named parameters can be looked up using the
sqlite3_bind_parameter_name() API if desired.
The third argument is the value to bind to the parameter.
In those
routines that have a fourth argument, its value is the number of bytes
in the parameter. This is the number of characters for UTF-8 strings
and the number of bytes for UTF-16 strings and blobs. The number
of bytes does not include the zero-terminator at the end of strings.
If the fourth parameter is negative, the length of the string is
computed using strlen().
The fifth argument to sqlite3_bind_blob(), sqlite3_bind_text(), and
sqlite3_bind_text16() is a destructor used to dispose of the BLOB or
text after SQLite has finished with it. If the fifth argument is the
special value SQLITE_STATIC, then the library assumes that the information
is in static, unmanaged space and does not need to be freed. If the
fifth argument has the value SQLITE_TRANSIENT, then SQLite makes its

The third argument is the value to bind to the parameter.
In those

If the fourth parameter is negative, the length of the string is
number of bytes up to the first zero terminator.
