BUG: CREATE SQL VIEW Scrambles the Parentheses in SQL Command

The information in this article applies to:

• Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b, 5.0, 5.0a

SYMPTOMS

If, in a CREATE SQL VIEW command, there are parentheses and a logical OR expression, once the view is added to the database (.dbc file), the parentheses will appear to be moved.

CAUSE

The parser for the view will group the OR statements until it reaches another OR or the end of the statement. It has to do this in order to look correctly in the Selection Criteria of the View Designer.

WORKAROUND

To work around this problem, write the SQL statement without any parenthesis, or if the SQL statement is to complex, break up the statement with the UNION or UNION ALL clauses.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

Steps to Reproduce Problem

Create a program with the following code, with the Tastrade.dbc database file open:

   CREATE SQL VIEW test AS SELECT * FROM customer ;
      WHERE customer.city='London' ;
      AND (customer.country='UK'  ;
      OR customer.postal_code='EC23NT')

 SELECT *  ;
  FROM tastrade!customer;
  WHERE Customer.city = "London";
    AND Customer.country = "UK";
    OR (Customer.postal_code = "EC23NT")
