Updating a dataset Nigeria errotic chat room

However, you can also use different adapters, for example, to move data from one data source to another or to update multiple data sources.

If you aren't using data binding, and are saving changes for related tables, you have to manually instantiate a variable of the auto-generated Table Adapter Manager class, and then call its Udpate All method.

The general form of the UPDATE statement is If the master data set contains an observation that does not correspond to an observation in the transaction data set, the DATA step writes that observation to the new data set without modification.

An observation from the transaction data set that does not correspond to any observation in the master data set becomes the basis for a new observation.

All nonmissing values for variables in the transaction data set replace the corresponding values that are read from the master data set.

SAS writes the modified observations to the data set that you name in the DATA statement without modifying either the master or the transaction data set.

The new observation may be modified by other observations from the transaction data set before it is written to the new data set.Visual Studio 2003 C# SQL Server 2000 I have a dataset on my form.
