Formulas in calculated columns

hi hi.. recently start work on Sharepoint admin area also, so now want to share about the simple formulas in calculated columns. At the custom list you can add in one new column with calculated type, then can use simple formula to pull data from othe column and do some calculation .
Below is the simple formula for IF :
=IF(Column1<=Column2, "OK", "Not OK")
However using the function like that causes a syntax-error.
The correct syntax is
=IF(Column1<=Column2; "OK"; "Not OK")
Date and time, Financial, Information, Logical, Lookup and reference, Math and trigonometry, Statistical,Text and data

Problem description:
=================
The data in SpUsageWeb.aspx don’t match the data in the UsageDetails.aspx page.

Plan:
==================
The issue is fixed in the April’s Service Pack, which is going to be released. We are now testing the Service Pack and will update you once we finish the test.
If no exception, I will send you the Service Pack early next week. Then you can try and see if the issue can be fixed by the Service Pack.

Additional information:
==================
The _layouts/usagedetails.aspx page is still available in SharePoint 2007, although there is no link to it in the site settings page.
If the Site Usage Report works properly, the data in the usagedetails.aspx should match the data in the SpUsageWeb.aspx.

VLOOKUP for you to join table

Just now try to gather all the DB size from DB and SharePoint CA, to join the data from DB and sharepoint at excel i use the VLOOKUP :

From CA Content DB

Database Name	Database Status	Current Number of Sites	Site Level Warning	Maximum Number of Sites
Contend_DB1	Started	4	8	10

From SQL Query > use this command at SQL query exec sp_databases

DB name	Size	MB	GB
Contend_DB1	165860032	161972.69	158.1764526

Combine the data in one excel sheer : DB size GB with following VLOOKUP
 =VLOOKUP(A2(this is the data you want to match), [the rage of the SQL query data],4(which role want to return),FALSE)

Database Name	DB Size GB	Database Status	Current Number of Sites	Site Level Warning	Maximum Number of Sites
Contend_DB1	158.1764526	Started	4	8	10
