RowSet

addRowSetListener

 public abstract void addRowSetListener (RowSetListener listener)

Registers the given listener so that it will be notified of events that occur on this RowSet object.

clearParameters

 public abstract void clearParameters ()

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.

execute

 public abstract void execute ()

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.

getCommand

 public abstract String getCommand ()

Retrieves this RowSet object's command property. The command property contains a command string, which must be an SQL query, that can be executed to fill the rowset with data. The default value is null.

getDataSourceName

 public abstract String getDataSourceName ()

Retrieves the logical name that identifies the data source for this RowSet object.

getEscapeProcessing

getMaxFieldSize

 public abstract int getMaxFieldSize ()

Retrieves the maximum number of bytes that may be returned for certain column values. This limit applies only to BINARY, VARBINARY, LONGVARBINARYBINARY, CHAR, VARCHAR, LONGVARCHAR, NCHAR and NVARCHAR columns. If the limit is exceeded, the excess data is silently discarded.

getMaxRows

 public abstract int getMaxRows ()

Retrieves the maximum number of rows that this RowSet object can contain. If the limit is exceeded, the excess rows are silently dropped.

getPassword

 public abstract String getPassword ()

Retrieves the password used to create a database connection. The password property is set at run time before calling the method execute. It is not usually part of the serialized state of a RowSet object.

getUrl

 public abstract String getUrl ()

Retrieves the url property this RowSet object will use to create a connection if it uses the DriverManager instead of a DataSource object to establish the connection. The default value is null.

getUsername

 public abstract String getUsername ()

Retrieves the username used to create a database connection for this RowSet object. The username property is set at run time before calling the method execute. It is not usually part of the serialized state of a RowSet object.

isReadOnly

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.

setObject

 public abstract void setObject (String parameterName, Object x, int targetSqlType, int scale)

Sets the value of the designated parameter with the given object. The second argument must be an object type; for integral values, the java.lang equivalent objects should be used.

The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface SQLData), the JDBC driver should call the method SQLData.writeSQL to write it to the SQL 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.

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

setObject

 public abstract void setObject (int parameterIndex, Object x, int targetSqlType, int scaleOrLength)

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.

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

setObject

 public abstract void setObject (int parameterIndex, Object x)

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, 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.

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.

setObject

 public abstract void setObject (String parameterName, Object x, int targetSqlType)

Sets the value of the designated parameter with the given object. This method is like the method setObject above, except that it assumes a scale of zero.

setObject

 public abstract void setObject (int parameterIndex, Object x, int targetSqlType)

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.

setObject

 public abstract void setObject (String parameterName, Object x)

Sets the value of the designated parameter with the given object. The second parameter must be of type Object; therefore, the java.lang equivalent objects should be used for built-in types.

The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument will be converted to the corresponding SQL type before being sent 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 the interface SQLData, the JDBC driver should call the method SQLData.writeSQL to write it to the SQL 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.

This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.

setPassword

 public abstract void setPassword (String password)

Sets the database password for this RowSet object to the given String.

setQueryTimeout

 public abstract void setQueryTimeout (int seconds)

Sets the maximum time the driver will wait for a statement to execute to the given number of seconds. If this limit is exceeded, an SQLException is thrown.

setReadOnly

 public abstract void setReadOnly (boolean value)

Sets whether this RowSet object is read-only to the given boolean.

setRef

 public abstract void setRef (int i, Ref x)

Sets the designated parameter in this RowSet object's command with the given Ref value. The driver will convert this to the appropriate REF(<structured-type>) value.

setRowId

 public abstract void setRowId (int parameterIndex, RowId x)

Sets the designated parameter to the given java.sql.RowId object. The driver converts this to a SQL ROWID value when it sends it to the database

setRowId

 public abstract void setRowId (String parameterName, RowId x)

Sets the designated parameter to the given java.sql.RowId object. The driver converts this to a SQL ROWID when it sends it to the database.

setSQLXML

 public abstract void setSQLXML (int parameterIndex, SQLXML xmlObject)

Sets the designated parameter to the given java.sql.SQLXML object. The driver converts this to an SQL XML value when it sends it to the database.

setSQLXML

 public abstract void setSQLXML (String parameterName, SQLXML xmlObject)

Sets the designated parameter to the given java.sql.SQLXML object. The driver converts this to an SQL XML value when it sends it to the database.

setShort

 public abstract void setShort (int parameterIndex, short x)

Sets the designated parameter in this RowSet object's command to the given Java short value. The driver converts this to an SQL SMALLINT value before sending it to the database.

setShort

 public abstract void setShort (String parameterName, short x)

Sets the designated parameter to the given Java short value. The driver converts this to an SQL SMALLINT value when it sends it to the database.

setString

 public abstract void setString (String parameterName, String x)

Sets the designated parameter to the given Java String value. The driver converts this to an SQL VARCHAR or LONGVARCHAR value (depending on the argument's size relative to the driver's limits on VARCHAR values) when it sends it to the database.

setString

 public abstract void setString (int parameterIndex, String x)

Sets the designated parameter in this RowSet object's command to the given Java String value. Before sending it to the database, the driver converts this to an SQL VARCHAR or LONGVARCHAR value, depending on the argument's size relative to the driver's limits on VARCHAR values.

setTime

 public abstract void setTime (String parameterName, Time x, Calendar cal)

Sets the designated parameter to the given java.sql.Time value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIME value, which the driver then sends to the database. With a a Calendar object, the driver can calculate the time taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.

setTime

 public abstract void setTime (int parameterIndex, Time x, Calendar cal)

Sets the designated parameter in this RowSet object's command with the given java.sql.Time value. The driver will convert this to an SQL TIME value, using the given java.util.Calendar object to calculate it, before sending it to the database.

setTime

 public abstract void setTime (String parameterName, Time x)

Sets the designated parameter to the given java.sql.Time value. The driver converts this to an SQL TIME value when it sends it to the database.

setTime

 public abstract void setTime (int parameterIndex, Time x)

Sets the designated parameter in this RowSet object's command to the given java.sql.Time value. The driver converts this to an SQL TIME value before sending it to the database, using the default java.util.Calendar to calculate it.

setTimestamp

 public abstract void setTimestamp (int parameterIndex, Timestamp x, Calendar cal)

Sets the designated parameter in this RowSet object's command with the given java.sql.Timestamp value. The driver will convert this to an SQL TIMESTAMP value, using the given java.util.Calendar object to calculate it, before sending it to the database.

setTimestamp

 public abstract void setTimestamp (String parameterName, Timestamp x, Calendar cal)

Sets the designated parameter to the given java.sql.Timestamp value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIMESTAMP value, which the driver then sends to the database. With a a Calendar object, the driver can calculate the timestamp taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.
