QuerySpec Methods |
The QuerySpec type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | AddAsRelation |
Prepares the implementor by converting it to a relation object and adds it to the passed in relationcollection.
|
| AddFieldToProjectionIfNotPresent |
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.
|
| AddFromClauseDirective |
Adds from clause directive.
|
| AddFromClauseDirectives |
Adds from clause directives.
|
| AppendToPreparedWhereClauseWithAnd |
Appends the predicate with And to the prepared where clause. Only used for appending additional filters to specified filters.
|
| AppendUnionedQueriesToDerivedTable |
Converts all unioned queries to derived tables and appends them as unioned queries to the derived table specified.
|
| AssureAlias |
Assures that the query has a proper alias. This is necessary for derived table generation, as derived tables need an alias.
|
| CoerceToScalarQuery |
Coerces this query to a scalar query expression
|
| ConvertToDynamicRelationOperand |
Converts this instance to a dynamic relation operand.
|
| DetermineIfDerivedTableIsTargetInFieldCompareSetPredicate |
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.
|
| DetermineIfWrappingAsDerivedTableIsRequiredForScalarQuery |
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.
|
| DetermineIfWrappingAsDerivedTableIsRequiredForScalarQuery(AggregateFunction) |
Determines if wrapping as derived table is required for scalar query.
|
| DetermineRealTargetAliasToUse |
Determines the real target alias to use.
|
| DetermineResultsetType |
Determines the type of the resultset. This type is used to build resultset instances for hierarchy fetches.
|
 | Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Field |
Creates a field which targets the projection of this query. Use this to easily create a derived table targeting field which targets this query.
|
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetAdditionalInfoAsString |
Gets the additional info as string. For ToString().
|
| GetAllFieldsFromProjection |
Gets all fields from projection.
|
| GetFromAsString |
Gets from as string.
|
| GetFromClauseDirectiveClones |
Gets from clause directives as clones.
|
| GetGroupByAsString |
Gets the group by as string.
|
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetHavingAsString |
Gets the having as string.
|
| GetOrderByAsString |
Gets the order by as string.
|
| GetPrefetchPathAsString |
Gets the prefetch path as string.
|
| GetProjectionAsEntityFields |
Gets the projection as EntityFields object
|
| GetProjectionAsEntityFields2 |
Gets the projection as EntityFields2 object
|
| GetProjectionAsString |
Gets the projection as string.
|
| GetQueryParameters |
Gets the query parameters, built from the elements for the query inside this expression
|
| GetReplacementForQueryTarget |
Gets the replacement for query target. By default this is the result of GetThisAsEmptyClone(). It will thrown an exception if
the class isn't an entityquery, unless this method is overriden in a subtype.
|
| GetThisAsEmptyClone |
Gets the this as empty clone.
|
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GetWhereAsString |
Gets the where as string.
|
| HandleUnwrapTvfCall |
Handles the unwrap TVF call action.
|
| IsEmpty |
Determines whether this instance is empty.
|
| MarkAsNotPrepared |
Makes this query as being not prepared so it will be re-prepared the next time Prepare() is called.
|
| MarkAsPrepared |
Marks as prepared.
|
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| OnPreparedForExecution |
Called when PrepareForExecution has been completed successfully. Calls the lambda set in OnPrepareForExecutionCallBack, if set.
|
| Prepare |
Prepares the contents of this query to be executed.
|
| PrepareForExecution |
Prepares this query for execution.
|
| RaiseQueryTargetUsageExceptionIfApplicable |
Raises an exception if a QueryTarget was used in a query type which wasn't suitable for that. By default it does this
|
| ReplacePlaceHolders |
Replaces the EntityQueryPlaceHolder objects with this instance
|
| SetCorrelationPredicate |
Sets the correlation predicate.
|
| SetTargetAlias |
Sets the target alias.
|
| ToDerivedTable |
Converts this instance to a derived table definition.
|
| ToString |
Returns a String that represents this instance.
(Overrides ObjectToString.) |
| ToString(Int32) |
Returns a String that represents this instance.
|
| ValidateForUnion |
Validates this query whether it can be a unioned query in a parent query or not. Queries which contain nested queries or prefetch paths can't be unioned.
|
