Long Text field property reference
When you use Design view to add a Long Text field to a table, you can set and change a number of properties for the field. This table lists the Long Text field properties and describes what each one does, including the implications of setting or changing the properties.
Property | Usage |
|---|---|
| Format | Enter custom formatting characters to define a display format. Formats defined here appear in datasheets, forms, and reports. |
| Caption | Specifies the name of your Text field. Property accepts up to 2,048 characters. If you don't specify a caption, Access applies the default field name. |
| Default Value | Automatically assigns the specified value to this field when a new record is added. For example, if you specify a value such as "Enter up to 65 KB of text." Doing so would remind users that they can enter 255 characters. |
| Validation Rule | Specifies requirements for data entered into a record, field, or control. When you enter data that violates the rule defined for the field, you can use the Validation Text property to specify the resulting error message. Maximum length: 2,048 characters. For more information about using validation rules, see the article Restrict data input by using a validation rule. |
| Validation Text | Specifies the text in the error message that appears when users violate a validation rule. For more information about creating validation rules, see the article Restrict data input by using a validation rule. |
| Required | When set to Yes, you must enter a value in the field, or in any controls bound to the field, and the value cannot be Null. |
| Allow Zero Length | When set to Yes, you can enter zero-length strings in a field. A zero-length string contains no characters, and you use them to indicate that you know no value exists for a field. You enter a zero-length string by typing two double quotation marks with no space between them (""). |
| Indexed | You can use indexes to speed up queries, sorting, and grouping operations run against large amounts of data. You can also use indexes to prevent users from entering duplicate information. Choices:
|
| Unicode Compression | Access uses Unicode to represent data in Short Text, Long Text, and Hyperlink fields. Unicode takes up more storage space because it uses 2 bytes per character instead of one. To help reduce file size, the default value of the Unicode Compression property for a Short Text, Long Text, or Hyperlink field is Yes. When set to Yes, any character whose first byte is 0 is compressed when it is stored and uncompressed when it is retrieved. Data in a Long Text field is not compressed unless it requires 4,096 bytes or less of storage space after compression. As a result, the contents of a Long Text field might be compressed in one record, but might not be compressed in another record. |
| IME Mode | Specifies an Input Method Editor, a tool for using English versions of Access with files created in Japanese or Korean. Default value: No Control. For more information about using this property, press F1. |
| IME Sentence Mode | Specifies they type of data you can enter with an Input Method Editor. For more information about using this property, press F1. |
| Smart Tags | In Access 2010 only, specify one or more Smart Tags for the field and any controls bound to the field. Smart Tags are components that recognize the types of data in a field and allow you to take action based on that type. For example, in an E-mail Address field, a Smart Tag can start a new mail message or add the address to a list of contacts. Click |
| Text Format | Enables or disables rich-text editing. Select Rich Text to enable rich-text editing. If you enable rich-text editing for the field, and then bind a text box control to the field, you must also enable rich-text editing for the control. For more information about formatting data as rich text, see Create or delete a Rich Text field. |
| Text Align | Specifies the alignment for data in a Long Text field. You have these choices:
|
| Append Only | Determines whether to track field value changes. There are two settings:
Warning Setting this property to No deletes any existing field value history. |
