Unless you share the exact error with details, it would be difficult for anyone to even guess out.

Maybe, probably.... if you would actually describe a particular problem.

This is a SSMS setting. Sorry I am currently running something that is tying my system up so I cannot find it under Tools\Options

Do it using SQL Script (like alter etc...) instead of using SSMS

Suppose I have two tables (Emp and EmpCopy) in sql server database with following data:
Case 1: Data in Emp and EmpCopy table present like below:
Table: Emp
Id Name
----------------------
1 Emp_Name
2 Emp_Age
3 Emp_City
Table: EmpCopy
Id Name
--------------------
1 Emp_Name
2 Emp_Age
Case 2: Data in Emp and EmpCopy table present like below:
Table: Emp
Id Name
--------------------
1 Emp_Name
2 Emp_Age
Table: EmpCopy
Id Name
---------------------
1 Emp_Name
2 Emp_Age
3 Emp_City
Now according to cases given above I want retrieve records from both the tables, just like given below
Case 1:
Id Emp_Column EmpCopy_Column
1 Emp_Name Emp_Name
2 Emp_Age Emp_Age
3 Emp_City NULL
Case 2:
Id Emp_Column EmpCopy_Column
1 Emp_Name Emp_Name
2 Emp_Age Emp_Age
3 NULL Emp_City
Please reply ASAP.
Thanks in advance.

Suppose you had a script that created those tables, and inserted some data in it; wouldn't that cost about just as much time as writing all those fields like that?
The advantage of a script would be that it's clearly to read, easy to see what is going on, easily validated using copy/paste, and you'd probably get more (usefull) answers - simply because more people tend to paste a piece of Sql and try it, than to read a long story.

To prove that point, I'll be fetching some coffee. I suggest you post your code in PRE tags, including one or two queries that you already tried. They needn't be good, we're not going to whine about it; it's just a good idea to have "proof" you tried something.

Hi,
i have a SQL database select Query which brings 60 columns from 10 tables via join. i need to fetch 300000(3 Lacs) rows from database. It takes 18-19 seconds to fetch 300000 rows. I want to decrease this execution time to 10-12 secs.
I used "DATABASE ENGINE TUNING ADVISER of SQL SERVER 2008 R2, it suggested me 2 create some Indexes and statistics. I have created all this, but could not improved the performance of my query.
can anybody suggest me right solution ???

Count your blessings. I'd be ecstatic if some of the queries I'm working on currently took only twenty seconds.
One of the techniques I found that improved some of the worst (similar to yours) from several hours to about twenty minutes is the use of Common Table Expressions.
Instead of
SELECT ...
FROM A
INNER JOIN B...
INNER JOIN C...
INNER JOIN D...
You can do
WITH a AS
(
SELECT ...
FROM A
INNER JOIN B ...
)
, b AS
(
SELECT ...
FROM a
INNER JOIN C ...
)
SELECT ...
FROM b
INNER JOIN D ...

I agree. 18-19 seconds on a query that looks like its working with a good number of tables, and joins which is returning 300k rows does seem to horrible. Good luck to him at shaving down anymore time on it.

I agree with the performance observed. A query which returns 300K rows is typically not a online transaction where a user is waiting for the results to display, so what does it matter if you shave a few seconds off the execution time? (rhetorical question here)
Also noted is that there is no "where clause", so each time this query is run it will take longer and longer. Right? More and more data will be created each day...
If this is an online transaction, then maybe a strategy where summary tables are populated as transactions are being generated might be something to investigate.

I would strip your query down to the INNER JOINs and execute into a temp table. Optimize this if necessary. Then I would apply the LEFT JOIN lookups to the temp table.
I have found that complex queries can sometimes be sped up by a huge factor when broken up logically. In this case, you have the engine joining and executing numerous correlated subqueries (in the form of LEFT JOINS) at the same time.

In addition to Michael Potters suggestion, identify the inner join or where clause that reduces the quantity by the most records, this is the same as MPs suggestion except more focused. Shove that into either a temp table or table var. A temp table may have indexes applied if required.

