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.
