15 Releases the binding of the connection to the database and user associ‐
16 ated by odbx_bind() to the supplied connection object. This is useful
17 for switching to a different database or binding to the database with
18 different credentials. It is also possible to set new connection relat‐
19 ed options before rebinding to the database server. If an open transac‐
20 tion exists while this function is executed in the firebird backend, it
21 will be committed to the database and closed. The behavior of the other
22 backends for open transactions may vary.
23
24 It's necessary to process all result sets returned by the database
25 server before using this function. Otherwise, it might return an error
26 depending on the native database client library and the backend module.
27 This function must be invoked before calling odbx_finish() to avoid
28 memory leaks and connections left open which may block necessary re‐
29 sources later on.
30
31 The handle parameter has to be the connection object created and re‐
32 turned by odbx_init(). It becomes invalid after it was supplied to
33 odbx_finish() and odbx_unbind() will return an error in this case.
34
36 odbx_unbind() returns ODBX_ERR_SUCCESS, or an error code whose value is
37 less than zero if one of the operations couldn't be completed success‐
38 fully. Possible error codes are listed in the error section and they
39 can be feed to odbx_error() and odbx_error_type() to get further de‐
40 tails.
