PreparedStatementjava.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 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.

PreparedStatementReader
object, which is the given number of characters long.
When a very large UNICODE value is input to a LONGVARCHAR
parameter, it may be more practical to send it via a
java.io.Reader object. The data will be read from the stream
as needed until end-of-file is reached. The JDBC driver will
do any necessary conversion from UNICODE to the database char format.
Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.
setCharacterStream in interface PreparedStatementSQLExceptionparameterIndex - the first parameter is 1, the second is 2, ...reader - the java.io.Reader object that contains the
Unicode datalength - the number of characters in the stream
public void setNull(int parameterIndex,

public void setNull(int paramIndex,
int sqlType,
String typeName)
throws SQLException
PreparedStatementNULL.
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.
setNull in interface PreparedStatementSQLExceptionparamIndex - the first parameter is 1, the second is 2, ...sqlType - a value from java.sql.TypestypeName - the fully-qualified name of an SQL user-defined type;
ignored if the parameter is not a user-defined type or REF

public boolean execute()
throws SQLException
PreparedStatementPreparedStatement object,
which may be any kind of SQL statement.
Some prepared statements return multiple results; the execute
method handles these complex statements as well as the simpler
form of statements handled by the methods executeQuery
and executeUpdate.

indicate the form of the first result. You must call either the method
getResultSet or getUpdateCount
to retrieve the result; you must call getMoreResults to
move to any subsequent result(s).

query; never null
public void setObject(int parameterIndex,
Object x,
int targetSqlType,
int scale)
throws SQLException
PreparedStatementSets 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, Struct,
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 database-specific abstract data types.
setObject in interface PreparedStatementSQLExceptionparameterIndex - the first parameter is 1, the second is 2, ...x - the object containing the input parameter valuetargetSqlType - the SQL type (as defined in java.sql.Types) to be
sent to the database. The scale argument may further qualify this type.scale - for java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types,
this is the number of digits after the decimal point. For all other
types, this value will be ignored.Types

setObject in interface PreparedStatementSQLExceptionparameterIndex - the first parameter is 1, the second is 2, ...x - the object containing the input parameter valuetargetSqlType - the SQL type (as defined in java.sql.Types) to be
sent to the database
public void setObject(int parameterIndex,
Object x)
throws SQLException
PreparedStatementSets the value of the designated parameter using 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, Struct,
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.
setObject in interface PreparedStatementSQLExceptionparameterIndex - the first parameter is 1, the second is 2, ...x - the object containing the input parameter value
public void setTimestamp(int parameterIndex,
Timestamp x)
throws SQLException
PreparedStatementjava.sql.Timestamp value.
The driver
converts this to an SQL TIMESTAMP value when it sends it to the
database.
setTimestamp in interface PreparedStatementSQLExceptionparameterIndex - the first parameter is 1, the second is 2, ...x - the parameter value
public void setTimestamp(int parameterIndex,
Timestamp x,
Calendar cal)
throws SQLException
PreparedStatementjava.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
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.
setTimestamp in interface PreparedStatementSQLExceptionparameterIndex - the first parameter is 1, the second is 2, ...x - the parameter valuecal - the Calendar object the driver will use
to construct the timestamp
public int executeUpdate()

which must be an SQL INSERT, UPDATE or
DELETE statement; or an SQL statement that returns nothing,
such as a DDL statement.

PreparedStatementLONGVARCHAR
parameter, it may be more practical to send it via a
java.io.InputStream. Data will be read from the stream
as needed until end-of-file is reached. The JDBC driver will
do any necessary conversion from ASCII to the database char format.
Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.
setAsciiStream in interface PreparedStatementSQLExceptionparameterIndex - the first parameter is 1, the second is 2, ...x - the Java input stream that contains the ASCII parameter valuelength - the number of bytes in the stream
public void setBinaryStream(int parameterIndex,

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.
setBinaryStream in interface PreparedStatementSQLExceptionparameterIndex - the first parameter is 1, the second is 2, ...x - the java input stream which contains the binary parameter valuelength - the number of bytes in the stream
public void clearParameters()
throws SQLException
PreparedStatementIn general, parameter values remain in force for repeated use of a
statement. 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; this can
be done by calling the method clearParameters.
clearParameters in interface PreparedStatementSQLException
public ResultSetMetaData getMetaData()
throws SQLException
PreparedStatementResultSetMetaData object that contains
information about the columns of the ResultSet object
that will be returned when this PreparedStatement object
is executed.
Because a PreparedStatement object is precompiled, it is
possible to know about the ResultSet object that it will
return without having to execute it. Consequently, it is possible
to invoke the method getMetaData on a
PreparedStatement object rather than waiting to execute
it and then invoking the ResultSet.getMetaData method
on the ResultSet object that is returned.
NOTE: Using this method may be expensive for some drivers due to the lack of underlying DBMS support.
getMetaData in interface PreparedStatementSQLException
ResultSet object's columns or
null if the driver cannot return a
ResultSetMetaData object
public void addBatch()
throws SQLException
PreparedStatementPreparedStatement
