I need help w/ setting DataTable.DataType of nvarchar
System.Nvarchar does not exist... does anyone know how to do this?
bulkCopy.WriteToServer throws an exception because it cannot put a string into nvarchar...
dc.DataType = System.Type.GetType("System.Nvarchar");
private void StartImport()
{
Stopwatch sw = new Stopwatch();
sw.Start();
SqlBulkCopy bulkCopy = new SqlBulkCopy("Server=ServerName;Database=test;Trusted_Connection=True;", SqlBulkCopyOptions.TableLock);
bulkCopy.DestinationTableName = "dbo.testSQLBulkCopy";
bulkCopy.WriteToServer(CreateDataTableFromFile());
sw.Stop();
txtResult.Text = (sw.ElapsedMilliseconds/1000.00).ToString();
}
private DataTable CreateDataTableFromFile()
{
DataTable dt = new DataTable();
DataColumn dc;
DataRow dr;
dc = new DataColumn();
dc.DataType = System.Type.GetType("System.Int32");
dc.ColumnName = "c1";
dc.Unique = false;
dt.Columns.Add(dc);
dc = new DataColumn();
dc.DataType = System.Type.GetType("System.Int32");
dc.ColumnName = "c2";
dc.Unique = false;
dt.Columns.Add(dc);
dc = new DataColumn();
dc.DataType = System.Type.GetType("System.Int32");
dc.ColumnName = "c3";
dc.Unique = false;
dt.Columns.Add(dc);
dc = new DataColumn();
dc.DataType = System.Type.GetType("System.Int32");
dc.ColumnName = "c4";
dc.Unique = false;
dt.Columns.Add(dc);
StreamReader sr = new StreamReader(@"d:\work\test.txt");
string input;
while ((input = sr.ReadLine()) != null)
{
string[] s = input.Split(new char[] { '|' });
dr = dt.NewRow();
dr["c1"] = s[0];
dr["c2"] = s[1];
dr["c3"] = s[2];
dr["c4"] = s[3];
dt.Rows.Add(dr);
}
sr.Close();
return dt;
}

Firstly, to get a type object for a built-in type is more simply expressed as just:
typeof( int ) I don't see why using typeof(string) wouldn't work for your requirement, but if you do have trouble, consider using System.Data.SqlTypes.SqlString instead.

Hi all,
I have populated treeview control based on logged in user's credentials under forms authentication. I have used cookies management. The next step is how to render the populated report on reportviewer control. I have tried with following code
ReportViewer1.ServerReport.ReportServerUrl = new Uri("http://servername/Reports");
ReportViewer1.ServerReport.ReportPath = "/" + Request["Path"];
Can any one help me please ?

With what? You haven't stated what your problem is. What is wrong with the code you have posted? Are you getting an error?

Problem is with rendering of the report from tree view nodes to reportviewer control. I gets this error:
The request failed with the error message: -- <html><head><title>Object moved</title></head><body> <h2>Object moved to <a href="/ReportServer/logon.aspx?ReturnUrl=%2fReportServer%2fReportExecution2005.asmx">here</a>.</h2> </body></html> --.

Hi, I am trying to update my local Access DB with data retrieved from my Sybase server. I use this ADO query under the Access ADO connection:
"SELECT * INTO LocalTbl FROM OPENROWSET('ODBC','DATABASE=DB';'UID=USER';'PWD=PWD';'DSN=SYBASE_DSN','SELECT T1.M_SE_LABEL AS BASKET_NAME,T2.M_SE_BSK_COM AS MX_SECURITY, T2.M_SE_BSK_WEI AS WEIGHT FROM SE_MKTOP_DBF T1 ,SE_BKC_DBF T2 WHERE T1.M_SE_INUM = T2.M_SE_INUM AND T2.M_SE_RTYPE = 'INSTR'')"
but get Error number -2147217900 (Syntax error ner FROM)
Can anybody help me with this?
Thanks in advance

Sure, I´ve tried with two Access DBs.
The thing is that I am not sure OPENDATASOURCE/OPENROWSET works with ODBC connections (wonder if someone can clear this up to me). I think I should use OLEDB instead, but have no OLEDB driver installed for Sybase.

Sorry, I'm a liar. I checked with two Access connections and I still get the same Error (-2147217900). Any idea?
Thanks in advace

Hi all,
declare @str1 varchar(500)
declare @str2 varchar(500)
declare @str3 varchar(500)
declare @str4 varchar(500)
select @str1=ud_id from cm_tb_002 where username='admin';
select @str3=role_id from cm_tb_012 where tb012_id=@str1;
select @str4=tb001_id from cm_tb_001 where menu_activ = 1 and child_lvl = 0 and [15]='1';
select tb001_id from cm_tb_001 where menu_prnt=@str4;
Here i want to pass @str3 to a this query
select @str4=tb001_id from cm_tb_001 where menu_activ = 1 and child_lvl = 0 and @str3='1';
but the @str3 column is an bigint column. ex. 15 i.e column name
In sql sever this value is storing as [15] as column name. Now i want to
pass this value to this query
select @str4=tb001_id from cm_tb_001 where menu_activ = 1 and child_lvl = 0 and @str3='1';
Please help me on this.
i want to join this group

You would need to construct your SQL statement as a string and execute it using the EXEC statement.

Hai all
In my table i have some records with serial number
ex:

5.
if i delete 3 means 4 should be decremented as 3 and 5 should be decremented as 4.
Plse give me a logic to do this.

I don't give code to people, especially when they haven't demonstrated that they have tried to solve the problem themselves.
I'll give you a hint though - use an UPDATE query to decrement all serial no. values greater than the one being deleted. Your biog states that you are a professional software engineer, so you should be able to figure out how to implement this.

I assume that you mean that you have an identity column that you want to reorder on a delete. You should know that this is a dangerous thing to attempt. For a start, suppose that you have 10,000,000 records in a table and you delete record number 3. That leaves 9,999,996 records being updated just to keep this in sync. More importantly, if you have this fields as a PK and there are foreign key relationships then you also need to reorder all of those foreign keys. Please rethink this strategy before you attempt to go any further.

If you really need the records to be sequentially numbered in the output of a query, and you're using SQL Server 2005, consider sorting the output using ORDER BY and using the RANK function to get the sequential numbering.

there is 2 table named table 1 and table 2 in the db
where both table have a comman coloumn named employee_code.
let table1 conatain emplyee_code-1,2,6,8,9
and table2 contain employye_coce-2,4,6,7,8
now i want a sql statement which will give me the out put as follows
i want to check(let say employee code1) wather a particular employee_code
present in table 1 and not present in table2 .if it run succesfully it should give massage emplyee code exists else
doesn't exists.
means if i select emp_code 1 then the message would be "emplyee code exists"
i select emp_code 2 then the message would be "emplyee code doesnt exists"

Use the EXISTS[^] operator to check for the existence of rows with a particular employee code in table 2.

I don't follow the table layout, but it looks like you need something like
select sum(count), letter from tbl group by letter
where letter is the column that gives you A/B/C and count is the column you want to combine. use count instead of sum if you're counting columns and not combining their values
