PRB:Double Quotes in Remote View Filter Expression Cause Error

• Microsoft Visual FoxPro for Windows, version 5.0

SYMPTOMS

If the Filter expression of a remote view uses double quotes, then running or modifying the view causes the following error message:

   Connectivity Error........invalid column name....

CAUSE

Microsoft SQL Server version 6.0 and up uses single quotes (') for string constants and double quotes (") for identifiers with spaces like "my table," "my column," and so forth. You must convert double quotes to single quotes in the View Designer, before the example constant is included in the SQL string.

WORKAROUND

Use Single Quotes ('   ') instead of Double Quotes ("  ").

   CREATE SQL VIEW test;
     REMOTE CONNECTION "myConn";
     AS SELECT Authors.au_id, Authors.au_lname, Authors.au_fname;
       FROM dbo.authors Authors;
       WHERE Authors.au_lname = 'B'

STATUS

This behavior is by design.

MORE INFORMATION

Steps to Reproduce Behavior

1. Use the 32-Bit ODBC Manager to create a DataSource to the PUBS database on a Microsoft SQL Server.

2. Open a Database or create a new one.

3. Create a Remote View based on the DataSource created in step 1.

4. Add the Authors Table to the View

5. Select three to four fields from the table

6. Click the Filter tab, create and select a character type field such as "Authors.au_lname," and select any criteria, for example, "=".

7. Add "A," with the double quotes (" ") as the expression.

8. Right-click the Query Designer and click Run Query from the shortcut menu.
