hi, I'm having this application using the express way to create the dategridview by having the query string builder. However, my computer recently crashed and I have no idea to change the connection string. so when I load the whole windows application, I am unable to view the information that are supposed to be in the datagridview. however, it returned an exception. after finding out the main culprit, I realised that the database is using the old sql server's login. since it is using the old database's login, therefore it is unable to log the information into the datagrid view. Please help! Thanks.
On a 64bit Itanium cluster, I'm having a problem dynamically setting the ConnectionString of a TextFile Source using the "EvaluateAsExpression" = True and setting the ConnectionString using an expression from a variable. I get the error message:
-1073647612,0x,The result of the expression "@[User::vFullFilePath]" on property "ConnectionString" cannot be written to the property. The expression was evaluated, but cannot be set on the property.
This is not a problem at all on a 32bit machine. I can run the same package on 32bit and it runs fine.
The funny thing is, I'm able to dynamically change the ConnectionString of a Logfile that we're writing all of the errors to, which I believe is using a TextFile Destination connection under the covers somehow (I'm using the SSIS Logging, to a textfile).
I am trying to loop through databases to gather information.
However if i loop though datbases in a cursor, by using a select from sysdatabases, once i am in the cursor and SET @Sql = 'use ' + DBName and EXEC(SQL), the database context never changes from the one the cursor is executing in.
Is there a way to loop through database contexts and execute sql ?
I have 30+ databases in sql 2000. I want to dynalically loop though each of the databases and alter a column named 'EmpName' for all the 'Employees' tables in that database. Here is my attempt.use Master go declare @SQLString Nvarchar(1000) declare @DBName Nvarchar(100) declare @SQL2 NVARCHAR(1000)declare @TABLE_NAME NVarchar(100) DECLARE curDB CURSOR LOCAL FORWARD_ONLY STATIC FOR SELECT name FROM sysdatabases OPEN curDB FETCH NEXT FROM curDB INTO @dbname While @@FETCH_STATUS=0 Begin SET @SQL2 = 'USE ' + @DBNAME + ' ALTER TABLE ' + @TABLE_NAME + ' MODIFY EmpName varchar(100)' from information_schema.tables where table_type = 'BASE TABLE' and table_name like '%Employees%' PRINT @SQL2 EXECUTE SP_EXECUTESQL @SQL2 fetch next from curDB into @DBName end Close curDB End When i execute the above script in master, it says 'Query executed successfully' but when i see the all the Employees table in each of the database, the required change is not made. Can anybody explain this or give an alternate solution?
I am using Sql Server 2000. I have about 25+ databases . I want to run a series of commands on each database... how can I change the database context - the current database - dynamically in a loop... something like this below:
declare @SQLString Nvarchar(1000)
declare @DBName Nvarchar(100)
declare @SQL2 NVARCHAR(1000)
declare @TABLE_NAME NVarchar(100)
While @@FETCH_STATUS=0
Begin
SET @SQL2 = 'USE ' + @DB_NAME + ';GO;ALTER TABLE ' + @TABLE_NAME + ' MODIFY Name varchar(100)'
PRINT @SQL2
EXECUTE SP_EXECUTESQL @SQL2
End
I am getting an error when i run the above commands: Msg 170, Level 15, State 1, Line 1 Line 1: Incorrect syntax near 'GO'
What different are there between connectionString (Part 1) and connectionString (Part 2) in web.config The CCWW is my PC's name, normally I can connect to the database ASPNETDB.MDF correctly either Part 1 or Part 2 in a web page,After I open Database Explorer panel and browse ASPNETDB.MDF, I can't connect to database using Part 2 when I open a webpage in Microsoft Visual Web Developer 2005 Express Edition,but I can correctly open a webpage using Part 1 after I open Database Explorer panel. What different are there between connectionString (Part 1) and connectionString (Part 2) in web.config? I guess while I use Part 1 to connect, maybe it will be cancel exclusive method of the database ASPNETDB.MDF first, but when I connect to database using Part 2, maybe two programms both Part 2 and Database Explorer visit ASPNETDB.MDF at the same time!

