public interface PreparedStatement
An object that represents a precompiled SQL 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)
Connection.prepareStatement(java.lang.String)

Types
void setObject(int parameterIndex, Object x) throws SQLException
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
, 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.

boolean execute() throws SQLException
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).
true

void setCharacterStream(int parameterIndex, Reader reader, int length) throws SQLException
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.

ResultSetMetaData getMetaData() throws SQLException
ResultSetMetaData
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.

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.

void setBlob(int parameterIndex, InputStream inputStream, long length) throws SQLException
InputStream
object. The inputstream must contain the number of characters specified by length otherwise a SQLException
will be generated when the PreparedStatement
is executed. This method differs from the setBinaryStream (int, InputStream, int)
method because it informs the driver that the parameter value should be sent to the server as a BLOB
. When the setBinaryStream
method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARBINARY
or a BLOB

Reader
object. The reader must contain the number of characters specified by length otherwise a SQLException
will be generated when the PreparedStatement
is executed. This method differs from the setCharacterStream (int, Reader, int)
method because it informs the driver that the parameter value should be sent to the server as a NCLOB

void setObject(int parameterIndex, Object x, int targetSqlType, int scaleOrLength) throws SQLException
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. If the second argument is an InputStream
then the stream must contain the number of bytes specified by scaleOrLength. If the second argument is a Reader
then the reader must contain the number of characters specified by scaleOrLength. If these conditions are not true the driver will generate a SQLException
when the prepared statement is executed.
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
, NClob
, Struct
, java.net.URL
, 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.
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.
scaleOrLength
- for java.sql.Types.DECIMAL
or java.sql.Types.NUMERIC types
, this is the number of digits after the decimal point. For Java Object types InputStream
and Reader
, this is the length of the data in the stream or reader. For all other types, this value will be ignored.
SQLException
- if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs; this method is called on a closed PreparedStatement
or if the Java Object specified by x is an InputStream or Reader object and the value of the scale parameter is less than zero
