using the sqlclient object..
Creating a system with web front end and SQL backend (microsoft obviously). I have tried using the asp.netsqlprovider but i can;t as i am only allowed one database on the server, so i then tried to update my current database with the triggers to input the schema into the already existing database.Next step i create my own table with two simple fields of username and password and try and authenticate that way, i can't get that to work either.
I ahve limited permissions on the network as i am a University Student. I really don't know what to do. Never had to create a log on system before and i thought it would be far simpler than this. I ahve used Microsoft's sqlprovider schema before and it worked fine. I have also authenticated via IIS and AD too before. I can't do any of those two in this instance it seems.I need an alternative for logging in users, if needs be in can be crude. I also still need to have some kind of two different views too for logged in users and not logged in users, but that can change if needs must.Don't let me down people, haha. Think this posts in the correct place, i could not find another one i thought could be more relevant.
I recently installed the latest Oracle Data Provider for .NET(ODP.NET 11.2.0.1.2), due to the fact that Microsoft Oracle Client is deprecated. Ever since the new installation, my SqlDataSource control stopped working. When I try to configure the data source of the SqlDataSource and test the connection, it always gives me the following error message:Database schema could not be retrieved for this connection. Please make sure the connection settings are correct and that the database is online.
OCIEnvCreate failed with return code -1 but error message text was not available. at DataObjectSupport(721,6)
I know for sure the connection settings are definitely correct and the database is online for sure, because any databinding I did manually works perfectly well. I can manually bind to a Gridview, ListBox controls and display the data without any problem. The only problem I have is using the SqlDataSource. This is painful because Gridview and Listview have a lot of cool built-in features. When you databind the controls in the code behind file, you lose all the features.
I have added ASPNET to the Oracle home directory and granted it full control access and retarted the computer but it doesn't work. I'm using Visual Studio 2010 and the database is Oracle 10g. Does anybody know why I'm having problem with SqlDataSource only?
I've created a Data Base project with some CLR functions and stored procedures.
I'd like to deploy the assembly under different schema then the default dbo.
Is it possible?
I am looking for a fast way (either by script or Query statements) that would enable me uniquely extract some tables from my database schema.
The tables I wish to extract have some unique columns like x and y coordinate columns and i want to extract only the tables that have these coulmns in them.
My database schema is very large with 100s of tables that i cant just go through the tables one by one.
I have two columns first name and last name , that have duplicates, how can i remove the duplicates and only leave the distinct members intact?
View 6 RepliesI have a record created date stored as" 2010-05-16 15:44:18.700" in sql server database. When I read this date it gets converted to "5/16/2010 3:44:18 PM" . How should I read it so that I don't loose the ending '700' value so that it gets written exactly to another database.Code for reading the record:
String myConn = ConfigurationManager.ConnectionStrings["DBConnectionString"].ToString();
SqlConnection con = new SqlConnection(myConn);
SqlCommand cmd = new SqlCommand();[code].....
I have a SQL Server 2008 DB with many tables filled with data and I used SQL Server Management Studio to generate a SQL dump by using the Script Wizard : Tasks -> Generate Scripts -> Script All objects in the selected database and also selecting the option to Script Data. I made sure to change the value of "Script for Server Version" to "SQL Server 2008". Then I created a new DB and ran the SQL dump on the new DB to generate an identical copy of the old DB. Then I assigned permissions to my default user to the new DB. Then I changed the connection string on my ASP.NET application to use the new DB. But when I run it, it throws the following exception -
Server Error in '/myapp' Application. The 'System.Web.Security.SqlMembershipProvider' requires a database schema compatible with schema version '1'. However, the current database schema is not compatible with this version. You may need to either install a compatible schema with aspnet_regsql.exe (available in the framework installation directory), or upgrade the provider to a newer version.

