# OTL 4.0, Example 407 (#define OTL_EXENDED_EXCEPTION, ODBC / Sybase SQL Server)

This example demonstrates #define OTL_EXTENDED_EXCEPTION. See also problem 47, and the otl_exception's extended fields.

## Source Code

    #include <iostream>
    using namespace std;

    #include <stdio.h>

    #define OTL_ODBC_UNIX // Compile OTL 4.0/ODBC
    #define OTL_EXTENDED_EXCEPTION // Enable extended field in otl_exception
    #include <otlv4.h> // include the OTL 4.0 header file

    otl_connect db; // connect object

    void insert()
    // insert rows into table
    {
     otl_stream o(10, // buffer size
                  "insert into test_tab values(:f1<int>,:f2<char[31]>",
                     // SQL statement
                  db // connect object
                 );

     o<<100<<"Row 100";

    }

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

      db.rlogon("scott/tigger@sybsql"); // connect to MS SQL Server

      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

      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 info.
      cerr<<p.var_info<<endl; // print out the variable that caused the error
      if(p.arr_len>0){ // checking if the extended fields were populated
       for(int j=0;j<p.arr_len;++j){
        cout<<"MSG["<<j<<"]="<<p.msg_arr[j]<<endl; // message array
        cout<<"SQLSTATE["<<j<<"]="<<p.sqlstate_arr[j]<<endl; // sqlstate array
        cout<<"CODE["<<j<<"]="<<p.code_arr[j]<<endl; // code array
       }
      }
     }

     db.logoff(); // disconnect from MS SQL Server

     return 0;

    }

## Output

    [Sybase][ODBC Driver][Adaptive Server Enterprise]Incorrect syntax near '@a1'.
