VS IDE bug?


It seems the VS2005 IDE is still not quite stable...and not quite responsive too.

Row Number Transformation

Here is a Row Number Transformation component of SSIS

It's great, just fit my needs.
I suppose SSIS should provide this component...

Performance of SSIS Package

I think I need to study Database Tuning later... when I have time.

Recently I'm doing a Data Conversion project.
There are around 1.x million history records storing in 70+ VFP tables (1 table for each month).
I've made a looping package (it's new, great job M$!) to import such tables.
But the performance of the package is just bullshit.

Well, I guess the bottleneck is on VFP side (maybe VFP OleDB Provider, or File I/O of such VFP files (.dbf, .fpt ...).

SSIS IDE bug...?

Recently I am studying SSIS for my project.
I was stuck at some points while importing data from a VFP table.

The Execute Package Utility kept saying that there is a Truncation Error.
After spending for the whole afternoon, I got it...

It is because the IDE (VS2005) didn't always refresh the length of my source columns.

SSIS Home: SQL Server Integration Service

well, I will patch my VS2005 up to SP1...soon

DB Designer 4 - a Powerful Database Tool

Recently I am studying a "legacy" system and founding some tools to grab its database schema.
Well, I found, on my friend's blog last year...
Ken Choy Professional Edition: DB Designer 4

It is just great to have such tool.
It supports both forward and reverse engineering.

Thanks to the Open-Source community again!

Indexed View in SQL2K

It seems the usage of Indexed View is limited...to data warehouse only?
Mostly I am dealing with OLTP...

I wanna use index to boost my system, but it seems indexed view will slow down the performance.

System Table in SQL2K

It's interesting to have an "system" table declaring itself as a user table in the ANSI INFORMATION_SCHEMA views.

This message pointed out the findings while checking the system table "dtproperties"
