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)

    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.

the name is the type name of the parameter itself.  For a REF

Throws:	SQLException – if a database access error occurs; this method is called on a closed `PreparedStatement` or the SQL statement does not return a `ResultSet` object SQLTimeoutException – when the driver has determined that the timeout value that was specified by the `setQueryTimeout` method has been exceeded and has at least attempted to cancel the currently running `Statement`
Returns:	a `ResultSet` object that contains the data produced by the query; never `null`
Params:	parameterIndex – the first parameter is 1, the second is 2, ... x – the parameter value
Throws:	SQLException – if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed `PreparedStatement`
Params:	parameterIndex – of the first parameter is 1, the second is 2, ... value – the parameter value
Throws:	SQLException – if parameterIndex does not correspond to a parameter marker in the SQL statement; if the driver does not support national character sets; if the driver can detect that a data conversion error could occur; if a database access error occurs; or this method is called on a closed `PreparedStatement` SQLFeatureNotSupportedException – if the JDBC driver does not support this method
Since:	1.6
Params:	parameterIndex – index of the first parameter is 1, the second is 2, ... reader – An object that contains the data to set the parameter value to. length – the number of characters in the parameter data.
Throws:	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 length specified is less than zero.
