{The ISQLParam interface is used to provide access to each parameter in a |

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 |

conversion is possible. |

|
| 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. |