How to write xml schema for xml file
how can i write a sql to execute the file at specific time sql server database.
View 3 RepliesI have two datasets, one is populated from a SQL Database on my server, the other is populated from an XML file passed from the client server.Both datasets are identical in structure (and potentially the same in data as well)hat I need to be able to do is as follows:-Compare Dataset1 against Dataset2 and record which rows are missing from Dataset2 (based on 2 primary fields)Compare Dataset2 against Dataset1 and record which rows are missing from Dataset1 (based on 2 primary fields)Compare Dataset1 against Dataset2 and record any rows which are different ((based on 2 primary fields always being the same and 3 fields being potentially different)
View 2 RepliesI already may have access to the solution i am after but cant find a way to keep the data and schema the same during deployment, ie development server SQL database to be the same thing as what i put on the sql server host during the deployment of the web application
i was using Quest Rocket compare to sync data and schema, it worked fine but they dropped that project with the intro by MS of VS08, ie the Quest plug-in works in VS05 but not in VS08 anyway, i probably have the solution I am after at my disposal due to my MSDN subscription which includes SQL server products, but my first problem there, is that i cant identify which MS tool to download and to use that will do the same thing or better than the Quest Rocket compare product,
i believe the solution i need is the full version of SQL Management Studio (which i think i have due to my MSDN subsctiption but my second problem 2) is i cant find in that full studio download in my MSDN subscriber area) also is it only the full verison of SQL Mgt studio and not the Express version that might have the "sync" capabiltiy, is that correct? or is there a way (I am a intemediate on SQL techonologies), within the Express Management Studio to painlessly sync both the schema and the data? I am using VS08 Pro, so mayber there is a way in the VSIDE to do the syncing, I think i tried the Publisher but ran into difficulties, am going to try that again and repost here what those difficulties were,
SO really just after a nice tool or utility that will keep SQL database schema and data the same during the deployment process for the web application i build, kinda urgent to as am buried and dont have time to breath.
I have a C#/Asp.net web application which caches SQL DB schema information. Is there a way that I can determine what child relationships a given table has? I have looked into using the DataTable.ChildRelations property, but it is never populated with items unless i manually create a relationship using the .add property. I also have access to DataColumn information for each column in the database.

View 5 RepliesI have created database in sql server 2005 using Snowflake model.
Problem :
There is 1 fact table and 3 dimension tables.
Suppose Fact Table has cols : sales_person_id, cust_id, product_id and dimension tables as per id s defined in fact table.
Suppose i want to update products in product table, i am able to do so.
but i can not update product_id in Fact Table because remaining two field will be NULL.
I have the code below:
SqlConnection sqlConnection = new SqlConnection(selectedConnStr);
sqlConnection.Open();
SqlCommand sqlCommand = new SqlCommand("SELECT * FROM " + tableName, sqlConnection);
schema = sqlCommand.ExecuteReader(CommandBehavior.CloseConnection).GetSchemaTable();
Just want to know how can I get the foreign keys from schema?
I was just wondering if anyone has ever had to port the schema across? Are there any experts that could pitch their opinions on the achievability of this (mad) idea? I'm using the IBM Migration Toolkit and as expected its throwing a bunch of translation errors some of which were relatively easy to solve (vendor specific function calls for example) and some will take quite a while to pin down and work round.... however this is not my main concern.
If completed I expect I am going to have to basically rework all the System.Web.Profile/Roles/Membership namespace classes etc to work round the SQL limitations of informix (i.e. IDS11.x SQL server doesnt have a DEFAULT (newguid()) so that would have to be put into the calling method) (and any MVP comments really as I can slap my boss round with the weight after he ludicrously agreed to this project for a client without doing any research...)
Suppose we want to select the data from the database then we write the query for that. Example:
SqlConnection con=new SqlConnection(Connetion name) string selectPkId = @"SELECT PK_ID FROM TABLE" SqlCommand cmd=new SqlCommand(selectPkId ,con);
So,my question is that why we basically use @ before the sql query.If I don't use @ before that then it again work fine (does not give any error), then what is need of using "@"?
i have the dataset with one table.Table contains three column like 'Name','Location','Pin'.I would like to move the data from another table based on schema.
View 2 RepliesHow do I create a schema.ini file from a tab delimited file?
I have this so far:
[myFile.txt]
ColNameHeader=True
Format=TabDelimited
CharacterSet=ANSI
I think I need something like this after my last line from above:
Col1=first TEXT width 150
My text file has 7 columns, the first row is the header row. The data comes from a Micosoft SQL Server Database where the fields are of the following types:
int
nvarchar(MAX)

I am using VS2008 and oracle 10g ODP.Net. The oracle database that I used in the connection is working and tested it using sql plus.The connection string when used in a GriDView works perfectly. Now when I created a new listview control with the same connection it gives an error.Database schema could not be retrieved for this connection. Please make sure connection settings are correct and the database is online

Now I would like to put the project into the Dev server. What do I do in terms
1- putting my web project into the Dev machine so that we can test it on the Dev server?
2- how do I put the login database schema into Dev? Is it just a matter of restoring my local DB into Dev?...
