Conditions

A condition is a data operation that a rule statement specifies for one or more input data values. Every rule statement contains at least one condition.

When a condition validates an input data value, the rule specification performs the action in the rule statement. The action represents a potential output from the rule set. If a condition cannot validate an input data value, the rule specification does not perform the action.

Configure a condition to perform one of the following types of analysis:

Compare the input data values to a single value: The rule statement compares the values in the input column to the value that you enter.
Compare the input data values to the values on another input: The rule statement compares the values in the input column to the values on the same row in another input column that you specify.
Compare the input data values to the current date and time: The rule statement compares the values in the input column to the current date and time.
Search for null values: The rule statement searches the input column for null or empty strings.
Compare the input data values to a range of values: The rule statement compares the values in the input column to a range of values that you enter.
Compare the input data values to the values in a dictionary: The rule statement compares the values in the input column to the values in a dictionary. The rule statement returns a value from the dictionary or a value that you enter.
Compare the input data values to the output from another rule specification: The rule statement compares the values in the input column to the output from a rule specification that you select. The rule specification runs within the rule statement logic.; Specify at least one input for the rule specification. You can select any input available to the current rule specification, including the current condition input, or you can enter a value as a rule specification input. You also select the field that the condition reads as the rule specification output.
Compare the input data values to the output from a mapplet: The rule statement compares the values in the input column to the output from a mapplet that you select. The mapplet runs within the rule statement logic.; Specify at least one input for the mapplet. You can select any input available to the current rule specification, including the current condition input, or you can enter a value as a mapplet input. You also select the field that the condition reads as the mapplet output.; A rule specification can read mapplets that contain passive transformations.
Apply a function expression to the input data values: The rule statement applies a function expression that you select to the values in one or more input columns.
Apply a custom expression to the input data values: The rule statement applies a custom expression that you define to the values in one or more input columns.
