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
