    Description

      Non-query API function calls appear in the audit log as QUERY events with empty query text. I don't see how it can be helpful, but can easily flood the log; so we need to either make them meaningful, or to get rid of them.

      The example below produces 2 such records, with mysql_list_fields(con,(const char*) "user",NullS) and mysql_close(con).

      Test case:

      #include <my_global.h>
      #include <mysql.h>
       
       
      int main(int argc, char **argv)
      {  
        MYSQL *con = mysql_init(NULL);
       
        if (con == NULL) 
        {
            fprintf(stderr, "%s\n", mysql_error(con));
            exit(1);
        }
       
        if (mysql_real_connect(con, "127.0.0.1", "root", "", 
                "mysql", 0, NULL, 0) == NULL) 
        {
            fprintf(stderr, "%s\n", mysql_error(con));
            mysql_close(con);
            exit(1);
        }  
       
        mysql_list_fields(con,(const char*) "user",NullS);
        mysql_close(con);
       
        exit(0);
      }

      Audit log:
