is there an easy way to compare two columns in two datatable to see if they match? I need to check if the values in column["x"] of datatable1 occur in column ["y"] of datatable2, without iterating through both tables (for each value in column of dt1, check column of dt2). I tried:
foreach (DataRow dr in dt1.rows)
if (dt2.rows.find(dr["x"]) but this checks the whole row and if finds an "x" in any column, "if" condition is true. I need to only check one column of dt2. Tables have different columns but the same primary column and that's what I need to check

View 5 RepliesWhen attempting to place controls in different content areas using Masterpages and trying to use a compare validator, I get the error: Unable to find control id 'txtStartDate' referenced by the 'ControlToCompare' property of 'cvlDate'. I have also attempted to set it within the c# code behind in page load: cvlDate.ControlToCompare = txtStartDate.ID and by using findControl there must be an easy way to achieve this?

How to do this.
I'm trying to write code for a function that checks dates in a db table and finds the ones that has passed. Example:
tbl Occasion
ID dateStart (smalldatetime) dateStop (smalldatetime)
1 2011-03-29 13:00:00 2011-03-29 14:00:00 //this one won't pass until midnight
2 2011-03-27 17:00:00 2011-03-29 18:00:00 //this one has passed
[Code]....
The formats of 'datevalue' and 'dateStart'/'dateStop' in db are the same, do I need to convert them anyway?
In one of my stored procedure I have to compare two nvarchar datatype values.The values containing both numerical and characters.Which function should I write? And one more problem i.e if a number containing zeros in starting ,I should also match including zeros.But not omit zeros.

It works on the clientside fine, but if a user has javascript disabled then it accepts 071873 which is not a date. Do I need to write a specific serverside function for this validator to work?
When it comes to sort some data, we have two option to sort the data: first one is sort on SQL server with ORDER BY clause, and another is Client side sorting ,how i can choose one option over the other and why? which option is more efficient? with sorting? is there any sorting function with client side sorting? what is the adventage on client side sorting?
View 1 RepliesI have an SQL Function with the following SQL within:
SELECT StockID FROM (SELECT DISTINCT StockID,
ROW_NUMBER() OVER(ORDER BY DateAdded DESC) AS RowNum
FROM Stock
WHERE CategoryCode LIKE @CategoryID) AS Info
WHERE RowNum BETWEEN @startRowIndex AND (@startRowIndex + @maximumRows) - 1
I have a Parameter @CategoryID - however I need to take in a category ID such as "BA" and translated this to a list of Category IDs such as "IE","EG" etc so my WHERE clause looks like:
WHERE (CategoryCode LIKE 'IE' OR CategoryCode LIKE 'EG') AS Info
I have a Lookup Table which contains the "BA" code and then all the real category codes this means such as "IE" and "EG".How do I have the CategoryID expand to multiple "OR" statements in my SQL Function?
At the moment the query as shown can cope with one CategoryID such as "IE", this is done as I want a category page such as category.aspx where a parameter "BA" is passed such as category.aspx?category=BA and this page will list all items with the category codes "EG" and "IE".
The reason I need this is there is a "parent" category code which has multiple "children" category codes which are different to the parent code. I am using ASP.NET and .NET 3.5 on the front-end if this helps.
I am trying to check for a condition such that a date in an input control (textbox) is not greater from a date 1 years from current date(exactly) and also it should not be less than a date 1 year back from current date. for eg. if today's date is "21/dec/1990" then usen cannot enter a date in textbox which is less than 21/dec/89 and it should not be greater than 21/dec/1991. for this i first tried to confirm the greater than condition, i wrote the following code:
<asp:TextBox
ID="TxtSessionFrom"
runat="server"></asp:TextBox>
<asp:CompareValidator
ID="CompareValidator1"
runat="server"
ControlToValidate="TxtSessionFrom"
ErrorMessage="CompareValidator"
Operator="GreaterThanEqual"
Type="Date"></asp:CompareValidator>
CompareValidator1.ValueToCompare=(DateTime.Now.AddYears(1).ToString());
but this gave an error: The value '' of the ValueToCompare property of 'CompareValidator1' cannot be converted to type 'Date'.

There are more than 30 tables in my database.
I need to have a server log that will help to determine the number of items entered into the db and where those items are entered, without having query each table. It should be able to give me the average monthly volume of items input in SQL.
Can this be done using Sql Triggers or any other alternative?
I have to make sure that if I use trigger as the alternative I should have only one table to be updated with all the details of the Updates/Inserts being inserted into the Trigger table after the insertion into the original table.
Below given are some of the create table statements that I have for which I need to have a server log of the updates & inserts.
