# OTL 4.0, Example 330 (Simple Insert/Stored Proc with Result Set)

This example demonstrates a simple INSERT and a stored proc that returns a result set.

## Source Code

    #include <iostream>
    using namespace std;

    #include <stdio.h>
    #include <string.h>
    #include <stdlib.h>

    #define OTL_ODBC // Compile OTL 4.0/ODBC
    // #define OTL_ODBC_UNIX // uncomment this line if UnixODBC is used
    #include <otlv4.h> // include the OTL 4.0 header file

    otl_connect db; // connect object

    void insert()
    // insert rows into table
    {
     otl_stream o(50, // buffer size
                  "insert into test_tab values(:f1<int>,:f2<char[31]>)",
                     // SQL statement
                  db // connect object
                 );
     char tmp[32];

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

    void select(const int af1)
    {
     otl_stream i(50, // buffer size
                  "{call prc1(:f1<int,in>)}",
                     // Stored Proc Call
                  db, // connect object
                  otl_implicit_select // implicit result set / select
                 );
       // create select stream

     int f1;
     char f2[31];

     i<<af1; // Writing a input value into the stream
     while(!i.eof()){ // while not end-of-data
      i>>f1;
      cout<<"f1="<<f1<<", f2=";
      i>>f2;
      if(i.is_null())
       cout<<"NULL";
      else
       cout<<f2;
      cout<<endl;
     }

    }

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

     db.rlogon("scott/tiger@sapdbsql"); // connect to database

      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, f2 varchar(30))"
        );  // create table

      otl_cursor::direct_exec
       (
        db,
        "DROP PROCEDURE prc1",
        otl_exception::disabled // disable OTL exceptions
       );

      otl_cursor::direct_exec
       (
        db,
        "CREATE DBPROC prc1 (IN f1 int) "
        "RETURNS CURSOR AS "
        "$CURSOR = 'CUR1'; "
        "DECLARE :$CURSOR CURSOR FOR "
        "SELECT * FROM scott.test_tab WHERE f1 >= :f1 and f1 <= :f1*2; "
       );

      insert(); // insert records into the table
      select(8); // select records from the 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 ODBC

     return 0;

    }

## Output

    f1=8, f2=Name8
    f1=9, f2=Name9
    f1=10, f2=Name changed
    f1=11, f2=NULL
    f1=12, f2=Name12
    f1=13, f2=Name13
    f1=14, f2=Name14
    f1=15, f2=Name15
    f1=16, f2=Name16
