Description
string 
ifx_error ( [resource connection_id] )
     The Informix error codes (SQLSTATE & SQLCODE) formatted as
     follows :
    
     x [SQLSTATE = aa bbb SQLCODE=cccc]
    
     where x = space : no error
    
 
     E : error
    
 
     N : no more data
    
        
     W : warning
    
        
     ? : undefined
    
     If the "x" character is anything other than space, SQLSTATE and
     SQLCODE describe the error in more detail.
    
     See the Informix manual for the description of SQLSTATE and
     SQLCODE
    
     Returns in a string one character describing the general results
     of a statement and both SQLSTATE and SQLCODE associated with the
     most recent SQL statement executed. The format of the string is
     "(char) [SQLSTATE=(two digits) (three digits) SQLCODE=(one
     digit)]". The first character can be ' '
     (space) (success), 'W' (the statement caused
     some warning), 'E' (an error happened when
     executing the statement) or 'N' (the statement
     didn't return any data).
