• Problem with update sql with excel

  - by phenevo

  Hi, I have a problem with this query: Update Provinces Set Provinces.DefaultName=T2.Defaultname from Provinces inner join OPENROWSET('Microsoft.Jet.OLEDB.4.0', 'Excel 8.0;Database=C:\provinces.xlsx;HDR=YES', 'SELECT Code, Defaultname FROM [Arkusz1$]') T2 On Provinces.Code = t2.Code where Provinces.Code = T2.Code I get error: Msg 7399, Level 16, State 1, Line 1 The OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "(null)" reported an error. The provider did not give any information about the error. Msg 7303, Level 16, State 1, Line 1 Cannot initialize the data source object of OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "(null)". What is a reason of this unpleasent situation ?

• Entity Framework How to specify paramter type in generated SQL (SQLServer 2005) Nvarchar vs Varchar

  - by Gratzy

  In entity framework I have an Entity 'Client' that was generated from a database. There is a property called 'Account' it is defined in the storage model as: <Property Name="Account" Type="char" Nullable="false" MaxLength="6" /> And in the Conceptual Model as: <Property Name="Account" Type="String" Nullable="false" /> When select statements are generated using a variable for Account i.e. where m.Account == myAccount... Entity Framework generates a paramaterized query with a paramater of type NVarchar(6). The problem is that the column in the table is data type of char(6). When this is executed there is a large performance hit because of the data type difference. Account is an index on the table and instead of using the index I believe an Index scan is done. Anyone know how to force EF to not use Unicode for the paramater and use Varchar(6) instead?

• SQL Server Import table keeping default values

  - by Chrissi

  I am importing a table from one database to another in SQL Server 2008 by right-clicking the target database and choosing Tasks Import Data... When I import the table I get the column names and types and all the data fine, but I lose the primary key, identity specifications and all the default values that were set in the source table. So now I have to set all the default values for each column again manually. Is there any way to get the default values with the import, or even after with a Query? I am VERY new to this and flailing in the dark, so forgive me if this is a really stupid question...

• Daily/Weekly/Monthly Record Count Search via StoredProcedure

  - by user270960

  Using MS SQL Server.I have made a Stored Procedure naming "SP_Get_CallsLogged". I have a table named "TRN_Call", and it has one column named "CallTime" which is a DateTime. I have a web-page in my application where the User enters:- 1.StartDate (DateTime) 2.EndDate (DateTime) 3.Period(Daily/Weekly/Monthly) (varchar) (from DropDownList) I want to get the Record Count of those calls in my table *TRN_Call* on the basis of the specified Period(Daily/Weekly/Monthly) selected by user in the DropDownList. e.g. StartDate ='1/18/2010 11:10:46 AM' EndDate ='1/25/2010 01:10:46 AM' Period =Daily So the record count between these above mentioned dates(StartDate+EndDate) should come in a manner so that I can refer to those counts separately i.e. the following:- Date 1/18/2010 Records Found 5 Date 1/19/2010 Records Found 50 Date 1/20/2010 Records Found 15 Date 1/21/2010 Records Found 32 Date 1/22/2010 Records Found 12 Date 1/23/2010 Records Found 15 Date 1/24/2010 Records Found 17 Date 1/25/2010 Records Found 32 and send those Counts to the Web Application so that these counts could be listed then in the Crystal Reports.

• tsql proc logic help

  - by bacis09

  I am weak in SQL and need some help working through some logic with my proc. Three pieces: store procedure, table1, table2 Table 1 stores most recent data for specific IDs Customer_id status_dte status_cde app_dte 001 2010-04-19 Y 2010-04-19 Table 2 stores history of data for specific customer IDs: For example: Log_id customer_Id status_dte status_cde 01 001 2010-04-20 N 02 001 2010-04-19 Y 03 001 2010-04-19 N 04 001 2010-04-19 Y The stored proecure currently throws an error if the status date from table1 is < than app_date in table1. If @status_dte < app_date Error Note: @status_dte is a variable stored as the status_dte from table1 However, I want it to throw an error when the EARLIEST status_dte from table 2 with a status_cde of 'Y' is less than the app_dte column in table 1. Keep in mind that this earliest date is not stored anywhere, the history of data changes per customer. Another customer might have the following history. Log_id customer_Id status_dte status_cde 01 002 2010-04-20 N 02 002 2010-04-18 N 03 002 2010-04-19 Y 04 002 2010-04-19 Y Any ideas on how I can approach this?

