ADO.NET :: Managing TypedDataSets When There Is A Change In Backend Table / Stored Procedure / Database Schema
Sep 15, 2010
if there is any easier way to synchronize the TypedDataSets with the chages made to backend Table / Stored Procedure schema. I use Typed DataSets in my project extensively and I found them very useful and easier to code, but difficult to maintain
The difficuly I have always faced is whenever there is a change in a backend database table structure or stored procedure that is linked to any of the Typed DataSet in our project requires to recreate whole DataSet again by scrapping the old one. The backend changes will not be reflected unless and untill you recreate the whole stuff again.
Is there any easier way to synchronize those typed datasets with the changes made to backend database schema or any other workaround that will not required to recreate the whole DataSet again.
I am trying to figure out if it's possible to resolve schemas for tables within a Stored Procedure. If not, I was wondering if maybe I can find a better solution here. Here is my scenario.
I have an application that will access a SQL database that will be used by different organizations within my company. The database will only a have a few tables but it has many stored procedures that will call them. The different organizations will each have their own SQL User and schema with the tables duplicated for each schema. While each schema will have its own set of tables to separate data between the organizations, I do not want to make a copy of each stored procedure since the logic will be the same. I would like the schema to be resolved by the user that is accessing the database. If I do inline SQL within the application it resolves with no problem but using a Stored Procedure will always run it under the owner of the sp, causing it to throw an invalid table name error.
Is there anyway to resolve this or is this just the functionality of MS SQL? Are there any workarounds out there (other than Dynamic SQL) that I can use?
I moved my website to the hosting control panel (ASP.NET files and SQL 2005 database).The hosting provider does not allow the SQL stored procedures with schema name 'dbo' (for example - the provider does not allow 'dbo.aspnet_CheckSchemaVersion'). So, all'dbo' schema became 'myusername' ie 'myusername.aspnet_CheckSchemaVersion' in theSQL database. Now, when I open my website, I am getting the following error -Could not find stored procedure 'dbo.aspnet_CheckSchemaVersion'.What change should I make in my ASP.NET (C#) to make the website to look for 'myusername.aspnet_CheckSchemaVersion', instead of 'dbo.aspnet_CheckSchemaVersion'?
I have created one stored procedure which runs on 5000 users in tbluser table with some filter condition in database.There are 4 filtering condition(FC1,FC2,FC3,FC4).Filtering condition has some ListBox and dropdown list of department and countries.I want output as given below:
ID Name StaffNo department Points 1 KK 111 dep1 2 2 NN 222 dep2 1 3 DD 333 dep3 4
I got ID,Name,StaffNo,department in resultset but not points.
points calculation would be based on filtering condition like
if FC1 matched user gained point 1,if both FC1 and FC2 matched user gained 2 point,if both FC1 ,FC2 and FC3 matched user gained 3 point etc.
--in stored procedure i m using dynamic query DECLARE @SQL VARCHAR(2000) SET @SQL = 'SELECT U.UserID, U.StaffNo,U.FirstName+'' ''+ U.LastName AS EmployeeName,''?'' AS Points FROM tblUser U '[code]....
all filtering condition are implemented with OR logic.
I have few inline sql statements with some arrays and if loops. I want to change them all into one stored procedure in SQL server 2005.
As i am learning SQL, i have got no idea about how it should be done with arrays and if loops. Is that possible to send arrays into stored procs or is there any other solution.
I'm working on a new project where I have the luxury of working from a Model to Database approach using Entity Framework 4.
The project I'm working on is taking an agile approach where different phases will be rolled out over time.
Will the Model First approach work in my case? I noticed when you "Generate Database from Model" it recreates the entire schema from scratch which will obviously wipe all the data that is in the db. I was hoping for a more "Update Database from Model" approach where the db would just be altered to reflect the changes rather than recreated
Initially, I have tried to use stored procedure. But I changed my mind and preferred to call sql query in codebase with command text. However, it stills tries to find initially-called stored procedure (which is neither called or exists).I think that it is related caching. But I tried it with different browsers it did not work.What might be the reason?
I'm not so familiar with stored procedures but I'm interesting in moving most of my web selects to stored procedures. I'm working with .net based website and all my data access is something like this:
[Code]....
But now I want to improve some process and make tunings. For that I want to use stored procedures, so instead of the "SELECT ...." sentence I'll put stored procedure name. My problem is how to return a table from one.
i want to display image which is stored in some folder and its path is stored in database table. i used your link [URL] for the same but i am not storing any thing like data column in my table and have passed name column to Byte[]and so its giving datatype error there. what is the way to convert it to byte?

