Using expressions
The information in this section is for advanced users who want
to:
- Modify predefined expressions.
- Select resources.
- Filter audit log records by compiling and running a complex mathematical expression against a set of values.
An expression is similar to a C language statement or the WHERE
clause of an SQL query. It is composed of variables, operators, and
constants. The C and SQL syntax styles may be intermixed within a
single expression. The following table relates the RMC terminology
to SQL terminology:
RMC | SQL |
---|---|
attribute name | column name |
select string | WHERE clause |
operators | predicates, logical connectives |
resource class | table |
