re multiple usage (Using Common Table Expressions)
Multiple usage works when used in the same query; multiple queries in the same statement can't re-use it. $0$0 $0 $0This is a big limitation, granted, but the documentation is correct.$0

Example Use of SqlHelpers TranslateVBLikePattern Shared Method (SqlHelpers.TranslateVBLikePattern Method (System.Data.Linq.SqlClient))
Example Use: Private Function LinqToSqlVbLikeMatch(ByVal pattern AsString) As List(Of Customer) ' Use the SqlHelpers TranslatedVBLikePattern shared method to create a pattern ' to pass into a SqlMethods.Like call. Dim vbPattern AsString = SqlHelpers.TranslateVBLikePattern(pattern, "") ' Use the VB Like pattern in a Linq to Sql call to the SqlMethods.Li
