public abstract class BaseRowSet extends Object implements Serializable, Cloneable
RowSet
object with its basic functionality. The basic functions include having properties and sending event notifications, which all JavaBeans components must implement. BaseRowSet
class provides the core functionality for all RowSet
implementations, and all standard implementations may use this class in combination with one or more RowSet
interfaces in order to provide a standard vendor-specific implementation. To clarify, all implementations must implement at least one of the RowSet
interfaces (JdbcRowSet
, CachedRowSet
, JoinRowSet
, FilteredRowSet
, or WebRowSet
). This means that any implementation that extends the BaseRowSet
class must also implement one of the RowSet
interfaces. The BaseRowSet
class provides the following:
RowSet
object's command RowSet
implementation does and how it gets its data. For example, rowsets that get their data from a ResultSet
object need to set the properties that are required for making a database connection. If a RowSet
object uses the DriverManager
facility to make a connection, it needs to set a property for the JDBC URL that identifies the appropriate driver, and it needs to set the properties that give the user name and password. If, on the other hand, the rowset uses a DataSource
object to make the connection, which is the preferred method, it does not need to set the property for the JDBC URL. Instead, it needs to set the property for the logical name of the data source along with the properties for the user name and password. NOTE: In order to use a DataSource
object for making a connection, the DataSource
object must have been registered with a naming service that uses the Java Naming and Directory Interface (JNDI) API. This registration is usually done by a person acting in the capacity of a system administrator.
ResultSet
object. This query is the command that is set for the RowSet
object's command property. The rowset populates itself with data by reading the data from the ResultSet
object into itself. If the query contains placeholders for values to be set, the BaseRowSet
setter methods are used to set these values. All setter methods allow these values to be set to null
if required. The following code fragment illustrates how the CachedRowSet
object crs
might have its command property set. Note that if a tool is used to set properties, this is the code that the tool would use.
crs.setCommand("SELECT FIRST_NAME, LAST_NAME, ADDRESS FROM CUSTOMERS" +
"WHERE CREDIT_LIMIT > ? AND REGION = ?");
In this example, the values for CREDIT_LIMIT
and REGION
are placeholder parameters, which are indicated with a question mark (?). The first question mark is placeholder parameter number 1
, the second question mark is placeholder parameter number 2
, and so on. Any placeholder parameters must be set with values before the query can be executed. To set these placeholder parameters, the BaseRowSet
class provides a set of setter methods, similar to those provided by the PreparedStatement
interface, for setting values of each data type. A RowSet
object stores the parameter values internally, and its execute
method uses them internally to set values for the placeholder parameters before it sends the command to the DBMS to be executed.
The following code fragment demonstrates setting the two parameters in the query from the previous example.
crs.setInt(1, 5000);
crs.setString(2, "West");
If the execute
method is called at this point, the query sent to the DBMS will be:
"SELECT FIRST_NAME, LAST_NAME, ADDRESS FROM CUSTOMERS" +
"WHERE CREDIT_LIMIT > 5000 AND REGION = 'West'"
NOTE: Setting Array
, Clob
, Blob
and Ref
objects as a command parameter, stores these values as SerialArray
, SerialClob
, SerialBlob
and SerialRef
objects respectively. BaseRowSet
class provides two kinds of setter methods, those that set properties and those that set placeholder parameters. The setter methods discussed in this section are those that set placeholder parameters. The placeholder parameters set with the BaseRowSet
setter methods are stored as objects in an internal Hashtable
object. Primitives are stored as their Object
type. For example, byte
is stored as Byte
object, and int
is stored as an Integer
object. When the method execute
is called, the values in the Hashtable
object are substituted for the appropriate placeholder parameters in the command.
A call to the method getParams
returns the values stored in the Hashtable
object as an array of Object
instances. An element in this array may be a simple Object
instance or an array (which is a type of Object
). The particular setter method used determines whether an element in this array is an Object
or an array.
The majority of methods for setting placeholder parameters take two parameters, with the first parameter indicating which placeholder parameter is to be set, and the second parameter giving the value to be set. Methods such as setInt
, setString
, setBoolean
, and setLong
fall into this category. After these methods have been called, a call to the method getParams
will return an array with the values that have been set. Each element in the array is an Object
instance representing the values that have been set. The order of these values in the array is determined by the int
(the first parameter) passed to the setter method. The values in the array are the values (the second parameter) passed to the setter method. In other words, the first element in the array is the value to be set for the first placeholder parameter in the RowSet
object's command. The second element is the value to be set for the second placeholder parameter, and so on.
Several setter methods send the driver and DBMS information beyond the value to be set. When the method getParams
is called after one of these setter methods has been used, the elements in the array will themselves be arrays to accommodate the additional information. In this category, the method setNull
is a special case because one version takes only two parameters (setNull(int parameterIndex, int SqlType)
). Nevertheless, it requires an array to contain the information that will be passed to the driver and DBMS. The first element in this array is the value to be set, which is null
, and the second element is the int
supplied for sqlType, which indicates the type of SQL value that is being set to null
. This information is needed by some DBMSs and is therefore required in order to ensure that applications are portable. The other version is intended to be used when the value to be set to null
is a user-defined type. It takes three parameters (setNull(int parameterIndex, int sqlType, String typeName)
) and also requires an array to contain the information to be passed to the driver and DBMS. The first two elements in this array are the same as for the first version of setNull
. The third element, typeName, gives the SQL name of the user-defined type. As is true with the other setter methods, the number of the placeholder parameter to be set is indicated by an element's position in the array returned by getParams
. So, for example, if the parameter supplied to setNull
is 2
, the second element in the array returned by getParams
will be an array of two or three elements.
Some methods, such as setObject
and setDate
have versions that take more than two parameters, with the extra parameters giving information to the driver or the DBMS. For example, the methods setDate
, setTime
, and setTimestamp
can take a Calendar
object as their third parameter. If the DBMS does not store time zone information, the driver uses the Calendar
object to construct the Date
, Time
, or Timestamp
object being set. As is true with other methods that provide additional information, the element in the array returned by getParams
is an array instead of a simple Object
instance.
The methods setAsciiStream
, setBinaryStream
, setCharacterStream
, and setUnicodeStream
(which is deprecated, so applications should use getCharacterStream
instead) take three parameters, so for them, the element in the array returned by getParams
is also an array. What is different about these setter methods is that in addition to the information provided by parameters, the array contains one of the BaseRowSet
constants indicating the type of stream being set.
NOTE: The method getParams
is called internally by RowSet
implementations extending this class; it is not normally called by an application programmer directly.
BaseRowSet
class provides the event notification mechanism for rowsets. It contains the field listeners
, methods for adding and removing listeners, and methods for notifying listeners of changes. A listener is an object that has implemented the RowSetListener
interface. If it has been added to a RowSet
object's list of listeners, it will be notified when an event occurs on that RowSet
object. Each listener's implementation of the RowSetListener
methods defines what that object will do when it is notified that an event has occurred.
There are three possible events for a RowSet
object:
RowSet
object are changed The BaseRowSet
method used for the notification indicates the type of event that has occurred. For example, the method notifyRowChanged
indicates that a row has been updated, deleted, or inserted. Each of the notification methods creates a RowSetEvent
object, which is supplied to the listener in order to identify the RowSet
object on which the event occurred. What the listener does with this information, which may be nothing, depends on how it was implemented.
BaseRowSet
object is initialized with many starting values. The following is true of a default RowSet
instance that extends the BaseRowSet
class: RowSet
object's command. BINARY
, VARBINARY
, LONGVARBINARY
, CHAR
, VARCHAR
, and LONGVARCHAR
. null
. Vector
object for storing the values set for the placeholder parameters in the RowSet
object's command. If other values are desired, an application must set the property values explicitly. For example, the following line of code sets the maximum number of rows for the CachedRowSet
object crs to 500.
crs.setMaxRows(500);Methods implemented in extensions of this
BaseRowSet
class must throw an SQLException
object for any violation of the defined assertions. Also, if the extending class overrides and reimplements any BaseRowSet
method and encounters connectivity or underlying data source issues, that method may in addition throw an SQLException
object for that reason.Modifier and Type | Field | Description |

