SQLite C Interface
Name Of A Host Parameter
const char *sqlite3_bind_parameter_name(sqlite3_stmt*, int);
This routine returns a pointer to the name of the n-th SQL parameter in a prepared statement. SQL parameters of the form ":AAA" or "@AAA" or "$AAA" have a name which is the string ":AAA" or "@AAA" or "$VVV". In other words, the initial ":" or "$" or "@" is included as part of the name. Parameters of the form "?" or "?NNN" have no name.
The first host parameter has an index of 1, not 0.
If the value n is out of range or if the n-th parameter is nameless, then NULL is returned. The returned string is always in the UTF-8 encoding even if the named parameter was originally specified as UTF-16 in sqlite3_prepare16() or sqlite3_prepare16_v2().

Invariants:
| F13621 | The sqlite3_bind_parameter_name(S,N) interface returns a UTF-8 rendering of the name of the SQL parameter in prepared statement S having index N, or NULL if there is no SQL parameter with index N or if the parameter with index N is an anonymous parameter "?" or a numbered parameter "?NNN". |
