The interface that adds support to the JDBC API for the JavaBeansTM component model. A rowset, which can be used as a JavaBeans component in a visual Bean development environment, can be created and configured at design time and executed at run time.

The RowSet interface provides a set of JavaBeans properties that allow a RowSet instance to be configured to connect to a JDBC data source and read some data from the data source. A group of setter methods (setInt, setBytes, setString, and so on) provide a way to pass input parameters to a rowset's command property. This command is the SQL query the rowset uses when it gets its data from a relational database, which is generally the case.

The RowSet interface supports JavaBeans events, allowing other components in an application to be notified when an event occurs on a rowset, such as a change in its value.

The RowSet interface is unique in that it is intended to be implemented using the rest of the JDBC API. In other words, a RowSet implementation is a layer of software that executes "on top" of a JDBC driver. Implementations of the RowSet interface can be provided by anyone, including JDBC driver vendors who want to provide a RowSet implementation as part of their JDBC products.

A RowSet object may make a connection with a data source and maintain that connection throughout its life cycle, in which case it is called a connected rowset. A rowset may also make a connection with a data source, get data from it, and then close the connection. Such a rowset is called a disconnected rowset. A disconnected rowset may make changes to its data while it is disconnected and then send the changes back to the original source of the data, but it must reestablish a connection to do so.

A disconnected rowset may have a reader (a RowSetReader object) and a writer (a RowSetWriter object) associated with it. The reader may be implemented in many different ways to populate a rowset with data, including getting data from a non-relational data source. The writer can also be implemented in many different ways to propagate changes made to the rowset's data back to the underlying data source.

Rowsets are easy to use. The RowSet interface extends the standard java.sql.ResultSet interface. The RowSetMetaData interface extends the java.sql.ResultSetMetaData interface. Thus, developers familiar with the JDBC API will have to learn a minimal number of new APIs to use rowsets. In addition, third-party software tools that work with JDBC ResultSet objects will also easily be made to work with rowsets.

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 absolute(-1) positions the cursor on the last row; calling the method absolute(-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 calling first(). Calling absolute(-1) is the same as calling last().

Parameters
rowthe number of the row to which the cursor should move. A positive number indicates the row number counting from the beginning of the result set; a negative number indicates the row number counting from the end of the result set
Return
true if the cursor is on the result set; false otherwise

Clears the parameters set for this RowSet object's command.

In general, parameter values remain in force for repeated use of a RowSet object. Setting a parameter value automatically clears its previous value. However, in some cases it is useful to immediately release the resources used by the current parameter values, which can be done by calling the method clearParameters.

Throws
SQLExceptionif a database access error occurs
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.
Throws

Releases this ResultSet object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed.

Note: A ResultSet object is automatically closed by the Statement object that generated it when that Statement object is closed, re-executed, or is used to retrieve the next result from a sequence of multiple results. A ResultSet object is also automatically closed when it is garbage collected.

Throws

Fills this RowSet object with data.

The execute method may use the following properties to create a connection for reading data: url, data source name, user name, password, transaction isolation, and type map. The execute method may use the following properties to create a statement to execute a command: command, read only, maximum field size, maximum rows, escape processing, and query timeout.

If the required properties have not been set, an exception is thrown. If this method is successful, the current contents of the rowset are discarded and the rowset's metadata is also (re)set. If there are outstanding updates, they are ignored.

If this RowSet object does not maintain a continuous connection with its source of data, it may use a reader (a RowSetReader object) to fill itself with data. In this case, a reader will have been registered with this RowSet object, and the method execute will call on the reader's readData method as part of its implementation.

Retrieves the name of the SQL cursor used by this ResultSet object.

In SQL, a result table is retrieved through a cursor that is named. The current row of a result set 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 FOR UPDATE is omitted, the positioned updates may fail.

The JDBC API supports this SQL feature by providing the name of the SQL cursor used by a ResultSet object. The current row of a ResultSet object is also the current row of this SQL cursor.

Note: If positioned update is not supported, a SQLException is thrown.

Return
the SQL name for this ResultSet object's cursor
Throws

Retrieves the value of the designated column in the current row of this ResultSet object as as a stream of two-byte Unicode characters. The first byte is the high byte; the second byte is the low byte. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHARvalues. The JDBC driver will do any necessary conversion from the database format into Unicode.

Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return 0 when the method InputStream.available is called, whether there is data available or not.

Parameters
columnIndexthe first column is 1, the second is 2, ...
Return
a Java input stream that delivers the database column value as a stream of two-byte Unicode characters; if the value is SQL NULL, the value returned is null
Throws
SQLExceptionif a database access error occurs
@deprecated

Retrieves the value of the designated column in the current row of this ResultSet object as a stream of two-byte Unicode characters. The first byte is the high byte; the second byte is the low byte. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHAR values. The JDBC technology-enabled driver will do any necessary conversion from the database format into Unicode.

Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return 0 when the method InputStream.available is called, whether there is data available or not.

Parameters
columnNamethe SQL name of the column
Return
a Java input stream that delivers the database column value as a stream of two-byte Unicode characters. If the value is SQL NULL, the value returned is null.

Retrieves the first warning reported by calls on this ResultSet object. Subsequent warnings on this ResultSet object will be chained to the SQLWarning object that this method returns.

The warning chain is automatically cleared each time a new row is read. This method may not be called on a ResultSet object that has been closed; doing so will cause an SQLException to be thrown.

Note: This warning chain only covers warnings caused by ResultSet methods. Any warning caused by Statement methods (such as reading OUT parameters) will be chained on the Statement object.

