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‚Äč

You don't need to escape field names that:

  • have characters matching a-zA-Z0-9_.
  • don't begin with a number or . (dot)
  • don't have more than one . (dot) together

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.
