RowSet

所有超级接口:

```
public interface RowSet
extends ResultSet
```
The interface that adds support to the JDBC API for the JavaBeans™ 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.

      throws SQLException
```
    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.

    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). If the second argument is an InputStream then the stream must contain the number of bytes specified by scaleOrLength. If the second argument is a Reader then the reader must contain the number of characters specified * by scaleOrLength. If these conditions are not true the driver will generate a SQLException when the prepared statement is executed.
    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, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

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

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.

    Sets the designated parameter to a java.sql.NClob object. The object implements the java.sql.NClob interface. This NClob object maps to a SQL NCLOB.
    
    参数:
    
    parameterName - the name of the column to be set
    
    value - the parameter value

```
    Sets the designated parameter to a Reader object. The reader must contain the number of characters specified by length otherwise a SQLException will be generated when the CallableStatement is executed. This method differs from the setCharacterStream (int, Reader, int) method because it informs the driver that the parameter value should be sent to the server as a NCLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be send to the server as a LONGNVARCHAR or a NCLOB
    
    参数:
    
    parameterName - the name of the parameter to be set
    
    reader - An object that contains the data to set the parameter value to.
    
    length - the number of characters in the parameter data.
    
    抛出:
    
    SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if the length specified is less than zero; if the driver does not support national character sets; if the driver can detect that a data conversion error could occur; if a database access error occurs or this method is called on a closed CallableStatement

    Sets the designated parameter to a Reader object.
