A Row Set represents a set of rows produced by a
plan and read from the database. The parameterized type will be
RowRecord when reading each row as a map and can be a JSON read
handle when reading each row as a JSON document, or an XML read
handle when reading each row as a XML document. The parameterized
type can also be a JSON or XML IO representation with a registered
handle such as a Jackson JsonNode or an XML DOM Document.
Identifies the data types of the columns. The
array lists the data types only if the rows were requested with a
RowManager configured by calling the setDatatypeStyle() method with
RowSetPart.HEADER. Note that setting the data type style to HEADER
does not cast the values of the column. The actual data type of the
column values may be different from the header data type if the
column values are inconsistent.
