SQL Statement Help

Hi,

In access - I have 1 table with 10,000 usernames 'users', I have a list of 2,500 that need to be deleted.

I was thinking the best was to do this to create a new table 'data_to_delete' with 1 column 'usernames'

Then I run a SQL statement

DELETE FROM users
WHERE data_to_delete.usernames=*;

Any ideas on the correct syntax?

where users.usernames in (select usernames from data_to_delete)

Sort of new problem. I created a test database and when I created a query it populates a textbox for me to enter in data to delete.

Awesome! I still got the same Hyperlink error, and I changed the data type from Long Text to Short Text and that fixed it. Any clue why that is?

The comparison data is LongText

There is no LongText Data type in access. (Only Text and Memo)

In Access use Text for the Data Type for the user field.

where is your data coming from?  mySQL?

Long/short text were introduced in Office/Access 2013, replacing Text/Memo:
