Move backward through the table from the end, looking for a row that exactly matches a value or full set of values in the current index.
Boolean findLast( )
true if successful, false otherwise.
To specify the value for which to search, set the column value for each column in the index. The cursor is left on the first row found that exactly matches the index value. On failure the cursor position is before the first row (isBOF).
Each search must be preceded by a call to the findBegin method.
