Null Expression Values

The expression returns NULL if one of the values in the expression is null. However, you can configure an expression to return a non-null value.

If the expression refers to a lookup port, but the source data is new, the lookup port contains a default value. The default might be NULL. You can configure an IsNull expression to check for null values.

For example, the following expression checks if lookup_column is NULL:

iif (isnull(lookup_column), input_port, user_expression)

If the column is null, then return the input_port value. Otherwise return the value of the expression.
