  • How to log subsonic3 sql

    - by bastos.sergio
    Hi, I'm starting to develop a new asp.net application based on subsonic3 (for queries) and log4net (for logs) and would like to know how to interface subsonic3 with log4net so that log4net logs the underlying sql used by subsonic. This is what I have so far: public static IEnumerable<arma_ocorrencium> ListArmasOcorrencia() { if (logger.IsInfoEnabled) { logger.Info("ListarArmasOcorrencia: start"); } var db = new BdvdDB(); var select = from p in db.arma_ocorrencia select p; var results = select.ToList<arma_ocorrencium>(); //Execute the query here if (logger.IsInfoEnabled) { // log sql here } if (logger.IsInfoEnabled) { logger.Info("ListarArmasOcorrencia: end"); } return results; }

  • ASP .NET: SQL Server Money Type and .NET Currency Type

    - by Rudi Ramey
    MS SQL Server's Money Data Type seems to accept a well formatted currency value with no problem (example: $52,334.50) From my research MS SQL Sever just ignores the "$" and "," characters. ASP .NET has a parameter object that has a Type/DbType property and Currency is an available option to set as a value. However, when I set the parameter Type or DbType to currency it will not accept a value like $52,334.50. I receive an error "Input string was not in a correct format." when I try to Update/Insert. If I don't include the "$" or "," characters it seems to work fine. Also, if I don't specify the Type or DbType for the parameter it seems to work fine also. Is this just standard behavior that the parameter object with its Type set to currency will still reject "$" and "," characters in ASP .NET? Here's an example of the parameter declaration (in the .aspx page): <asp:Parameter Name="ImplementCost" DbType="Currency" />

  • Run SSIS package from SQL client

    - by Pramodtech
    I deployed my working package on server which is enterprise edition, SSIS installed on it. When I tries to run package by connecting to integration services engine from my desktop SQL client (which doesn't have SSIS installed) I get error "The task "Send Mail Task" cannot run on this edition of Integration Services. It requires a higher level edition." Does it mean that I need to login to the server (RDP) and then run the package? Also, when I schedule the package thru SQL agent it fails saying login time out but my windos auth login works for everything from connecting, deployment. Any clue?

  • Updating Visual FoxPro from SQL Server

    - by David Stein
    I'm trying to update some simple Visual FoxPro tables with SQL Server. I've created a linked server with the following: sp_addlinkedserver @server = 'UTIL', @srvproduct = 'VFP', @provider = 'VFPOLEDB', @datasrc = 'L:\M2MDATA\Util\util.dbc' GO And the following works: select * from UTIL...utcomp However, I cannot use the following statement: update util...utcomp set fmaddress = '123 Elvis Dr.' where fcsqldb = 'M2MDATA01' I receive the error: OLE DB provider "VFPOLEDB" for linked server "util" returned message "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.". Msg 7333, Level 16, State 2, Line 2 Cannot fetch a row using a bookmark from OLE DB provider "VFPOLEDB" for linked server "util". I have the latest version (9.0) installed so I should have the latest provider. Am I doing something wrong? Is it not possible to update VFP from SQL?

  • Problem restoring a SQL Server backup

    - by Elmex
    I have a SQL Server 2008, which is part of a domain. Now I make a backup of a database of this server and restore it on a SQL Server, which is not part of a domain. I have an C# application, which uses this database. On the NON-Domain machine I get now exceptions like this: "Cannot execute as the database prinzipal because the principial "dbo" does not exist, this type of principal cannot be impersonatedm or you don not have the permission" I think, the problem is, that the database owner is a domain user and this user doesn't exist on the target machine (backup machine)!? How can I solve this ?

  • SubSonic 2.x now supports TVP's - SqlDbType.Structure / DataTables for SQL Server 2008

