DbSetOrder()

Selects the controlling index.

Syntax

DbSetOrder( <nIndexPos> ) --> NIL

Arguments

<nIndexPos>

This is the numeric ordinal position of the index to activate as the controlling index. Indexes are numbered in the sequence they are opened with OrdListAdd(), beginning with 1. The value 0 has a special meaning: it de-activates the controlling index while leaving it open. Records are navigated in physical order when <nIndexPos> is set to 0.

Return

The return value is always NIL.

Description

DbSetOrder() exists for compatibility reasons. It is superseded by OrdSetFocus().
