EXPLAIN Function

May 19, 2008

Is there some equivalent to MySQL's EXPLAIN function? (or some utility that does the same thing?)

Basically the function takes a query and will return a list of the tables in the query and the number of rows that would need to be checked. It's used to check how well the indexes are set. (If a table returns a very high number, that could be a bottleneck for the query).

Any help is appreciated. Thanks.

Can Someone Please Explain This To Me...

Jun 26, 2007

why do the following return the same datasets?
 select * from myTable where myData = ''
 select * from myTable where myData = '     '
in the first I'm specifically searching empty strings, in the second a sequence of five spaces. Yet both return any and all white character matches? Is this a "feature" of SQL...
P.S. I'm using T-SQL

Could Someone Please Explain The Following...

Dec 1, 2005

As previous threads have indicated I've been trying to figure out what's slowing down our 3rd party ETL tool.

My research has figured out the culprit, but now I need some advice on the best way to handle it.

Here's what's going on...
SPID 1 = dynamic sql passed from Crystal
SPID 2 = ETL tool
SPID 3 = report in stored proc

Until a few days ago we didn't even know SPID 1 existed. These are different guys, using old version of Crystal passing crappy queries.

Here's the scenario
SPID 1 is running (inefficient select)
SPID 2 is waiting
30 minutes pass and SPID 2 is still waiting PAGEIOLATCH_SH
SPID 3 fires off

Now SPID 2 is blocking SPID 3, but SPID 2 is still waiting for SPID 1

Finally when SPID 1 finishes, everything catches up. But it appears that there is a period of at least 45 minutes when all SPID's are just sleeping.

My questions:
1. If SPID 1 is just running an inefficient select query, why is it holding up SPID 2 (Which reads and inserts). SPID 1 should have a shared lock on table, this would prevent SPID 2 from insert/update?
2. Is there any steps I can take to give SPID 2 precendence? or is it first come first serve?

Thanks in advance

Can Some Explain This To Me?

Oct 25, 2007

Hello,I run the following query on a database (SQL 2005):delete from person where pers_companyid in (select pers_companyid fromcompany where comp_expiry is not null)I wanted to delete all people associated with a company which had anexpiry date. The mistake I made was that the column pers_companyiddoes not exist. It should have been comp_companyid.However, the query ran anyway and deleted all records from my persontable? If I run the subquery on its own then it doesn't run as thecolumn is missing.Shouldn't I have got an error running this query?Thanks,David

Please Explain Transaction For Me

Sep 29, 2007

 I found this on http://msdn2.microsoft.com/en-us/library/86773566.aspx which i am hoping may be able to resolve my problem but I am not sure I actually understand it. Where it shows // Start a local transaction. transaction = connection.BeginTransaction("SampleTransaction");
is the "SampleTransaction" nothing more then just a name of the transaction that is being created through this code or is it actually pointing to something?I believe that I understand the rest. Oh and in case you have a better way of doing what I am needing here is the SQL Query that is pulling info for me to display on a pageSELECT     p.product_ID, p.class_ID, p.category_ID, p.product_name, p.product_desc, p.product_image, p.product_dimension, p.product_o1, p.product_o2,                       p.product_o3, p.product_ac, p.product_ph, p.product_photo, pcl.class_name, pca.category_nameFROM         products AS p INNER JOIN                      productClass AS pcl ON p.class_ID = pcl.class_ID INNER JOIN                      productCategories AS pca ON p.category_ID = pca.category_IDBasically I am using the transaction to perform multiple updates seeing as how I will need to update multiple tables.  private static void ExecuteSqlTransaction(string connectionString){ using (SqlConnection connection = new SqlConnection(connectionString)) { connection.Open(); SqlCommand command = connection.CreateCommand(); SqlTransaction transaction; // Start a local transaction. transaction = connection.BeginTransaction("SampleTransaction"); // Must assign both transaction object and connection // to Command object for a pending local transaction command.Connection = connection; command.Transaction = transaction; try { command.CommandText = "Insert into Region (RegionID, RegionDescription) VALUES (100, 'Description')"; command.ExecuteNonQuery(); command.CommandText = "Insert into Region (RegionID, RegionDescription) VALUES (101, 'Description')"; command.ExecuteNonQuery(); // Attempt to commit the transaction. transaction.Commit(); Console.WriteLine("Both records are written to database."); } catch (Exception ex) { Console.WriteLine("Commit Exception Type: {0}", ex.GetType()); Console.WriteLine(" Message: {0}", ex.Message); // Attempt to roll back the transaction. try { transaction.Rollback(); } catch (Exception ex2) { // This catch block will handle any errors that may have occurred // on the server that would cause the rollback to fail, such as // a closed connection. Console.WriteLine("Rollback Exception Type: {0}", ex2.GetType()); Console.WriteLine(" Message: {0}", ex2.Message); } } }}

