data table 2: column employeeid
i want to remove all the employee id's that are in the second table from the first table and display the rest of the values.
Can someone please help me with this.

The CreateJoinTable method in this article provided one solution to your question: http://support.microsoft.com/kb/326080/en-us
Also, dataTable.Merge() is an option to look at.
Last, I suspect you will get a wealth of information from StackOverflow if you haven't already posted this question there as well.
My apologies if your question was not targed at C# as the answer will depend on the target platform you are querying ... SQL Server, MySQL, C# code, etc.
Have a great day.
