@jurgen The problem is using the ‘?’ index parameter next to the ‘%’ character – that’s why the error keeps getting thrown.

The solution is to concatenate the parameter with the character like this, where ‘||’ is the concatenation operator in SQLite:

sql = “SELECT anyvalue FROM anytable WHERE anyvalueLIKE ? || ‘%’”

Interesting stuff! Just got into Mate today after using UM Cairngorm for the past 6 months. I too plan to have a go at hacking your code to put in the transaction management, which is really easy. I don’t think Mate’ll be appropriate for the sorts of things I’m doing with SQLite, but an interesting challenge nonetheless.

I know it’s possible, but I’m yet to figger out why; It doesn’t seem like leaving the connection open from multiple operations is actually any faster than closing it every time. I was testing it on a coupla hundred inserts/deletes rather than selects (before I had transactions working), so maybe there’s benefit purely on selects…?

@jurgen: Have you tried something like this?
sql = "SELECT anyvalue FROM anytable WHERE anyvalue LIKE 'a%'"
Note the ‘ ‘ for the wildcard definition within the SQL statement.

Thank you for this great example..

Regarding the SQLManager .. how would I define the sql if I wanted to use WHERE .. LIKE instead of = ?
Tried adding % to the string but I always get errors.

Thanks in advance!

When I try to start the application it quits without even showing the main screen… I’m using AIR 1.5. Any idea?

@Andrew: At the moment I don’t plan any improvements on this extensions.

Feel free to add your “hack” to the original extension on Google Code. It’s open source Thanks!

Hi Jens

Have you thought to update the extension to include an argument for the encryptionKey parameter for the connections open() method for encrypted databases for AIR 1.5?

I’m hacking the original source for now for an application I’m using your extension on.

Thanks, Andrew

@Jon: At the moment I don’t plan to add an asynchronous support.

Have you tried to checkout the source using SVN? It should be available using the following command: svn checkout http://mate-examples.googlecode.com/svn/trunk/ mate-examples-read-only.

Or you can check the code using your Browser (without Google’s interface): http://mate-examples.googlecode.com/svn/trunk/examples/airsqlite/

Real question: Do you plan on adding support for Async connections?
