Not In Opperator Using in EntityQuery

Not

   Here is an example:

Reversing a Condition with the Not Operator
This example introduces the EntityBooleanOp.NOT operator, which reverses the sense of a condition.  Like the OR operator, the NOT operator is applied after the clause to which it applies has been defined.

C#

#region Name Does ! (Contains the Letter 'E')
/// <remarks>
/// select * from "dbo"."Product" where (( not "dbo"."Product"."ProductName" like ?)) 
/// Params: v0=%E%
/// </remarks>
internal static RdbQuery GetQueryNameDoesNotContainsE() {
  RdbQuery query = new RdbQuery(typeof(Product));
  query.AddClause(Product.ProductNameEntityColumn, EntityQueryOp.Contains, "E");
  query.AddOperator(EntityBooleanOp.Not);
  return query;
}
#endregion

VB

#Region "Name Does NOT Contains the Letter 'E'"
  ''' <remarks>
  ''' select * from "dbo"."Product" where (( not "dbo"."Product"."ProductName" like ?)) 
  ''' Params: v0=%E%
  ''' </remarks>
  Friend Shared Function GetQueryNameDoesNotContainsE() As RdbQuery
    Dim query As New RdbQuery(GetType(Product))
    query.AddClause(Product.ProductNameEntityColumn, EntityQueryOp.Contains, "E")
    query.AddOperator(EntityBooleanOp.Not)
    Return query
  End Function
#End Region
