  • How much is the database being read from vs written to?

    - by Bill Paetzke
    I'd like to determine if my web app is read-heavy, write-heavy, or somewhere in between. I could take a guess, but I want proof. Is there a query I could run in Sql Server 2005 that would tell me the overall read/write ratio? Are there any caveats I should be aware of? Perhaps it can be found in a DMV query, or the Performance Dashboard, or examining a Sql Profiler trace. I'm not sure exactly how.

  • Insert records using ExecuteNonQuery, showing exception that invalid column name

    - by tina
    Hi all, I am using SQL Server 2008. I want to insert records into a table using ExecuteNonQuery, for that I have written: customUtility.ExecuteNonQuery("insert into furniture_ProductAccessories(Product_id, Accessories_id, SkuNo, Description1, Price, Discount) values(" + prodid + "," + strAcc + "," + txtSKUNo.Text + "," + txtAccDesc.Text + "," + txtAccPrices.Text + "," + txtAccDiscount.Text + ")"); & following is ExecuteNonQuery function: public static bool ExecuteNonQuery(string SQL) { bool retVal = false; using (SqlConnection con = new SqlConnection(System.Web.Configuration.WebConfigurationManager.ConnectionStrings["dbConnect"].ToString())) { con.Open(); SqlTransaction trans = con.BeginTransaction(); SqlCommand command = new SqlCommand(SQL, con, trans); try { command.ExecuteNonQuery(); trans.Commit(); retVal = true; } catch(Exception ex) { //HttpContext.Current.Response.Write(SQL + "<br>" + ex.Message); //HttpContext.Current.Response.End(); } finally { // Always call Close when done reading. con.Close(); } return retVal; } } but it showing exception that invalid column name to Description1 and even it's value which coming from txtAccDesc.Text. I have tried by removing Description1 column, other records are getting inserted successfully. Could you please help me? Thanks.

  • How to perform undirected graph processing from SQL data

    - by recipriversexclusion
    I ran into the following problem in dynamically creating topics for our ActiveMQ system: I have a number of processes (M_1, ..., M_n), where n is not large, typically 5-10. Some of the processes will listen to the output of others, through a message queue; these edges are specified in an XML file, e.g. <link from="M1" to="M3"</link> <link from="M2" to="M4"</link> <link from="M3" to="M4"</link> etc. The edges are sparse, so there won't be many of them. I will parse this XML and store this information in an SQL DB, one table for nodes and another for edges. Now, I need to dynamically create strings of the form M1.exe --output_topic=T1 M2.exe --output_topic=T2 M3.exe --input_topic=T1 --output_topic=T3 M4.exe --input_topic=T2 --input_topic=T3 where the tags are sequentially generated. What is the best way to go about querying SQL to obtain these relationships? Are there any tools or other tutorials you can point me to? I've never done graps with SQL. Using SQL is imperative, because we use it for other stuff, too. Thanks!

  • Can't connect to SQL Server 2005 Express from an ASP.NET C# page

    - by Aviv
    Hey guys, I have an MS SQL Server 2005 Express running on a VPS. I'm using pymssql in Python to connect to my server with the following code: conn = pymssql.connect(host='host:port', user='me', password='pwd', database='db') and it works perfectly. When I try to connect to the server from an ASP.NET C# page with the following code: SqlConnection myConnection = new SqlConnection("Data Source=host,port;Network Library=DBMSSOCN; Initial Catalog=db;User ID=me;Password=pwd;"); myConnection.Open(); When I run the ASP.NET page I get the following exception at myConnection.Open();: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.) I tried restarting the SQL Server but I had no luck. Can anyone point me out to what I'm missing here? Thanks!

  • Need a SQL statement focus on combination of tables but entries always with uinque ID

    - by Registered User KC
    Hi All, I need SQL code to solve the tables combination problem, described on below: Table old data: name version status lastupdate ID A 0.1 on 6/8/2010 1 B 0.1 on 6/8/2010 2 C 0.1 on 6/8/2010 3 D 0.1 on 6/8/2010 4 E 0.1 on 6/8/2010 5 F 0.1 on 6/8/2010 6 G 0.1 on 6/8/2010 7 Table new data: name version status lastupdate ID A 0.1 on 6/18/2010 #B entry deleted C 0.3 on 6/18/2010 #version_updated C1 0.1 on 6/18/2010 D 0.1 on 6/18/2010 E 0.1 off 6/18/2010 #status_updated F 0.1 on 6/18/2010 G 0.1 on 6/18/2010 H 0.1 on 6/18/2010 #new_added H1 0.1 on 6/18/2010 #new_added the difference of new data and old date: B entry deleted C entry version updated E entry status updated C1/H/H1 entry new added What I want is always keeping the ID - name mapping relationship in old data table no matter how data changed later, a.k.a the name always has a unique ID number bind with it. If entry has update, then update the data, if entry is new added, insert to the table then give a new assigned unique ID. However, I can only use SQL with simple select or update statement then it may too hard for me to write such code, then I hope someone with expertise can give direction, no details needed on the different of SQL variant, a standard sql code as sample is enough. Thanks in advance! Rgs KC

