problem in connectionstring

when I write this code in web.config :

<configuration><appsettings><addkey="constring" VALUE="WORKSTATION id=I-85096B7FC8F64;packet catalog='test"/' info="True;initial" security="SSPI;data" source="I-85096B7FC8F64;persist" size="4096;integrated"><system.web>

and write this statements in the code of program :

string Constring = ConfigurationSettings.AppSettings("constring"); SqlConnection conn = new SqlConnection(constring);

this error is displyed:

The name 'constring' does not exist in the class or namespace 'C_sharp1.WebForm1'

In C#, instead of:
ConfigurationSettings.AppSettings("constring")
use square brackets:
ConfigurationSettings.AppSettings["constring"]|||

thanks a lot.

the problem is solved by your solution.

problem dropping columns

One of our developers accidentally added a 'rowguid' column to all of our
tables (mssql 2000). I'm trying to write a script that will drop this
column from all the tables; however, I've run into a problem where I can't
drop them because there are dependant contraints/indexes. The following
code is what I have so far. Is there's a way to identify and drop all
dependancies on this column first?
DECLARE @.TableName sysname
DECLARE @.ColumnName sysname
DECLARE RowGuidColumnList CURSOR
FOR select t.name, c.name
FROM sysobjects t
JOIN syscolumns c
ON (c.id = t.id and t.type = 'U')
WHERE c.name = 'rowguid'
order by t.name, c.name
OPEN RowGuidColumnList
FETCH NEXT FROM RowGuidColumnList
INTO @.TableName, @.ColumnName
WHILE @.@.FETCH_STATUS = 0
BEGIN
PRINT 'Removing rowguid column from ' + @.TableName
execute('ALTER TABLE ' + @.TableName + ' DROP COLUMN ' + @.ColumnName)
FETCH NEXT FROM RowGuidColumnList
INTO @.TableName, @.ColumnName
END
CLOSE RowGuidColumnList
DEALLOCATE RowGuidColumnList
Thanks, DougYou can find information about dependencies of some
particular column from system tables:
sysconstraints,
syscolumns,
sysobjects
Take a look about this tables in BOL.

Problem correctly setting a local_variable

Hi,

I've been trying to write a stored proc to no avail. I'm trying to set a local variable and every time I try to execute the stored proc I get the following error:

Running [dbo].[StoredProcedure2].

Conversion failed when converting the nvarchar value 'TEST2' to data type int.

No rows affected.

(0 row(s) returned)

@.RETURN_VALUE =

Finished running [dbo].[StoredProcedure2].

Here's the code (which I skimmed down to try and pinpoint where the issue was).

Initially, I was trying to assign a numeric string value stored as nvarchar(10) and anytime the value would be over '2147999999' (in that area) it would bomb... Now even this simple code won't work and I can't understand why. If anyone would be kind enough to enlighten me ;-)

ALTER PROCEDURE dbo.StoredProcedure2

AS

DECLARE @.ME NVARCHAR(10);

SET @.ME = 'TEST2';

RETURN @.ME

u must use Print/Select instead of Return.

fromBOL

RETURN

Exits unconditionally from a query or procedure. RETURN is immediate and complete and can be used at any point to exit from a procedure, batch, or statement block. Statements following RETURN are not executed.

Syntax

RETURN [ integer_expression ]

alter PROCEDURE dbo.StoredProcedure2

AS

DECLARE @.ME NVARCHAR(10);

SET @.ME = 'TEST2';

select @.me

The value following the RETURN keyword MUST be an integer value.

Strings are not allowable RETURN values.

Instead use:

Code Snippet

ALTER PROCEDURE dbo.StoredProcedure2

AS

DECLARE @.ME NVARCHAR(10);

SET @.ME = 'TEST2';

SELECT @.Me

GO

It always better to use OUTPUT parameter, or Select statement to get the single row & column data from the SP. Return only supports integer.

NOTE:

PRINT – you can’t get the result on the UI. It will get suppressed.
