public interface PreparedStatement extends Statement
A SQL statement is precompiled and stored in a
PreparedStatement
object. This object can then be used to
efficiently execute this statement multiple times.
Note: The setter methods (setShort
, setString
,
and so on) for setting IN parameter values
must specify types that are compatible with the defined SQL type of
the input parameter. For instance, if the IN parameter has SQL type
INTEGER
, then the method setInt
should be used.
If arbitrary parameter type conversions are required, the method
setObject
should be used with a target SQL type.
In the following example of setting a parameter, con
represents
an active connection:
PreparedStatement pstmt = con.prepareStatement("UPDATE EMPLOYEES SET SALARY = ? WHERE ID = ?"); pstmt.setBigDecimal(1, 153833.00) pstmt.setInt(2, 110592)

In general, parameter values remain in force for repeated use of a

void setObject(int parameterIndex, Object x) throws SQLException
Sets the value of the designated parameter using the given object.
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
, RowId
, SQLXML
or Array
, the driver should pass it to the database as a
value of the corresponding SQL type.
Note: Not all databases allow for a non-typed Null to be sent to
the backend. For maximum portability, the setNull
or the
setObject(int parameterIndex, Object x, int sqlType)
method should be used
instead of setObject(int parameterIndex, Object x)
.
Note: 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.

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.