    - by ElHaix
    For those interested, I have now modified the SubSonic 2.x code to recognize and support DataTable parameter types. You can read more about SQL Server 2008 features here: http://download.microsoft.com/download/4/9/0/4906f81b-eb1a-49c3-bb05-ff3bcbb5d5ae/SQL%20SERVER%202008-RDBMS/T-SQL%20Enhancements%20with%20SQL%20Server%202008%20-%20Praveen%20Srivatsav.pdf What this enhancement will now allow you to do is to create a partial StoredProcedures.cs class, with a method that overrides the stored procedure wrapper method. A bit about good form: My DAL has no direct table access, and my DB only has execute permissions for that user to my sprocs. As such, SubSonic only generates the AllStructs and StoredProcedures classes. The SPROC: ALTER PROCEDURE [dbo].[testInsertToTestTVP] @UserDetails TestTVP READONLY, @Result INT OUT AS BEGIN SET NOCOUNT ON; SET @Result = -1 --SET IDENTITY_INSERT [dbo].[tbl_TestTVP] ON INSERT INTO [dbo].[tbl_TestTVP] ( [GroupInsertID], [FirstName], [LastName] ) SELECT [GroupInsertID], [FirstName], [LastName] FROM @UserDetails IF @@ROWCOUNT > 0 BEGIN SET @Result = 1 SELECT @Result RETURN @Result END --SET IDENTITY_INSERT [dbo].[tbl_TestTVP] OFF END The TVP: CREATE TYPE [dbo].[TestTVP] AS TABLE( [GroupInsertID] [varchar](50) NOT NULL, [FirstName] [varchar](50) NOT NULL, [LastName] [varchar](50) NOT NULL ) GO The the auto gen tool runs, it creates the following erroneous method: /// <summary> /// Creates an object wrapper for the testInsertToTestTVP Procedure /// </summary> public static StoredProcedure TestInsertToTestTVP(string UserDetails, int? Result) { SubSonic.StoredProcedure sp = new SubSonic.StoredProcedure("testInsertToTestTVP", DataService.GetInstance("MyDAL"), "dbo"); sp.Command.AddParameter("@UserDetails", UserDetails, DbType.AnsiString, null, null); sp.Command.AddOutputParameter("@Result", DbType.Int32, 0, 10); return sp; } It sets UserDetails as type string. As it's good form to have two folders for a SubSonic DAL - Custom and Generated, I created a StoredProcedures.cs partial class in Custom that looks like this: /// <summary> /// Creates an object wrapper for the testInsertToTestTVP Procedure /// </summary> public static StoredProcedure TestInsertToTestTVP(DataTable dt, int? Result) { DataSet ds = new DataSet(); SubSonic.StoredProcedure sp = new SubSonic.StoredProcedure("testInsertToTestTVP", DataService.GetInstance("MyDAL"), "dbo"); // TODO: Modify the SubSonic code base in sp.Command.AddParameter to accept // a parameter type of System.Data.SqlDbType.Structured, as it currently only accepts // System.Data.DbType. //sp.Command.AddParameter("@UserDetails", dt, System.Data.SqlDbType.Structured null, null); sp.Command.AddParameter("@UserDetails", dt, SqlDbType.Structured); sp.Command.AddOutputParameter("@Result", DbType.Int32, 0, 10); return sp; } As you can see, the method signature now contains a DataTable, and with my modification to the SubSonic framework, this now works perfectly. I'm wondering if the SubSonic guys can modify the auto-gen to recognize a TVP in a sproc signature, as to avoid having to re-write the warpper? Does SubSonic 3.x support Structured data types? Also, I'm sure many will be interested in using this code, so where can I upload the new code? Thanks.

DBMS is SQL Server 2005. T-SQL solution preferred. Thanks in advance, Dave

    - by Tommy Jakobsen
    I'm looking for help to create a query, to solve the following problem: Let's imagine the row: Name StartDate EndDate Payed James 10-10-2010 17-02-2011 860 And heres the schema for the table as requested: payment_details (name VARCHAR(50) NOT NULL, start_date DATETIME NOT NULL, end_date DATETIME NOT NULL, payed FLOAT NOT NULL) Now I need a way to split this row up, so I can see what he pays every month, for his period, a query that returns: Name Year Month Payed James 2010 10 172 James 2010 11 172 James 2010 12 172 James 2011 01 172 James 2011 02 172 There are lots of different customers with different StartDate/EndDate and amount payed, so the query has to handle this aswell. How can I do this in SQL (MS SQL Server 2005)? Help will be much appreciated!

  • SQL datasource for gridview

    - by Karsten
    Hi I want to use a gridview with sorting and paging to display data from an SQL server, the query uses 3 joins and the full text search containstable. The from part of the query uses all 3 tables in the join. What is the best way to do this? I can think of a stored procedure, SQL directly in the SQLDataSource and creating a view in the database. I want good performance and would like to leverage the automatic sorting and paging features of the gridview as much as possible.

