Obsolete

Overlap columns were replaced by multi-segment relationships in DataFlex 11.0 and are now considered obsolete.

Description

Indicates whether a given field overlaps another given field.

Type

Boolean, permanent

Access

Values

• True
• False

Remarks

If the first field overlaps the second field given as parameters of the Get_Attribute command, then DF_FIELD_OVERLAP is True. If not, the value is False.

Note that DataFlex supports multi-segment relationships, which greatly reduces (or eliminates) the need for having overlap columns.

Example

Get_Attribute DF_FIELD_OVERLAP Of 11 4 7 To bOverlap

This example checks the fourth field against the seventh field of table number 11. If Field 4 is an overlap field and it overlaps Field 7, then bOverlap (a Boolean variable) will contain True; otherwise, it will contain False.
