Class ResultSetWrapper
- All Implemented Interfaces:
AutoCloseable
,ResultSet
,Wrapper
A ResultSet
object 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, and because it
returns false
when there are no more rows in the ResultSet
object, it can be used in a while
loop to iterate through the
result set.
A default ResultSet
object is not updatable and has a cursor
that moves forward only. Thus, it is possible to iterate through it only
once and only from the first row to the last row. New methods in the JDBC
2.0 API make it possible to produce ResultSet
objects that are
scrollable and/or updatable. The following code fragment, in which con
is a valid Connection
object, illustrates how to make a result
set that is scrollable and insensitive to updates by others, and that is
updatable. See ResultSet
fields for other options.
Statement stmt = con.createStatement( ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE); ResultSet rs = stmt.executeQuery("SELECT a, b FROM TABLE2"); // rs will be scrollable, will not show changes made by others, // and will be updatableThe
ResultSet
interface provides getXXX
methods for retrieving column values from the current row. Values can be
retrieved 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, result set columns within each
row should be read in left-to-right order, and each column should be read
only once.
For the getXXX
methods, a JDBC driver attempts to convert the
underlying data to the Java type specified in the XXX
part of
the getXXX
method and returns a suitable Java value. The JDBC
specification has a table showing the 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 a getXXX
method is called with a column name
and several columns have the same name, 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 that generated the result set. 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 set of updateXXX
methods were added to this interface in the
JDBC 2.0 API (JavaTM 2 SDK, Standard
Edition, version 1.2). The comments regarding parameters to the getXXX
methods also apply to parameters to the updateXXX
methods.
The updateXXX
methods may be used in two ways:
- to update a column value in the current row. In a scrollable
ResultSet
object, the cursor can be moved backwards and forwards, to an absolute position, or to a position relative to the current row. The following code fragment updates theNAME
column in the fifth row of theResultSet
objectrs
and then uses the methodupdateRow
to update the data source table from whichrs
was derived.rs.absolute(5); // moves the cursor to the fifth row of rs rs.updateString("NAME", "AINSWORTH"); // updates the //
NAME
column of row 5 to beAINSWORTH
rs.updateRow(); // updates the row in the data source - to insert column values into the insert row. An updatable
ResultSet
object has a special row associated with it that serves as a staging area for building a row to be inserted. The following code fragment moves the cursor to the insert row, builds a three-column row, and inserts it intors
and into the data source table using the methodinsertRow
.rs.moveToInsertRow(); // moves cursor to the insert row rs.updateString(1, "AINSWORTH"); // updates the // first column of the insert row to be
AINSWORTH
rs.updateInt(2,35); // updates the second column to be35
rs.updateBoolean(3, true); // updates the third row totrue
rs.insertRow(); rs.moveToCurrentRow();
A ResultSet
object is automatically closed when the Statement
object that generated it 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
object's
columns are provided by the ResulSetMetaData
object returned by
the ResultSet.getMetaData
method.

in interfaceResultSet
- Throws:
SQLException
- if a database access error occurs or the result set type isTYPE_FORWARD_ONLY
- Since:
- 1.2
-
afterLast
Moves the cursor to the end of thisResultSet
object, just after the last row. This method has no effect if the result set contains no rows.- Specified by:
afterLast
in interfaceResultSet
- Throws:
SQLException
- if a database access error occurs or the result set type isTYPE_FORWARD_ONLY

-
absolute
Moves the cursor to the given row number in thisResultSet
object.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 the method
absolute(-1)
positions the cursor on the last row; calling the methodabsolute(-2)
moves the cursor to 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 the first row or after the last row.
Note: Calling
absolute(1)
is the same as callingfirst()
. Callingabsolute(-1)
is the same as callinglast()
.- Specified by:
absolute
in interfaceResultSet
- Parameters:
row
- the row to move to- Returns:
true
if the cursor is on the result set;false

-
relative
Moves the cursor a relative number of rows, either positive or negative. Attempting to move beyond the first/last row in the result set positions the cursor before/after the the first/last row. Callingrelative(0)
is valid, but does not change the cursor position.Note: Calling the method
relative(1)
is different from calling the methodnext()
because is makes sense to callnext()
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.- Specified by:
relative
in interfaceResultSet
- Parameters:
rows
- the number of rows to move- Returns:
true
if the cursor is on a row;false
otherwise- Throws:

previous()
is not the same as calling the methodrelative(-1)
because it makes sense to callprevious() when there is no current row.- Specified by:
previous
in interfaceResultSet
- Returns:
true
if the cursor is on a valid row;false
if it is off the result set- Throws:
SQLException
- if a database access error occurs or the result set type isTYPE_FORWARD_ONLY
- Since:
- 1.2
-
rowUpdated

refreshRow
Refreshes the current row with its most recent value in the database. This method cannot be called when the cursor is on the insert row.The
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 callrefreshRow
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 anupdateXXX
method, but before calling the methodupdateRow
, then the updates made to the row are lost. Calling the methodrefreshRow
frequently will likely slow performance.- Specified by:
refreshRow
in interfaceResultSet
- Throws:
SQLException
- if a database access error occurs or if this method is called when the cursor is on the insert row- Since:
- 1.2
-
cancelRowUpdates

in interfaceResultSet
- Throws:
SQLException
- if a database access error occurs or if this method is called when the cursor is on the insert row- Since:
- 1.2
-
moveToInsertRow
Moves the cursor to the insert row. The current cursor position is remembered while the cursor is positioned on the insert row. The insert row is a special row associated with an updatable result set. It is essentially a buffer where a new row may be constructed by calling theupdateXXX
methods prior to inserting the row into the result set. Only theupdateXXX
,getXXX
, andinsertRow
methods may be called when the cursor is on the insert row. All of the columns in a result set must be given a value each time this method is called before callinginsertRow
. AnupdateXXX
method must be called before agetXXX
method can be called on a column value.- Specified by:
