OTL 4.0, Example 699 (Simple Insert/Select)

This example demonstrates a simple INSERT with /*+APPEND_VALUES*/ optimizer hint that works the same way as /*+APPEND*/ in INSERT as SELECT statements in the releases of Oracle prior to Oracle 11.2

Source Code

#include <iostream>
using namespace std;

#include <stdio.h>
#define OTL_ORA11G_R2 // Compile OTL 4.0/OCI11.2
#include <otlv4.h> // include the OTL 4.0 header file

otl_connect db; // connect object

void insert()
// insert rows into table
{
otl_stream o(1000, // buffer size
"insert /*+APPEND_VALUES*/ into test_tab values(:f1<int>,:f2<char[31]>)",
// SQL statement
db // connect object
);

// /*+APPEND_VALUES*/ enables OCI direct path data loading feature
// in OCI11.2 and higher

char tmp[32];

for(int i=1;i<=100;++i){
sprintf(tmp,"Name%d",i);
o<<i<<tmp;
}
}

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

}

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;

}
