SQLFire SQL types are mapped to corresponding values in the SQLFType enumeration.

Also listed are the corresponding mapping of the ADO.NET's System.Data.DbType enumeration type and the corresponding .NET type of the object that will be returned by default in query results or that should be passed as parameter values for a column or expression having that SQL type.

Additional information about the SQL types and their mapping to the ADO.NET API is described in SQLFire Data Types in ADO.NET.
