Constraints

Data entry constraints are rules that govern the values you can enter in a field. If you want to make sure that the values users enter in a field meet certain conditions, specify a data entry constraint for that field.

You can specify data entry constraints in the Inspector when you create or modify a table that supports them, such as Paradox tables or the new DBF7 format. Old .DBF tables do not support data entry constraints.

IMPORTANT: Do not set the constraints property unless you are creating a new DBF7 table or you wish to update an older table to the new DBF7 format.

Language

Language drivers are special files that determine the character set available on your computer and how characters sort. This property lets you change the driver, but only when you start and before you save a new table.

Displays the date when the table was last updated.

primaryKey

Displays the primary key field.

recordCount

Displays the number of records in the table.

tableType

Displays the current table type and lets you switch between dBASE and PARADOX types. Note that if you switch types, a new table is opened.

version

Displays the current version for the selected table type, as set in the BDE Administrator.
