After the data in your dataset has been modified and validated, you can send the updated data back to a database by calling the update method of a tableadapter. After changes have been made in a dataset, you can transmit the changes to a data source I use tableadapters whenever i need to talk to a sql database

There will be times when i needed to add/remove a field in my table and whenever you “refresh” the tableadapter, the newly added field tend to become the last column in the column order.
If you want to update your existing columns, delete all the columns out of the table before you attempt to open the query
When you save the query, your updated columns get added back Make sure your connection string has permissions to view column information. The technologies are especially useful for apps that enable users to modify data and persist the changes back to the database Although datasets are a proven successful technology, the recommended approach for new.net applications is to use entity framework core.
Any changes that you make to the tableadapter's main fill method are reflected in the schema of the associated data table For example, removing a column from the query in the main fill method also removes the column from the associated data table. This previously brought up a window asking if you wanted to add database tables, update existing tables, etc., and you click “ok” and it would rebuild your model based on the database, and you can save the.edmx file and any new columns in your table are now available in entity framework. I've made a dataset using the dataset designer, and i'm trying to add a column to reflect changes made to the database (added a column, nothing fancy)
Is there a way to 'refresh' the dataset schema from the datasource without deleting my adapter (and all the methods and queries i've created)?
What can i do to refresh the model to include the new column succesfully I do not want to redo all the relationships and measures from the old table to the new table each time my source schema is updated/changed.
