| service ResultSet |
- Description
- provides access to a table of data. A ResultSet
object is usually generated by executing a Statement.
A ResultSet maintains a cursor pointing to its current row of
data. Initially the cursor is positioned before the first row.
The 'next' method moves the cursor to the next row.
The getXXX methods retrieve column values for the current
row. You can retrieve values using either the index number of the
column. Columns are numbered from 1.
For maximum portability, ResultSet columns within each row should be
read in left-to-right order and each column should be read only once.
For the getXXX methods, the SDBC driver attempts to convert the
underlying data to the specified type and returns a suitable
value.
Column names used as input to the findColumn method are case
insensitive. When several columns have the same name, then the value
of the first matching column will be returned. The column name option is
designed to be used when column names are used in the SQL
query. For columns that are NOT explicitly named in the query, it
is best to use column numbers. If column names are used, there is
no way for the programmer to guarantee that they actually refer to
the intended columns.
A ResultSet is automatically closed (disposed) by the Statement that
generated it when that Statement is closed, re-executed, or used
to retrieve the next result from a sequence of multiple results.
The number, types, and properties of a ResultSet's columns are
provided by the ResultSetMetaData object returned by the getMetaData
method.

CursorName
[ readonly ] string CursorName;
- Usage Restrictions
- optional
- Description
- defines the SQL cursor name that will be used by subsequent Statement
execute
methods.
This name can then be used in SQL positioned update/delete statements to
identify the current row in the ResultSet generated by this statement. If
the database doesn't support positioned update/delete, this property is
a noop. To insure that a cursor has the proper isolation level to support
updates, the cursor's SELECT statement should be of the form
'select for update ...'. If the 'for update' phrase is omitted,
positioned updates may fail.
Note:
By definition, positioned update/delete
execution must be done by a different Statement than the one
which generated the ResultSet being used for positioning. Also,
cursor names must be unique within a connection.