• SQL Server, Generate scripts, unencrypted stored procedures only

  - by PeterO

  I have a SQL Server database with 3195 stored procedures. Most (approx 90%) of the stored procedures are encrypted (it's a 3rd party app) but there are many that are not encrypted (added by consultants later). I need to get an overview of the unencrypted stored procedures created by consultants and then apply fixes so that they can work with UTC time. I use Generate Scripts and select only stored procedures but that fails. I assume that is because the first stored procedure that it tries to write out is encrypted. Is there a way to write out the approx 300 stored procedures that are not encrypted?

• SQL IDENTITY COLUMN

  - by andreas

  Hey guys i am have an sql table which is basically a statement. Now lest say the records i have in my table have a date and an identity column which is autonumbered and defines the order which the transactions are displayed in the front end to the client. The issue is during an insert some of the data have gone missing and some transactions between two dates are missing. I need to insert the data into the table but i need to insert them between the dates and not at the end of the table.If i do a a normal insert now the data will appear at the end of the table and not at the date i specify because the identity column is autonumbered and cannot be updated. Thanks

• How to use a variable to specify filegroup in MSSQL

  - by gt

  I want to alter a table to add a constraint during upgrade on a MSSQL database. This table is normally indexed on a filegroup called 'MY_INDEX' - but may also be on a database without this filegroup. In this case I want the indexing to be done on the 'PRIMARY' filegroup. I tried the following code to achieve this: DECLARE @fgName AS VARCHAR(10) SET @fgName = CASE WHEN EXISTS(SELECT groupname FROM sysfilegroups WHERE groupname = 'MY_INDEX') THEN QUOTENAME('MY_INDEX') ELSE QUOTENAME('PRIMARY') END ALTER TABLE [dbo].[mytable] ADD CONSTRAINT [PK_mytable] PRIMARY KEY ( [myGuid] ASC ) ON @fgName -- fails: 'incorrect syntax' However, the last line fails as it appears a filegroup cannot be specified by variable. Is this possible?

• Obtain Update Table Lock at start of Stored Procedure in SQL Server

  - by Jim Hurne

  I'm writing a SQL Server stored procedure in which I want to lock a table for update before executing the body of the stored procedure. I don't want to prevent other processes from reading the table, but I do want to prevent other processes updating the table. Here is my first attempt: CREATE PROCEDURE someProcedure BEGIN SET TRANSACTION ISOLATION LEVEL READ COMITTED BEGIN TRANSANCTION SELECT COUNT(*) FROM TheTable WITH (UPDLOCK, TABLOCK) -- Pause procedure so that we can view the locks with sp_lock WAITFOR DELAY '00:15' -- Do stuff COMMIT END When I execute the stored procedure, and invoke sp_lock, I see that the table is indeed locked. However, it's locked with an Exclusive lock instead of an update lock: spid | dbid | ObjId | IndId | Type | Resource | Mode | Status ------------------------------------------------------------------ 63 | 10 | 233208031 | 0 | TAB | | X | GRANT How can I get an update (U) lock instead?

• C# ASP.NET update SQL database with values from text boxes

  - by Sir Graystar

  Here's what I have. User enters values into text boxes (personal information etc.) and then presses a save changes button. The values in these text boxes get stored in an SQL database. The problem I have is that when updating the database using the values from the text boxes, the page refreshes and the values in the text boxes are lost (or rather they return to the values that are already in the database as the data from the database is loaded into the text boxes on Page_Load). When I update the database using valuse stored in variables it all works fine. What is the best way to update with the values from the text boxes?

• Prevent sqlite INJECTION ATTACKS on your own iPhone?

  - by Bonnie

  I always take precautions regarding SQL INJECTION ATTACKS when data is saved between someone's iPhone and a remote database on the cloud. But is it also necessary to do the same... when just saving data (using sqlite) from someone's cell phone, to a database that's just on their own phone? What's the worse they can do? Delete their own data (or tables) on their own phone? (If they really try hard enough.) Thanks.

