TASK: At my work we want to categorize and summarize all our IIS web logs and make statistics from it and such. What I need to do is take the browser type from a certain column in the table. All the information is stored in 1 column, and I figure an instr function would be best to do this. I am new to SQL, so I was told to look up the cursor function. In summary, I want to take all the IIS data and match it up against a defined table and then have a sum function for each browser.

Here are some examples of what the column data looks like: (found in the [csMethod] column

Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1)
Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+.NET+CLR+2.0.50727)
Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.1;+.NET+CLR+2.0.50727;+.NET+CLR+3.0.04506.30;+InfoPath.2;+.NET+CLR+1.1.4322)
Mozilla/5.0+(Windows;+U;+Windows+NT+5.1;+en-US;+rv:1.8.0.8)+Gecko/20061025+Firefox/1.5.0.8

I made a define table which lists an ID (primary key) and instr to search for as well as the full browser name. (define.browser)

DEFINE.BROWSER

I am having problems getting a cursor to work. Are there any good tutorials out there, or can anyone be of assistance. Thank you in advance.

select b.browsername
from log l
join browser b
on l.data like '%' + b.instr# + '%'

==========================================
Cursors are useful if you don't know sql.
DTS can be used in a similar way.
