A5_field_getKeyColumns Function

Syntax

Arguments

dbfTableName

The table to query for 'primary key' columns.

Description

Return the name of the 'primary key' columns of a .dbf table. .dbf tables do not use primary keys. However, you can infer the 'primary key' if the table has an auto-increment column, or a 'unique value' field rules.

Example (for tables in Alphasports):

?a5_field_getKeyColumns("customer")
= "CUSTOMER_ID"
 
?a5_field_getKeyColumns("invoice_items")
= INVOICE_NUMBER
PRODUCT_iD
