Syntax

Parameters

ParameterTypeDescription
keyColumnValuesObject...

Ordered, boxed values for the key columns, in the same order as keyColumnNames().

The keyColumnValues can be thought of as a tuple constraining the values for the corresponding key columns for the result row. If there are no matching rows, the result is null. If there are multiple matching rows, an UnsupportedOperationException is thrown.

Returns

A single constituent for the supplied keyColumnValues.
