Dynamic LINQ - Knowledge Base (KB)

LOWER and REPLACE doesn't work on dynamic linq where statement

Here is my code , ...db.myDBContext.my_tables.Where("REPLACE(LOWER(name),\" \",\"\") == \"{0}\"", value); ...it show the error ...No applicable method 'LOWER' exists in type 'my_table' ...can't I use ...REPLACE... and ...LOWER... in dynamic linq clause ...
