| RebuildResultSchema() | Validates and updates the result schema available on the client after query execution (it can be accessed using the SqlDataSource.Result property). This command does not affect the actual database schema on the server. |
| RebuildResultSchema(IEnumerable<IParameter>) | Validates and updates the result schema available on the client after query execution with the specified parameters (the result schema can be accessed using the SqlDataSource.Result property). This command does not affect the actual database schema on the server. |
| RebuildResultSchema(Predicate<IEnumerable<SqlQuery>>, IEnumerable<IParameter>, IEnumerable<SqlQuery>) | Validates and updates the result schema available on the client with the specified queries and parameters after confirming the execution of associated queries (the result schema can be accessed using the SqlDataSource.Result property).
