Gets or sets the DbExpression that defines the left argument.
public:
property System::Data::Common::CommandTrees::DbExpression ^ Left { System::Data::Common::CommandTrees::DbExpression ^ get(); };public System.Data.Common.CommandTrees.DbExpression Left { get; }member this.Left : System.Data.Common.CommandTrees.DbExpressionPublic ReadOnly Property Left As DbExpressionProperty Value
The DbExpression that defines the left argument.
Exceptions
The expression is null.
The expression is not associated with the command tree of the DbBinaryExpression,
or its result type is not equal or promotable to the required type for the left argument.
Remarks
Derived expression types might perform stricter type checks when the Left property is set. For example, DbUnionAllExpression requires that its left expression has a collection result type, while DbAndExpression requires a Boolean result type. Typically, derived expression types will not allow Left to be set to an expression with a result type that is not equal or promotable to the result type of the current value.
