Initializes a new instance of the QuerySpec class. Copy ctor

Initializes a new instance of the QuerySpec class.

Initializes a new instance of the QuerySpec class.

Gets or sets the alias.

Gets or sets the optional custom function mapping store. A custom function mapping store takes precedence over the function mapping store obtained from the Dynamic Query Engine (DQE) used for producing the SQL for the query. If a custom function mapping store is needed for a query, set this property only on the query object passed to the execution method. No need to set it on inner query objects.

Gets a value indicating whether this instance is prepared.

Gets the nested queries defined for this query. By default this is an empty list, and only filled with nested queries if this query is a dynamic query and it contains one or more nested queries

Gets or sets the call back lambda which is called after this query has been prepared for execution. Use this method to tap into the execution chain to do last-minute query object manipulation / inspection prior to the actual fetch action.

Gets the last clause on the from clause set list or null if nothing is there. Used with unwrapping tvf calls.

Gets the type of the resultset element.

Gets the target alias.

Gets or sets a value indicating whether the 'Alias' value should be used only for the query's alias (true) or for target aliasing as well if there's no target alias set (false, default). Set to true when the query is converted to a derived table.

Prepares the implementor by converting it to a relation object and adds it to the passed in relationcollection.

Adds the field to projection if not present already. Uses field alias checks. If this query is an entity query, it won't add any fields, only verify whether the field is present.

Appends the predicate with And to the prepared where clause. Only used for appending additional filters to specified filters.

Assures that the query has a proper alias. This is necessary for derived table generation, as derived tables need an alias.

Coerces this query to a scalar query expression

Converts this instance to a dynamic relation operand.

Determines if the derived table variant of this query is the target when this query is used as the target of a field compare set predicate. Only true if query is an entity query and entity is an inheritance entity of TargetPerEntity.

Determines if wrapping as derived table is required for scalar query. This overload looks at the prepared elements, and if a wrapping is required it will return true, otherwise false.

Determines the real target alias to use.

Determines the type of the resultset. This type is used to build resultset instances for hierarchy fetches.

Gets the Type of the current instance.

Gets the where as string.

Handles the unwrap TVF call action.

Determines whether this instance is empty.

Makes this query as being not prepared so it will be re-prepared the next time Prepare() is called.

Creates a shallow copy of the current Object.

Called when PrepareForExecution has been completed successfully. Calls the lambda set in OnPrepareForExecutionCallBack, if set.

Prepares the contents of this query to be executed.

Prepares this query for execution.

Raises an exception if a QueryTarget was used in a query type which wasn't suitable for that. By default it does this
