I use oracle with C++.When I use SELECT statement it is ok, but when use UPDATE or DELETE, it will report this,why?
part of the code is following
exec sql CONNECT :username IDENTIFIED BY :password;
sql_statement.len = strlen((char *) sql_statement.arr);

exec sql PREPARE S8 FROM :sql_statement;
exec sql execute S8;
exec sql commit work release;

Thanks a lot!