  • SQL Server Database In Single User Mode after Failover

    - by jlichauc
    Here is a weird situation we experienced with a SQL Server 2008 Database Mirroring Failover. We have a pair of mirrored databases running in high-availability mode and both the principal and mirror showed as synchronized. As part of some maintenance I triggered a manual failover of the principal to the mirror. However after the failover the principal was now in single-user mode instead of the expected "Principal/Synchronized" state we usually get. The database had been in multi-user mode on the previous principal before this had happened. We ended up stopping all applications, restarting the SQL Server instances, and executing "ALTER DATABASE ... SET MULTI_USER" to bring the database back to the expected "Principal/Synchronized" state in a multi-user mode. Question. Does anyone know where SQL Server stores information about whether a database should be in single-user mode or not? I'm wondering if there is some system database or table that has this setting recorded somewhere. In particular we had an incident once with the database on the original principal (the one I was failing over to) where when trying to detach the database it was put into single-user mode. I'm wondering if that setting is cached somewhere and is the reason that SQL Server put it back into single-user mode after a failover.

  • Working with Decimal fields in SSIS

    - by CoffeeAddict
    I'm using SQL Server 2008 w/SP2. I've got an incoming decimal(9,2) field incoming through my OLE DB transformation to my recordset destination transformation. It's like it's reading it as something other than a decimal? I don't know..I'm not an SSIS guru. So continuing on...the problem I have starts here with me trying to stuff the value into a variable for this decimal field. In a foreach loop, I have a variable to represent this decimal field so I can work with it. The first problem that I believe is pretty well known is SSIS variables do not have a decimal type. And from my own testing and what I've read out there, people are using type object for the variable to make SSIS "happy" with decimal values? It makes mine happy. But, then in my foreach loop, I have a for loop. And inside that I'm using an E*xecute SQL Task transformation*. In it, I need to create a parameter mapping to my variable so I can work with that decimal field in my T-SQL call in here. So now I see a type decimal for the parameter and use it and set that to point to my variable. When I run SSIS and it hits my SQL call, I get this in my output window.: The type is not supported.DBTYPE_DECIMAL So I am hitting a wall here. All I wanna do is work with a decimal!!!

  • Cache data in SQL CE database

    - by user93422
    Background I have an SQL CE database, that is constantly updated (every second). I have a (web) application that allows a user to look at the data in real-time. At some point a user can click "take a snapshot" button, and it will open the snapshot in a different window. And then on that form, there is "print" and "download" buttons that will either generate a page for printing, or will stream the data as CSV file - but same data snapshot has to be used, i.e. I can't go to the DB to get latest data for that. Details SQL CE dabatase is exposed through WCF web service. Snapshot consists of up to 500 records, 10 columns each. Expiration time on the snapshot of 2 hours is sufficient. It is a low-traffic application, so I don't expect more than few (5) connections at the same time. Loosing snapshot is not a big deal, user can simply generate new one. database is accessed by self-hosted WCF web service using Linq-to-SQL. Web site is ASP.NET MVC hosted on UltiDev Cassini. database, and web site are most likely be on the same box, when deployed. The entire app is intranet bound. Problem I need to cache the snapshot of the data at the moment user pressed "take a snapshot" button, so that I can use same data to generate print page, or generate a file for download. Solution 1: Each time there is a need to generate a snapshot, I will create a table in the database. Since there are no temp tables in SQL CE, I will need to clean it up myself. Solution 2: Cache the snapshot in-memory on either DB server, or web server. Question: Is there anything wrong with proposed solutions? Any different solution suggestions?