• Processing a property in linq to sql

  - by Mostafa

  Hi It's my first LINQ TO SQL Project , So definitely my question could be naive . Till now I used to create new property in Business Object beside of every DateTime Property , That's because i need to do some processing in my DateTime property and show it in special string format for binding to UI Controls .Like : private DateTime _insertDate; /// /// I have "InertDate" field in my Table on Database /// public DateTime InsertDate { get { return _insertDate; } set { _insertDate = value; } } // Because i need to do some processing I create a readonly string property that pass InsertDate to Utility method and return special string Date public string PInsertDate { get { return Utility.ToSpecialDate(_insertDate); } } My question is I don't know how to do it in LINQ . I did like follow but i get run time error. ToosDataContext db = new ToosDataContext(); var newslist = from p in db.News select new {p.NewsId,p.Title,tarikh =MD.Utility.ToSpecialDate( p.ReleaseDate)}; GridView1.DataSource = newslist; GridView1.DataBind();

• SQL Server Query Slow from PHP, but FAST from SQL Mgt Studio - WHY???

  - by Ray

  I have a fast running query (sub 1 sec) when I execute the query in SQL Server Mgt Studio, but when I run the exact same query in PHP (on the same db instace) using FreeTDS v8, mssql_query(), it takes much longer (70+ seconds). The tables I'm hitting have an index on a date field that I'm using in the Where clause. Could it be that PHP's mssql functions aren't utilizing the index? I have also tried putting the query inside a stored procedure, then executing the SP from PHP - the same results in time difference occurs. I have also tried adding a WITH ( INDEX( .. ) ) clause on the table where that has the date index, but no luck either. Here's the query: SELECT 1 History, h.CUSTNMBR CustNmbr, CONVERT(VARCHAR(10), h.ORDRDATE, 120 ) OrdDate, h.SOPNUMBE OrdNmbr, h.SUBTOTAL OrdTotal, h.CSTPONBR PONmbr, h.SHIPMTHD Shipper, h.VOIDSTTS VoidStatus, h.BACHNUMB BatchNmbr, h.MODIFDT ModifDt FROM SOP30200 h WITH (INDEX (AK2SOP30200)) WHERE h.SOPTYPE = 2 AND h.DOCDATE >= DATEADD(dd, -61, GETDATE()) AND h.VOIDSTTS = 0 AND h.MODIFDT = CONVERT(VARCHAR(10), DATEADD(dd, -1*@daysAgo, GETDATE()) , 120 ) ;

• LINQ to SQL stored procedures with multiple results in Visual Studio 2008

  - by Jeremy

  I'm using visual studio 2008 and I've created a stored procedure that selects back two different result sets. I drag the stored proc on to a linq to sql dbml datacontext class, causing visual studio to create the following code in the cs file: [Function(Name="dbo.List_MultiSelect")] public ISingleResult<DataAccessLayer.DataEntities.List_MultiSelectResult> List_MultiSelect() { IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod()))); return ((ISingleResult<DataAccessLayer.DataEntities.List_MultiSelectResult>)(result.ReturnValue)); } Shouldn't the designer generate the code to use IMultipleResults? Or do I have to hand code that?

• how to compare/validate sql schema

  - by Ron Harlev

  I'm looking for a way to validate the SQL schema on a production DB after updating an application version. If the application does not match the DB schema version, there should be a way to warn the user and list the changes needed. Is there a tool or a framework (to use programatically) with built-in features to do that? Or is there some simple algorithm to run this comparison? Update: Red gate lists "from $395". Anything free? Or more foolproof than just keeping the version number?

• Use delegate for Projection in Linq to SQL

  - by Redeemed1

  I have code something like this in an IRepository implementation in Linq to Sql: var newlist = from h in list where h.StringProp1 == "1" select new MyBusinessBO{ firstProp = h.StringProp1, secondProp = h.StringProp2 }; The projection into MyBusinessBO is not difificult but when the Business Object has many properties the projection code becomes very lengthy. Also, as the projection can occur in several places in the Repository we break the DRY principle. Is there any way to abstract out the projection or replace it with a delegate? I.e. replace the code firstProp = h.StringProp1, secondProp = h.StringProp2 with something reusable?

