# OTL 4.0, Example 456 (Simple Insert/Select with CHAR BYTE)

This example demonstrates simple INSERT and SELECT statements with the BINARY datatype as well as constant SQL statements.

## Source Code

    #include <iostream>
    using namespace std;

    #include <stdio.h>

    #define OTL_ODBC // Compile OTL 4.0/ODBC
    #include <otlv4.h> // include the OTL 4.0 header file

    otl_connect db; // connect object

    void insert()
    // insert rows into table
    {

     otl_long_string f2(700); // define long string variable
     otl_stream o(10, // buffer size
                  "insert into test_tab values(:f1<int>,:f2<raw[700]>)",
                     // SQL statement
                  db // connect object
                 );
     for(int i=1;i<=20;++i){
      for(int j=0;j<699;++j)
       f2[j]='*';
      f2[699]='?';
      f2.set_len(700);
      o<<i<<f2;
     }

    }

    void select()
    {
     otl_long_string f2(700); // define long string variable
     otl_stream i(10, // buffer size
                  "select * from test_tab where f1>=:f11<int> and f1<=:f12<int>*2",
                     // SELECT statement
                  db // connect object
                 );
       // create select stream

     float f1;

     i<<8<<8; // assigning :f11 = 8, :f12 = 8
       // SELECT automatically executes when all input variables are
       // assigned. First portion of output rows is fetched to the buffer

     while(!i.eof()){ // while not end-of-data
      i>>f1>>f2;
      cout<<"f1="<<f1<<", f2="<<f2[0]<<f2[f2.len()-1]<<", len="<<f2.len()<<endl;
     }

     i<<4<<4; // assigning :f11 = 4, :f12 = 4
       // SELECT automatically executes when all input variables are
       // assigned. First portion of output rows is fetched to the buffer

     while(!i.eof()){ // while not end-of-data
      i>>f1>>f2;
      cout<<"f1="<<f1<<", f2="<<f2[0]<<f2[f2.len()-1]<<", len="<<f2.len()<<endl;
     }

    }

    int main()
    {
     otl_connect::otl_initialize(); // initialize the database API environment
     try{

      db.rlogon("scott/tiger@sapdbsql"); // connect to the 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 CHAR(700) BYTE)"
        );  // create table

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

     }

     catch(otl_exception& p){ // intercept OTL exceptions
      cerr<<p.msg<<endl; // print out error message
      cerr<<p.sqlstate<<endl; // print out SQLSTATE
      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 the database

     return 0;

    }

## Output

    f1=8, f2=*?, len=700
    f1=9, f2=*?, len=700
    f1=10, f2=*?, len=700
    f1=11, f2=*?, len=700
    f1=12, f2=*?, len=700
    f1=13, f2=*?, len=700
    f1=14, f2=*?, len=700
    f1=15, f2=*?, len=700
    f1=16, f2=*?, len=700
    f1=4, f2=*?, len=700
    f1=5, f2=*?, len=700
    f1=6, f2=*?, len=700
    f1=7, f2=*?, len=700
    f1=8, f2=*?, len=700
