SelectExpression Class

Initializes a new instance of the SetExpression class.

Initializes a new instance of the SelectExpression class.

Gets or sets the Alias assigned to this set.

Gets or sets a value indicating whether the select allows duplicate rows (no distinct) or not (distinct).

Gets or sets the duration how long the cached resultset should stay in the cache.

Gets or sets a value indicating whether the resultset of this query has to be cached or not.

Gets or sets the tag the resultset should be cached under. By default this is the empty string (no tag)

Indicates that the node can be reduced to a simpler node. If this returns true, Reduce() can be called to produce the reduced form.

Gets or sets the AliasContainer which contains the aliases inside this direct set which are reachable only INSIDE this set. If null, it has no aliases directly inside this set, it can be the source might have contained aliases.

gets or sets the excludeincludefields expression for the select.

Gets or sets the filter for the select

Gets or sets a value indicating whether this instance is extraction locked, which means a where/orderby extractor won't touch it.

Gets the node type of this Expression.

Gets or sets a value indicating whether the cached resultset should be

Gets or sets the prefetch path definition.

Gets or sets the projection of the select

Flag which is set if this set requires a projection to be usable. This flag is later on used to determine if a projection has to be injected into the processing result of this set if there's none defined (true), or not (false). Default is false;

Gets or sets the number of rows to skip.

Gets or sets the number of rows to take. 0 == all rows

Gets or sets the sort expression to use in this select.

Gets or sets the source expression of the select

Gets the static type of the expression that this Expression represents.

Set of unioned queries with this set expression

Gets whether there are unioned queries in this query (true) or not (false)

Dispatches to the specific visit method for this node type. For example, MethodCallExpression calls the VisitMethodCall(MethodCallExpression).

Adds the sort clause.

Appends the query specified as a unioned query with the operator specified.

Assigns a new alias to this set, if necessary

Determines whether the specified object is equal to the current object.

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Serves as the default hash function.

Gets the Type of the current instance.

Handles this instance using the specified handler.

Creates a shallow copy of the current Object.

Merges the specified union list into the set expression's unionlist.

A new alias was set, using AssignNewAliasIfRequired. Use this method to map a wrapped expression to the alias set in the tracker passed in.

Reduces this node to a simpler expression. If CanReduce returns true, this should return a valid expression. This method can return another node which itself must be reduced.

Reduces this node to a simpler expression. If CanReduce returns true, this should return a valid expression. This method can return another node which itself must be reduced.

Reduces the expression to a known node type (that is not an Extension node) or just returns the expression if it is already a known type.

Sets the RequiresProjection flag if this expression isn't an EntityExpression

Returns a textual representation of the Expression.

Reduces the node and then calls the visitor delegate on the reduced expression. The method throws an exception if the node is not reducible.
