I'm updating a table in sql server from a front end written in C++. This some thing like this:

                  "UPDATE %s set "
                  "date_rec = '%s',"
                  "tpc = '%s',"
                  "cpc = '%s',"
                  "acquisition_strategy_code = '%s',"
                  "title = %d, "
                  "first_name = '%s',"
                  "middle_initials = '%s'"
                                                   " WHERE Id = %ld ",
When I execute this statement I get's the following error:  Syntax error converting the varchar value 'NULL' to a column of data type int.
Say for the title I got null passed in but in the table that is defined as integer so database throwing the above error. This is only a part of the sql string but I got really hughe sql string so I want to  convert all those values with 'NULL' to NULL then the database will accept this as a NULL keyword rather than as NULL string.
Can smoe one advice me please.
