timestamp's contents
- public bool rewrite_statement_for_null_parameters (Statement stmt, Set @params, owned Statement? out_stmt) throws Error
Modifies stmt to take into account any parameter which
might be null: if stmt contains the equivalent of "xxx = <parameter definition>" and if that parameter
is in params and its value is of type GDA_TYPE_NUL, then that part is replaced with "xxx IS NULL".

- public string rfc1738_encode (string string)
- public Statement select_alter_select_for_empty (Statement stmt) throws Error

- public Binary string_to_binary (string? str)
Performs the reverse of
to_string (note that for any "\xyz" succession of 4 characters where "xyz"
represents a valid octal value, the resulting read value will be modulo 256).
- public Blob string_to_blob (string str)
- public string text_to_alphanum (string text)
