OPAL Case Sensitivity

Observe’s OPAL language is case sensitive by default. When you reference or search Observe objects and column names, case is required to match.

There are a few local options for case insensitivity.

Exceptions

Non-quoted search terms always match case-insensitively (though quoted search terms are case sensitive). See OPAL User Guide Examples.

The match_regex function can use regular expression engine flags to be case-insensitive. See match_regex.

The filter verb can use syntax cues to be case-insensitive. See filter.
