java.lang.Object | +--com.ibm.ims.rds.ClientResultSet
ClientResultSet represents a FORWARD_ONLY Result Set.
A ResultSet 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 or the name of the column. In general, using the column index will be more efficient. 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 JDBC driver attempts to convert the underlying data to the specified Java type and returns a suitable Java value. See the JDBC specification for allowable mappings from SQL types to Java types with the ResultSet.getXXX methods.
Column names used as input to getXXX methods are case insensitive. When performing a getXXX using a column name, if 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 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 ResulSetMetaData object returned by the getMetaData method.

- if a database access error occurspublic java.lang.String getCursorName() throws java.sql.SQLException
In SQL, a result table is retrieved through a cursor that is named. The current row of a result can be updated or deleted using a positioned update/delete statement that references the cursor name. To insure that the cursor has the proper isolation level to support update, the cursor's select statement should be of the form 'select for update'. If the 'for update' clause is omitted the positioned updates may fail.
JDBC supports this SQL feature by providing the name of the SQL cursor used by a ResultSet. The current row of a ResultSet is also the current row of this SQL cursor.
Note: If positioned update is not supported a RDSSQLException is thrown

Gets the value of a column in the current row as a Java object.
This method will return the value of the given column as a Java object. The type of the Java object will be the default Java object type corresponding to the column's SQL type, following the mapping for built-in types specified in the JDBC spec.
This method may also be used to read datatabase-specific

In the JDBC 2.0 API, the behavior of method

Moves the cursor to the given row number in the result set.
If the row number is positive, the cursor moves to the given row number with respect to the beginning of the result set. The first row is row 1, the second is row 2, and so on.
If the given row number is negative, the cursor moves to
an absolute row position with respect to
the end of the result set. For example, calling
absolute(-1)
positions the
cursor on the last row, absolute(-2)
indicates the next-to-last
row, and so on.
An attempt to position the cursor beyond the first/last row in the result set leaves the cursor before/after the first/last row, respectively.
Note: Calling absolute(1)
is the same
as calling first()
.
Calling absolute(-1)
is the same as calling last()

Attempting to move beyond the first/last row in the
result set positions the cursor before/after the
the first/last row. Calling relative(0)
is valid, but does
not change the cursor position.
Note: Calling relative(1)
is different from calling next()
because is makes sense to call next()
when there is no current row,
for example, when the cursor is positioned before the first row
or after the last row of the result set.

refreshRow
method provides a way for an application to
explicitly tell the JDBC driver to refetch a row(s) from the
database. An application may want to call refreshRow
when
caching or prefetching is being done by the JDBC driver to
fetch the latest value of a row from the database. The JDBC driver
may actually refresh multiple rows at once if the fetch size is
greater than one.
All values are refetched subject to the transaction isolation
level and cursor sensitivity. If refreshRow
is called after
calling updateXXX
, but before calling updateRow
, then the
updates made to the row are lost. Calling the method refreshRow
frequently
will likely slow performance.refreshRow
