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
.
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

ResultSetMetaData
object that contains information about the columns of the
ResultSet
object that will be returned when this PreparedStatement
object is executed.
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.

public void clearParameters()
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
.
public void close() throws SQLException
MySQLStatement
Statement
object's database and JDBC resources immediately instead of waiting for this
to happen when it is automatically closed. It is generally good practice to release resources as soon as you are
finished with them to avoid tying up database resources.
Calling the method close
on a Statement
object that is already closed has no effect.
Note:When a Statement
object is closed, its current ResultSet
object, if one
exists, is also closed.close