object except one with a length of 0
(an empty string). Setting the Url property is optional if connections are established using a DataSource
object instead of the DriverManager

RowSet
object to the given number of rows. The fetch size gives a JDBC technology-enabled driver ("JDBC driver") a hint as to the number of rows that should be fetched from the database when more rows are needed for this RowSet
object. If the fetch size specified is zero, the driver ignores the value and is free to make its own best guess as to what the fetch size should be. A RowSet
object inherits the default properties of the ResultSet
object from which it got its data. That ResultSet
object's default fetch size is set by the Statement
object that created it.
This method applies to a RowSet
object only while it is connected to a database using a JDBC driver. For connected RowSet
implementations such as JdbcRowSet
, this method has a direct and immediate effect on the underlying JDBC driver.
A RowSet
object may use this method at any time to change its setting for the fetch size.
For RowSet
implementations such as CachedRowSet
, which operate in a disconnected environment, the SyncProvider
object being used may leverage the fetch size to poll the data source and retrieve a number of rows that do not exceed the fetch size and that may form a subset of the actual rows returned by the original query. This is an implementation variance determined by the specific SyncProvider
object employed by the disconnected RowSet
object.

parameter, the name is the type name of the referenced type. If a JDBC technology-enabled driver does not need the type code or type name information, it may ignore it.
If the parameter does not have a user-defined or REF

object that is the command for a RowSet
implementation extending the BaseRowSet
class. Each element in the array that is returned is an Object
instance that contains the values of the parameters supplied to a setter method. The order of the elements is determined by the value supplied for parameterIndex. If the setter method takes only the parameter index and the value to be set (possibly null), the array element will contain the value to be set (which will be expressed as an Object
). If there are additional parameters, the array element will itself be an array containing the value to be set plus any additional parameter values supplied to the setter method. If the method sets a stream, the array element includes the type of stream being supplied to the method. These additional parameters are for the use of the driver or the DBMS and may or may not be used.
NOTE: Stored parameter values of types Array
, Blob
, Clob
and Ref
are returned as SerialArray
, SerialBlob
, SerialClob
and SerialRef
respectively.

. This version of the method setNull
should be used for user-defined types and REF type parameters. Examples of user-defined types 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 user-defined or REF parameter. In the case of a user-defined type 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 user-defined 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 given typeName is ignored.

reads the data till end-of-file is reached. The driver does the necessary conversion from Java character format to the national character set in the database. Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.
Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setNCharacterStream
which takes a length parameter.
parameterName
- the name of the parametervalue
- the parameter valueSQLException
- 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

java.sql.NClob
object. The object implements the java.sql.NClob
interface. This NClob
object maps to a SQL NCLOB

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

SQLFeatureNotSupportedException
- if the JDBC driver does not support this methodpublic void setNClob(int parameterIndex, Reader reader, long length) throws SQLException
Reader
object. The reader must contain the number of characters specified by length otherwise a SQLException
will be generated when the PreparedStatement
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
