Single row

In some cases, the result-set must return a single row (or a single value). In these cases, most of the time it’s not possible (and needed) to define a key.

For these cases, NBi will let you define an option in the equal-to assertion through the attribute behavior and the value single-row. If you apply this setting, all the columns will be considered as values and the other options such as keys or values will not be considered.

<equal-to behavior="single-row">
  <query>select max(value), min(value) from myTable</query>
