## 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 "?NNN" or ":AAA" or "@AAA" or "$AAA" have a name which is the string "?NNN" or ":AAA" or "@AAA" or "$AAA" respectively. In other words, the initial ":" or "$" or "@" or "?" is included as part of the name. Parameters of the form "?" without a following integer have no name and are also referred to as "anonymous parameters".

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 UTF-8 encoding even if the named parameter was originally specified as UTF-16 in sqlite3_prepare16() or sqlite3_prepare16_v2().
