INFORMIX SERVER / 5725A3900 / B70 - IDS 11.70

bson_update(<bson>, "{$set:<update_json_string>}") working in 
most simplistic cases only: 
 
 - <update_json_string> can only contain a single key 
 - that key needs to exist already in <bson> 
 - its existing value, if complex, must have exactly same 
structure as new one 
 
For instance you would have this bson:   {a : 1, b : 2} 
 
You can say {$set : {a : 10}}  or  {$set : {b : 20}} 
 
but  {$set : {a : 10, b : 20}} would run into 
 
 9659: The server does not support the specified UPDATE 
operation on JSON documents. 
 
Same for  {$set : {c : 30}}  where key 'c' had not existed 
before. 
 
You also could say  {$set : {b : { b1 : 11, b2 : 12}}}, so 
replace key b's value by a more complex one, 
but then only e.g.   {$set : {b : { b1 : 21, b2 : 22}}}  would 
work on this, 
and not e.g.           {$set : {b : { b1 : 21, b2 : 22, b3 : 
33}}} 
                       or  {$set : {b : 22}} 
 
These quite confusingly now would run into -201 SQL syntax error 
-  during execution of the command.
