OTL 4.0, Example 470 (MS SQL Server 2005, INSERT with OUTPUT clause)

This example demonstrates an MS SQL Server 2005 INSERT with OUTPUT clause and constant SQL statements.

Source Code

#include <iostream>
using namespace std;

#include <stdio.h>
#define OTL_ODBC_MSSQL_2008 // Compile OTL 4/ODBC, MS SQL 2008
//#define OTL_ODBC // Compile OTL 4/ODBC. Uncomment this when used with MS SQL 7.0/ 2000
#include <otlv4.h> // include the OTL 4.0 header file

otl_connect db; // connect object

void insert()
// insert rows into table
{
otl_stream o(1, // buffer size
"insert into test_tab (f2) "
"OUTPUT INSERTED.f1, INSERTED.f2 "
"
values(:f2<char[31],in>)",
// SQL statement
db, // connect object
otl_implicit_select // the statement returns an implicit result set
);
o.set_commit(0); // set stream auto-commit to OFF
char f2_in[32];
int f1;
char f2[32];

for(int i=1;i<=10;++i){
sprintf(f2_in,"Name%d",i);
o<<f2_in; // write input variable :f2
while(!o.eof()){ // while not end-of-data
o>>f1>>f2; // fetch the columns from the OUTPUT clause
cout<<"f1="<<f1<<", f2="<<f2<<endl;
}
}
db.commit(); // commit transaction

}

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

db.rlogon("scott/tiger@mssql2008"); // connect to ODBC

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 int not null identity, f2 varchar(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.sqlstate<<endl; // print out SQLSTATE message
cerr<<p.var_info<<endl; // print out the variable that caused the error
}

db.logoff(); // disconnect from Oracle

return 0;

}

Output

f1=1, f2=Name1
f1=2, f2=Name2
f1=3, f2=Name3
f1=4, f2=Name4
f1=5, f2=Name5
f1=6, f2=Name6
f1=7, f2=Name7
f1=8, f2=Name8
f1=9, f2=Name9
f1=10, f2=Name10
