odbc_errormsg — Get the last error message

### Description

odbc_errormsg(?Odbc\Connection `$odbc` = `null`): string

Returns a string containing the last ODBC error message, or an empty string if there has been no errors.

### Parameters

`odbc`

  The ODBC connection object, see odbc_connect() for details.

### Return Values

If `odbc` is specified, the last state of that connection is returned, else the last state of any connection is returned.

This function returns meaningful value only if last odbc query failed (i.e. odbc_exec() returned `false`).

### Changelog

Version | Description
--- | ---
8.4.0 | `odbc` expects an Odbc\Connection instance now; previously, a resource was expected.
8.0.0 | `odbc` is now nullable.