  • Alternatives to LINQ To SQL on high loaded pages

    - by Alex
    To begin with, I LOVE LINQ TO SQL. It's so much easier to use than direct querying. But, there's one great problem: it doesn't work well on high loaded requests. I have some actions in my ASP.NET MVC project, that are called hundreds times every minute. I used to have LINQ to SQL there, but since the amount of requests is gigantic, LINQ TO SQL almost always returned "Row not found or changed" or "X of X updates failed". And it's understandable. For instance, I have to increase some value by one with every request. var stat = DB.Stats.First(); stat.Visits++; // .... DB.SubmitChanges(); But while ASP.NET was working on those //... instructions, the stats.Visits value stored in the table got changed. I found a solution, I created a stored procedure UPDATE Stats SET Visits=Visits+1 It works well. Unfortunately now I'm getting more and more moments like that. And it sucks to create stored procedures for all cases. So my question is, how to solve this problem? Are there any alternatives that can work here? I hear that Stackoverflow works with LINQ to SQL. And it's more loaded than my site.

  • SQL Server becomes slow after restart

    - by Tobi DM
    We use SQL Server 2005 on an Windwos Server 2008. Ther Server has 48 GB RAM. SQL Server is configured to use 40 GB RAM. There is only one database hosted (About 70 GB). The only app beside SQL Server is our App-Server which connects the clients to the database. Now we encounter the following problem: After a restart of the server our the performance is great. The server grabs the 40 GB RAM wich it is allowed to and then runs fast as hell. But after about 4 weeks the system becomes slower and slower. The execution of statements (seen in the profiler) is raising slowly. But I cannot see that there is something going wrong on the server. CPU usage is at about 20% I/O also seems to be no Problem The process monitor does also not show that there are strange apps or something like that. Eventlog does also have no interessting messages No open transactions or blockings to see We tried already the following things without effect: Droped the cache by using the statements DBCC FreeProcCache DBCC FREESYSTEMCACHE('ALL') DBCC DropCleanbuffers Restarted the Appserver we are using. Restart the sql server service But nothing did help exept restarting the whole server. Any ideas?

  • Transitioning from Domain Authentication to SQL Server Authentication

    - by Albert Perrien
    Greetings all, I've run into a problem that has me stumped. I've put together a database in SQL Server Express, and I'm having a strange permissions problem. The database is on my development machine with a domain user: DOMAIN\albertp. My development database server is set for "SQL Server and Windows Authentication" mode. I can edit and query my database without any problems when I log in using Windows Authentication. However, when I log in to any user that uses SQL Server authentication (Including sa) I get this message when I run queries against my database. SELECT * FROM [Testing].[dbo].[AuditingReport] I get: Msg 18456, Level 14, State 1, Line 1 Login failed for user 'auditor'. I'm logged into the server from SQL Server Management Studio as 'auditor' and I don't see anything in the error log about the login failure. I've already run: Use Testing; Grant All to auditor; Go And I still get the same error. What permissions do I have to set for the database to be usable by others outside of my personal domain login? Or am I looking at the wrong problem? My ultimate goal is to have the database be accessible from a set of PHP pages, using a either a common login (hence 'auditor') or a login specific to a set of individual users.

  • application trying to connect to mirrored sql db

    - by hp
    Hello, We have 4 web servers that host our asp.net (3.5) application. Randomly, we get error messages like : 1) "Login failed for user 'userid'" 2) "A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)" we are running sql2005 and have a principle and a mirror db (sync). When these exceptions are thrown, I look at the SQL error logs on the mirrored db and noticed the failed login messages in there. The principle db is running fine and the other web apps are working great. this will happen for maybe 10 min, then the app pool recycles and it starts hitting the principle db again. Is there a configuration I have incorrect? my theory is that our principle db is forwarding the request to the mirror, but that should never happen. any help??

  • IPad SQLite Push and Pull Data from external MS SQL Server DB

    - by MattyD
    This carries on from my previous post (http://stackoverflow.com/questions/4182664/ipad-app-pull-and-push-relational-data). My plan is that when the ipad application starts I am going to pull data (config data i.e. Departments, Types etc etc relational data that is used across the system) from a webhosted MS SQL Server DB via a webservice and populate it into an SQL Lite DB on the IPad. Then when I load a listing I will pull the data over the line again via a webservice and populate it into the SQL Lite db on the ipad (than just run select commands to populate the listing). My questions are: 1. What is the most efficient way to transfer data across the line via the web? Everyone seems to do it a different way. My idea is that I will have a webService for each type of data pull (e.g. RetrieveContactListing) that will query the db and than convert that data into "something" to send across the line. My question really is what is the "something" that it should be converting into? 2. Everyone talks about odata services. Is this suited for applications where complex read and writes are needed? Ive created a simple iphone app before that talked to an sql server db (i just sent my own structured xml across the line) but now with this app the data calls are going to be a lot larger so efficiency is key.

