What I ended up doing is creating a command to execute the following
Select top 1 * from Customers
Then
DataReader dr = cmd.ExecuteReader();
DataTable dt = dr.GetSchemaTable();
The resulting DataTable contains all of the information I need.
Thanks

Thats one way 
Even better would be
Select * from Customers where 1 = 2
Which will give you an empty table and use less resource on the server

This is best handled outside of TSQL since arrays are not a native element in SQL. Therefore, nothing to split the string into.
You can cludge a query using CHARINDEX and SUBSTRING. You will need to add some CASE statements to deal with any missformed data.

Right now I am exporting from SQL 2000, importing this into Access 2003 exporting out to Excel 2003 parsing the data with macros and re importing to Access to run my reports wanted to reduce all the importing and exporting if possible to speed up the process....

It can be done - it will be quicker. The code will be look clumsy.

try this, I guess it will help you.
<br />
select *,left(raw_payload,charindex('+',raw_payload,1)-1),<br />
left(substring(raw_payload, 1-len(left(raw_payload,charindex('+',raw_payload,1)+1)), <br />
len(raw_payload)),charindex('+',raw_payload,1)* charindex('+',raw_payload,1)-1 ),substring(right(raw_payload,charindex('+',raw_payload,1)*3),charindex('+',right(raw_payload,charindex('+',raw_payload,1)*3),1)+1,len(raw_payload))<br />

The left works all the way down the right starts to include the middle and the + sign delimiter,
The data as it goes down increases the characters and some times it has bad data or junk I would like it to delete if it does not match the standard. field one descrption=text field two usage=number and field three adjustables=numbers
Below are the want it and the way it is...

I have written the query(Update,View,Delete) in three Stored Procedure such as SP_GetOfficeHourToday,SP_UpdateOfficeOpenCloseHours,SP_DeleteOfficeHour
How to write the multiple query( View,Update,Delete) in single store procedure using SqlServer2005.

I'm not sure how to answer this because you just write multiple queries in the stored procedure. If it makes you feel better you can put a semi-colon between each query.
|
|
|
|

You can do something like:
Create Proc up_Maintain (@mode char(1))<br />
if @mode = 'a'<br />
begin<br />
....code to add<br />
return<br />
end<br />
if @code = 'd'<br />
begin<br />
....code to delete<br />
return<br />
end<br />
begin<br />
....code to update<br />
return<br />
end
However this is bad practice as the optimiser will optimise for the first time the proc is run. An accepatable alternative is to have a proc like this, but keep the add/delete/update procs and just call thme from the controlling proc, but you gain nothing.
As far as I can see there is nothing to be gained from merging the procs together, but there are potential performance issues, so they should be kept independantly.
Hope this helps

I have return the code in c# application using individual store procedue.
How to write the application code using Multiple query with single stored procedure?
public DataSet GetDayHours(string strSingleDay)
{
//Get the Day,OpenHours and CloseHours from Database
string GetConnection = Connection.GetConnection();
SqlConnection strConnectionString = new SqlConnection();
strConnectionString.ConnectionString = GetConnection;
strConnectionString.Open();
SqlCommand cmdsearch = new SqlCommand("SP_SelectOfficeOpenCloseHours", strConnectionString);
cmdsearch.CommandType = CommandType.StoredProcedure;
cmdsearch.Parameters.Add(new SqlParameter("@DayOfTheWeek", strSingleDay));
SqlDataAdapter daAdapter = new SqlDataAdapter(cmdsearch);
daAdapter.Fill(dsGetDayHours);
}

hi
how to get list of all tables that exist in my sql server instance ?
i'm using this scrpit :
select * from sys.tables
but this command return only tables that exist in Current Database.
thanks

I have a nasty little job where I have a CSV table with 50+ cols which will grow (1-2 per year)
The last 44+ cols are in sets of 3, where AttibuteName changes but the date fields do not.
AttibuteName, Start_Date, End_Date
Therefore the columns are not unique and their number is not stable.
At this point SSIS seems to have a serious issue, however this could be resolved if the import method created cols based on the cols in the source file. I'm quite happy to have the labels in the 1st data row and all data to be varchar as I can deal with this in TSQL but dynamically mapping the new columns is the issue.
Ideally I would like to drop the table(no problem)
Bulk copy into a new table based on the source file
Rename the destination file (no problem)
Process the datavia stored proc (no problem)
I have written an app which does exactly what I want but it is a manual thing and I really want to automate this. Having told the boss that writing ETL apps for each module is wrong, I need to clean this one up.
TIA

Hi
This is nothing ADO.NET but SQL... (not quite sure if this is right forum). I am new to Sybase and today using sqsh (http://www.sqsh.org/[^]) not sure how to "clear screen".
Anyone familiar with this?

May be The title Of the Question Sounds Strange But I Will Explain What I mean ...
I'm Analysing Web Application And I am Very confused
The Problem Is That I didn't use T-sql in Complex Scenario so I don't Know If the T-Sql
Has the Ability To manipulate Date Like .Net Languages In Easy Way ??
Of course I Know That There are loops, conditions , interact With Variables , Builtin Methods
And Etc......
But Is it Easy To Develop , Update .........
Thanks  !

I've seen the best of both worlds. Stored procedures so complex, thousands of lines long and splattered with dynamic sql's and temp tables and numerous loops. And also BLL's having thousands of procedures. In the end, I guess the call is yours, if you're the sole developer. If you're in a team, you might want to leverage your team's skillset.
Developing Business Logic in T-SQL is not for the faint hearted, and is usually lengthier and more complex than a similar implementation in .NET. And T-SQL is pretty limited when it comes to inbuilt functions and constructs. Nowhere near to the .NET libraries, that's for sure. A traditionalist would put his BLL's in the application and use the backend just for DML's.
In the end, it's your call. If your Business Logic is very complex, stick to .NET, else if it's just a few checks and conditions, T-SQL would do just fine.
Alternately if your database server is much more powerful than your web server, you also have the option of using CLR Stored Procedures.

Please don't cross post. I guess this is where it belongs, as your question had nothing to do with VB.
SQL is really easy. Much more so than VB. But, it can get complex, it depends on how complex you need to get, to get what you need. Buy a book.

SQL gives me this error
Server: Msg 242, Level 16, State 3, Line 1
The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.
is there is a way to convert the datetime datatype and how???
