| |
AsNestedTResult |

| |
AsSingleColumn |

| |
AsSubQuery |

| |
AsValue |

(Inherited from IQueryObjectWithValue.) | |
Changed |
Marks the object as changed
(Inherited from IQueryObject.) | |
CloneObject |
Creates the clone of the object.
(Inherited from IQueryObject.) | |
CopyPropertiesTo |

(Inherited from IQueryParameters.) | |
EnsureParameters |

(Inherited from IQueryParameters.) | |
Execute |
Executes the current query and returns it's results as a DataSet.
| |
ExecuteReader |
Executes the current query and returns it's results as an IDataReader. The SupportsReader flag indicates whether this operation
is supported.
| |
ExecuteReaderAsync |
Asynchronously executes the current query and returns it's results as an IDataReader. The SupportsReader flag indicates whether this operation
is supported.
| |
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.
| |
GetCompleteQueryParameters |
Returns query parameter container filled with the complete settings of current query.
| |
GetCompleteSettings |
Gets the complete parameters for the query execution
| |
GetEnumerableResult |
Gets an enumeration of data records representing the result of this query.
| |
GetEnumerableResultAsync |
Asynchronously gets an enumeration of data records representing the result of this query.
| |
GetExecutingQuery |
Gets the query to execute against database
| |
GetExpression |
Gets a string expression representing this object
(Inherited from IQueryObjectWithValue.) | |
GetFullQueryText |

| |
GetListResultT |
Gets the result as a list of values from the first column that the query returns. Excludes null values from the result.

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.) | |
SelectT |
Transforms the current result
| |
ToString |
Returns the string representation of the expression, with possibility of expanding parameters
