Selecting different parts of a DATETIME with MSSQL

Thanks to this website for the information:

http://www.databasejournal.com/features/mssql/article.php/1442021

-- The syntax for pulling a certain part of a DATETIME is:
--
-- CONVERT(date_type[(length)],expression[,style])
--
-- The available styles are as follows:
--
-- NULL  Jun 24 2001 9:48PM
-- 1     06/24/01
-- 101   06/24/2001
-- 2     01.06.24
-- 104   24.06.2001
-- 108   21:48:00
-- 112   20010624
-- 121   2001-06-24 21:48:00.000

-- Some example usage:
SELECT CONVERT(DATETIME,GETDATE(),112) as date
-- Will output in YYYYMMDD format
SELECT CONVERT(DATETIME,client.birthday,101) as birthday
-- Will output in MM/DD/YYYY format

Limit equivelent for MSSQL

Props to this site for the answer:

http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=850&lngWId=5
// MySQL limit clause
SELECT emp_id,lname,fname FROM employee LIMIT 20,10

// MSSQL equivelent
select * from (
 select top 10 emp_id,lname,fname from (
    select top 30 emp_id,lname,fname
    from employee
   order by lname asc
 ) as newtbl order by lname desc
) as newtbl2 order by lname asc

"The main thing to remember is to deal with all your ORDER BY clauses and also to use the inner TOP as the sum of what you are looking for. In this example - 30 since you start at 20 and want 10 rows (20+10=30)."

Scripting schema updates in MSSQL #1

This SQL statement will alter a table only if a column in the table to be altered does NOT contain a column named 'FavoriteColorId'.

From: http://haacked.com/

IF NOT EXISTS
(
    SELECT * FROM [information_schema].[columns]
    WHERE    table_name   = 'Customer'
    AND      table_schema = 'dbo'
    AND      column_name  = 'FavoriteColorId'
)
BEGIN
    ALTER TABLE [dbo].[Customer]
    ADD FavoriteColorId int

Retrieve MSSQL table information

Retrieve tons of information (length, data type, name, etc.) of columns for a table. Works in (T|MS)SQL (all I've tested it in).
