The test says if you don't find correct answer in the given options, guess /choose the one which is more near to the correct answer and i was trying to do that. so it might help me if i had to take the test again.I went through few BOL topics (Transaction Log Truncation, Over Clause, Create Login, etc) and books to find these answers and thought they might be an option near to right one. Regarding sorting order, i went through the BOL over clause and tested on a table created my self and it worked. so i thought it might be true. Coming to full text indexes there is a book [i] "Mastering SQL Server 2008 By Michael Lee, Gentry Bieker"[/i] on page 626, chapter 21, second para of the new alter feature box, it is stated that [i]FTI's are backed up with every SQL Server Back up processes because they are included in the standard catalog [/i] so again with minimal knowledge about it, i assumed it to be true. your help is greatly appreciated and thanks for your tip [i]Don't confuse 'will usually work the way you want' with 'is guaranteed to work the way you want'.[/i], will keep it in mindThanks and RegardsDKTue, 19 Mar 2013 18:40:03 GMTbeginner_dkhttp://www.sqlservercentral.com/Forums/Topic1233541-391-1.aspx[quote][b]beginner_dk (3/18/2013)[/b][hr]A: I guess C is a possible answer as the transactions logs are automatically truncated with back up [/quote]No they're not.[quote]A: I am guessing B as the answer as "a link between tables" can also be a FK (FOREIGN KEY) and UC are used for FK's[/quote]They can be, but they're not required (either of the other 2 unique-guaranteeing structures is fine too). Still, a UQ does not in any way provide a link between tables, so no, B is wrong too.[quote]A: B as it is not mandatory to specify the partition by in over clauseIf PARTITION BY is not specified, the function treats all rows of the query result set as a single group. [/quote]B does not necessarily provide an ordered resultset. It provides row numbers ordered by the customer name, the resultset however is not necessarily ordered that way. The only one that has an ORDER BY clause (required for guaranteeing an ordered resultset) has a syntax error.Don't confuse 'will usually work the way you want' with 'is guaranteed to work the way you want'. No order by clause, no guarantee of order.For B to be correct, it needs ORDER BY CustomerName added at the end.[quote]A: D as coming from SQL SERVER 2008 Full text indexes are stored in databases unlike the previous versions where they are stored on disks structured outside the database[/quote]Outside the DB doesn't mean they're not backed up with the DB.

Transaction logs are truncated when you use SQL Profiler.B. Transaction logs are truncated when you use the following syntax: truncate table AC. Transaction logs are truncated when you backup your database.D. You can not backup transaction log.A: I guess C is a possible answer as the transactions logs are automatically truncated with back up Q: Which of the following statements about unique Constraints are TRUE?A. You can have only one unique constraint applied to a table.B. Unique constraints can be used to establish a link between two tables.C. You can only have one column assigned to a unique constraint.D.