  • Please recommend the one SQL book for a developer without a lot of SQL experience.

    - by Hamish Grubijan
    I have too many hobbies outside of my profession, so I am hoping to read just one good book, and get a tad better at SQL. My background: took one boring, theoretical class in databases, was exposed to SQL professionally (in addition to several other languages and technologies) for a year and a half. I've done about 5 years of C#/Java stuff professionally. By "professionally" I mean doing it full-time while someone paid me more than $25/hr for it - not necessarily that I created masterpieces along the way :) I want to become better at SQL (coding aspect; DBA is not of particular importance to me right now). I am looking for one book to give me a solid foundation in it. When I needed to learn some C from almost a scratch, I used (and loved) this book: http://www.amazon.com/Programming-Language-2nd-Brian-Kernighan/dp/0131103628 I am hoping to find one just like this for SQL. I am not doing web development now or in a near future, and I am looking for something that is hopefully not specific to any one sub-industry. Thanks in advance.

  • Performance of stored proc when updating columns selectively based on parameters?

    - by kprobst
    I'm trying to figure out if this is relatively well-performing T-SQL (this is SQL Server 2008). I need to create a stored procedure that updates a table. The proc accepts as many parameters as there are columns in the table, and with the exception of the PK column, they all default to NULL. The body of the procedure looks like this: CREATE PROCEDURE proc_repo_update @object_id bigint ,@object_name varchar(50) = NULL ,@object_type char(2) = NULL ,@object_weight int = NULL ,@owner_id int = NULL -- ...etc AS BEGIN update object_repo set object_name = ISNULL(@object_name, object_name) ,object_type = ISNULL(@object_type, object_type) ,object_weight = ISNULL(@object_weight, object_weight) ,owner_id = ISNULL(@owner_id, owner_id) -- ...etc where object_id = @object_id return @@ROWCOUNT END So basically: Update a column only if its corresponding parameter was provided, and leave the rest alone. This works well enough, but as the ISNULL call will return the value of the column if the received parameter was null, will SQL Server optimize this somehow? This might be a performance bottleneck on the application where the table might be updated heavily (insertion will be uncommon so the performance there is not a problem). So I'm trying to figure out what's the best way to do this. Is there a way to condition the column expressions with something like CASE WHEN or something? The table will be indexed up the wazoo as well for read performance. Is this the best approach? My alternative at this point is to create the UPDATE expression in code (e.g. inline SQL) and execute it against the server. This would solve my doubts about performance, but I'd rather leave this in a stored proc if possible.

  • updating a column in a table only if after the update it won't be negative and identifying all updat

    - by Azeem
    Hello all, I need some help with a SQL query. Here is what I need to do. I'm lost on a few aspects as outlined below. I've four relevant tables: Table A has the price per unit for all resources. I can look up the price using a resource id. Table B has the funds available to a given user. Table C has the resource production information for a given user (including the number of units to produce everyday). Table D has the number of units ever produced by any given user (can be identified by user id and resource id) Having said that, I need to run a batch job on a nightly basis to do the following: a. for all users, identify whether they have the funds needed to produce the number of resources specified in table C and deduct the funds if they are available from table B (calculating the cost using table A). b. start the process to produce resources and after the resource production is complete, update table D using values from table C after the resource product is complete. I figured the second part can be done by using an UPDATE with a subquery. However, I'm not sure how I should go about doing part a. I can only think of using a cursor to fetch each row, examine and update. Is there a single sql statement that will help me avoid having to process each row manually? Additionally, if any rows weren't updated, the part b. SQL should not produce resources for that user. Basically, I'm attempting to modify the sql being used for this logic that currently is in a stored procedure to something that will run a lot faster (and won't process each row separately). Please let me know any ideas and thoughts. Thanks! - Azeem

