after a complex sql script I finally get temp table like this
No Invalid Port
1 AA,BB,CC,AE,CD,LA,SE,GE,XX,A2,A3...
2 PO,FD,SE,LE,SE,AQ,GB,NK,NA,OM,IA,JO,YA,LL,EN...
then I will use this temp table to join with another table to get the finally result like this
No Invalid Port Start No EndNo
1 AA,BB,CC,AE,CD,LA,SE,GE,XX,A2,A3... AA QO
2 PO,FD,SE,LE,SE,AQ,GB,NK,NA,OM,IA,JO,YA,LL,EN... BB QP
I have problem here.. the Invalid Port list will be a very very long string.. I want to insert symbol to this field (each 2 ports with one symbol)

View 2 RepliesI already may have access to the solution i am after but cant find a way to keep the data and schema the same during deployment, ie development server SQL database to be the same thing as what i put on the sql server host during the deployment of the web application
i was using Quest Rocket compare to sync data and schema, it worked fine but they dropped that project with the intro by MS of VS08, ie the Quest plug-in works in VS05 but not in VS08 anyway, i probably have the solution I am after at my disposal due to my MSDN subscription which includes SQL server products, but my first problem there, is that i cant identify which MS tool to download and to use that will do the same thing or better than the Quest Rocket compare product,
i believe the solution i need is the full version of SQL Management Studio (which i think i have due to my MSDN subsctiption but my second problem 2) is i cant find in that full studio download in my MSDN subscriber area) also is it only the full verison of SQL Mgt studio and not the Express version that might have the "sync" capabiltiy, is that correct? or is there a way (I am a intemediate on SQL techonologies), within the Express Management Studio to painlessly sync both the schema and the data? I am using VS08 Pro, so mayber there is a way in the VSIDE to do the syncing, I think i tried the Publisher but ran into difficulties, am going to try that again and repost here what those difficulties were,
SO really just after a nice tool or utility that will keep SQL database schema and data the same during the deployment process for the web application i build, kinda urgent to as am buried and dont have time to breath.
I'm using SQL Server Management Studio Express 2005. I have a database that I'm trying to make an exact copy of under a new name. I generated a script, made a new database then ran the script on it. My problem is the new database is short two objects, it shoudl have 840, but has 838.
I need to find out which two objects are not there.
Maybe there is a way to copy the exact database under a new name? I tried to detach, copy to a new name and then attach, but that did not work.
I have two datatables with same columns. I want to compare those two tables and I want to know whether data in those tables is same or different. If both Prod and Qty are same then I have to get true or else false.

A 2
B 2
C 3
TblTwo
Prod Qty
A 1
B 2

As of now I am looping thoruh all the rows. Is that the only solution or is there any best way to do this ?
I have 2 Linq to Entity queries, here they are:
[Code]....
In "query" there are several columns, 2 of them are NIIN and Qty. In "objViewDDRT" there are only 2 columns, they are NIIN and AvailBalance.
What I need to do is for each row in "query" check to see if the NIIN is in "objViewDDRT", and if it is get the AvailBalance for that NIIN from objViewDDRT.
I want to make some check before I add a list of data
so I create a temp table
[Code]....
and this is the qeury I retrive from DataBase
[Code]....
so now I get 2 data resultI just want to knowhow to compare these 2 data result?
[Code]....
then now allow to add new data...

I have a textbox that takes an integer value, and a submit button that when clicked passes the value to a detailsview to display the database record at that index.
What I'd like to do is, when the button is clicked, compare the number to the keys in the detailsview's datasource so that if the record ID doesn't exist, I can display a label telling the user that the ID# doesn't exist.
How would I go about doing this? Is there some sort of compare method for the datakeynames property?

I need to retrive a value from a column of a table per stored proc. This is usually an integer, but also can be null. I get this value and store it in a session variable.
Later, I need to pass this same session variable to another stored proc.
Session["myVariable"] = ds.tables[0].rows[0][1]; // this can be null or an integer
somewhere else in the project, I need to pass it to another stored proc exactly as received.
