Linking tables

If I link 2 pieces of information in 2 tables and one is deleted or removed, will there be some message that informs me of this?

RE: Linking tables

Hi Jordana

Thank you for your quesiton. The feature you are referring to is called Referential Integrity. It can be set when the relationship is created between the tables. Microsoft have an article describing the options:

I hope this helps - do let us know if you have any further questions.

Kind regards,
Andrew

Access tip:

Choosing data types in Access

Not sure which data type to use for your Access fields? Here are some guidelines to help you choose a data type to assign to a field.

- The Text data type can accept up to 255 characters. For information that will be recorded in paragraphs, use Memo.

- Also use Text for numbers that aren't going to be used in calculations, e.g. phone numbers.

- Use the Currency data type for monetary amounts.

- Use Date/Time for dates.

- Most other numbers can use the Number data type, but the Field Size property may have to be altered.

- For fields that have only two alternatives (yes, no) use Yes/No data type. If there is likely to be a third entry option (e.g. maybe or don't know) use Text instead.
