oracle - Header formatting while spooling a csv file in sqlplus -


i required spool csv table in oracle, using sqlplus. following format required:

"host_site_tx_id","site_id","sitetx_tx_id","sitetx_help_id" "664436565","16","2195301","0" "664700792","52","1099970","0"

following relevant piece of shell script wrote:

sqlplus -s $sql_user/$sql_password@$sid << eof >> /dev/null     set feedback off     set term off     set linesize 1500     set pagesize 11000   --set colsep ,   --set colsep '","'     set trimspool on     set underline off     set heading on   --set headsep $     set newpage none       spool "$folder$filename$ext"     select '"'||pcl_carrier_name||'","'||sitetx_equip_id||'","'||sitetx_site_stat||'","'||sitetx_create_date||'","'||advtx_veh_wt||'"'     cvo_admin.missing_host_site_tx_ids;     spool off

(i have used commented statements in, signify things tried couldn't work)

the output receive is:

'"'||pcl_carrier_name||'","'||sitetx_equip_id||'","'||sitetx_site_stat||'","'||sitetx_create_date||'","'||advtx_veh_wt||'"' "transport inc","113","00000000","25-jan-13 10.17.51 am","" "transport inc","1905","00000000","25-jan-13 05.06.44 pm","0"

which shows header messed - literally printing whole string should have been interpreted sql statement, case data displayed.

options considering:

1) using colsep

set colsep '","' spool select * table spool off

this introduces other problems data having leading , trailing spaces, first , last values in files not enclosed quotes

    host_site_tx_id","   site_id"     "             12345","      16"     "             12345","      21

i concluded method gives me more heartburn 1 described earlier.

2) getting file , use regex modify header.

3) leaving header altogether , manually adding header string @ beginning of file, using script

option 2 more doable, still interested in asking, if there might better way format header somehow, comes in regular csv, (comma delimited, double quote bounded) format.

i looking less hard coding possible - table exporting has around 40 columns , running script around 4 million records - breaking them in batch of around 10k each. appreciate suggestions, totally different approach - programmer in learning.

one easy way have csv 1 header do

set embedded on set pagesize 0 set colsep '|' set echo off set feedback off set linesize 1000 set trimspool on set headsep off

the embedded hidden option important have 1 header

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...

c++ - End of file on pipe magic during open -

i have c++ application in starting process(wireshark) following. if (fp == null){ fp = popen(processpath, "r"); //processpath process want start if (!fp){ throw std::invalid_argument("cannot start process"); } fprintf(fp, d_msg);//d_msg input want provide process } else if(fp != null){ fprintf(fp, d_msg); } the problem when execute c++ application, start wireshark error end of file on pipe magic during open what should avoid that? also tried using mkfifo create named pipe , execute it. used this: if (fp == null){ system("mkfifo /tmp/mine.pcap"); fp = popen("wireshark -k -i /tmp/mine.pcap", "r"); if (!fp){ dout << "cannot start wireshark"<<std::endl; throw std::invalid_argument("cannot start wireshark"); } input = fopen("/tmp/mine.pcap", "wb"); fprintf(input , d_msg); fclose(input)...
