Your problem is that the sqlite3_value_text() function is defined to return a const unsigned char pointer, and you are assigning that value to a non-const signed char pointer. From the documentation at http://www.sqlite.org/c3ref/value_blob.html const unsigned char *sqlite3_value_text(sqlite3_value*); Your assignment above discards the const qualifier. It also ignores the fact that the types differ in their signedness. You should change your str variable to be a const char pointer, and then explicitly cast away the unsigned qualifier. const char *str; str = (const char*)sqlite3_value_text(...); HTH Dennis Cote _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
