I thought so, but that code is generated by the SP, and I am having trouble with the quotation/apostrophes that properly encase each one. Could you help me and show me how to edit the SP itself?

set @sql=@sql+'update tbl_swbom_checklist_testers set '+@COLUMN+'='''+@VALUE+''' '
set @sql=@sql+'where tester='''+convert(nvarchar(100),@tester)+''' and package='''+convert(nvarchar(255),@package)
set @sql=@sql+''''
Ended up looking like that, if anyone was curious.

Instead using four single quotes then use CHAR(39)
set @sql=@sql+'update tbl_swbom_checklist_testers set '+@COLUMN+'='+CHAR(39)+@VALUE+CHAR(39)<br />
set @sql=@sql+' where tester='+CHAR(39)+convert(nvarchar(100),@tester)+CHAR(39)+' and package='+CHAR(39)+convert(nvarchar(255),@package)+CHAR(39)
Hope this helepd you.

Hi All,
i want to edit DataSet value before binding to GridView. How can i do that..?
conn.open();
string result="select name,address,age";
sqlCommand cmnd=new sqlCommand(result);
sqlDataAdapter ad=new sqlDataAdapter(result,conn);
DataSet ds=new DataSet();
result.Connection=conn;
ad.SelectCommand=result;
// in here i want to edit (divide age value by 2) before bind data to gridview.
ad.fill(ds);
GridView1.DataSource=ds;

i want to divide age value by 2 before bind data to gridview.How can i do that...???
Thank you very much .....

A DataSet object is a collection of DataTable objects. You could loop through the table and update the age with something like this:
For Each row As DataRow In ds.Tables(0).Rows<br />
row("age") = row("age") / 2<br />
Next
Or you could just do it in the select by changing your select statement to this string:
"select name, address, age/2 as age"
Hope this helps.

For Each dr As DataRow In ds.Tables(0).Rows
dr("ColumnName") = (dr("ColumnName") / 2)
Next
Where ColumnName is your data column in the DataSet Table.

Hi Guys,
I'm in need of your help.
my problem is, i have two tables namely MASTER and LINECONTENT.
"MASTER" table contains 5,00,000 records,
The columns in MASTER table is
masterid int, masterdesc varchar(1000).
"LINECONTENT" table contains more than 1000 records &
its columns are pageno int, lineno int, content varchar(2000).
I want to compare each row of "MASTER" table, masterdesc column value with the "LINECONTENT" table content column,
If any records matched i want to take the matched master record and store it in another table.
for this i used the below query.
select b.* from linecontent a
join master b on a.content like '%'+b.masterdesc+'%'
but this query is taking much. more than 15 minutes
i want to decrease the time give me some suggestions handle this problem
thank you
regards,
prakash

Throw an index on MasterDesc
Try and use charindex in the where clause - it may not help, just an idea.

Hi,
Thanks for your reply.
sorry i forgot tell you that i have created nonclustered index in both tables. In "MASTER" i have created non-clustered index for masterdesc column similarly in "LINECONTENT" table i have created non-clustered index for "content" field. even though its taking time.
thanks & regards

Putting an index on masterdesc will not make any difference to this query because you are using a leading wildcard: LIKE '%abcde%'. The query optimiser will not even try to use an index for this: it will just go through the rows one by one checking each in turn, because that's all it can do.
So basically the query will take every row in LINECONTENT and test it against every row in MASTER. That's why it's taking so long.

Hi,
but my functionality is like that. i want to compare "master" table with "linecontent" table and matching rows should be taken. so i have written like that but its taking nearly 15 minutes. i want to decrease the time to some 2 to 3 minutes. please tell me the solution
Thanks & Regards,
P.Prakash

I understand what you are trying to do. The problem is that a leading wildcard search is a performance killer, end of story. There is no quick fix or easy answer.
Depending on which version of SQL Server you are using, you may be able to use Full Text indexing. I can't remember whether that was added at SQL Server 2005 or SQL Server 2008 off the top of my head.
Otherwise, I would recommend looking at something like Lucene or Microsoft Search Server to see how they work, as they do something similar to what you are trying to achieve.

I wonder if he tested charindex and if it give a better performance. I would be surprised if it did but needs testing.

Try this
select master.masterdesc <br />
from master ,linecontent<br />
where master.masterdesc = linecontent.content<br />

I use IDENT_CURRENT to predict the next identity on a table (I know I have to be careful).
IDENT_CURRENT return the SEED value (1) for a never populated table
(it's a bug...https://connect.microsoft.com/SQLServer/feedback/ViewFeedback.aspx?FeedbackID=297781[^])
and the same value for an empty table with 1 rows inserted and deleted.
so when IDENT_CURRENT return 1 I don't know if the new identity value will be 1 or 2.
I have to exec:
DBCC CHECKIDENT ('table_name', RESEED, 1) --if a table was empty and never populated
DBCC CHECKIDENT ('table_name', RESEED, 0) --if a table was empty and just populated
in this way IDENT_CURRENT will return always 1.
I'm searching for a more elegant solution than, for an empty table, insert a dummy row, get the IDENT_CURRENT and delete the dummy row!
Many thanks to all

Why don't you use a "select count(*)" statement to determine if the table has any rows in it ? I must be missing something.

Ok, I try to explain better.
I want to predict what will be the next identity value for a table.
If a table have 1 row inserted and deleted, the table is empty and populated.
I this case IDENT_CURRENT return 1 and the next id value will be 2. Correct.
If a table is empty and never populated IDENT_CURRENT return 1 again (it's a bug) and the next id value will be 1. In this particular circumstance i can't predict the next id value and i would like to kown a way to check if a table was populated or not.
"Select count(*)" don't solve the problem.
Anyway many thanks!

If your identity field is called something like myIndex, why not just do something like
DECLARE myCounter INT
SET @myCounter = SELECT MAX(myIndex) FROM myTableName
DELETE FROM myTableName WHERE myIndex = @myCounter
