--------------------------------------

Thanks for the patch, Will.
Can a Torque developer who has access to a mssql db please confirm that this works ?

> For Microsoft SQL Server, if a primary key is of type IDENTITY (autoincrement), then you will not be able to insert a record containing a primary key.  
> For example, the following line will give an error if field WEB_APP_ID is a primary key.
> INSERT INTO WEB_APP (WEB_APP_ID,WEB_APP_NAME,ROOT_PATH,BASE_URL,IS_PRO,ALLOW_NATIVE_VENSIM)
>     VALUES (1,'Broadcast','c:/www/sims','http://localhost/sims/',1,1);
> The global property IDENTITY_INSERT can prevent this error.  However, if your dataset has a mix of tables, some with autoincrement and some without then you will not be able to set this globally.
> The solution is to check to see if the primary key is has the auto_increment property, and to wrap the insert with an IDENTITY_INSERT setting if so.  Example:
> SET IDENTITY_INSERT WEB_APP ON;
> INSERT INTO WEB_APP (WEB_APP_ID,WEB_APP_NAME,ROOT_PATH,BASE_URL,IS_PRO,ALLOW_NATIVE_VENSIM)
>     VALUES (1,'Broadcast','c:/www/sims','http://localhost/sims/',1,1);
> SET IDENTITY_INSERT WEB_APP OFF;
> I've attached a patch to the templates which implements this.
