Data type Memo

Hello

Does anyone use the data type Memo for a field, and in what situations would you use Memo instead of Text?

Thanks
Nick

RE: Data type Memo

Hi Nick

Microsoft Access provides two field data types to store data with text or combinations of text and numbers: Text and Memo.

Use a Text data type to store data such as names, addresses, and any numbers that do not require calculations, such as phone numbers, part numbers, or postal codes. A Text field can store up to 255 characters, but the default field size is 50 characters. The FieldSize property controls the maximum number of characters that can be entered in a Text field.

Use the Memo data type if you need to store more than 255 characters. A Memo field can store up to 65,536 characters. If you want to store formatted text or long documents, you should create an OLE Object field instead of a Memo field.

Both Text and Memo data types store only the characters entered in a field; space characters for unused positions in the field aren't stored.

You can sort or group on a Text field or a Memo field, but Access only uses the first 255 characters when you sort or group on a Memo field.

regards

Richard

RE: Data type Memo

Hi Richard,

Thanks for that useful information!

I assume the reason why we don't just use Memo for everything is that it requires more memory than text - even if you have an identical fieldsize? Otherwise I don't see the advantage of using the Text data type.

regards,
Nick

RE: Data type Memo

Nick,

That is the main reason, yes.
