Ensures data parameters for the given query
(Inherited from IQueryParameters.) |
![]() | Execute |
Executes the current query and returns it's results as a DataSet
(Inherited from IDataQuery.) |
![]() | ExecuteReader |
Executes the current query and returns it's results as a data reader
(Inherited from IDataQuery.) |
![]() | Expand |
Expands the expression by replacing parameters with their values
(Inherited from IQueryParameters.) |
![]() | ForEachRow |
Executes the given action for each item (DataRow) in the result. Processes the items in batches of the given size.
(Inherited from IDataQuery.) |
![]() | GetCompleteSettings |
Gets the complete parameters for the query execution
(Inherited from IDataQuery.) |
![]() | GetExpression |
Gets a string expression representing this object
(Inherited from IQueryObjectWithValue.) |
![]() | GetFullQueryText |

(Inherited from IQueryObject.) |
![]() | IncludeDataParameters |
Adds the data parameters to the current query parameters
(Inherited from IQueryObject.) |
![]() | ReturnNoResults |
Sets the query to return no results. This action is irreversible, once the query is set to return no results it cannot be changed.
This method is used by data engine to forbid access to data that are not allowed to be accessed (e.g. license limitations), without notifying the process about the fact.
(Inherited from IWhereCondition.) |
![]() | Select T |
Transforms the current result
(Inherited from IDataQuery.) |
![]() | ToString |
Returns the string representation of the expression, with possibility of expanding parameters
(Inherited from IQueryParameters.) |
