• SQL Server The 4000 character limit for expressions

  I am building rather large SQL statements using expressions and I am about to hit the 4000 character limit. First, what were the reasons for setting such a low limit With it in place you are forced to come up with other solutions, but perhaps that was the intention. Speaking of limits, what are the limits for storing a value in a string that is defined in a package configuration file What are the limits when creating a string within a script task and then use it to set a string variable in the package What are the limits when using a string value as an input parameter to an Execute SQL Task using OLE DB Do these differ depending on the co ...Show All

• Visual Basic When the grandkids can't inherit from their supposed parents.

  I'm doing something stupid or have screwed something up. Base is parent to DialogBase If you create new forms to inherit from Base they inherit fine. BUT if you try to inherit from DialogBase (by clicking on it) I get Base instead. So the kids get grandpa instead of pa. Suggestions please Regards, Al My feet are soooooo full of holes. I hope others are learning from my stupidity. Somehow or another the standard piece: Private components As System.ComponentModel.IContainer was missing from the designer.vb code.

• SQL Server Creating a Data-Flow Component

  I try to create a new Data-Flow Component. In Books-Online I found this link: ms-help://MS.SQLCC.v9/MS.SQLSVR.v9.de/dtsref9/html/9d96bcf5-eba8-44bd-b113-ed51ad0d0521.htm and the following pages.

• SQL Server Scaling Model for Sales Force Automation

  Read only transacted replication to about 60 clients. 100 or so transactions a day (8 hours), transaction (record) is probably about 8K/transaction. Reliable connection over 100base-T. Latency - 15 minutes would be great. This doable -- I couldn't find a timing/ sizing model any place. In a nutshell, it's doable. Aside from the usual hardware limitations (memory ,CPU, disk, etc., which you should be OK if you have multi-proc, remote distributor), you can hit OS limitations with regards to desktop heap. Without going into great detail, there's a chance you may get errors if you try starting all 60 distribution agent jobs at ...Show All