Please Explain This SQL Trigger

Sep 25, 2005

I am new to triggers.I am unsure why on the SELECT statement the ROLLBACK is enforced. I thought this would be only for when an attempt is made to insert the data. Also what is the pupose of IF @counter = 1 When does this counter change value? USE Northwind GO CREATE TRIGGER PriceCheck     ON [Order Details]     FOR INSERT     AS DECLARE @counter int     SET @counter= @@ROWCOUNT     DECLARE @unitprice money     DECLARE order_details_insert_cursor CURSOR FOR         SELECT Unitprice             FROM inserted     IF @counter = 1         BEGIN             IF(SELECT UnitPrice FROM inserted) > 300             -- If the price entered is greater than 300             BEGIN                 --print a warning                 PRINT 'Cannot enter price greater than 300'                 --Take back the command                 ROLLBACK TRANSACTION             END         END     ELSE         BEGIN             OPEN order_details_insert_cursor             FETCH NEXT FROM order_details_insert_cursor INTO @unitprice             WHILE @@FETCH_STATUS = 0                 BEGIN                     if @unitprice > 300                     -- If the price entered is greater than 300                     BEGIN                     --print a warning                         PRINT 'Cannot enter price greater than 300'                         --Take back the command                         ROLLBACK TRANSACTION                         RETURN                         --Exit trigger immediately                     END                     FETCH NEXT FROM order_details_insert_cursor INTO @unitprice                 END                                  CLOSE order_details_insert_cursor             END                          DEALLOCATE order_details_insert_cursor

Explain Xp_cmdshell

Feb 2, 2006

I've got some questions about xp_cmdshell and was hoping someone could explain some things to me.  I've written a trigger for a table that uses 'xp_cmdshell' to launch a VB.Net application.  The syntax is correct and it "seems" to work but in the way I intended.  When the app launches there is no GUI present but when I check the task list I see that the exe has been launched.  This intrigued me so I started playing with it in Query Analyzer.  When I run the commandexec master.dbo.xp_cmdshell 'C:WINDOWSsystem32otepad.exe'I seen a process for notepad show up on my processes list started by 'system' as opposed to myself and notepad still doesn't open up for me to see.  I also noticed that the query executes until I kill that particular process.  I'm guessing cause it's waiting on the tranaction to complete.  What I want to know though is why can't I see the program when I open like this?  Is it because 'system' is the user behind it or is there some extra parameter to throw in the xp_cmdshell?

Hi,

Could someone help me understand this script:

DECLARE @TempValue tinyint

SELECT @TempValue = 1
FROM dbo.TABLE_NAME (tablockx updlock holdlock)
WHERE 1 = 2

To my understanding, it would lock all the row in the table at once.

Could Anybody Explain To Me Why Sqldatadpater Does Not Allow Subqueries?

Aug 17, 2007

Dear experts,
Recently i got an error msg looks like this: you cannot use subqueries within a sqldatadpter except the subquery is introduced with EXISTS.
Well, actually i was using IN.
I know I can revise my query sting to use INNER JOIN or such stuff just to remove the nested queries. But i'm realllllly curious why it's not allowed??
Really appreciate it if some expert can tell me.
Thanks in advance

You Can't Explain This! ARRRRG! SQL Ghost!

Dec 23, 2007

Hello all,
Where do I start?  My son and I wrote a small ASP.net 2.0 website on XP IIS 5.  Works ok with the standard login controls.
I FTP'ed the files up to a Windows server2003.  I installed the SQL publishing wizard.  I created a .sql file of the data base.
I ran the file in SQL2005 manager to build the data base on SQL express running on the Windows 2003 server.  It installed,  no errors.  great!
The website would not run with Data base connection errors ,  like files or data base was read only,  duplicate database ,  can not run mydatabase.create.  something like that.
I created a new app pool and made sure network service was the account.  Gave network server permissions to the folders,  it started working great.
Now sit down.  I created a few accounts using the website  ok,  no errors, Great!   Then check the database to see if the passwords were encrypted.  The new accounts were not there. 
But the accounts went somewhere????   Must be two databases????  One hidden?
I detached the database I created with the .sql script file....  to see if I would get an error on the browser.  nope still worked. Hmmmm other hidden database still working.... I stopped database server
in the management tool,    It still worked....Ok, I'll get the house check for poltergiests.
I went to SERVICES.  The service was stopped(SQLEXPRESS)..  I changed auto start to manual.  Browsed back to the site again,  finally an error.
I restarted the service,  website worked again,  but the database,  the only user database,  is still detached.  Created more user accounts with no error....
Seached the hard drives for .MDF files.  Found the file I detached and also the ASPNETDB.MDF that I orginally FTP'ed to the server earlier in the APP_DATA folder of the website.  I renamed the  
MDF file to see if then I would get an error,  yep I did.    It then automatcly re-created the MDF file exactly the same size.  Two files in the directory now and now a new error in the browser
about a database mismatch.  Ok  that makes sense.   But it will not allow me to rename the new file so I can rename the original. 
Question is how does SQLEXPRESS run the ASPNETDB.MDF file in the web folder which is not attached to the database engine? 
Why use a SQL pub wizard if ASP.NET creates the database automaticly? Or just "Runs" it?    AM I HIGH?
Thanks in advance,  before I take drugs and sit in a dark closet.
-Wade