I have completed a windows db app. I have saved the db files in the application/bin/ folder. The connectionstring that i am using is
Code:
sql Server =(local);Data Source=.SQLEXPRESS;DataBase=;Integrated Security=SSPI
say i wanted to install this app on my home computer, does not have sql express or anything installed. Now i want to use the application and it must read/write data from the sql db that was saved in the application/bin/ folder. what is the connectionstring then ?
can anyone please help ? what im trying to say is that the application must work independent from any SQL manager/express etc.
I have changed connection string property of connectionmanger at runtime and saved package.But my new connectionstring is not persisting, i am getting my old connection string after reload package .

Hi, does anyone knows where can i find all the values that support the connectionstring??? since the connectionstring uses the "server=local;database=nortwind;UID=me...."
etc. are there more parameteres to specify ?? which one of them is not REALLY important?, where can i find a list or something about it??
When I create typed datasets (for SQL Everywhere db) using the VS designer, I get a connectionString like Data Source =".App_DataDb1.sdf" added to the settings file by the designer. This works fine in the designer but not at runtime. If I replace the settings value to Data Source ="|DataDirectory|App_DataDb1.sdf" then it works fine at runtime but breaks the designer. I looked at the typed dataset designer generated code & it creates a SqlCeConnection object which supports |DataDirectory| macro. So, how can I get the designer & runtime to agree on a connectionString. I guess I can create a partial class for the table adapters & force a connectionString at runtime via a constructor overload, but, is that my only option?
Btw, the error I get at runtime when using the designer generated connectionString is: "The path is not valid. Check the directory for the database."
Hi all, I want to connect to an SqlServer database and I have given the connectionstring on an WinXP computer as Dim ConnectionString As String = "server='localhost'; trusted_connection=true; Database='domains'" Now, when I copied the files to another computer which is Win 2003 Server, I had to give the connectionstring as Dim ConnectionString As String = "workstation id=INFO0;packet size=4096;integrated security=SSPI;data source=INFO0;persist security info=False;initial catalog=domains" Now, I want to upload the files to a website called "BrowseNow.com". What should be the connectionstring when the files are being uploaded to the server. I want the public to read from and write to this database tables. Is there anything I should do witht the SQL Server Enterprise Manager? Thanking you in advance, Tomy
In short, I have a couple grid views on a page that are used for editing as well as sorting, etc. The grids are setup to use the SqlDataSources. I'm trying to deploy this to a server environment for different instances (test,cert,prod) and am trying to set the ConnectionString for the SqlDataSource in the code behind (Page_Load()). Everything works well, except, I get an error message that says the "ConnectionString Property Has Not Been Initialized." Its a javascript alert coming up on top of the grid view. Here is how I'm trying to set the ConnString in the Page_Load():this.EmployeeTimeCardDataSource.ConnectionString = ConfigurationManager.ConnectionStrings[connStr].ConnectionString; Here is an example of the DataSource.<asp:SqlDataSource ID="EmployeeTimeCardDataSource" runat="server" SelectCommand="sp_Select_Managers_Employees_List" SelectCommandType="StoredProcedure"> <SelectParameters> <asp:SessionParameter Name="CurrentUser" SessionField="User" Type="String" /> </SelectParameters></asp:SqlDataSource>
I am getting an error message that says that my connection string has not been intialized I have initialized it. Dim AirliquidiConn As New SqlClient.SqlConnection(ConfigurationManager.AppSettings("AirliquidiDatabase")) Any suggestions??
Hi all This is the code in my web.config file. <appSettings> <add key="ConnectionString" value="server=127.0.0.1;database=testdb;uid=sa;pwd=sa"/> </appSettings> When I'm connecting to the sqlserver database,the page shows that The ConnectionString property has not been initialized. The code that I used to get the "ConnectionString" as belows using System.Configuration; protected static string connectionString =ConfigurationSettings.AppSettings["ConnectionString"]; public static object GetSingle(string SQLString,params SqlParameter[] cmdParms) { using (SqlConnection connection = new SqlConnection(connectionString)) { using (SqlCommand cmd = new SqlCommand()) { try { PrepareCommand(cmd, connection, null,SQLString, cmdParms); object obj = cmd.ExecuteScalar(); cmd.Parameters.Clear(); if((Object.Equals(obj,null))||(Object.Equals(obj,System.DBNull.Value))) { return null; } else { return obj; } } catch(System.Data.SqlClient.SqlException e) { throw new Exception(e.Message); } } } }
These code works well on my machine.When running on my colleague's machine ,the page show that exception. Any ideal?
