Example 44 (Get Rows Processed Count in Oracle 8)

Source Code

#include <iostream>
using namespace std;

#include <stdio.h>

#define OTL_ORA8 // Compile OTL 4.0/OCI8
#include <otlv4.h> // include the OTL 4.0 header file

otl_connect db; // connect object

void insert()
// insert rows into table
{ 
 otl_stream o(200, // buffer size
              "insert into test_tab values(:f1<float>,:f2<char[31]>)", 
                 // SQL statement
              db // connect object
             );
 char tmp[32];

 for(int i=1;i<=123;++i){
  sprintf(tmp,"Name%d",i);
  o<<(float)i<<tmp;
 }
 o.flush();

 cout<<"Rows inserted: "<<o.get_rpc()<<endl;

}

void delete_rows()
{ 
  long rpc=otl_cursor::direct_exec(db,"delete from test_tab where f1>=95");
  
  cout<<"Rows deleted: "<<rpc<<endl;
}

int main()
{
 otl_connect::otl_initialize(); // initialize OCI environment
 try{

  db.rlogon("scott/tiger"); // connect to Oracle

  otl_cursor::direct_exec
   (
    db,
    "drop table test_tab",
    otl_exception::disabled // disable OTL exceptions
   ); // drop table

  otl_cursor::direct_exec
   (
    db,
    "create table test_tab(f1 number, f2 varchar2(30))"
    );  // create table

  insert(); // insert records into table
  delete_rows(); // select records from table

 }

 catch(otl_exception& p){ // intercept OTL exceptions
  cerr<<p.msg<<endl; // print out error message
  cerr<<p.stm_text<<endl; // print out SQL that caused the error
  cerr<<p.var_info<<endl; // print out the variable that caused the error
 }

 db.logoff(); // disconnect from Oracle

 return 0;

}

Output

Rows inserted: 123
Rows deleted: 29
