How to fix this.

Thanks

Anyway I have one question regarding execute and executeAsync. Since this behavior is set when the connection is opened - do you think it would be a good idea to keep track of the connection type and throw an exception if execute is called when openAsync was specified, or vice versa? I don’t see in the code where this would be handled.

Thanks for providing this little API, it’s extremely handy.

In regards to the SQLStatementHelper I have not had any injection issues because of this therefore I haven’t changed the implementation in this release. With that being said I do plan to make some changes to this implementation in a future update.

In regards to the item class it is a non-issue in the executeAsync method as the SQLStatement object is being re-instantiated in every call. However it is not being re-instantiated in the execute method so I will add an update to this soon.

Typically for Web Services (WSDL, REST, XML over HTTP, etc) I define a separate Service on the the ServiceLocator as well as a separate Business Delegate for each service.

For AIR applications utilizing local databases there are two ways to implement this:

A.) Define one Service (for connecting / accessing the database) on the ServiceLocator and then separate Business Delegates for each table.
- or -
B.) Define a separate Service and Business Delegate for each table.

Personally I suggest having one Service for each database as it simplifies debugging the connections as there will only be one connection to manage per database. As far as organizing is concerned this is best achieved by having separate Business Delegates for each table, these delegates would then define all of the operations which can be performed on the respective table.

If conceptually it makes more sense to you to define a separate SQLService object for each Service you could always just sub class SQLService and then define an instance of the sub class for each specific service, thus utilizing the same connection and database while separating the SQLService by function.

Hope that helps,
Eric

I dived a little bit into the code and have some questions.

In SQLStatementHelper you are using StringUtil.substitute to create the sql statement. I don’t think this safe related to SQL injection. Shouldn’t you use ? or named parameters instead?

I also noticed that in the execute method the itemClass is only set when it provided (not null). In case statements are reused (and this is the case for the sych executed method!!) then it could happen that a previously set itemClass is used in the query. I don’t know if this could cause any problem, but why not set always the itemClass?

One question.
In your AIRCairngormSyncExample you have specified an userService.
The example seems to indicatie that a SQL service maps to a database file.

When you have multiple services (like an productService, orderService, customerService etc.) do they have to map to multiple database files. I currently have 1 database file containing all my tables. But I want multiple service to organise everything.

How should I do this? Is it just opening referencing to the same database filename? That would also mean multiple opened connections? Will this have some drawbacks?
How do you do this in your projects?
