Add JavaScript to handle two scripts in ASP.NET

protected void ApplyJavaScriptForPostToIris()


{

System.Text.StringBuilder sbValid = new System.Text.StringBuilder();

sbValid.Append("if (confirm('Are you sure you want to post this file to app') == true){");

sbValid.Append("this.disabled = true;");



sbValid.Append("} else { return false;}");

sbValid.Append(this.ClientScript.GetPostBackEventReference(this.btnPostToIRIS, "") + ";");



this.btnPostToIRIS.Attributes.Add("onclick", sbValid.ToString());

}

Looping through SQL Server ... This has to be saved. To many hours spent.

I know I will have to do this again....

This article describes various methods that you can use to simulate a cursor-like FETCH-NEXT logic in a stored procedure, trigger, or Transact-SQL batch.


Use Transact-SQL Statements to Iterate Through a Result Set

There are three methods you can use to iterate through a result set by using Transact-SQL statements.



One method is the use of temp tables. With this method, you create a "snapshot" of the initial SELECT statement and use it as a basis for "cursoring." For example:

/********** example 1 **********/



declare @au_id char( 11 )



set rowcount 0

select * into #mytemp from authors



set rowcount 1



select @au_id = au_id from #mytemp



while @@rowcount <> 0

begin

set rowcount 0

select * from #mytemp where au_id = @au_id

delete #mytemp where au_id = @au_id



set rowcount 1

select @au_id = au_id from #mytemp

end

set rowcount 0







A second method is to use the min function to "walk" a table one row at a time. This method catches new rows that were added after the stored procedure begins execution, provided that the new row has a unique identifier greater than the current row that is being processed in the query. For example:

/********** example 2 **********/



declare @au_id char( 11 )



select @au_id = min( au_id ) from authors



while @au_id is not null

begin

select * from authors where au_id = @au_id

select @au_id = min( au_id ) from authors where au_id > @au_id

end





NOTE: Both example 1 and 2 assume that a unique identifier exists for each row in the source table. In some cases, no unique identifier may exist. If that is the case, you can modify the temp table method to use a newly created key column. For example:

/********** example 3 **********/



set rowcount 0

select NULL mykey, * into #mytemp from authors



set rowcount 1

update #mytemp set mykey = 1



while @@rowcount > 0

begin

set rowcount 0

select * from #mytemp where mykey = 1

delete #mytemp where mykey = 1

set rowcount 1

update #mytemp set mykey = 1

end

set rowcount 0

Demystify SQL Debugging with with Visual Studio

Here is what I did to fix this issue "FINALLY"

http://www.asp.net/data-access/tutorials/debugging-stored-procedures-vb
#1 Connect using Windows Authentication as the same account on the local machine that must have sysadmin rights in the Instance of SQL Server.
#2 They use Server Explorer and connect with that same account and then once connect right click on the DB and check "Application Debuggin. I am posting this to my blog.
Great posts. By the way I feel the pain of remote individuals, my answer tell you management that if you want fast, rapid code to fork up the dough for SQL Developer Edition and do all you coding locally with a quality source control.