i would like to retrieve data from two table, how can i create a temp table and then insert data from two different table.and then use the temp table to join other table in stored procedure.if i want to select same data from two table, how can i select all distinct data from two table into temp table
Using asp.net MVC in c#, I am making a call to a stored procedure using Linq into my SQL Members table. I have no internal caching on the application, already checked to make sure it is turned off.
Test case:I have my username set to test1. From the website I change my username to test2. The website still shows test1. I go to Management Studio and run my stored procedure called MemberByEmail, it shows test2 correctly.I start simple, refresh my page to see if it's browser cache, still test1. I go to debugging and walk through the code and find that it goes correctly all the way to here to call the database:
/// <summary>Method that is mapped to the dbo.MemberByEmail database procedure.</summary> /// <returns></returns> [System.Data.Linq.Mapping.Function(Name="dbo.MemberByEmail")][code]...
Again I ran the stored procedure through Management Studio, and it came up with test2 as the username. I waited for 15 minutes, refreshing the web page every 5 or so, and it never cleared and served the correct test2 from the db. The last strange piece, I ran IISReset and refreshed the page, test2 was returned.
UPDATE: I created a console application to take out the web piece of it. The problem is the same when accessing directly from a console app also, no change.
I've written a stored procedure which uses a table variable. The stored procedure is shown below:
[Code]....
The table variable @CaseNumbers is declared, and is a bunch of values are inserted using a table-valued function called SplitStringIntoInts. At this point I can select from @CaseNumbers and this works fine.But when I try to join onto @CaseNumbers, the name '@CaseNumbers' in the ON clause is highlighted with the error 'Must declare scalar variable @CaseNumbers'. What?! It's not scalar, I declared it ages ago and I have used it since!
my stored procedure is always extract some data into temp table such as"select name,address,content into #TEMP1 from table1,table2,table3" finally, select another table together with #TEMP1 to extract all desire data from one queryselect T.name,T.address,T.content,C.other from #TEMP1 T, otherTable C where T.ID=C.IDI would like to ask if i want to join one more table T2 into final query with "otherTable left C outer join on C.ID=T2.ID"
i m using ##Temp Table in stored procedure..it gives this error There is already an object named '##people' in the database.in two codition1.in case of multisession2. if transaction drop in between even i drop Table in Last in stored procedure..what can i use in place of temp table to hold data for a time being
I am a rookie developer here and I have tried looking around for an answer but I am little confused. I have a stored procedure that calls multiple stored procedures when I go to create a new contact.[Code]....
I though I could use the OUTPUT Command to copy out the NewContactID but I am getting all kinds of syntax errors. I am confused as to what I am missing here.
I am using table adapter in a dataset type (.xsd) file mapping to database. But I found after I created a new stored procedure in database and use table adapter mapping to the new stored procedure, I got method not found error like
Method not found: 'PO_GetNewOrdersSummaryDataTable BizTalk.Application.DataAccess.DatalayerTableAdapters.PO_GetNewOrdersSummaryTableAdapter.GetDataByCompletedDays(System.String, System.String, System.Nullable`1<Boolean>, System.Nullable`1<Boolean>, System.Nullable`1<Int32>)'.
on the testing server. But it is fine if I run the web application on my local dev machine and another machine we use it for building application before deployment. Does anyone know what could cause this problem on testing server? It works fine before I created the new method
GetDataByCompletedDays in PO_GetNewOrdersSummaryTableAdapter.
This may not be the correct place to put this as it is both a stored procedure AND Visual Studio 2008 problem.
I have the following stored procedure:
[Code]....
I have been mokeying around with it because of what is happening. I have a dataset, call it dataset1. I drag this stored procedure onto the dataset. I EXPECT a datatable to appear, instead the data set adds this store procedure to the queries table adapter and sets the exec mode to 'NonQuery' which unless I am very mistaken, means "don't expect a dataset back from this' when in fact you DO expect a dataset back from this.
The SQL server is a Windows 2000 Server running SQL 2000. It has never caused us a moments grief since we set it up oh-so-many years ago.
If I connect to a different database and drag a query into the same dataset I get a datatable as I expect. I cannot see where / how this procedure could be wrong. The query when executed returns exactly the data I expect, in the format I expect (looks like a table, acts like a table in the Query analyzer).
