Parameters: statement The PreparedStatement that we are wrapping
PreparedStatement
object's
batch of commands.
Throws: SQLException if a database access error occurs
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
execute
method handles these complex
statements as well as the simpler form of statements handled by the
methods executeQuery
and executeUpdate
.
Returns: Unknown

Parameters: i the first parameter is 1, the second is 2, ... x an Array
object that maps an SQL ARRAY
value
Throws: SQLException if a database access error occurs
Since: 1.2
LONGVARCHAR
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.
Parameters: parameterIndex the first parameter is 1, the second is 2, ... x the Java input stream that contains the ASCII parameter value length the number of bytes in the stream
Throws: SQLException if a database access error occurs

or LONGVARBINARY
(depending on the argument's size relative to the driver's limits on
VARBINARY
values) when it sends it to the database.
Parameters: parameterIndex the first parameter is 1, the second is 2, ... x the parameter value
Throws: SQLException if a database access error occurs
Reader
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.
Parameters: parameterIndex the first parameter is 1, the second is 2, ... reader the java reader which contains the UNICODE data length the number of characters in the stream

value. The
driver converts this to an SQL DATE
value when it sends it
to the database.
Parameters: parameterIndex the first parameter is 1, the second is 2, ... x the parameter value
Throws: SQLException if a database access error occurs
java.sql.Date
value, 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
object, the driver can calculate the date 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.

driver converts this to an SQL FLOAT
value when it sends it
to the database.
Parameters: parameterIndex the first parameter is 1, the second is 2, ... x the parameter value
Throws: SQLException if a database access error occurs
int
value. The
driver converts this to an SQL INTEGER
value when it sends
it to the database.
Parameters: parameterIndex the first parameter is 1, the second is 2, ... x the parameter value

NULL
. 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: paramIndex 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
Since: 1.2
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
value
Throws: SQLException if a database access error occurs
Since: 1.2
short
value. The
driver converts this to an SQL SMALLINT
value when it sends
it to the database.
Parameters: parameterIndex the first parameter is 1, the second is 2, ... x the parameter value
Throws: SQLException if a database access error occurs
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.
Parameters: parameterIndex the first parameter is 1, the second is 2, ... x the parameter value
Throws: SQLException if a database access error occurs
java.sql.Time
value. The
driver converts this to an SQL TIME
value when it sends it
to the database.
Parameters: parameterIndex the first parameter is 1, the second is 2, ... x the parameter value
Throws: SQLException if a database access error occurs
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.
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
Since: 1.2
java.sql.Timestamp
value. The driver converts this to an SQL TIMESTAMP
value
when it sends it to the database.
Parameters: parameterIndex the first parameter is 1, the second is 2, ... x the parameter value
Throws: SQLException if a database access error occurs
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.
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 timestamp
Throws: SQLException if a database access error occurs
Since: 1.2
Deprecated:
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
Throws: SQLException if a database access error occurs
java.net.URL
value.
The driver converts this to an SQL DATALINK
value
when it sends it to the database.
Parameters: parameterIndex the first parameter is 1, the second is 2, ... x the java.net.URL
object to be set
Throws: SQLException if a database access error occurs
