So we migrated dev sql server to 2008.
Our UAT sql server is still 2005.
i had to regenerate my entity framework model for some other reasons, and upon deploying my work to UAT i noticed this error:
cannot find data type datetime2
I profiled the database, and noticed that Entity Framework generated the input parameter as datetime2!
N'@p__linq__0 datetime2(7)',@p__linq__0='9999-12-31 00:00:00'
this executes fine in dev, because datetime2 is a type there. but fails when deployed to environment with 2005.
Is this some sort of known type? Why is entity framework not using regular datetime, and how can i make it cross environment compatible?
perhaps this is not 2008 upgrade related.. but it wasn’t an issue before the upgrade and this code has not changed.
Take a look at this ‘bug’ on MS Connect – the workarounds seem to supply a fairly straightforward fix.
Also covered here.
