CG Monroe commented on TORQUE-86:
---------------------------------
FYI - I'll take verify this patch today or tomorrow against my SQL servers.
If I have time, I may make it possible to turn this on / off via an options
tag. There may be situations that you DON'T want this protection turned off.
In general, we may want to optionally allow the exclusion of native mode
autogenerated fields in the Torque generated SQL. E.g, I want the records but
don't want to deal with id collisions on "import". But then again, there is
alway my XML import/export framework ( http://torque-addons.sf.net/ ) for full
control :).

> Key: TORQUE-86
> URL: https://issues.apache.org/jira/browse/TORQUE-86
> Project: Torque
> Issue Type: Bug
> Components: Generator
> Affects Versions: 3.2
> Reporter: Will Glass-Husain
> Priority: Minor
> Attachments: mssql_row.patch
>
>
> 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.
