BUG: Repeated Fetch With Dynamic Cursors and OR Clause

ID: Q119107

The information in this article applies to:

Microsoft SQL Server Programmer's Toolkit, version 4.2

BUG# 10103 (4.2)

SYMPTOMS

Opening a dynamic or forward cursor with a query involving an OR clause may cause an inability to retrieve rows past the row set returned by the first fetch.

WORKAROUND

Placing the WHERE clause of the query in parentheses, for example,


    "select au_id from authors where (state > 'K' OR city > 'G'")

will cause the cursor to function as expected. Keyset driven cursors do not display this problem and can also be used as a workaround provided the result set is not prohibitively large.

STATUS

Microsoft has confirmed this to be a problem in Microsoft DB-Library 4.20. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
