How To Add More Data to the Testing Table?

If you want to continue with other tutorial exercises in this FAQ collection, you need to add more data to the testing table. Follow the script below to add a new column and more rows:

ALTER TABLE fyi_links ADD tag VARCHAR(8)
GO

UPDATE fyi_links SET tag = 'DEV' WHERE id = 101
GO
UPDATE fyi_links SET tag = 'DBA' WHERE id = 102
GO
UPDATE fyi_links SET tag = 'SQA' WHERE id = 103
GO

INSERT INTO fyi_links VALUES (104, 
   'www.mysql.com', '', '0', '2006-01-01', 'DBA')
GO
INSERT INTO fyi_links VALUES (105,
   'www.oracle.com', '', '0', '2005-01-01', 'DBA')
GO
INSERT INTO fyi_links VALUES (106,
   'www.php.net', '', '0', '2004-01-01', 'DEV')
GO
INSERT INTO fyi_links VALUES (107, 
   'www.winrunner.com', '', '0', '2003-01-01', 'SQA')
GO

UPDATE fyi_links 
   SET counts = CAST(LOG(id)*1000000 AS INT) % 1000
GO

SELECT * FROM fyi_links
GO
id   url                notes  counts  created     tag
101  dev.fyicenter.com  NULL   120     2006-04-30  DEV
102  dba.fyicenter.com  NULL   972     2007-05-19  DBA
103  sqa.fyicenter.com  NULL   728     2007-05-19  SQA
104  www.mysql.com             390     2006-01-01  DBA
105  www.oracle.com            960     2005-01-01  DBA