Can Anyone Explain To Me Why This Is Not A Good Idea

Jan 28, 2008

I have a complex select statement that is used in several stored procedures. I decided that instead of having x number of T-SQL scripts with the same exact select statement that I would to put this query into a view and then do a select * from View.  Recently an instructor told me that this was a bad idea and that anyone who uses a select * from anything should be fired.  When I asked for his reasoning his response was to say the least abnoxious.  I can understand why a Select * from Table might be a bad idea as the table definition can change, but the chances of a view changing seems much less likely.
Is a view a good idea in this case?  Is the Select * from View really a bad idea?
 Thanks

Can Someone Explain The Precision Of An Integer In A Sql Db Pls

Nov 3, 2003

Hi I am in the process of creating a new db in sql. In my users table I wish to set the UserIds as Integer datatype. It defualts on precision 4. Does this mean that when the column auto increments as its my primary key with a seed of one, my highest number allowed in the table would be row 9999. ???

Also if you where to store a phone number in your db, what column type would you give it. I have used varChar but its all numbers i want to store. Would this suffice.

Thanks

Can Someone Explain This Strange Value Of @@ROWCOUNT?

May 31, 2006

I have noticed the following strange situation, but cannot find any explanation.  The @rows variable is 1 , even though the @@ROWCOUNT value just after the select statement is 0. (I have checked this by stepping through the SP).
update Products set ParentId = @parent where ParentId = @lastParentIdset @err = @@ERRORset @rows = @@ROWCOUNT
However, if I set @rows before @err then the @rows is correctly set to 0. (as in script below).
update Products set ParentId = @parent where ParentId = @lastParentIdset @rows = @@ROWCOUNTset @err = @@ERROR

I Need A CONNECTION GURU To Explain What Is Going On.

May 26, 2006

I have a application that uses a connection that is always active until the application is closed, and many other connections that are opened and closed as different data is requested. I DO close and dispose these connections, datasets, and data readers after requesting data to release the resources. BUT they still show in SQL Server 2005 Express Edition. I believe they are NOT active and are part of the Pooling system.

The problem is the connections don't seem to be reused, the Pooling system just makes more, so I end up with hundreds of them until no more connections can be created but SQL Server; hence timing out on some attempt to open a connection.

I have experimented with the 'Min Pool Size' and 'Max Pool Size' values in the connection string but the only change is behavior is that I can make more connection showing in SQL Server but the problem still happens anyway.

I am rewriting this application from VB6 to VB.Net. The VB6 version uses SQL Server 2005 Edition too and the connection problem doesn't exist.

Any ideas would be appreciated.

Explain To Noob, Database Uploading

Dec 25, 2007

hi,
From my ealier post I learned that a MDF file can be read and written to even if I did not attach the database in the SQL Sever Management Studio.
Is that behavior because of the connection string where is has 
AttachDBFilename=|DataDirectory|DNN12_24_07.mdf  ,
Is that what "attaches" the database?  This runs on SQL Express2005.
Should I change the connection string  to:
 name="SiteSqlServer"  connectionString="Server=(local);Database=ASPNET;uid=;pwd=;" providerName="System.Data.SqlClient" />
?
Is there a statment in the XML of web.config that defines |DataDirectory| of the original connection string  that points to APP_DATA where the mdf file physically resides?
Thanks in advance?
-KK

Please Explain This.., Why Is PasswordRecovery Creating Another Sqlservr Process....

Jul 3, 2006

Why is the PasswordRecovery control creating another sqlservr process after I successfully enter the user name,  and for a reason I have not found yet it keeps the database in a read only modem then when I answer my security question correctly it gives me the error:
Failed to update database "C:INETPUBWWWROOTVER1.0.0.1APP_DATAASPNETDB.MDF" because the database is read-only.
I read other post regarding the read only message and I don't if there doing the same thing, but why does this happen and what is the solution to this other not using the control?
