ODBC ERROR WITHE SQLINTEGER

What does this error mean I have tried All possible means of changing it but it is not working.

cannot convert ‘SQLINTEGER*’ to ‘long int*’ for argument ‘6’ to ‘SQLRETURN SQLGetData(void*, SQLUSMALLINT, SQLSMALLINT, void*, long int, long int*)’emphasized text

Here is the code
#ifndef CPSC_408_DB_H
#define CPSC_408_DB_H

#include <sql.h>
#include <sqlext.h>
#include <iostream>
#include <string> using namespace std;


class Monster {   public:

  Monster(string dsn);   ~Monster();
     void execQuery();


  private:   //used for connection and status   
   SQLHENV env;  
   SQLHDBC dbc;   
   SQLHSTMT stmt;   
   SQLRETURN ret; /* ODBC API return st开发者_JS百科atus */   
   SQLCHAR outstr[1024];   SQLSMALLINT outstrlen;




};



#endif


//sql getdata method
/* retrieve column data as a string */
  ret = SQLGetData(stmt, i+1, SQL_C_CHAR,
                         buf, sizeof(buf), &indicator);

It would help if you'd post the actual call to SQLGetData that the compiler is griping about, along with all related declarations, but I'll take a stab at it.

The last parameter to SQLGetData is supposed to a pointer to a long int (sometimes referred to as an SDWORD in some versions of the ODBC docs), not a pointer to an SQLINTEGER. Check the type of the variable whose address you're passing and update it as necessary.

Share and enjoy.
