I'm glad to hear I'm not the only one with the chain of MSSQLServer around my neck! I won't be WOWODC west, maybe at east.
thanks again and I'm downloading Chuck's MSSQLServerPlugIn right now. -fw David Avendasora <webobje...@avendasora.com> 05/28/2009 05:21 AM To Fred Wells <fred.we...@marketforward.com> cc Development WebObjects <webobjects-dev@lists.apple.com> Subject Re: lock operation locked more than one row issue! -- SOLVED Hi Fred Glad to hear that you have everything working!

Also I'm not sure where the prototypes are from but the ones that just show up in Entity Modeler have some issues specifically with the number prototypes. Anyway after clearing those out and getting the data types to show up correctly everything is on. You must have the ERPrototypes framework added to your classpath. This is what provides all the various prototypes. If you look in your DB config, there's a place you can select the set of Prototypes you want to use. The problem is that there isn't one that is specifically for MSSQLServer. I've created my own prototypes. It is simple to do and will make your life much easier in the future - and will keep Chuck from calling you stupid at WOWODC. :-) 1) Take ERPrototypes out of your project's build path. 2) Create an entity in your Model called "EOJDBCPrototypes" then add an attribute for each prototype you want. I'd even use the same names as the WOnder ones you were using, just change the external type to match SQLServer's. For example, I use NVARCHAR instead of VARCHAR beause it is MSSQLServer's data type that can store unicode strings without conversion. At some point we should add MSSQLServer prototypes to ERPrototypes, I'll look into it after WOWODC. Any chance you are going to be there? thanks everybody. Those of us afflicted with MSSQLServer need to stick together. Thankfully Chuck is so afflicted (ha ha Chuck!). I find using MSSQLServer with WebObjects to be similar to Vertical Inheritance in that it should work in theory and usually does at first, but then the more you dig into it you start to find things that just don't work quite as you'd expect and since most people on the list don't use it, there are obscure bugs lurking waiting to bite you. If you are not using Chuck's MSSQLServerPlugIn, You will want to, otherwise you are going to end up with intermittent FK-constraint errors. Even if you haven't yet, you will. Use it.

What ERPrototypes are you using? There is no set of MSSQLServer Prototypes, and the JDBC define java.lang.Integer attributes (id, intNumber, intBoolean, etc) as having an external type of INTEGER, which is not what SQL Server calls an Integer data type. It uses 'int'. Maybe that's it?

Right now I'm just looking for any more ideas as to where look for a possible cause on this. The EOModel files seem to be fine I can't find anythign out of the ordinary I'm not sure where else to look or if there are any parameters that can be changed to alter how locking is handled. Are you saying you looked at the EOModel's plist files? If not, can you paste the contents of that entity's .plist file here? You said you had been using Vertical Inheritance at one point. I have seen stuff get left over in the .plist even when the Entity Modeler UI doesn't show it.
