. - do not begin with a number or
.(dot) - do not have more than one
.(dot) together
Escaping field names with the syntax %"<field_name>" is a safe practice when using special characters. You will need to escape any quote characters " with a backslash \ to use them in the field name when referencing a field with special characters.
