what is the different between primarykey and surrogated key.. why we are going for surrogatekey.....

Answer / g.v

Primary key as all of u know this is a unique key,surrogate
key is a non -intelligent key which is used to replace a
composite key


we are going for surrogate key bcz suppose a person is
living in one city and then moved to other and the person
id is a primarykey.we need to update the location then we
need to add the updated record but the primary key wont
accept to add the record again for this purpose we will go
for surrogate key

Hi Techies, I got an issue so need your advice here. I have created a report in Report Studio and it's having 2 columns which are having long text as a value (BLOB data type). Report is displaying entire text items in HTML format, but when I'm exporting it into EXCEL it's give me ##########. How to correct (wrap) it in Excel? so when end users they are directly running that report in Excel so instead of seeing ######### for long text items they should see the entire text items in those columns. Please advice!
