sql - How to get formatted XML out of Oracle -


i'm inexperience oracle , having trouble exporting data xml. i've managed query working, format of xml seems fixed , won't work me. here's query:

select value(em).getclobval() "output"     table(xmlsequence(cursor       (              select * usermain        ) )) em

what is:

  <row><status>active</status><name>joe smith<name><phone>234-2345</phone>...</row>   <row><status>inactive</status><name>sally smith<name><phone>234-4444</phone>...</row>   etc.

but want this, xml tags "rows" around outside of output, shown here:

  <rows>       <record><status>active</status><name>joe smith<name><phone>234-2345</phone>...</record>       <record><status>inactive</status><name>sally smith<name><phone>234-4444</phone>...</record>       etc.   </rows>

so need query change , put outer tags around output?

there trick i've found years ago. if use xmltype , apply xsl template xmltype using oracle transform function, there unexpected behaviour: xml becomes formatted. unexpected , point of view funny.

this procedure trick:

procedure beautify(xmlout in out nocopy clob)       xml    xmltype := new xmltype(xmlout);     xsl    xmltype := new xmltype('<?xml version="1.0" encoding="iso-8859-1"?><document></document>');     tmp    xmltype; begin   tmp := xml.transform(xsl,null);   xmlout := xml.getclobval;    if tmp null null; end if; end;

of course, should pass function valid xmltype, e.g. in case should kind of

<?xml version="1.0" encoding="iso-8859-1"?> <document>   <row><status>active</status><name>joe smith<name><phone>234-2345</phone>...</row>   <row><status>inactive</status><name>sally smith<name><phone>234-4444</phone>...</row> </document>

please, note encoding="iso-8859-1" used german language, should change use encoding purposes.

if want use in query can create function instead of procedure. can add additional rows before formatting , remove after formatting.

this works in oracle 11.2

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)...
