This example shows an instance of the WhereClause class (or one of its specializations) that defines a simple condition based on a missing value. The example shown specifies that the value of the BASE variable in the ADVS dataset is not missing, which could be expressed as any of the following:

  • ADVS.BASE NE ''
  • ADVS.BASE IS NOT MISSING
  • ADVS.BASE IS NOT NULL

Note that some attributes (such as the expected level and order attributes) have been excluded from this example. 

YAML Example
...
condition:
  dataset: ADVS
  variable: BASE
  comparator: NE
  value:

This condition could be represented in tabular form as:

$titleHtml
datasetvariablecomparatorvalue
ADVSBASENE
$warningHtml
Other conditions based on a missing value (i.e., with a comparator value of "EQ" or "NE") would be represented similarly.
