On persistent connections, a failed T-SQL will allow odbc_error and odbc_errormsg to return the error, but a subsequent successful T-SQL will not clear the error. Is it a bug?
(PHP 4 >= 4.0.5, PHP 5, PHP 7, PHP 8)
odbc_error — Obtém o último código de erro
$connection_id = ?): stringRetorna um estado ODBC de seis dígitos, ou uma string vazia se não houveram erros.
connection_idThe connection identifier.
Se connection_id é especificado, o último estado desta
conexão é especificado, senão o último estado de qualquer conexão.
Esta função retorna um valor significante apenas se a ultima consulta odbc falhou
(ex. odbc_exec() retornou false).

Using IBM DB2 V7.1 and MS SQL Server 7 ODBC database connections.
Print the result of odbc_error() or odbc_errormsg() after each call to an odbc_ function that gives no error and, sooner or later, you'll get garbage instead of a blank string!
If you use an argument, make sure its the CONNECTION_ID and not the RESULT_ID.
Testing the result can return a null string or sometimes a garbage string.
# -- Example code --
$rs = odbc_exec($dbc, $sql);
#this is wrong but won't error out until
#you demo the page for a client!
if (odbc_error($rs)) die(...);
#these work
if (odbc_error()) die(...);
if (odbc_error($dbc)) die(...);
I have use this function, its very simple and cute.
with IBM DB2
<?php
// you must set the connection first
if (odbc_error())
{
echo odbc_errormsg($conn);
}
// if you want to show the perfect error message
// then format it using string functions.
?>
Have a good day!
