How to change the Select and Edit N Rows option Context Menu in SSMS

You will be suprise to see the different options in Context Menu when you use SSMS for SQL Server 2008

the new option will allow you to get 1000 Row in Select Command and 200 Rows in Edit Commnad, the purpose of change is for fast loading.

However you still can change this option in SSMS setting.

go to Tools--> Option


















by default 0 represent ALL,

if you want to load all record for Edit you can change Value for Edit Top <n> Rows command to 0

the same can be apply for the Select Command, then your Context Popup Menu of SSMS 2008 will look much similar as SSMS 2005 one.

How to improve the performance of Fuzzy Grouping Analysis.

usually i run the SSIS to perform the fuzzy grouping analysis on data, my PC resource will totally eaten up by this process. i will need to wait until the process is completed

after i did some research on Google. i found that there is one property will control the memory allocation for the package execution. if  i set MaxMemoryUsage to be zero. the package will automatically allocate memory during the execution. it will free some memory and avoid the frozen of my PC.





























There is another tips to greatly improve the fuzzy grouping analysis performance.

Initially i run the fuzzy grouping ETL against the AS400 Data Source directly.

the whole process spend almost half days to complete and use up most of the resource.

After i Created another ETL to extract the data from AS400 and import them into SQL Server.

then run the fuzzy grouping analysis. the process dramatically improve and complete it within an hour. that is a huge difference comparing with the originally process

Please Remember Do Not performan Data Analysis against data source directly
