Inserting into a column with an identity column
I have two tables Alpha and Beta. I want to copy all of the records from Alpha into Beta, except for the "Id" column values of Alpha, which should be ignored. They should be ignored because the Beta "Id" values are auto incremented. So in other words, I just want to copy the "Name" column of Alpha into Beta. Assuming that when the insert occurs, the Beta Id values will automatically be added because they are auto incremented values. Can someone help me write the insert statement. I can't get it to work, because I don't know how to make the insert statement ignore the Id column on insert.

I made a mistake, and did not realize an error I had made, but now my code is working. Thanks.
Glad I could help, while I do not know the purpose, I would recommend preserving the Id reference from alpha table in beta table.
Presumably based on your last comment, you Alpha table was designed in a way that you now see a reason to restructure it.
Preserving the ID will/could maintain other table references to simplify transitions.
I.e. You have alpha, gamma, that have a relationship to alpha's ID. If my guesstimate in the reason is correct, you would also need to transition gamma table as well to match the new beta tables ID column.