Return
the first SQLWarning object reported or null if there are none
Throws
SQLExceptionif a database access error occurs or this method is called on a closed result set
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.
Throws

1.2
Retrieves whether the cursor is before the first row in this ResultSet object.
Return
true if the cursor is before the first row; false if the cursor is at any other position or the result set contains no rows
Throws
SQLExceptionif a database access error occurs
@since
1.2
Retrieves whether the cursor is on the first row of this ResultSet object.
Return
true if the cursor is on the first row; false otherwise
Throws
SQLExceptionif a database access error occurs
@since
1.2
Retrieves whether the cursor is on the last row of this ResultSet object. Note: Calling the method isLast may be expensive because the JDBC driver might need to fetch ahead one row in order to determine whether the current row is the last row in the result set.
Return
true if the cursor is on the last row; false otherwise
Throws
SQLExceptionif a database access error occurs
@since
1.2
Retrieves whether this RowSet object is read-only. If updates are possible, the default is for a rowset to be updatable.

Attempts to update a read-only rowset will result in an SQLException being thrown.

Return
true if this RowSet object is read-only; false if it is updatable
See Also
Moves the cursor to the last row in this ResultSet object.
Return
true if the cursor is on a valid row; false if there are no rows in the result set
Throws
SQLExceptionif a database access error occurs or the result set type is TYPE_FORWARD_ONLY
@since
1.2
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.
Throws
SQLExceptionif a database access error occurs or the result set is not updatable
@since
1.2
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.
Throws
SQLExceptionif a database access error occurs or the result set is not updatable
@since
1.2
Moves the cursor down 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.

If an input stream is open for the current row, a call to the method next will implicitly close it. A ResultSet object's warning chain is cleared when a new row is read.

Return
true if the new current row is valid; false if there are no more rows
Throws
SQLExceptionif a database access error occurs
Moves the cursor to the previous row in this ResultSet object.
Return
true if the cursor is on a valid row; false if it is off the result set
Throws
SQLExceptionif a database access error occurs or the result set type is TYPE_FORWARD_ONLY
@since
1.2
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 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 an updater method, but before calling the method updateRow, then the updates made to the row are lost. Calling the method refreshRow frequently will likely slow performance.

Throws
SQLExceptionif a database access error occurs or if this method is called when the cursor is on the insert row
@since
1.2
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. Calling relative(0) is valid, but does not change the cursor position.

Note: Calling the method relative(1) is identical to calling the method next() and calling the method relative(-1) is identical to calling the method previous().

Parameters
rowsan int specifying the number of rows to move from the current row; a positive number moves the cursor forward; a negative number moves the cursor backward
Return
true if the cursor is on a row; false otherwise
Throws
SQLExceptionif a database access error occurs, there is no current row, or the result set type is TYPE_FORWARD_ONLY
@since
1.2

sqlTypea SQL type code defined by java.sql.Types
Throws
SQLExceptionif a database access error occurs
Sets the designated parameter in this RowSet object's SQL command to SQL NULL. This version of the method setNull should be used for SQL user-defined types (UDTs) and REF type parameters. Examples of UDTs include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.

Note: To be portable, applications must give the SQL type code and the fully qualified SQL type name when specifying a NULL UDT or REF parameter. In the case of a UDT, the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for UDT and REF parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the typeName parameter is ignored.

Parameters
paramIndexthe first parameter is 1, the second is 2, ...
sqlTypea value from java.sql.Types
typeNamethe fully qualified name of an SQL UDT or the type name of the SQL structured type being referenced by a REF type; ignored if the parameter is not a UDT or REF type
Throws
SQLExceptionif a database access error occurs
Sets the designated parameter in this RowSet object's command with a Java Object. For integral values, the java.lang equivalent objects should be used.

The JDBC specification provides a standard mapping from Java Object types to SQL types. The driver will convert the given Java object to its standard SQL mapping before sending it to the database.

Note that this method may be used to pass datatabase-specific abstract data types by using a driver-specific Java type. If the object is of a class implementing SQLData, the rowset should call the method SQLData.writeSQL to write the object to an SQLOutput data stream. If the object is an instance of a class implementing the Ref, Struct, Array, Blob, or Clob interfaces, the driver uses the default mapping to the corresponding SQL type.

An exception is thrown if there is an ambiguity, for example, if the object is of a class implementing more than one of these interfaces.

Parameters
parameterIndexThe first parameter is 1, the second is 2, ...
xThe object containing the input parameter value
Throws
SQLExceptionif a database access error occurs
Sets the designated parameter in this RowSet object's command with a Java Object. For integral values, the java.lang equivalent objects should be used. This method is like setObject above, but the scale used is the scale of the second parameter. Scalar values have a scale of zero. Literal values have the scale present in the literal.

Even though it is supported, it is not recommended that this method be called with floating point input values.

Parameters
parameterIndexthe first parameter is 1, the second is 2, ...
xthe object containing the input parameter value
targetSqlTypethe SQL type (as defined in java.sql.Types) to be sent to the database
Throws
SQLExceptionif a database access error occurs
Sets the designated parameter in this RowSet object's command with the given Java Object. For integral values, the java.lang equivalent objects should be used (for example, an instance of the class Integer for an int).

The given Java object will be converted to the targetSqlType before being sent to the database.

If the object is of a class implementing SQLData, the rowset should call the method SQLData.writeSQL to write the object to an SQLOutput data stream. If the object is an instance of a class implementing the Ref, Struct, Array, Blob, or Clob interfaces, the driver uses the default mapping to the corresponding SQL type.

Note that this method may be used to pass datatabase-specific abstract data types.

Parameters
parameterIndexthe first parameter is 1, the second is 2, ...
xthe object containing the input parameter value
targetSqlTypethe SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type.
