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_nam\>"

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 don't need to escape field names that:

• have characters matching a-zA-Z0-9_
• don't begin with a number

Escaping field names with the syntax %\<field_nam\>" 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.
