Looks like you forgot a call to format before the opening
parenthesis.
should be:
string sqlinsert = format(`INSERT INTO usersshapes (userlogin,
uploading_date, geometry_type, data) VALUES ('%s', '%s', '%s',
'%s') `, login, uploading_date, geometry_type, data);
because what ends up happening is :
string sqlinsert = data;
which is almost certainly not what you want.
