I have DataSet containing a table. I want to change the datatype of 2nd column of the table to varchar before binding the dataset to my datagrid.
Please help me out

If this is what you want to do then you should change it inside the query to the database.
CAST(Column1 AS varchar(50))

Also, if you only have a single table you should look at using DataTable instead of dataset. This will reduce the overhead of using datasets when you don't need the overhead of a dataset.

I need to do the below:
Import the excel file using the available SQL server tools to a temp db. Then write a mapping between the temp db and the Main database. Move the data to the Main database.
Is this possible??
-----------------------------------------------------------------
where there is a will there is a way
|
|
|
|
|
INSERT INTO TableName(Column1, Column2, etc)
SELECT Column1, Column2, etc FROM #TempTableName
|
|
|
|
|
You should be able to use the oledb provider to link to excel and import the data into a datatable. From there you could use SQLBulk Copy to move the data easily if your column headers are the same, otherwise you will need to map the columns.
If you do not want to this in code then the other suggestion might be better.

You created the db and you don't have permissions?

Hi
You can filter using Month() and Year() functions.
For example:
Month(DateColumn) = 3 and Year(DateColumn) = 2006

Hi Everyone!
I'm trying to create a new database file from XSD schema and then populate the empty SQL database with a DataSet. The major problem is to create a table from XSD schema file. I'm using SQL Server 2005 Compact Edition and VS 2005.
File.Delete("Test.sdf");
string connString = "Data Source='Test.sdf'; LCID=1033; Password=\"s$;2'!dS64\"; Encrypt = TRUE;";
SqlCeEngine engine = new SqlCeEngine(connString);
engine.CreateDatabase();
engine.Dispose();
SqlCeConnection conn = new SqlCeConnection(connString);
conn.Open();
DataSet dbSet = new DataSet("myDataSet");
dbSet.ReadXmlSchema("myData.xsd");
dbSet.EnforceConstraints = false;
dbSet.ReadXml("myData.xml");
...
conn.Close();
Any help would be greatly appreciated.

i have 2 computers. first its name is PC1 with ip 192.168.0.1 and the other PC2 192.168.0.75
PC1 has the SQL database and PC2 should access the database
i do not know how to make PC2 access the Database in PC1...
need help on that please
thanks allot

This answer assumes you are using SQL Server:
The connection string will refer to the name PC2, or you can use its IP address. You must also permit the SQL Server to accept network connections.
|
|
|
|
|
i really need more details...
the .mdf file on PC1 "C:\DB.mdf" ... what should the connection string used on PC2?
and how can i permit the SQL Server to accept network connections.

SQL Server is not a file based database system. It is a server based database system. You cannot connect to files (SQL Server 2005 does give you an illusion that you can, but it temporarily connects the file to the server)
In short: You connect to a server, not a file.

I really need more details... For example, the version of SQL Server.
|
|
|
|
|
from SQL Server Configuration Manager ( Version: 2005.090.3042.00 )
i dont know if thats the version you asked..
about the connection what should i do to make PC1 and PC2 access the same file

You don't you get the sever local to the file access it and then connect to the server. As I already told you: SQL Server is a server based database, not a file based database. You connect to the server.
First, to allow network access:
Go into SQL Server Configuration Manager. Open "SQL Native Client Configuration"-->"Client Protocols" and ensure that "TCP/IP" is enabled.
Then open "SQL Server 2005 Network Configuration"-->"Protocols for <instance name>" and ensure that "TCP/IP" is enabled.
Then go into "Microsoft SQL Server Management Studio" and connect to the relevant server. Once connected, open up the databases. If the database is not there, then right-click on "Databases" and attach the file that you want.
Then in your application you connect as normal, specifying the name of the machine that is running the SQL Server.
