Is there a simple way to check which fields have altered and update these fields (ie - add a *c* in at the start of each field)??
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
I want to compare two data tables to find out any idetical row are there, and my project not support linq ...

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.
That is
TblOne
Prod Qty
A 2
B 2
C 3
TblTwo
Prod Qty
A 1
B 2
C 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.
Assume in my table named school has a column named StudentNo
I try this script
select * from school where StudentNo <> 'AA'
I just wondering why this where clause "where StudentNo <> 'AA' always return false when StudentNo is null?
How can I loop through each column and determine what data is different in the two said data tables?
View 6 Repliesusing c#, i have an array where i want to test every single line of this array if it is already contained in a table of a database. if not, i do an insert. the test if the line is already in the table is performed using update, if update fails i insert the line. this works BUT the table contains 100000 entries, the arrays i want to compare/insert contain appr. 5000 entries. so, i is really slow and takes minutes.

I'm trying to compare a parameter of type String with a database field of type ntext. Below is my vb code. carDescription is a field in the database table that is of type ntext. The code didn't work because you can't use the equality operator.

Dim carDescriptionLookupCmd As New SqlCommand(carDescriptionLookupCmdString, dbConnection)
carDescriptionLookupCmd.Parameters.AddWithValue("@description", description)

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?
My application uses DataRows and they are not serializable. Is there any workaround for the same?

View 1 RepliesFrom using the command: EXEC sp_spaceused on a SQL 2008 database,
the DB has a size of 642.56 MB, unallocated space 148.77 MB.
I can also see the size of the individual tables from the same command:
Reserved: 103656 KB
Data: 98264 KB
Index_size: 2656 KB
Unused: 2736 KB
What I don't quite get is why the total database size is 642.56 MB when the size of the individual tables is so much smaller. We pay for the total amount, in chunks of 500 MB. I was trying to see which tables where causing the DB to be so big, but to me, it looks like it is not the size of the tables but something else.
What should I look at to figure out why we are taking up so much space? Am I not understanding how this works?
I want to know that how many tables we can have in database and what is the maximum no. of columns.I also want to know the maximum size for each datatype.