  • ORDERBY "human" alphabetical order using SQL string manipulation

    - by supertrue
    I have a table of posts with titles that are in "human" alphabetical order but not in computer alphabetical order. These are in two flavors, numerical and alphabetical: Numerical: Figure 1.9, Figure 1.10, Figure 1.11... Alphabetical: Figure 1A ... Figure 1Z ... Figure 1AA If I orderby title, the result is that 1.10-1.19 come between 1.1 and 1.2, and 1AA-1AZ come between 1A and 1B. But this is not what I want; I want "human" alphabetical order, in which 1.10 comes after 1.9 and 1AA comes after 1Z. I am wondering if there's still a way in SQL to get the order that I want using string manipulation (or something else I haven't thought of). I am not an expert in SQL, so I don't know if this is possible, but if there were a way to do conditional replacement, then it seems I could impose the order I want by doing this: delete the period (which can be done with replace, right?) if the remaining figure number is more than three characters, add a 0 (zero) after the first character. This would seem to give me the outcome I want: 1.9 would become 109, which comes before 110; 1Z would become 10Z, which comes before 1AA. But can it be done in SQL? If so, what would the syntax be? Note that I don't want to modify the data itself—just to output the results of the query in the order described. This is in the context of a Wordpress installation, but I think the question is more suitably an SQL question because various things (such as pagination) depend on the ordering happening at the MySQL query stage, rather than in PHP.

  • Debugging a local SQL Server 2008 stored proceedure from Visual studio 2008

    - by Ricibob
    Hi all, There are a few posts about this question around but most concern remote debugging - here everything is on same machine. Visual studio 2008. I have a data connection to localhost SQL Server 2008 using Windows authentication with an admin account - this account is a member of sysadmin in SQL server. I double click stored proc and add a break point. I right click and select "Step into stored proceedure". I get the loathed and feared "Canceled by user." in output window. Does anyone know whats doing? Further - right clicking on the data connection shows both "Application debugging" and "Allow SQL/CLR Debugging". I have checked "Enable SQL Server debugging" on the properties of the C# client app. If run that in debug and try to step in to stored proc code "command.ExecuteNonQuery()" then the break points in the stored proc become disabled and are not pulled. After doing this once the right click on stored proc "Execute" and "Step into stored proceedure" are greyed/disabled. To get them back I have to restart visual studio (refresh connection doesn't do it). Any help much appreciated!! Cheers.

  • SQL Server Connection Timeout C#

    - by Termin8tor
    First off I'd like to let everyone know I have searched my particular problem and can't seem to find what's causing my problem. I have an SQL Server 2008 instance running on a network machine and a client I have written connecting to it. To connect I have a small segment of code that establishes a connection to an sql server 2008 instance and returns a DataTable populated with the results of whatever query I run against the server, all pretty standard stuff really. Anyway the issue is, whenever I open my program and call this method, upon the first call to my method, regardless as to what I've set my Connection Timeout value as in the connection string, it takes about 15 seconds and then times out. Bizarrely though the second or third call I make to the method will work without a problem. I have opened up the ports for SQL Server on the server machine as outlined in this article: How to Open firewall ports for SQL Server and verified that it is correctly configured. Can anyone see a particular problem in my code? string _connectionString = "Server=" + @Properties.Settings.Default.sqlServer + "; Initial Catalog=" + @Properties.Settings.Default.sqlInitialCatalog + ";User Id=" + @Properties.Settings.Default.sqlUsername + ";Password=" + @Properties.Settings.Default.sqlPassword + "; Connection Timeout=1"; private DataTable ExecuteSqlStatement(string command) { using (SqlConnection conn = new SqlConnection(_connectionString)) { try { conn.Open(); using (SqlDataAdapter adaptor = new SqlDataAdapter(command, conn)) { DataTable table = new DataTable(); adaptor.Fill(table); return table; } } catch (SqlException e) { throw e; } } } The SqlException that is caught at my catch is : "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding." This occurs at the conn.Open(); line in the code snippet I have included. If anyone has any ideas that'd be great!

  • PASS Conference 2011 Topic: Multitenant Design and Sharding with SQL Azure

    - by Herve Roggero
    I am really happy to announce that I have been accepted as a speaker at the 2011 PASS Conference in Seattle. The topic? It will be about SQL Azure scalability using shards, and the Data Federation feature of SQL Azure. I will also talk extensively about the community open-source sharding library Enzo SQL Shard (enzosqlshard.codeplex.com) and show how to make the most out of it. In general, the presentation will provide details about how to properly design an application for sharding, how to make it work for SQL Server, SQL Azure, and how to leverage the upcoming Data Federation technology that Microsoft is planning. The primary objective is to turn sharding an implementation concern, not a development concern. Using a library like Enzo SQL Shard will help you achieve this objective. If you come to PASS Summit this year, come see me and mention you saw this blog!
