ResultSet
Java SE 6
| public interface java.sql ResultSet
|
Java SE 6 |
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, you can
iterate through it only once and only from the first row to the
last row. It is 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 updatable
The ResultSet interface provides
getter methods (getBoolean, getLong, and so on)
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 getter methods, a JDBC driver attempts
to convert the underlying data to the Java type specified in the
getter method and returns a suitable Java value. The JDBC specification
has a table showing the allowable mappings from SQL types to Java types
that can be used by the ResultSet getter methods.
Column names used as input to getter methods are case insensitive. When a getter 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, the programmer should take care to guarantee that they uniquely refer to the intended columns, which can be assured with the SQL AS clause.
A set of updater 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 getter methods also apply to parameters to the updater methods.
The updater methods may be used in two ways:
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 the NAME column
in the fifth row of the ResultSet object
rs and then uses the method updateRow
to update the data source table from which rs 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 be AINSWORTH
rs.updateRow(); // updates the row in the data source
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 into rs and into
the data source table using the method insertRow.
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 be 35
rs.updateBoolean(3, true); // updates the third column to true
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.

| Methods | |||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| public boolean | absolute(int row) throws SQLException Details
Moves the cursor to the given row number in
this ResultSet 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
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
| ||||||||||||
| public void | afterLast() throws SQLException Details
Moves the cursor to the end of
this ResultSet object, just after the
last row. This method has no effect if the result set contains no rows.
| ||||||||||||
| public void | beforeFirst() throws SQLException Details
Moves the cursor to the front of
this ResultSet object, just before the
first row. This method has no effect if the result set contains no rows.
| ||||||||||||
| public void | cancelRowUpdates() throws SQLException Details
Cancels the updates made to the current row in this
ResultSet object.
This method may be called after calling an
updater method(s) and before calling
the method updateRow to roll back
the updates made to a row. If no updates have been made or
updateRow has already been called, this method has no
effect.
| ||||||||||||
| public void | clearWarnings() throws SQLException Details
Clears all warnings reported on this ResultSet object.
After this method is called, the method getWarnings
returns null until a new warning is
reported for this ResultSet object.

Maps the given ResultSet column label to its
ResultSet column index.
| ||||||||||||
| public boolean | first() throws SQLException Details
Moves the cursor to the first row in
this ResultSet object.
| ||||||||||||
| public void | insertRow() throws SQLException Details
Inserts the contents of the insert row into this
ResultSet object and into the database.
The cursor must be on the insert row when this method is called.
| ||||||||||||
| public boolean | last() throws SQLException Details
Moves the cursor to the last row in
this ResultSet object.
| ||||||||||||
| public void | moveToCurrentRow() throws SQLException Details
Moves the cursor to the remembered cursor position, usually the
current row. This method has no effect if the cursor is not on
the insert row.
| ||||||||||||
| public void | moveToInsertRow() throws SQLException Details
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 the updater methods prior to
inserting the row into the result set.
Only the updater, getter,
and insertRow 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 calling insertRow.
An updater method must be called before a
getter method can be called on a column value.
| ||||||||||||
| public boolean | next() throws SQLException Details
Moves the cursor froward one row from its current position.
A ResultSet cursor is initially positioned
before the first row; the first call to the method
next makes the first row the current row; the
second call makes the second row the current row, and so on.