I am using full text search to search through PDF documents using the Adobe iFilter. Everything works fine. Now, is it possible that I get a sentence which contains my searched keyword? For example:
Keyword:
'fox'
Query result:
'The quick brown fox jumps over the lazy dog.'
'Fox is a small red animal.'

Ehr.. yes, especially since you already mentioned that it works. Did you give it a try?
I got the feeling that I'm misunderstanding your question. English isn't my native tongue, and it helps if there's a bit explanation and some code to give an indication of what is expected. That said, kudo's for including the example with the expected output

I also think you've misunderstood my question When I said that everything works fine I meant that full text search over PDF documents works. I can retrieve a PDF document that contains a searched keyword. But, I need to retrieve a sentence or sentences from that or any other document that contain that keyword.

asimptota777 wrote: But, I need to retrieve a sentence or sentences from that or any other document that contain that keyword.
Then you will need IFilters for each type of document that's in your database. There's no way of reading "every" document, since each fileformat (and their versions) have different encodings and layouts.
You can download those for Office here[^] (2007/2010).
If you have a document in there in your own file-format (binary serialized data?) you'd probably have to provide your own IFilter implementation (guidelines on MSDN).
All existing and wide-used formats should have an implementation, since the same IFilter is in use for Desktop Search, SharePoint and the likes. And of course, CodeProject[^] has a lot of articles on the subject.

Thank you for an answer but I think you haven't read my question carefully. In my first post I said that I store PDF documents in the database (in the Filestream to be precise)and I use Adobe iFilter for full text search through PDF documents. That works fine. What I need is a way to get sentences from those PDF documents that contain a certain keyword. What T-SQL syntax can I use to extract sentences that contain a certain word?

USE AdventureWorks2012;
GO
DECLARE @SearchWord nvarchar(30)
SET @SearchWord = N'performance'
SELECT Description
FROM Production.ProductDescription
WHERE FREETEXT(Description, @SearchWord);
From MSDN[^]

Ok, I know about FREETEXT. But with this command you get THE WHOLE Description field. I need to get only the sentence that contains a keyword.
Query:
SELECT Description
FROM Production.ProductDescription
WHERE FREETEXT(Description, 'smooth');
Result:
1. Suitable for any type of riding, on or off-road. Fits any budget. Smooth-shifting with a comfortable ride.
2. Top-of-the-line competition mountain bike. Performance-enhancing options include the innovative HL Frame, super-smooth front suspension, and traction for all terrain.
3. Aerodynamic rims for smooth riding.
4. Excellent aerodynamic rims guarantee a smooth ride.

..it doesn't work that way; the document is returned, as it could contain the searched word more than once, in multiple locations. You can easily write some code to find the sentence with the word that was searched and extract it.

That's a list of requirements, not a programming question.

Dude, I know what full text search is and how it functions. I just don't know how to implement the functionality I've mentioned. I must admit that your signature really suits you...

Thank you - it was hard to earn that title 
You could repost the question with a link to this thread. State in the new post that this wasn't helpful, and someone might come up with something better.

I did not look at the requirements; technically, you want to retrieve documents based on a searchterm. You get a list of documents that contain that term. You can retrieve the document.
What's keeping you from doing a substring on that document and parse out the line? You can fetch the index where the word is in the document, then you work your way back to the first word with a capital letter, and forward to the first interpunction.

Hi all,
Every time my code tries to connect to my 2007 Access database, the message Unrecognized Database Format pops up. I've read that it is usually due to a corrupt database file or opening an old Access database file in newer version of Access Database. I can rule out opening an old file in newer Access because I've created and run the file in Access 2007. I can reasonably assume that since I can open the file, it is not corrupt. If those two aren't the causes what else could be causing it? The connection string in my web.config file takes the following form:
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\myFolder\myAccess2007file.accdb;Persist Security Info=False;
I don't know if that has anything to do with it, any suggestion will be greatly appreciated, thanks for your time.