  • How to use PredicateBuilder with nested OR conditionals in Linq

    - by tblank
    I've been very happily using PredicateBuilder but until now have only used it for queries with only either concatenated AND statements or OR statements. Now for the first time I need a pair of OR statements nested along with a some AND statements like this: select x from Table1 where a = 1 AND b = 2 AND (z = 1 OR y = 2) Using the documentation from Albahari, I've constructed my expression like this: Expression<Func<TdIncSearchVw, bool>> predicate = PredicateBuilder.True<TdIncSearchVw>(); // for AND Expression<Func<TdIncSearchVw, bool>> innerOrPredicate = PredicateBuilder.False<TdIncSearchVw>(); // for OR innerOrPredicate = innerOrPredicate.Or(i=> i.IncStatusInd.Equals(incStatus)); innerOrPredicate = innerOrPredicate.Or(i=> i.RqmtStatusInd.Equals(incStatus)); predicate = predicate.And(i => i.TmTec.Equals(tecTm)); predicate = predicate.And(i => i.TmsTec.Equals(series)); predicate = predicate.And(i => i.HistoryInd.Equals(historyInd)); predicate.And(innerOrPredicate); var query = repo.GetEnumerable(predicate); This results in SQL that completely ignores the 2 OR phrases. select x from TdIncSearchVw where ((this_."TM_TEC" = :p0 and this_."TMS_TEC" = :p1) and this_."HISTORY_IND" = :p2) If I try using just the OR phrases like: Expression<Func<TdIncSearchVw, bool>> innerOrPredicate = PredicateBuilder.False<TdIncSearchVw>(); // for OR innerOrPredicate = innerOrPredicate.Or(i=> i.IncStatusInd.Equals(incStatus)); innerOrPredicate = innerOrPredicate.Or(i=> i.RqmtStatusInd.Equals(incStatus)); var query = repo.GetEnumerable(innerOrPredicate); I get SQL as expected like: select X from TdIncSearchVw where (IncStatusInd = incStatus OR RqmtStatusInd = incStatus) If I try using just the AND phrases like: predicate = predicate.And(i => i.TmTec.Equals(tecTm)); predicate = predicate.And(i => i.TmsTec.Equals(series)); predicate = predicate.And(i => i.HistoryInd.Equals(historyInd)); var query = repo.GetEnumerable(predicate); I get SQL like: select x from TdIncSearchVw where ((this_."TM_TEC" = :p0 and this_."TMS_TEC" = :p1) and this_."HISTORY_IND" = :p2) which is exactly the same as the first query. It seems like I'm so close it must be something simple that I'm missing. Can anyone see what I'm doing wrong here? Thanks, Terry

  • SQL Server database backup: Network Service file access

    - by Keith Maurino
    When trying to run the following database backup command from my code I get an "Operating system error 5(Access is denied.)" error. This is because the log on account for the SQL Server Windows Service is 'Network Service' and that does not have access to right to this folder. BACKUP DATABASE [AE3DB] TO DISK = 'c:\AE3\backup\AE3DB.bak' My question is, from my code how would I go about figuring out where on the C drive 'Network Service' is allowed to right the backup to? NOTE: This is a distributed application so I cannot easily change the log on for the SQL Server Windows Service to the 'Local System' account that would be able to right to that folder.

  • Best online course for C#/SQL for a professional engineer

    - by Rich
    I know similar questions have been asked, but I've not been able to find information specific to my situation. I'm looking for "continuing education"-type options, specifically a C# and/or SQL course. I'm a software engineering professional with a graduate level computer science degree. So I'm looking for something substantial that will be challenging. I certainly already have me feet wet in both C# and SQL I'm just looking for a more formal training to round out the edges. There is a good chance my company will pay for it if it is reasonably priced so it doesn't have to be free and preferably shouldn't be (a certificate or certification to come out of it would be nice). When I tried Google, all I found were things that sounded like crash courses (like a 3 day course or course for "dummies"), or course that did not seem very credible. Can anyone recommend a course of action for this? Thanks!

Is there a SQL technique to make this easy?

  • hundreds of databases sql server log shipping

    - by Oliver
    SQL Server 2005 Standard 64x, with 300+ tiny databases currently (5MB each), user base adds databases as needed. Want to implement log shipping for warm standby, but not via the wizard, since that looks like it adds 3 jobs (1 on primary, 2 on secondary) for each log-shipped database. Do I try to write my own or use something like Quest's LiteSpeed? Or am I being too squeamish about having hundreds of SQL Server Agent jobs and all of them firing off (or worse, would I have to try to time them)? All advice welcome.

  • Efficient Search function with Linq to SQL

  • Optimize SQL databases by adding index columns

    - by Viktor Sehr
    This might be implementation specific so the question regards how SQL databases is generally implemented. Say I have a database looking like this; Product with columns [ProductName] [Price] [Misc] [Etc] Order with columns [OrderID] [ProductName] [Quantity] [Misc] [Etc] ProductName is primary key of Product, of some string type and unique. OrderID is primary key and of some integer type, and ProductName being a foreign key. Say I change the primary key of Product to a new column of integer type ie [ProductID] Would this reduce the database size and optimize lookups joining these two tables (and likewise operations), or are these optimizations performed automatically by (most/general/main) SQL database implementations?

  • MERGE -v- UPSERT

    - by Kevin Ross
    Hi, I have an application I’m writing in access with a SQL server backend. One of the most heavily used parts is where the users selects an answer to a question, a stored procedure is then fired which sees if an answer has already been given, if it has an UPDATE is executed, if not an INSERT is executed. This works just fine but now we have upgraded to SQL server 2008 express I was wondering if it would be better/quicker/more efficient to rewrite this SP to use the new MERGE command. Does anyone have any idea if this is faster than doing a SELECT followed by either an INSERT or UPDATE?
