DbExpressionBuilder.OuterApply Method

Definition

Namespace:

System.Data.Entity.Core.Common.CommandTrees.ExpressionBuilder

Assembly:

EntityFramework.dll

Overloads

OuterApply(DbExpression, Func<DbExpression,KeyValuePair<String,DbExpression>>)	Creates a new DbApplyExpression that evaluates the given apply expression once for each element of a given input set, producing a collection of rows with corresponding input and apply columns. Rows for which apply evaluates to an empty set have an apply column value of null.
OuterApply(DbExpressionBinding, DbExpressionBinding)	Creates a new DbApplyExpression that evaluates the given apply expression once for each element of a given input set, producing a collection of rows with corresponding input and apply columns. Rows for which apply evaluates to an empty set have an apply column value of null.

OuterApply(DbExpression, Func<DbExpression,KeyValuePair<String,DbExpression>>)

Public Function OuterApply (source As DbExpression, apply As Func(Of DbExpression, KeyValuePair(Of String, DbExpression))) As DbApplyExpression

Parameters

source

DbExpression

A DbExpression that specifies the input set.

apply

Func<DbExpression,KeyValuePair<String,DbExpression>>

A method that specifies the logic to evaluate once for each member of the input set.

Returns

DbApplyExpression

An new DbApplyExpression with the specified input and apply bindings and an DbExpressionKind of OuterApply.

Attributes

SuppressMessageAttribute

Exceptions

ArgumentNullException

The result of apply contains a name or expression that is null.

ArgumentException

The result of apply contains a name or expression that is not valid in an expression binding.

OuterApply(DbExpressionBinding, DbExpressionBinding)

Public Function OuterApply (input As DbExpressionBinding, apply As DbExpressionBinding) As DbApplyExpression

Parameters

input

DbExpressionBinding

An DbExpressionBinding that specifies the input set.

apply

DbExpressionBinding

An DbExpressionBinding that specifies logic to evaluate once for each member of the input set.

Returns

DbApplyExpression

An new DbApplyExpression with the specified input and apply bindings and an DbExpressionKind of OuterApply.

Exceptions

ArgumentNullException

input or apply is null.