• Formatting when copying SQL data and pasting in Excel

  - by Mary-Chan

  I want to copy a sql result set and paste it in Excel. But the data I paste in to the spreadsheet doesn't want to recognize Excel formatting. So if I change a column to currency, it doesn't do anything. But...if I double click on a cell, THEN it applies the currency format. But only to that cell. How can I make it automatically recognize the Excel format? I must be something I'm missing. Hopefully somebody can help. :-)

• Getting a value from a row at particular time

  - by Swetha Bindu

  I had a row in my database: starttime:4/6/2012 2:00pm, Endtime:31/12/9999, name:"swetha", status:"open"..... When I update this row I changed the starttime to the current time (getdate()) and have no issues. I am running a Windows Service each day at 1am to modify a value in the row. I would like to know the status of my row at 4/6/2012 11:59 pm when my service runs. There is no need to do an update at 4/6/2012 11:59 pm and the last update may be at any time of the day however my requirement is to get the status value at 4/6/2012 11:59 pm. I would like to have the query in SQL Server 2008. Can anyone please help me to find a solution?

• MS-SQL statement to replace/delete sub-strings

  - by StefanE

  Hi, I have a table with 6 columns containing HTML content with some markups in it and now when moving to a new designed site most of this HTML code has to be deleted. More or less all tags except and . Is there a nice way of doing this, identify all tags end delete them within the data? I'm sure there are no < symbols in the test so a regular expression would maybe work? My alternative is to fecth every row, process it and update the database but I'm guessing this is possible to do in SQL directly. Thanks, Stefan

• SQL Query: Using Cursors

  - by user2953138

  I need some directions for SQL Server & Cursors: I have a table named Order: OrderID Item Amount 1 A 10 1 B 1 2 A 5 2 C 4 2 D 21 3 B 11 I have a second table named Storage: Item Amount A 40 B 44 C 20 D 1 For every OrderID, I want to check if enough items are available. If not, I want to return an error message. How can this be done with Cursors at all? Are nested cursors the solution to this? My main issue is to understand how I can fetch the OrderID as actual "Group" of ID=1, 2, 3 etc. instead of line by line

• Recursive query question - break rows into columns?

  - by Stew

  I have a table "Families", like so FamilyID PersonID Relationship ----------------------------------------------- F001 P001 Son F001 P002 Daughter F001 P003 Father F001 P004 Mother F002 P005 Daughter F002 P006 Mother F003 P007 Son F003 P008 Mother and I need output like FamilyID PersonID Father Mother ------------------------------------------------- F001 P001 P003 P004 F001 P002 P003 P004 F001 P003 F001 P004 F002 P005 P006 F002 P006 F003 P007 P008 F003 P008 In which the PersonID of the Father and Mother for a given PersonID are listed (if applicable) in separate columns. I know this must be a relatively trivial query to write (and therefore to find instructions for), but I can't seem to come up with the right search terms. Searching "SQL recursive queries" has gotten me closest, but I can't quite translate those methods to what I'm trying to do here. I'm trying to learn, so multiple methods are welcome, as is vocabulary I should read up on. Thanks!

• Query to return internal details about stored function in MS-SQL database

  - by Anthony

  I have been given access to a ms-sql database that is currently used by 3rd party app. As such, I don't have any documentation on how that application stores the data or how it retrieves it. I can figure a few things out based on the names of various tables and the parameters that the user-defined functions takes and returns, but I'm still getting errors at every other turn. I was thinking that it would be really helpful if I could see what the stored functions were doing with the parameters given to return the output. Right now all I've been able to figure out is how to query for the input parameters and the output columns. Is there any built-in information_schema table that will expose what the function is doing between input and output?

• LINQ-to-SQL class doesn't implement INotifyPropertyChanging & INotifyPropertyChanged if pulling from

  - by Traples

  I modified my data source in my LINQ-to-SQL class (by the old delete and drag back in method), and was surprised to see the INotifyPropertyChanging & INotifyPropertyChanged interfaces no longer implemented in the generated classes (MyDb.designer.cs). The methods for the individual fields went from looking like this... [Column(Storage="_Size", DbType="NVarChar(100)")] public string Size { get { return this._Size; } set { if ((this._Size != value)) { this.OnSizeChanging(value); this.SendPropertyChanging(); this._Size = value; this.SendPropertyChanged("Size"); this.OnSizeChanged(); } } } To looking like this... [Column(Storage="_Size", DbType="NVarChar(100)")] public string Size { get { return this._Size; } set { if ((this._Size != value)) { this._Size = value; } } } Any ideas on why this happens and how it will affect my application?
