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. |
