sql - Oracle temp tablespace alter statement -

-

what wrong query? had here not resolve problem.

sql> create temporary tablespace temprm;

tablespace created.

sql> alter  tablespace  temprm add datafile   '+tempdata/rm/datafile/temprm_temp01.dbf'; alter  tablespace  temprm add datafile   '+tempdata/rm/datafile/temprm_temp01.dbf' * error @ line 1: ora-03217: invalid option alter of temporary tablespace

a temporary tablespace made of tempfiles, not datafiles, so:

alter  tablespace temprm add tempfile '+tempdata/rm/datafile/temprm_temp01.dbf' size 2g; ----------------------------- here -^

python - jinja2: TemplateSyntaxError: expected token ',', got 'string' -

i have struct struct control_data{ int column_number; qstring cell; }; i need send thread of qsharememory. read can't because qstring contains pointers inside. other ways? you have serialize struct byte array. can convert qstring const char* this: mystring.tostdstring().c_str(); but serializing qstring should work. the first step serialize struct qdatastream using qt, example here . then once struct can read , written can pass shared memory. a complete example of using qsharedmemory can found here . here relevant code: // first, test whether shared memory segment attached process. // if so, detach if (sharedmem.isattached()) { sharedmem.detach(); } ... qbuffer buffer; buffer.open( qbuffer::readwrite ); qdatastream out( &buffer ); out << youstruct; int size = buffer.size(); // size of int + size of qstring in bytes if ( !sharedmem.create( size ) ) { return; } // write shared memory sharedmem.lock(); char *to = (char*...
