629    {The ISQLParam interface is used to provide access to each parameter in a
630 <   parametised SQL Statement. It subclasses IColumnMetaData and this part of
625 <   the interface may be used to access information on the expected SQL Type, etc.
626 <
627 <   It also subclasses ISQLData and this part of the interface may be used to access
628 <   current values for each parameter.
629 <
630 <   Otherwise, the interface comprises the Setter Methods and properties used to

631     set the value of each parameter.
632  
633     Automatic conversion is provided to and from strings. That is GetAsString and
634     SetAsString are safe to use for sql types other than boolean - provided automatic
635     conversion is possible.
636 +
637 +   ISQLParam is subclassed from the IParamMetaData interface. This interface provides
638 +   access to the parameter metadata. This metadata is mutable and can change after
639 +   a parameter is set to a given value. This is acceptable as long as the parameter
640 +   metadata is type compatible with the underlying column metadata and hence the
641 +   parameter value can be converted by Firebird into a value acceptable by the
642 +   underlying column. The column metadata, which is unmutable, can be obtained
643 +   by the ISQLParam.getColMetadata interface. When a statement is prepared, the
644 +   parameter metadata is always initialised to the column metadata.
