Most dialects use the SQL function length( str ) to get the length of a string. SqlServer and Sybase use len( str ) instead.

org.hibernate.test.subselectfetch.SubselectFetchWithFormulaTest fails using SqlServer and Sybase.

I'll add a new test SubselectFetchWithFormulaTransactSqlTest to be used for SqlServer and Sybase (which extend AbstractTransactSQLDialect).
