• Visual C# ?? Why No readonly Local Variables ??

  Hi all, I've looked at what the C# spec has to say and indeed it indicates the readonly keyword can only be applied to fields (not to local variables). I can see a use for doing this, however. I was wondering if anyone knows the rationale for not allowing readonly to be applied to local variables. It seems like it could be useful. Thanks. While readonly is very similar to const in appearance, w ...Show All

Groups and subgroups isn't an option. So is it possible with RDL and Reporting Service ...Show All

• SQL Server Impact of "Rows per batch" on OLE DB Destination?

  OLE DB Destination has a "Rows per batch" parameter. Are there best practices/guidelines around what it should be set to (for better performance etc) For example, if each row is of size 100 bytes, how does performance change when I set a batchsize of 0, 100, 1000, 10,000 etc I guess the default value for this parameter is zero. Does that mean, internally it is implemented as: For each row: begin transaction insert row commit tran ...Show All
