   (PHP 3>= 3.0.6, PHP 4 )
   odbc_connect -- Connect to a datasource

Description

   resource odbc_connect ( string dsn, string user, string password [,
   int cursor_type])

   Returns an ODBC connection id or 0 (FALSE) on error.

   The connection id returned by this functions is needed by other ODBC
   functions. You can have multiple connections open at once. The
   optional fourth parameter sets the type of cursor to be used for this
   connection. This parameter is not normally needed, but can be useful
   for working around problems with some ODBC drivers.

   With some ODBC drivers, executing a complex stored procedure may fail
   with an error similar to: "Cannot open a cursor on a stored procedure
   that has anything other than a single select statement in it". Using
   SQL_CUR_USE_ODBC may avoid that error. Also, some drivers don't
   support the optional row_number parameter in odbc_fetch_row().
   SQL_CUR_USE_ODBC might help in that case, too.

   The following constants are defined for cursortype:

     * SQL_CUR_USE_IF_NEEDED
     * SQL_CUR_USE_ODBC
     * SQL_CUR_USE_DRIVER
     * SQL_CUR_DEFAULT

   For persistent connections see odbc_pconnect().
