Hi,
I am Writing an sql that returns a single record which is row from a table. In the same sql i would like to traverse through the columns of this row. How can I do that? Is it possible to access the columns in SQL through indexing for example like column[1]?
Thanks for your time and help

You cannot refer to a column by it's ordinal (1) in SQL unless you use dynamic SQL in which case you look up the column name from the schema view and build a string to execute.

thanks for your reply. I am using Dynamic Sql but the problem is that I don't know the name of the column to fetch for, thats why I was trying to find a way similar to indexing.Is there a way?

Take a look into the information schema views (under system views in Management Studio) INFORMATION_SCHEMA.COLUMNS is the one you want

hi everybody
i have two tables
table1 with column name
SubmissionDate nvarchar(11)
table2 with column name
submissiondate2 (datetime)
and i insert data in table1 like 17/05/2009 but still in nvarchar format
cos this is my requirement (i mean nvarchar)
my question is i want to insert same date from table1's column to table2's column but dont know how to convert datatype nvarchar to datetime.
when i try to cast i got this error msg
Arithmetic overflow error converting expression to data type datetime.

This is a fundamental error that a lot of newbies make - storing dates as strings. Your dates are stored in a format other than yyyy-mm-dd, probably dd/mm/yyyy and SQL cannot decide between the dd and mm structures, therefore the error.
Try using Convert(datetime,datefield,106)
or one of the other formatters. Under convert/cast in BOL.

thanks holmes for your kind answer
my Problem;
the following code is working perfectly except date. every thing is working perfectly pleas let me know how to add Date into table through following query, and dont worry about other variables these are working perfectly because i have changed them into varchar like this
SELECT @str_Session_Id=CONVERT(nvarchar(10), CONVERT(int, @SessionId))
but i dont want to add date like varchar because i have to compare date with other dates therefore i dont want to convert into varchar.
select @date =(select DATEADD(dd, 1, GETDATE()))
Begin
set @txtSql =
case when (@Std_Count < 3) then 'insert into ProjectRequests values('+ @str_stu_Id+','+ @str_Priority_Id +','+ @str_Project_Id +' , '+ @str_Session_Id +', '+ @date +' , NULL)'
Msg 241, Level 16, State 1, Procedure FUALLY_QUALIFIED_STUDENT_BULK, Line 48
Conversion failed when converting datetime from character string.
any help would be appreciated.

Do some research into parameterised queries, they will make your life so much easier.
Inserting date using a string var is Ok, you just need to format it correctly, the following are valid formats for SQL Server. The important thing is to STORE it as a datetime data type in the database.
yyyy/mm/dd
dd/MMM/yyyy
mm/dd/yyyy
If you try to use a date in dd/mm/yyyy format it will create the error you are getting. MS is a US company so SQL Server used the stupid freakin US date format internally.
Also you need to add additional ' around your date value.

Having installed SQL Server on the same machine where my application
is running, under connection string I could mention Server and Database as follows
ConnectionString = "Server=ABCD-AC93CE29C0\SQLEXPRESS;Database=MyDatabase"
What if SQL server was on a different machine. How do I give the path of that
external machine on which my SQL Server is running?

In my application, I retained membership provided by aspnetdb
For other requirements in the application, I created a database and tables
in my SQL Server 2005.
My problem is I get an error message "Stored Procedure 'abcd' not found.
I have added Stored Procedure using SQl Server Management Studio for that database.
Where could the sp dissappear???
I canot see the sp in SQL Server Management Studio's object browser either!!!
Where could the sp dissappear???

SPs dont just desappear
Probably you created the sp in another DB (maybe the aspnet membership)
You are saying you have 2 DBs, make sure you have 2 connection strings as well and are not trying to access both DB with a single conection string
Dont complicate your life, just recreate the sp in the correct DB

See this[^] setting handlers. To see the insertion/updation/deletion failure/success status, check row_count(). Something like,
--your insert query
IF (<a href="http://dev.mysql.com/doc/refman/5.0/en/information-functions.html#function_row-count">row_count()</a>[<a href="http://dev.mysql.com/doc/refman/5.0/en/information-functions.html#function_row-count" target="_blank" title="New Window">^</a>]> 0) THEN
--insertion success
ELSE
..failure
