class SqlRaw : public String, private AssignValueTypeNo<SqlRaw, SQLRAW_V>
This type represents a string with binary data. It is required because otherwise Sql interface would be unable to tell which sql statement parameters should be treated as regular texts and which parameters are raw binary data (to be stored into raw binary data columns).
Note that only input parameters - values in Insert/Update statements - can be SqlRaw. When fetching data from database, normal String values are returned for binary columns.
