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:
BigDecimal sal = new BigDecimal("153833.00");
PreparedStatement pstmt = con.prepareStatement("UPDATE EMPLOYEES
SET SALARY = ? WHERE ID = ?");
pstmt.setBigDecimal(1, sal);
pstmt.setInt(2, 110592);

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 database- 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.

PreparedStatement
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
. The execute
method returns a boolean
to 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).

void setNull(int parameterIndex, int sqlType, String typeName) throws SQLException
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.
