Sets the designated parameter to the given Ref object in the Java programming language. The driver converts this to an SQL REF value when it sends it to the database. Internally, the Ref is represented as a SerialRef to ensure serializability.

The parameter value set by this method is stored internally and will be supplied as the appropriate parameter in this RowSet object's command when the method execute is called. Methods such as execute and populate must be provided in any class that extends this class and implements one or more of the standard JSR-114 RowSet interfaces.

NOTE: JdbcRowSet does not require the populate method as it is undefined in this class.

After this method has been called, a call to the method getParams will return an object array of the current command parameters, which will include the Ref object set for placeholder parameter number parameterIndex. Note that because the numbering of elements in an array starts at zero, the array element that corresponds to placeholder parameter number parameterIndex is element number parameterIndex -1.

Parameters:

parameterIndex the ordinal number of the placeholder parameter in this RowSet object's command that is to be set. The first parameter is 1, the second is 2, and so on; must be 1 or greater

ref a Ref object representing an SQL REF value; cannot be null

Exceptions:

SQLException if an error occurs; the parameter index is out of bounds or the Ref object is null; or the Ref object returns a null base type name.

`parameterIndex`		the ordinal number of the placeholder parameter in this `RowSet` object's command that is to be set. The first parameter is 1, the second is 2, and so on; must be `1` or greater
`ref`		a `Ref` object representing an SQL `REF` value; cannot be null
