In 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
.
Throws: SQLException if a database access error occurs

using the given Calendar
object. The driver uses
the Calendar
object to construct an SQL DATE
value,
which the driver then sends to the database. With a
a Calendar

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.

Note: You must specify the parameter's SQL type.
Parameters: parameterIndex the first parameter is 1, the second is 2, ... sqlType the SQL type code defined in java.sql.Types
Throws: SQLException if a database access error occurs
NULL
.
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.
Parameters: parameterIndex the first parameter is 1, the second is 2, ... sqlType a value from java.sql.Types
typeName the fully-qualified name of an SQL user-defined type;
ignored if the parameter is not a user-defined type or REF
Throws: SQLException if a database access error occurs

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, 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 datatabase- specific abstract data types.
Parameters: parameterIndex the first parameter is 1, the second is 2, ... x the object containing the input parameter value targetSqlType 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.
Throws: SQLException if a database access error occurs

setObject
above, except that it assumes a scale of zero.
Parameters: parameterIndex the first parameter is 1, the second is 2, ... x the object containing the input parameter value targetSqlType the SQL type (as defined in java.sql.Types) to be sent to the database
Throws: SQLException if a database access error occurs
Sets 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, then 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.
Parameters: parameterIndex the first parameter is 1, the second is 2, ... x the object containing the input parameter value
Throws: SQLException if a database access error occurs
REF(<structured-type>)
value.
Parameters: i the first parameter is 1, the second is 2, ... x an SQL REF

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.

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.
Parameters: parameterIndex the first parameter is 1, the second is 2, ... x the parameter value cal the Calendar
object the driver will use
to construct the time
Throws: SQLException if a database access error occurs

Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large UNICODE value is input to aLONGVARCHAR
parameter, it may be more practical to send it via a
java.io.InputStream
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.
The byte format of the Unicode stream must be Java UTF-8, as
defined in the Java Virtual Machine Specification.
Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.
Parameters: parameterIndex the first parameter is 1, the second is 2, ... x the java input stream which contains the UNICODE parameter value length the number of bytes in the stream
