DataSource Controls :: Compare Data In Two Datatables?
Jun 30, 2010
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 need to compare 2 DataTables that do not necessarily have the same structure. One dataTable is the master (dtDB), the second dataTable (dtFORM) is what will have the changes, if any, but not necessarily all of the columns of dtDB. In both tables the first column will be the primary key and all columns that dtFORM has, dtDB will have.
There is another DataTable (dtResults) that will flag the differences
This is where I am at so far:

I have two DataTables, with Different Columns. Some of the Columns are same between them.
i am looking to do this.It is also refered to as MINUS and is simply all the rows that are in the First table but not the Second.
These three colums are same between the two tables.
string[] strCols = { "CustomerID", "CustomerName", "CustomerCity" };
I tried this but it seems to return all the Rows from the Table1.

The case is: I use a webservice that gives me information about companys. For example: I entered a companyname and the webservice give me a list of al company's in the country. The webservices return a one dimensional array. The problem is that I must search in two register so the webservices returns 2 array's. I put the data from both arrays into 2 datatables. The data in the 2 datatables can be different or the same.
The question is: How could I matching the data on ID and combine the data into 1 datatable.
The code:
//Create result
SearchResult Result1;
SearchResult resultZoekmogelijkheid2;
//send van Soap Request
[Code]....

I 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 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'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.

using 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.

Among the many aspects of asp.net that I haven't focused my development on yet is caching. I have a perfect application for it now, I think, with a GridView that sits inside a repeater, and is bound in the Repeater ItemDataBound event. The contents of the GridView will remain static for each Repeater data item for each Client. The nature of the data in the GridView is that it can change from day to day per Client, but wouldn't need to be refreshed more frequently than that. The Page istelf only deals with one at a time Client based on a QueryStringParameter. My questions are a) how do I cache the DataTable so that a call to the DataBase isn't made each time Repeater item is bound and b) can I create/cache multiple DataTables (one for each Client) and let them live for day, checking for existence before calling the SQL stored procedure to regenerate the data?

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 carDescriptionLookupCmdString As String = "SELECT carMake FROM car WHERE carDescription = @description"
Dim carDescriptionLookupCmd As New SqlCommand(carDescriptionLookupCmdString, dbConnection)
carDescriptionLookupCmd.Parameters.AddWithValue("@description", description)
Dim reader As SqlDataReader = carDescriptionLookupCmd.ExecuteReader()

When 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?
<asp:Content ID="Content4" ContentPlaceHolderID="leftForm" Runat="Server">
