Signature de la méthode process_literal_param

def process_literal_param(self, value, dialect) 

Description

process_literal_param.__doc__

Receive a literal parameter value to be rendered inline within
        a statement.

        This method is used when the compiler renders a
        literal value without using binds, typically within DDL
        such as in the "server default" of a column or an expression
        within a CHECK constraint.

        The returned string will be rendered into the output string.
