TableUpdate Function

[Christian Soutou]

Hi
How use bind for a update function ?

// command line

CREATE TABLE bd_json.tab_vol_json2
(id_vol INTEGER AUTO_INCREMENT PRIMARY KEY,
doc JSON,
modif DATETIME
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

// shell

db.tab_vol_json2.insert( "doc","modif" ).
values(
'{"num_vol":"AF6148","date_vol":"2016-09-09","desc_vol":null,"sieges":null}',
'2016-09-09 20:00:00')

mysql-js> db.tab_vol_json2.update().
... set("modif" ,":dvol").
... where("id_vol=1").
... bind("dvol", "2016-09-09 19:35:00")
...
LogicError: TableUpdate.bind: Unable to bind value for unexisting placeholder: dvol at (shell):4:9
in bind("dvol", "2016-09-09 19:35:00")
